Harris Suppression Products
More than ever before, today's system equipment designers must ensure that every circuit immune voltage transients. This challenge results from combination technological, economic legal factors:
Technological
Electrical electronic devices integral on-going activities business, industry, government, life general. Businesses consumers alike have come expect extremely high levels reliability from these products. However, technology increasing levels complexity make today's devices even more susceptible electrical overstress.
Economic
Components systems risk from exposure voltage transients expensive. Many these components control critical processes shutdowns have potentially devastating effects. maintaining system functionality, adequate transient protection minimize costs such warranty issues.
Legal
Legislation adopted European Community requires that manufacturers wishing sell products legally within European Union must demonstrate that their products within full compliance. Proof compliance includes ElectroMagnetic Compatibility (EMC) testing, based upon test standards developed IEC. These international standards often referenced specified products intended sale outside Europe well. products presented this data book designed suppress voltage transients induced electrical/electronic systems circuits from common sources such ESD, EFT, Lightning Surge, Auto Load Dump, Inductive load switching, capacitor bank switching, noise bursts, etc. Harris Suppression Products comprised five distinct technologies order best application particular transient concerns. This data book organized following manner: Products highlighted Section those familiar with Harris Suppression Products, Section Alpha Numeric Listing references data sheet pages. breadth Harris Suppression Products portfolio, Section categorizes applications into general Market Segments selection appropriate device. those familiar with technologies products, Market Segments provide examples Harris Suppression Products Series that most often chosen likely suited that specific function application. core book comprised Harris Suppression Products Data Sheets, segregated device Series Sections through comprehensive Application Note Section supports each technology device Series.

Electrical products systems that immune voltage transients within their intended application, propagate transients themselves, said have ElectroMagnetic Compatibility EMC. Often today, products must demonstrate compliance through applicable testing. (See application note AN9734.) These tests derived from standards developed industryrecognized engineering, testing safety organizations throughout world including IEC, IEEE, VDE, CSA, CENELEC, NEMA. example importance achieving exemplified through legislation enacted compliance within European Union part mandatory "CE" marking program. Products manufactured each Market Segments table above have various transient voltage test standards associated with them. And, therefore, could subject compliance. Depending upon application, these tests based sources that include: Lightning Inductive Load Switching sources such solenoids, motors, alternator load dump, transformers, etc. Relay contact/circuit breaker operation noise Selection suppression device installation within product would ideally occur during initial design phase, also occurs when finished products fail meet compliance testing. either case, designer would: Identify applicable tests conditions product. Match test criteria suitable suppression device families/technologies. Make final selection based upon suppression device performance/parametric limits product sensitivity level needs such package style, form factor, etc. Verify product compliance through testing.

transient surge rating serves excellent figure merit C-III varistor. This inherent surge handling capability C-III varistor's best features. enhanced surge absorption capability results from improved process uniformity enhanced construction. homogeneity material powder improved control over sintering assembly processes contributing factors this improvement. power mains environment, industry standards (UL, IEC, NEMA IEEE) suggest that worst case surge occurrence will 3kA.

Although this type varistor still functioning normally after this magnitude shift, devices lower extremities tolerance will begin dissipate more power. Because this possibility, extensive series statistically designed tests were performed determine reliability C-III type varistor under bias combined with high levels temperature stress. date, this test generated over 50,000 device hours operation temperature 125oC, although only rated 85oC. Changes nominal varistor voltage, measured 1mA, less than have been recorded (Figure

Should transients occur rapid succession, average power dissipation required simply energy (wattseconds) pulse times number pulses second. power developed must within specifications shown Device Ratings Specifications table specific device. Furthermore, operating values need derated high temperatures shown Figure Because varistors only dissipate relatively small amount average power they are, therefore, suitable repetitive applications that involve substantial amounts average power dissipation.
