*JEDEC Registered Data. NOTES:
When ordering devices with tighter tolerance than specified, hyphenated suffix part number desired tolerance, e.g. 1N3156-2%, 1N3157A-1%, 1N3157-1-1%, etc. Measured superimposing maximum allowable change observed over entire temperature range i.e., diode voltage will exceed specified change discrete temperature between established limits. Voltage measurements performed seconds after application current. 1N3154, 1N3155, 1N3156, 1N3157 also have military qualification MIL-PRF-19500/158 JANTXV level adding JAN, JANTX, JANTXV prefix part numbers well "-1" suffix, e.g. JANTX1N3156-1, JANTXV1N3157-1, etc. Designate Radiation Hardened devices with "RH" prefix instead "IN", i.e. RH3157A instead 1N3157A.
