APPLICATION NOTE Since actual voltage available from given zener diode temperature dependent, necessary determine junction temperature under operating conditions order calculate value. following procedure recommended: Lead Temperature, should determined from: lead-to-ambient thermal resistance (°C/W) power dissipation. value will vary depends device mounting method. generally 30-40°C/W various clips points common printed circuit board wiring. temperature lead also measured using thermocouple placed lead close possible point. thermal mass connected point normally large enough that will significantly respond heat surges generated diode result pulsed operation once steady-state conditions achieved. Using measured value junction temperature determined

worst-case design, using expected limits limits extremes (TJ) estimated. Changes voltage, then found from:
zener voltage temperature coefficient, found from Figures Under high power-pulse operation, zener voltage will vary with time also affected significantly zener resistance. best regulation, keep current excursions possible. Data Figure should used compute surge capability. Surge limitations given Figure They lower than would expected considering only junction temperature, current crowding effects cause temperatures extremely high small spots resulting device degradation should limits Figure exceeded.
