Mounted on 5.0mm (.013mm thick) land areas. 2. Measured on 8.3ms, single half sine-wave or equivalent square wave, duty cycle = 4 pulses per minute maximum. 3. ZENER VOLTAGE (Vz) MEASUREMENT Nominal zener voltage is measured with the device function in thermal equilibrium with ambient temperature at 25 ¢J . 4.ZENER IMPEDANCE (Zz) DERIVATION ZZT and ZZK are measured by dividing the ac voltage drop across the device by the accurrent applied. The specified limits are for IZ(ac) = 0.1 IZ, (dc) with the ac freqency = 60Hz. 1SMB5926 THRU 1SMB5956 ELECTRICAL CHARACTERISTICS (T L=30 ¢J unless otherwise noted) (V F=1.5Volts Max @ IF=200mAdc for all types.)
