2. **TOLERANCE AND TYPE NUMBER DESIGNATION** The type numbers listed indicate a tolerance of ± 5%. 3. **ZENER VOLTAGE (VZ) MEASUREMENT** - Nominal Zener voltage is measured with the device junction in thermal equilibrium with ambient temperature at 25 ° C. 4. **ZENER IMPEDANCE (ZZ) DERIVATION** ZZT and ZZK are measured by dividing the ac voltage drop across the device by the ac current applied. The specified limits are for IZ(ac) = 0.1 IZ(dc) with the ac frequency = 60 Hz. - *Include SZ-prefix devices where applicable. **www.onsemi.com** **3** **1SMB59xxBT3G Series, SZ1SMB59xxT3G Series** **==> picture [492 x 614] intentionally omitted <==** **----- Start of picture text -----**<br> 6<br>1K<br>RECTANGULAR<br>5 500 NONREPETITIVE<br>WAVEFORM<br>4 300 T J �=�25°C PRIOR<br>200 TO INITIAL PULSE<br>3 TL<br>100<br>2 50<br>30<br>1<br>20<br>TA<br>0 10<br>0 25 50 75 100 125 150 0.1 0.2 0.3 0.5 1 2 3 5 10 20 30 50 100<br>T, TEMPERATURE (°C) PW, PULSE WIDTH (ms)<br>Figure 1.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
