- Note 1 Test conditions for zener voltage and impedance are as follows:  IZ is applied 40 ±10ms prior to reading.  Mounting contacts are located 3/8” to 1/2” from the inside edge of mounting clips to the body of the diode (TA = +25°C +8°, –2°C). 

- Note 2 Surge current is specified as the maximum allowable peak, non–recurrent square–wave current with a pulse width, PW, of 8.3ms.  Mounting contact located as specified in Note 1. 

- Note 3 Test conditions for voltage regulation are as follows:  VZ measurements are made at 10% and then at 50% of the IZ max value listed in the “Electrical Characteristic” table.  The test current time duration for each VZ measurement is 40 ±10ms (TA = +25°C +8°, –2°C).  Mounting contact located as specified in Note 1.

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.

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.
