This surface mountable 1 watt Zener diode series is electrically equivalent to

the 1N4728A thru 1N4764A registration in the DO-41 equivalent package

except that it meets the JEDEC surface mount outline DO-213AB. It is an

ideal selection for applications of high density and low parasitic requirements

for voltage regulation.

tolerances available down to 1%.

also be used for high reliability applications when required by a source

control drawing (SCD).

•

Electrically similar to the JEDEC registered 1N4728

thru 1N4764 zener series

Zener voltages available 3.3V to 100V

Standard voltage tolerances are +/- 5% with “A” suffix

and 10 % with no suffix identification

Tight tolerances available in plus or minus 2% or 1%

with C or D suffix respectively

Options for screening in accordance with MIL-PRF-

19500 for JAN, JANTX, JANTXV, and JANS are

available by adding MQ, MX, MV, or MSP prefixes

respectively to part numbers.

Surface mount equivalents also available as

SMAJ4728A to SMAJ4764A and SMAJ4728A to

SMAJ4764A

Plastic body axial-leaded Zener equivalents are also

available as 1N4728A to 1N4764A
