GLASS ZENER DIODES

DESCRIPTION

APPEARANCE

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. Standard voltage tolerance is +/- 5% with tighter

tolerances available down to 1%. With its glass hermetic qualities, it may

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

control drawing (SCD).

DO-213AB

FEATURES

APPLICATIONS / BENEFITS

•

Electrically similar to the JEDEC registered 1N4728

•

Regulates voltage over a broad operating current

thru 1N4764 zener series

and temperature range

•

Zener voltages available 3.3V to 100V

•

Wide selection from 3.3 to 100 V

Leadless package for surface mounting

Ideal for high density mounting

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