Available on
commercial
versions
Silicon 500 mW Zener Diodes
Qualified per MIL-PRF-19500/127
DESCRIPTION
This popular series of 500 mW Zener voltage regulators provides a selection from 2.4 to 12
volts in a standard 5% tolerance as well as available tighter 2% and 1% tolerances. These
axial-leaded, glass DO-35 Zeners feature an internal metallurgical bond and are military
qualified to the JAN, JANTX, and JANTXV level. A RoHS compliant commercial grade only
version is also available.
Qualified Levels:
JAN, JANTX, and
JANTXV
Important: For the latest information, visit our website http://www.microsemi.com.
FEATURES
JEDEC registered 1N746 through 1N759A and 1N4370 through 1N4372A series.
Standard voltage tolerance is ± 5% with optional tighter tolerances of ± 2% or 1%.
Internal metallurgical bond.
JAN, JANTX, and JANTXV qualifications are available per MIL-PRF-19500/127.
(See part nomenclature for all available options.)
RoHS compliant versions available (commercial grade only).
APPLICATIONS / BENEFITS
Regulates voltage over a broad range of temperature and current.
Regulated voltage range from 2.4 to 12 V.
Flexible axial-lead mounting terminals.

NOTES:
1. See Figures 1 and 2 for derating curves. TA = +75 °C on an FR4 PC board with 1 oz copper
metalization.
2. The 0.5 W linearly derates starting at TL = 50 °C and goes to zero at 175 °C. For ambient TA
condition on a typical PC board, it linearly derates from 400 mW starting at 55 °C and goes to zero at
175 °C (see Figure 2).
