500 mW Metallurgically Bonded
Glass Zener Diodes
Qualified per MIL-PRF-19500/435
DESCRIPTION
The 1N4099-1 through 1N4135-1 and 1N4614-1 through 1N4627-1 series are 500 mW, Zener
voltage regulators in the axial-leaded, glass DO-35 package. Voltages from 1.8 to 100V in
5%, 2%, and 1% tolerances are available. They are constructed with an internal metallurgical
bond and are mil-qualified up to the JANS level for high reliability applications.
Qualified Levels:
JAN, JANTX,
JANTXV and JANS
Important: For the latest information, visit our website http://www.microsemi.com.

Notes: 1. When mounted on FR4 PC board (1 oz Cu) with 4 mm2 copper pads and track width 1 mm, length 25
mm.
2. The 0.5 W should be linearly derated 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 500 mW starting at 25 °C and goes to zero at
175 °C (see Figure 2).

SYMBOLS & DEFINITIONS
Definition
Temperature Coefficient of Regulator Voltage: The change in regulator voltage divided by the change in temperature
that caused it expressed in %/C or mV/°C.
Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature.
Regulator Current: The dc regulator current (IZ), at a specified test point (IZT), near breakdown knee (IZK).
Maximum Regulator (Zener) Current: The maximum rated dc current for the specified power rating.
Noise Density: The noise generated over a specified frequency bandwidth usually specified in terms of mV/ √Hz.
Reverse Voltage: The reverse voltage dc value, no alternating component.
Zener Voltage: The Zener voltage the device will exhibit at a specified current (IZ) in its breakdown region.
Dynamic Impedance: The small signal impedance of the diode when biased to operate in its breakdown region at a
specified rms current modulation (typically 10% of IZT or IZK) and superimposed on IZT or IZK respectively.
