1N4496

Single Zener Diodes Overview

The Microchip Technology 1N4496 is a 200 V Zener voltage regulator with a 1.5 W steady-state power dissipation rating at +112 °C lead temperature. It operates within a junction and storage temperature range of -65 °C to +175 °C. The device features a maximum dynamic impedance of 1500 Ω at the test current of 1.2 mA, with a maximum reverse leakage current of 8000 µA at 160 V. It utilizes a DO-41 glass package.

Single Zener Diodes Feature Summary

• Hermetically sealed void-less glass construction with internal metallurgical bonds for robust reliability.
• Triple-layer passivation providing inherent radiation hardness and non-sensitivity to electrostatic discharge.
• Flexible axial-lead mounting terminals suitable for through-hole integration.

Single Zener Diodes Applications

• High-reliability applications where failure cannot be tolerated
• Voltage regulation over broad operating current and temperature ranges
• Military qualified electronic systems

Single Zener Diodes Procurement Notes

Verify the specific qualification level required for your application, as this component is available in JAN, JANTX, JANTXV, and JANS variants per MIL-PRF-19500/406. Confirm whether RoHS compliance is necessary, noting that compliant versions are restricted to commercial grade only. Ensure the ordering suffix matches the desired tolerance and packaging specifications.

Single Zener Diodes Selection Notes

Select this component when a high-voltage Zener regulator with significant power handling is needed. The 200 V breakdown voltage accommodates high-side regulation needs. Consider the thermal resistance and derating curves if ambient temperatures exceed standard conditions. Verify that the 1500 Ω dynamic impedance meets the ripple rejection requirements of the target circuit design.

Single Zener Diodes Part Context
