JAN1N5535D-1

Single Zener Diodes Overview

The JAN1N5535D-1 is a low voltage avalanche Zener diode manufactured by Microchip Technology, qualified per MIL-PRF-19500/437. It features a hermetically sealed axial-lead glass DO-35 (DO-204AH) package with an internal metallurgical bond. The device provides a nominal Zener voltage of 15 V at a test current of 1.0 mA, with a tight tolerance of ±1%. Maximum DC Zener current is 25 mA, and steady-state power dissipation is rated at 0.5 W.

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against the datasheet nomenclature to ensure correct voltage tolerance and qualification level. Confirm that the metallurgical bond option is required for JAN, JANTX, or JANTXV qualifications. Check for RoHS compliance status as it varies by grade. Ensure ordering documentation matches the exact part number format including all suffixes.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy within ±1% is required alongside military-grade environmental resilience. The DO-35 package supports flexible axial-lead mounting. Consider the maximum regulator current and power derating curves for thermal management. Verify compatibility with system noise density requirements if used in sensitive analog circuits.
