1N3036B-1

Single Zener Diodes Overview

The Microchip Technology 1N3036B-1 is a unidirectional voltage regulator diode constructed from silicon. It features a nominal Zener voltage of 36 V with a tolerance of ±5%. The device is rated for a maximum DC power dissipation of 1 watt at a case temperature of +95°C, with a derating factor of 12.5 mW/°C above this threshold. It utilizes a DO-41 axial through-hole package and supports an operating temperature range from -55°C to +175°C.

Single Zener Diodes Feature Summary

• Metallurgically bonded construction for enhanced reliability
• Double plug design suitable for high-reliability applications
• Compliance with MIL-PRF-19500/115 standards

Single Zener Diodes Applications

• Military aerospace systems requiring ruggedized components
• High-reliability industrial control circuits
• Temperature compensated reference voltage sources

Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., JAN, JANTX) against the required military specification grade. Confirm that the axial lead form factor matches the target PCB layout constraints. Ensure thermal management strategies account for the specified power derating curve above 95°C to maintain operational integrity within the extended temperature range.

Single Zener Diodes Selection Notes

Select this component when a robust 36 V regulation point is needed in harsh environments. The DO-41 package offers mechanical stability superior to surface mount alternatives. Consider the higher thermal resistance compared to SMD options when designing heat dissipation paths for continuous operation near maximum ratings.

Single Zener Diodes Part Context

This part belongs to the 1N3036 series of 1-watt Zener diodes manufactured by Microchip. The series includes various voltage ratings ranging from 16 V to 45 V. These devices are designed to meet stringent military performance criteria, offering consistent electrical characteristics across wide temperature variations compared to commercial-grade equivalents.

Single Zener Diodes Replacement Considerations

Equivalent parts include CDI-DIODE CDLL3036B and generic 1N3036B variants. Verify pinout compatibility and ensure the substitute meets the same MIL-PRF-19500/115 qualification level if used in regulated applications.
