Overview
The Microchip Technology 1N6337 is a military-qualified Zener voltage regulator with a nominal breakdown voltage of 36.0 V at a test current of 3.4 mA. It features a standard 5% tolerance and operates within a junction temperature range of -65 °C to +175 °C. The device dissipates up to 0.5 W steady-state power, exhibits a dynamic impedance of 50 ohms at the test point, and maintains a maximum reverse leakage current of 10 µA at 25 °C.
Feature Summary
- Hermetically sealed voidless glass construction with internal metallurgical bonds for high reliability
- Qualified per MIL-PRF-19500/533 across JAN, JANTX, JANTXV, and JANS levels
- Inherently radiation hard and non-sensitive to electrostatic discharge
Applications
- High-reliability aerospace and defense systems
- Military-grade voltage regulation circuits
- Harsh environment electronics requiring robust construction
Procurement Notes
Verify the specific ordering suffix (e.g., US/TR for surface mount tape-and-reel) against the required package type and reel specifications. Confirm that the selected reliability level matches the project's qualification requirements. Ensure compliance with material declarations and environmental directives relevant to the intended deployment region.
Selection Notes
Select this component when a precise 36 V reference is needed in a ruggedized form factor. Consider the DO-35 axial lead or B-SQ MELF surface-mount packages based on board layout constraints. Evaluate thermal derating curves if operating near the upper temperature limits to ensure stable performance under varying load conditions.
Part Context
This part belongs to the 1N6309 through 1N6355D series of industry-recognized 0.5 W Zener diodes. The series provides extensive voltage selections from 2.4 V to 200 V with various tolerance options. It serves as a surface-mount equivalent to the JEDEC registered 1N6309 through 1N6355 series while maintaining hermetic sealing standards.
Replacement Considerations
Direct substitutes include other manufacturers' 1N6337 variants meeting MIL-PRF-19500/533 specifications. Surface-mount equivalents are available in the 1N6337US series. Verify pinout compatibility and thermal resistance characteristics before substituting.
