Overview
The Microchip Technology 1N6336 is a military-qualified Zener voltage regulator diode designed for high-reliability applications. It features a 33 V nominal Zener voltage with a standard 5% tolerance, tested at 3.8 mA. The device operates within a -65 °C to +175 °C temperature range and dissipates up to 0.5 W of power. It utilizes a voidless hermetically sealed glass package with axial leads (DO-35) or surface-mount MELF options.
Feature Summary
- Hermetically sealed voidless-glass construction with internal metallurgical bonds
- Qualified per MIL-PRF-19500/533 for JAN, JANTX, JANTXV, and JANS reliability levels
- Inherently radiation hard and non-sensitive to ESD per MIL-STD-750 method 1020
Applications
- High-reliability aerospace systems
- Military defense electronics
- Critical space-grade voltage regulation
Procurement Notes
Verify the specific reliability level suffix (JAN, JANTX, JANTXV, or JANS) required for your mission profile. Confirm RoHS compliance status, as it applies only to commercial grade versions. Ensure the package type matches your assembly requirements, as both axial lead and surface mount variants exist within this series.
Selection Notes
Select based on required voltage tolerance; tighter 1% and 2% options are available via part nomenclature codes. Consider thermal derating curves when designing for ambient temperatures above 55 °C. Verify that the maximum reverse current specifications meet leakage constraints in your circuit design.
Part Context
This component belongs to the 1N6309 through 1N6355D series of 0.5 W Zener diodes. The series covers a wide voltage range from 2.4 V to 200 V. It is manufactured by Microchip Technology, formerly Microsemi, which specializes in ruggedized semiconductor solutions for demanding environments.
Replacement Considerations
Direct substitutes include other 1N6336 variants with different reliability suffixes such as JANTX1N6336US/TR or JANS1N6336US/TR. Commercial equivalents may lack the hermetic sealing and radiation hardness required for qualified applications.
