Overview
The Microchip Technology 1N6341 is a military-qualified Zener voltage regulator diode from the 1N6309 through 1N6355 series. It features a 51V nominal Zener voltage with standard 5% tolerance and operates at a maximum steady-state power dissipation of 0.5W. The device utilizes a voidless hermetically sealed glass package in a DO-35 axial lead configuration, ensuring robust construction for high-reliability applications.
Feature Summary
- Hermetically sealed voidless hard glass package with tungsten slugs
- Internal metallurgical bonds for enhanced structural integrity
- Qualified per MIL-PRF-19500/533 for military reliability levels
- Inherently radiation hard design
Applications
- High-reliability circuits where failure cannot be tolerated
- Voltage regulation over broad operating current and temperature ranges
- Radiation-hardened electronic systems
Procurement Notes
Verify the specific reliability level (JAN, JANTX, JANTXV, or JANS) required for your application, as these suffixes denote different qualification standards under MIL-PRF-19500/533. Confirm terminal finish availability, noting that RoHS compliant matte/tin options are restricted to commercial grade versions only. Ensure the ordering nomenclature matches the desired voltage tolerance specification.
Selection Notes
Select this component for applications requiring a 51V reference with standard 5% tolerance. For tighter tolerances, consider variants with 'C' (2%) or 'D' (1%) suffixes. Evaluate thermal derating requirements based on the junction-to-lead resistance, which varies between 150 oC/W for lower voltage models and 95.5 oC/W for higher voltage models like the 1N6341.
Part Context
The 1N6341 belongs to the industry-recognized 1N6309 through 1N6355 series of 0.5W Zener voltage regulators. This family offers an extensive selection of voltages ranging from 2.4V to 200V. The series is available in both axial-lead DO-35 packages and surface-mount MELF configurations, providing flexibility for various mounting styles while maintaining consistent hermetic sealing standards.
Replacement Considerations
Direct substitutes include other manufacturers' JEDEC registered 1N6341 equivalents. Verify that replacement parts meet the same MIL-PRF-19500/533 qualification levels if military reliability is required. Surface-mount alternatives exist within the same series, such as the 1N6341US in the B-SQ MELF package.
