1N6352

Overview

The Microchip Technology 1N6352 is a military-qualified Zener voltage regulator diode designed for high-reliability applications. It features a hermetically sealed voidless-glass package with internal metallurgical bonds. The device provides a nominal Zener voltage of 150 V at a test current of 0.85 mA, with a maximum dynamic impedance of 1,000 ohms and a maximum reverse leakage current of 114 µA at 150 °C. Rated for 0.5 W steady-state power dissipation, it operates within a junction temperature range of -65 °C to +175 °C.

Feature Summary

• Hermetically sealed voidless hard glass construction with tungsten slugs
• Internal Category 1 metallurgical bonds for enhanced reliability
• Qualified per MIL-PRF-19500/533 standards
• Inherently radiation hard

Applications

• High-reliability aerospace systems
• Military electronic circuits
• Harsh environment voltage regulation
• Radiation-hardened designs

Procurement Notes

Verify the specific ordering suffix (e.g., JAN, JANTXV) to confirm the required reliability level and RoHS compliance status. Commercial versions may differ in termination finish and environmental qualification. Confirm package availability matches design requirements, as axial leaded and surface-mount variants exist within the series. Consult official documentation for derating curves and handling instructions.

Selection Notes

Select this component when a robust, hermetically sealed Zener diode is required for critical voltage reference or protection tasks. Ensure the 150 V nominal rating aligns with circuit breakdown requirements. Consider the thermal resistance characteristics for power dissipation management. Verify that the package style meets the mechanical constraints of the target assembly.
