1N6332US/TR

Overview

The Microchip Technology 1N6332US/TR is a surface-mount Zener voltage regulator with a nominal breakdown voltage of 22V. It operates within a junction temperature range of -65°C to +175°C and features a steady-state power dissipation rating of 0.5W at an end cap temperature of 150°C. The device utilizes a B-SQ MELF package and offers standard 5% voltage tolerance, with tighter 1% and 2% options available in the series.

Feature Summary

• Hermetically sealed voidless glass construction using internal metallurgical bonds for high reliability
• Surface mount equivalent of JEDEC registered 1N6309 through 1N6355 series
• Inherently radiation hard and non-sensitive to electrostatic discharge

Applications

• High-reliability applications where failure cannot be tolerated
• Voltage regulation over broad operating current and temperature ranges
• Military qualified environments requiring MIL-PRF-19500/533 compliance

Procurement Notes

Verify that the specific ordering suffix matches the required voltage tolerance and RoHS compliance status. Confirm the availability of JAN, JANTX, JANTXV, or JANS reliability levels if military qualification is necessary. Ensure the tape and reel packaging aligns with EIA-481-B standards for automated assembly processes.

Selection Notes

Select this component when a robust, hermetically sealed surface-mount Zener diode is required for critical systems. Consider the 0.5W power dissipation limit and thermal resistance values when designing heat management strategies. Evaluate the need for tighter voltage tolerances beyond the standard 5% specification based on circuit precision requirements.

Part Context

This part belongs to the 1N6309US through 1N6355DUS series of 500mW glass Zener diodes. The series provides extensive selections from 2.4V to 200V. It serves as the surface-mount counterpart to traditional axial-leaded packages while maintaining industry-standard electrical characteristics and physical dimensions for direct footprint compatibility.

Replacement Considerations

Direct replacements include other variants within the 1N6309US through 1N6355US series offering different voltage ratings. Cross-reference with JAN, JANTX, JANTXV, and JANS versions for identical electrical performance but varying reliability qualifications.
