1N6352US/TR

Overview

The Microchip Technology 1N6352US/TR is a surface-mount Zener diode with a nominal breakdown voltage of 150 V and a maximum power dissipation of 0.5 W. It features a B-SQ MELF package, operates within a junction temperature range of -65°C to +175°C, and exhibits a dynamic impedance of 1000 Ohms at the test current IZT. The device provides a reverse leakage current of 50 nA at 114 V and maintains a forward voltage of 1.4 V at 1 A.

Feature Summary

• Hermetically sealed voidless glass construction with internal metallurgical bonds for high reliability.
• Surface mount equivalent of JEDEC registered axial-leaded series in a compact B-SQ MELF package.
• Inherently radiation hard and non-sensitive to electrostatic discharge per MIL-STD-750 method 1020.

Applications

• High-reliability applications where failure cannot be tolerated.
• Voltage regulation over broad operating current and temperature ranges.
• Military qualified circuits requiring JAN, JANTX, JANTXV, or JANS levels.

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm tolerance and compliance status. Confirm that the requested variant matches the required military qualification level and packaging format. Ensure compatibility with existing thermal management designs due to the specified junction-to-end cap thermal resistance values.

Selection Notes

Select this component when a robust surface-mount Zener regulator is required for harsh environments. The B-SQ MELF package offers a smaller footprint compared to traditional axial leads while maintaining hermetic sealing. Consider the 1000 Ohm dynamic impedance and 0.5 W power rating for circuit design constraints.

Part Context

This part belongs to the 1N6309US through 1N6355DUS series of voidless hermetically sealed 500 mW glass Zener diodes. The series is qualified per MIL-PRF-19500/533 and includes selections from 2.4 to 200 volts. It serves as the surface-mount counterpart to the industry-standard axial-leaded 1N63xx series.
