469-01

Bridge Rectifier Overview

The Microchip Technology 469-01 is a single-phase bridge rectifier qualified per MIL-PRF-19500/469. It features an aluminum case with electrically isolated terminals and voidless hermetically sealed glass encapsulation for each leg. The device supports a maximum average DC output current of 10 A at a case temperature of +55 °C, derating to 6 A at +100 °C. It has a working peak reverse voltage rating of 200 V per leg, a junction-to-case thermal resistance of 5 °C/W, and operates within a temperature range of -65 °C to +150 °C.

Bridge Rectifier Feature Summary

• Hermetically sealed construction using voidless glass encapsulation and internal metallurgical bonds for high reliability
• Electrically isolated aluminum case design suitable for direct mounting to heat sinks
• Qualified to JANTX and JANTXV levels under MIL-PRF-19500/469 specifications

Bridge Rectifier Applications

• Military and aerospace power supply systems requiring high reliability
• High-reliability industrial equipment where failure cannot be tolerated
• Radiation-hardened electronic applications

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix to confirm the required reliability level and compliance status. The base part number indicates the electrical characteristics, while suffixes such as 'JANTX' or 'e3' define the qualification grade and solder finish. Confirm that the procurement documentation matches the intended environmental operating conditions and mechanical mounting requirements before finalizing orders.

Bridge Rectifier Selection Notes

Select this component when a hermetically sealed, radiation-tolerant bridge rectifier is required for critical systems. Ensure the thermal management design accounts for the 5 °C/W junction-to-case resistance to maintain operation within the specified temperature limits. Verify that the system's peak reverse voltage does not exceed the 200 V rating per leg and that surge current capabilities align with the application's inrush requirements.

Bridge Rectifier Part Context

This component belongs to the 469-01 through 469-05 series of high-current single-phase bridge rectifiers. The series shares identical physical dimensions and thermal characteristics, differing only in the working peak reverse voltage rating per leg. These devices are designed for military-grade environments and utilize the same robust construction techniques across all voltage variants.

Bridge Rectifier Replacement Considerations

Direct replacements include other parts qualified to MIL-PRF-19500/469 with matching 200 V ratings. Verify that substitute components maintain the same hermetic sealing, package dimensions, and thermal resistance values to ensure compatibility with existing mounting and cooling infrastructure.
