1N6074US/TR

Overview

The 1N6074US/TR is a single fast recovery rectifier manufactured by Microchip Technology, designed for surface-mount applications. It features a reverse voltage rating of 100 V and a maximum forward current of 9.4 A. The device exhibits a low forward voltage drop of 2.04 V and a rapid recovery time of 30 ns. It operates within a temperature range of -65°C to +155°C and is housed in an A-Package-2 (DO-204AD) SMD package. The unit supports a peak surge current of 35 A with a maximum reverse leakage current of 1 µA.

Feature Summary

• Fast recovery performance with 30 ns switching speed suitable for high-frequency circuits
• Hermetically sealed voidless glass construction ensuring reliability in harsh environments
• High thermal stability operating up to +155°C junction temperature
• Robust surge handling capability with 35 A peak forward non-repetitive current

Applications

• High-speed switching power supplies
• Freewheeling diodes in inductive load circuits
• Reverse polarity protection in automotive systems
• DC-DC converter output rectification

Procurement Notes

Verify the specific suffix TR indicates reel packaging when ordering. Confirm the A-Package-2 footprint matches your PCB design constraints. Ensure the 100 V reverse voltage rating meets your circuit's peak inverse voltage requirements. Check for RoHS compliance status if required by your manufacturing standards. Validate the 9.4 A continuous current rating against your thermal management plan.

Selection Notes

Select this component when a fast recovery rectifier is needed for 100 V applications requiring surface-mount integration. The 30 ns recovery time makes it suitable for higher frequency operations compared to standard rectifiers. Consider the 1.5 W power dissipation limit and ensure adequate heatsinking or copper area for thermal regulation. Compare against similar DO-204AD packages from other manufacturers if supply chain diversity is required.

Part Context

This part belongs to Microchip's family of military-qualified and commercial surface-mount Zener and rectifier diodes. The US suffix typically denotes a specific surface-mount variant compatible with automated assembly processes. These components are often used in aerospace, defense, and industrial equipment where long-term reliability and environmental resilience are critical specifications.

Replacement Considerations

Direct substitutes include other 100V 9.4A fast recovery rectifiers in the DO-204AD (SMA/DO-214AC equivalent depending on pinout) package. Verify that replacement parts match the 30 ns recovery time and 2.04 V forward voltage characteristics. Ensure the alternative device supports the same -65°C to +155°C operating temperature range.
