BYT30P-400

Overview

The BYT30P-400 is a fast recovery rectifier diode manufactured by STMicroelectronics, designed for high-speed switching applications. It features a repetitive peak reverse voltage of 400 V and an average forward current rating of 30 A at a case temperature of 100°C. The device exhibits a very low reverse recovery time of 50 ns typ and a maximum junction-to-case thermal resistance of 1 °C/W. Operating within a temperature range of -40 to +150°C, it utilizes SOD93 plastic packaging with conduction cooling.

Feature Summary

• Very low reverse recovery time for reduced switching losses
• Low noise turn-off switching characteristics
• High thermal stability with low junction-to-case thermal resistance

Applications

• Free wheeling diode in converters
• Motor control circuits
• Rectifier in switch mode power supplies (SMPS)

Procurement Notes

Verify component authenticity through authorized channels as the BYT30P-400 is listed as obsolete. Confirm package integrity and marking accuracy against the SOD93 mechanical data specifications. Ensure replacement strategies account for the discontinued status when sourcing new production units.

Selection Notes

Select this component for designs requiring fast recovery characteristics and low reverse leakage current. Evaluate thermal management requirements based on the 1 °C/W junction-to-case resistance. Consider the 30 A average forward current limit under specified case temperatures for circuit sizing.

Part Context
