1N4936 TR TIN/LEAD

Overview

The Central Semiconductor Corp 1N4936 TR TIN/LEAD is a silicon fast recovery rectifier diode designed for through-hole mounting in the DO-41 package. It features a peak repetitive reverse voltage of 400 V and a maximum continuous forward current of 1 A. The device exhibits a peak reverse recovery time of 300 ns, making it suitable for high-speed switching applications. It operates within a junction temperature range of -65°C to +150°C and dissipates power up to 1 W.

Feature Summary

• Fast recovery characteristics with a 300 ns reverse recovery time
• High peak repetitive reverse voltage rating of 400 V
• Robust surge current handling capability of 30 A
• Wide operating temperature range extending to +150°C

Applications

• High-frequency rectification circuits
• Free-wheeling diode applications
• General-purpose switching power supplies
• Inverter and chopper circuits

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm lead-free versus tin/lead plating status, as designations may vary by production batch. Confirm RoHS compliance requirements prior to procurement. Ensure the DO-41 through-hole package aligns with the target PCB footprint. Validate that the 400 V reverse voltage rating meets the circuit's peak inverse voltage demands.

Selection Notes

Select this component when a standard fast recovery diode is required for general-purpose applications. The 1 A forward current rating supports moderate load conditions. The 400 V breakdown voltage provides adequate margin for common low-voltage AC lines. Consider thermal management for the DO-41 package if ambient temperatures approach the upper operational limit.

Part Context

This part belongs to the 1N4936 series of silicon planar fast recovery rectifiers manufactured by Central Semiconductor Corp. The series is characterized by high reliability and consistent electrical performance across batches. The DO-41 axial leaded package ensures compatibility with traditional through-hole manufacturing processes and automated insertion equipment.

Replacement Considerations

Direct parameter-equivalent substitutes include the Vishay 1N4936 and onsemi 1N4936RLG. Verify pinout compatibility and package dimensions before substitution. Ensure replacement parts meet the same 300 ns recovery time and 400 V voltage ratings.
