1N4937RLG

Overview

The onsemi 1N4937RLG is a fast recovery rectifier diode with a peak repetitive reverse voltage of 600 V and an average forward current rating of 1.0 A. It utilizes an axial-lead DO-41 package (Case 59-10) and features a typical reverse recovery time of 150 ns, supporting frequencies up to 250 kHz. The device operates within a junction temperature range of -65°C to +150°C and includes a thermal resistance of 65°C/W.

Feature Summary

Fast recovery characteristics suitable for high-frequency switching applications
Glass passivated junction for enhanced stability
Axial lead configuration for through-hole mounting

Applications

DC power supplies
Inverters and converters
Ultrasonic systems
Choppers
Free wheeling diodes

Procurement Notes

Verify the specific ordering suffix 'RLG' confirms tape and reel packaging containing 5,000 units per reel. Confirm the presence of the Pb-Free indicator or microdot marking as specified in the datasheet documentation. Ensure the component matches the Case 59-10 mechanical outline dimensions for proper board integration.

Selection Notes

Select this component when a 600 V blocking capability and 1.0 A continuous current are required. The 150 ns reverse recovery time makes it appropriate for circuits operating at frequencies up to 250 kHz. Consider the axial lead form factor for manual assembly or specific mechanical constraints requiring through-hole technology.

Part Context

This part belongs to the 1N493x series of axial-lead glass passivated fast recovery rectifiers manufactured by onsemi. The series includes variants with different voltage ratings ranging from 50 V to 600 V. The 'RLG' designation specifically indicates the tape and reel packaging format for automated processing.

Replacement Considerations

Compatible substitutes include other 1N4937 equivalents from manufacturers such as Vishay or Sensitron, provided they meet the 600 V reverse voltage and 1.0 A current specifications. Verify that replacement parts maintain similar reverse recovery times and package dimensions.
