Overview
The onsemi 1N4934RLG is a fast recovery rectifier with a peak repetitive reverse voltage of 100 V and an average rectified forward current of 1.0 A. It features a typical reverse recovery time of 175 ns and a non-repetitive peak surge current rating of 30 A. The device operates within a junction temperature range of -65°C to +150°C, has a maximum instantaneous forward voltage of 1.2 V at 150°C, and utilizes the DO-41 axial lead package.
Feature Summary
- Fast recovery characteristics suitable for high-frequency applications
- Glass passivated junction for enhanced reliability
- Plastic epoxy molded case with UL flammability classification 94V-0
Applications
- DC power supplies
- Inverters and converters
- Ultrasonic systems

Procurement Notes
Verify that the ordering suffix RL indicates tape and reel packaging containing 5000 units per reel. Confirm the presence of the G suffix or microdot marking to ensure the component is Pb-Free. Cross-reference the specific part number against the manufacturer's official datasheet to validate electrical parameters and mechanical dimensions before finalizing procurement specifications.
Selection Notes
Select this component when a 100 V blocking capability is required alongside fast switching performance. Ensure the application does not exceed the 1.0 A continuous forward current limit under resistive load conditions. Verify thermal management requirements against the specified junction-to-ambient thermal resistance for the intended operating environment.
Part Context
This device belongs to the 1N493x series of axial-lead glass passivated fast recovery rectifiers manufactured by onsemi. The series covers voltage ratings from 50 V to 600 V, sharing common mechanical and thermal characteristics while differing in reverse voltage capabilities. The 1N4934 variant specifically targets 100 V applications within this family.
Replacement Considerations
Compatible substitutes include other 1N4934 variants such as 1N4934G or 1N4934RL, provided they meet the same 100 V reverse voltage and 1.0 A current ratings. Verify pinout compatibility and package dimensions (DO-41) to ensure direct replacement feasibility.
