Overview
The onsemi 1N4934RL is an axial-lead fast-recovery rectifier designed for high-efficiency switching applications. It features a peak repetitive reverse voltage of 100 V and supports an average rectified forward current of 1.0 A at 75°C ambient temperature. The device exhibits a typical reverse recovery time ranging from 150 to 200 ns, with a maximum of 300 ns under specified conditions. It operates within a junction temperature range of -65°C to +150°C and withstands a non-repetitive peak surge current of 30 A.
Feature Summary
- Fast recovery characteristics optimized for high-frequency operation up to 250 kHz
- Plastic epoxy molded case with corrosion-resistant external surfaces
- Lead-free construction compliant with environmental standards
Applications
- DC power supplies
- Inverters and converters
- Ultrasonic systems
- Choppers
- Free wheeling diodes
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging configuration. The RL suffix indicates tape and reel shipping containing 5000 units per reel. Confirm that the component meets lead-free requirements if applicable to your assembly process. Ensure compatibility with standard through-hole mounting techniques and verify thermal derating curves for capacitive loads before finalizing procurement specifications.
Selection Notes
Select this component when a 100 V blocking capability is required alongside fast recovery performance. The 1.0 A continuous current rating suits moderate power levels in switching circuits. Consider the 150 to 300 ns reverse recovery time for frequencies approaching 250 kHz. Evaluate thermal resistance of 65°C/W for heat dissipation planning in printed circuit board mounting scenarios.
Part Context
This part belongs to the 1N493x series of axial-lead fast-recovery rectifiers manufactured by onsemi. The series includes variants with different voltage ratings: 1N4933 (50 V), 1N4934 (100 V), 1N4935 (200 V), 1N4936 (400 V), and 1N4937 (600 V). All share identical current and recovery time specifications but differ in their peak repetitive reverse voltage capabilities.
Replacement Considerations
Compatible substitutes include 1N4934G, 1N4934RLG, and generic equivalents meeting DO-41 package dimensions. Verify that replacement parts maintain the 100 V reverse voltage and 1.0 A forward current ratings. Ensure reverse recovery times do not exceed 300 ns to preserve circuit timing integrity.
