Overview
The onsemi 1N4935RL is an axial-lead fast-recovery rectifier designed for high-efficiency switching applications. It features a 200 V peak repetitive reverse voltage and supports a 1.0 A average rectified forward current. The device exhibits a typical reverse recovery time of 150 ns, enabling operation at frequencies up to 250 kHz. Electrical characteristics include a maximum instantaneous forward voltage of 1.2 V at 150°C and a non-repetitive peak surge current rating of 30 A. The component operates within a junction temperature range of -65°C to +150°C.
Feature Summary
- Fast recovery performance with a typical 150 ns reverse recovery time suitable for high-frequency circuits
- Glass passivated junction construction providing low leakage current and corrosion resistance
- Metalurgically bonded die attachment ensuring high reliability under thermal stress
Applications
- DC power supplies
- Inverters and converters
- Ultrasonic systems
- Choppers
- Free wheeling diodes
Procurement Notes
Verify the specific ordering suffix to confirm packaging configuration. The 'RL' designation indicates availability in tape and reel format containing 5000 units per reel. Confirm RoHS compliance status and lead finish specifications against the latest manufacturer documentation prior to integration into production workflows.
Selection Notes
Select this component when a 200 V blocking capability is required alongside fast switching speeds. Ensure the application circuit can accommodate the specified 1.0 A continuous current limit and that the thermal management strategy maintains the junction temperature within the rated operating range during peak load conditions.
Part Context
This part belongs to the 1N493x series of axial-lead fast-recovery rectifiers manufactured by onsemi. The series covers voltage ratings from 50 V to 600 V while maintaining a consistent 1.0 A current handling capacity across all variants.
Replacement Considerations
Compatible substitutes within the same series include 1N4933 (50 V), 1N4934 (100 V), 1N4936 (400 V), and 1N4937 (600 V). Verify voltage ratings match the specific circuit requirements before substitution.
