Overview
The onsemi 1N4935RLG is a fast recovery rectifier with a 200 V peak repetitive reverse voltage and a 1.0 A average rectified forward current rating. It features a typical reverse recovery time of 150 ns, enabling high efficiency at frequencies up to 250 kHz. The device operates within a junction temperature range of -65°C to +150°C and has a maximum non-repetitive peak surge current of 30 A. It utilizes an axial-lead DO-41 package (Case 59-10) and is supplied in tape and reel format.
Feature Summary
- Fast recovery characteristics optimized for high-frequency applications
- Glass-passivated axial-lead construction for corrosion resistance
- Lead-free manufacturing compliant with environmental standards
Applications
- DC power supplies
- Inverters and converters
- Ultrasonic systems
- Choppers
- Free wheeling diodes
Procurement Notes
Verify the specific ordering suffix 'RLG' confirms the tape and reel packaging configuration containing 5,000 units per reel. Confirm that the component meets Pb-Free requirements as indicated by the 'G' suffix or '/C0071' marking. Ensure the procurement specifications align with the standard axial lead dimensions and polarity band orientation defined in the mechanical case outline.
Selection Notes
Select this component when a 200 V blocking capability is required alongside fast switching speeds. The 150 ns reverse recovery time distinguishes it from standard rectifiers, making it suitable for higher frequency circuits. Verify that the thermal resistance of 65°C/W is adequate for the intended ambient temperature conditions and load derating requirements.
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 1N4935 specifically provides the 200 V rating within this lineup, sharing identical current and recovery time specifications with its siblings.
Replacement Considerations
Compatible substitutes include other 1N4935 variants such as 1N4935RL or 1N4935G, which share the same electrical parameters but differ in packaging format.
