Overview
The 1N4934GHR0G is a fast recovery rectifier from the Taiwan Semiconductor 1N4933G–1N4937G series, rated for a repetitive peak reverse voltage of 100V and an average forward current of 1A. It features a maximum non-repetitive surge forward current of 30A and a junction temperature range of -55°C to +150°C. The device utilizes a DO-204AL (DO-41) package with pure tin-plated leads. Electrical characteristics include a typical forward voltage of 1.2V at 1A, a reverse current of 5µA at 25°C, and a reverse recovery time of 200ns.
Feature Summary
- AEC-Q101 qualified for automotive reliability standards
- High efficiency with low forward voltage drop
- High surge current capability for robust operation
- RoHS compliant and halogen-free construction
Applications
- DC to DC converter circuits
- Switching mode power supplies and inverters
- General purpose rectification tasks
Procurement Notes
Verify that the specific suffix 'H' confirms AEC-Q101 qualification status as defined in the manufacturer's ordering guide. Confirm the packaging type matches the required reel or ammo box quantity specifications. Ensure the component version aligns with the latest datasheet revision I2104 to guarantee accurate thermal and electrical parameter data during integration.
Selection Notes
Select this component when a 100V blocking voltage and 1A continuous current rating are required in a standard axial leaded package. Consider the AEC-Q101 qualification if the application demands automotive-grade reliability. Evaluate the 200ns reverse recovery time against switching frequency requirements to ensure adequate performance in high-efficiency conversion topologies.
Part Context
This part belongs to the 1N493xG series of fast recovery rectifiers manufactured by Taiwan Semiconductor. The series covers voltage ratings from 50V to 600V, sharing identical physical dimensions and general electrical profiles while differing primarily in their peak reverse voltage capabilities. The 'H' suffix specifically denotes AEC-Q101 qualification within this product family.
Replacement Considerations
Cross-reference other manufacturers offering 1N4934 equivalents in the DO-41 package. Verify that substitute parts meet the same 100V VRRM, 1A IF, and 200ns trr specifications. Confirm compatibility with existing PCB footprints and soldering processes.
