Overview
The 1N4933G-K is a fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a single silicon element housed in a DO-41 axial leaded package. The device supports a maximum average forward rectified current of 1A and a repetitive peak reverse voltage of 50V. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 50V, a forward voltage drop of 1.2V at 1A, and a reverse recovery time of 200 ns. The junction temperature range extends from -55°C to 150°C.
Feature Summary
- Fast recovery performance for high efficiency applications
- High current capability with 1A average rectified output
- Plastic package with UL flammability classification 94V-O
Applications
- General purpose rectification in power supplies
- Free wheeling diode circuits
- High frequency switching applications
Procurement Notes
Verify the specific suffix 'K' against the manufacturer's official datasheet to confirm packaging details and compliance status. Ensure the component meets RoHS requirements for your target market. Confirm availability directly with Taiwan Semiconductor or authorized distributors as stock levels fluctuate.
Selection Notes
Select this component when a standard 1A, 50V fast recovery rectifier is required in an axial package. Compare the 200 ns reverse recovery time against circuit switching speeds. Verify that the DO-41 footprint matches the PCB design constraints and thermal management needs.
Part Context
This part belongs to the 1N493x series of fast recovery rectifiers. It shares the same electrical specifications as other manufacturers' 1N4933 variants but utilizes Taiwan Semiconductor's specific manufacturing processes and packaging standards. The 'G' typically indicates lead-free composition, while 'K' denotes reel packaging.
Replacement Considerations
Verified equivalent part numbers include 1N4933GP-TP (Micro Commercial Components) and PG4933_R2_00001 (Panjit International Inc.). These parts share identical electrical ratings and mechanical form factors.
