Overview
The 1N4934G-K is a silicon rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a single element configuration with a maximum average forward rectified current of 1.0 A and a repetitive peak reverse voltage of 100 V. The device utilizes a DO-204AL (DO-41) plastic axial leaded package. Electrical characteristics include a maximum DC blocking voltage of 100 V, a forward voltage drop of 1.1 V at 1.0 A, and a low leakage current of 5.0 µA at rated voltage. Operating temperatures range from -65 °C to +175 °C junction temperature.
Feature Summary
- Fast recovery performance for efficient switching applications
- Low forward voltage drop to minimize power loss
- High surge current capability for robust operation
- Molded plastic case with UL94V-0 flame retardant epoxy
Applications
- General purpose rectification in power supplies
- Free-wheeling diodes in inductive load circuits
- Polarity protection in electronic systems
Procurement Notes
Verify the manufacturer marking on the component body matches Taiwan Semiconductor Corporation specifications. Confirm the DO-204AL package dimensions and lead finish compatibility with your assembly process. Ensure the part number suffix corresponds to the specific tape and reel or bulk packaging requirements for your production line.
Selection Notes
Select this component when a 100 V reverse voltage rating and 1.0 A continuous current capacity are required. The fast recovery characteristic makes it suitable for higher frequency switching applications compared to standard general-purpose diodes. Consider the thermal management requirements given the 175 °C maximum junction temperature rating.
Part Context
This component belongs to the 1N493x series of fast recovery rectifiers. These devices are widely used in consumer electronics and industrial equipment where reliable rectification is needed. The 'K' suffix typically denotes specific packaging or lot traceability details defined by the manufacturer.
Replacement Considerations
Direct replacements include other manufacturers' 1N4934 variants such as Vishay 1N4934 or ON Semiconductor 1N4934. Verify that substitute parts meet the same 100 V reverse voltage and 1.0 A forward current ratings.
