1N4934GP

Overview

The onsemi 1N4934GP is a single-element silicon rectifier diode housed in the DO-41 plastic axial leaded package. It features a maximum repetitive peak reverse voltage of 100 V and an average forward rectified current rating of 1 A. The device exhibits a low leakage current of 5 uA at rated voltage and a fast recovery time of 75 ns, making it suitable for general-purpose rectification applications requiring reliable performance under standard operating conditions.

Feature Summary

• Fast recovery characteristics enable efficient operation in high-frequency switching circuits
• Low leakage current ensures minimal power loss during reverse bias states
• Robust construction with UL flammability classification for enhanced safety compliance

Applications

• General-purpose rectification in AC to DC conversion circuits
• Freewheeling diodes in inductive load protection networks
• Clamping diodes in signal processing and logic interface stages

Procurement Notes

Verify the specific suffix 'GP' against the manufacturer's official datasheet to confirm exact electrical tolerances and marking codes. Ensure the component meets RoHS environmental standards if required by your assembly process. Cross-reference the DO-41 package dimensions with your PCB footprint library to guarantee mechanical compatibility before finalizing procurement orders.

Selection Notes

Select this component when a 100 V reverse voltage rating and 1 A continuous current capacity are sufficient for the circuit design. Consider its 75 ns recovery time for applications where moderate switching speeds are acceptable without excessive heat generation. Evaluate thermal management requirements based on the expected forward voltage drop and ambient operating temperature range.

Part Context

This part belongs to the 1N493x series of fast recovery rectifiers, which covers a voltage range from 50 V to 600 V while maintaining a consistent 1 A current rating. The series is widely used in consumer electronics and industrial power supplies due to its cost-effectiveness and standardized DO-41 packaging. The GP suffix typically denotes specific manufacturing lot or quality grading variations within the standard product line.

Replacement Considerations

Direct substitutes include the 1N4934 from other manufacturers such as Rectron or Littelfuse, provided they adhere to the same DO-41 package and electrical specifications. Verify that alternative sources maintain the same 75 ns recovery time and 100 V blocking capability to ensure circuit compatibility.
