1N4934-TP

Overview

The MCC 1N4934-TP is a single-element silicon fast recovery rectifier housed in the DO-41 axial leaded package. It supports an average forward current of 1.0A and withstands a maximum repetitive peak reverse voltage of 100V. Key electrical characteristics include a maximum instantaneous forward voltage of 1.3V at 1.0A, a maximum DC reverse current of 5.0μA at rated voltage, and a typical junction capacitance of 15pF. The device features a maximum reverse recovery time of 200ns and operates within a temperature range of -55°C to +150°C.

Feature Summary

• Fast switching capability with low leakage current
• Epoxy casing meets UL 94 V-0 flammability rating
• Lead-free finish compliant with RoHS standards

Applications

• High frequency rectification circuits
• Free wheeling diode applications
• General purpose rectification

Procurement Notes

Verify the specific ordering suffix when purchasing. The standard -TP designation indicates tape and reel packaging containing 5,000 pieces per reel. Adding the -HF suffix denotes a halogen-free variant. Confirm that the component source is authorized to ensure genuine parts with full traceability and compliance with quality standards.

Selection Notes

Select this component for designs requiring a 100V blocking voltage and 1A continuous current handling in an axial through-hole package. Ensure the application environment stays within the specified operating temperature limits. Consider the 200ns reverse recovery time for high-speed switching requirements and verify thermal management needs against the 30°C/W junction-to-lead thermal resistance.

Part Context

This part belongs to the 1N4933 through 1N4937 series of 1 Amp Fast Recovery Rectifiers manufactured by Micro Commercial Components. All devices in this series share identical physical dimensions, packaging, and general electrical performance profiles, differing primarily in their maximum repetitive peak reverse voltage ratings which range from 50V to 600V.

Replacement Considerations

Cross-reference with other manufacturers' 1N4934 equivalents or MCC's 1N4934GP-TP variant. Verify that substitute components match the DO-41 package outline and meet the same 100V reverse voltage and 1A forward current specifications.

FAQ

What is the maximum reverse recovery time for the 1N4934-TP?

The maximum reverse recovery time is 200ns, measured under conditions of IF=1.0A and VR=30V.

Does the 1N4934-TP come in a halogen-free version?

Yes, a halogen-free version is available by adding the -HF suffix to the part number, resulting in 1N4934-TP-HF.
