1N4942-AP

Overview

The MCC 1N4942-AP is a fast recovery rectifier diode rated for 200 V maximum repetitive peak reverse voltage and 1.0 A average forward current. It utilizes a DO-41 axial leaded package with an epoxy molding compound that meets UL 94 V-0 flammability ratings. The device features low leakage current, reaching 5.0 μA at 25°C, and a typical junction capacitance of 15 pF. Electrical characteristics include a maximum instantaneous forward voltage of 1.3 V at 1.0 A and a maximum reverse recovery time of 150 ns.

Feature Summary

• Fast switching capability with low leakage current
• High temperature metallurgically bonded construction
• Hermetically sealed glass passivated cavity-free junction

Applications

• General purpose high efficiency rectification
• Inverter circuits
• Free wheeling diodes
• Polarity protection

Procurement Notes

Verify the specific suffix to confirm packaging type. The -AP suffix indicates Ammo Box packing containing 5,000 pieces per box. Confirm RoHS compliance status and ensure procurement from authorized distributors to guarantee genuine parts with full traceability. Check for halogen-free availability if required by adding the -HF suffix.

Selection Notes

Select this component for applications requiring fast recovery times and low reverse leakage in standard through-hole designs. Ensure the operating ambient temperature remains within the specified range and consider thermal derating curves for sustained currents above 55°C. Verify that the 150 ns reverse recovery time aligns with the circuit's switching frequency requirements.

Part Context

This part belongs to the 1N4942 through 1N4948 series of 1 Amp fast recovery rectifiers manufactured by Micro Commercial Components. The series covers reverse voltage ratings from 200 V to 1000 V, sharing common mechanical dimensions and electrical characteristics such as forward current capacity and package style.

Replacement Considerations

Compatible substitutes include the 1N4942 from other manufacturers offering identical 200 V and 1 A ratings in the DO-41 package. Cross-reference datasheets to verify matching reverse recovery times and forward voltage drops before implementation.
