1N4942GP-TP

Overview

The MCC 1N4942GP-TP is a glass passivated junction rectifier diode housed in the DO-41 axial leaded package. It features a maximum repetitive reverse voltage of 200V and an average forward current rating of 1.0A at 55°C ambient temperature. The device exhibits a low leakage current of 20µA at 150°C and a peak forward surge current capability of 30A for an 8.3ms half-sine wave pulse. Electrical characteristics include a maximum instantaneous forward voltage of 1.3V at 1.0A and a typical reverse recovery time of 250ns.

Feature Summary

• Glass passivated junction construction designed to withstand high mechanical and thermal stress during circuit mounting.
• Low leakage current and fast switching performance suitable for general-purpose rectification applications.
• Epoxy casing meets UL 94 V-0 flammability ratings for enhanced safety compliance.

Applications

• General purpose rectification in power supply circuits
• Free-wheeling diodes in inductive load protection
• Polarity protection in electronic assemblies

Procurement Notes

Verify that the ordering suffix matches the required packaging format, as the standard TP designation indicates bulk packing. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, noting that specific halogen-free variants require the additional HF suffix. Ensure procurement channels are authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when a 200V blocking voltage and 1A continuous current capacity are required within a standard DO-41 footprint. Consider the 250ns reverse recovery time for switching speeds appropriate for general-purpose applications rather than high-frequency converters. Evaluate thermal derating requirements based on the specified 50°C/W junction-to-ambient thermal resistance.

Part Context

This part belongs to the 1N4942GP through 1N4948GP series manufactured by Micro Commercial Components. The series utilizes a standardized DO-41 axial package across multiple reverse voltage ratings ranging from 200V to 1000V. The GP suffix denotes the glass passivated junction technology common to this product line.

Replacement Considerations

Cross-reference with other manufacturers' 1N4942 equivalents ensuring identical DO-41 package dimensions and matching electrical parameters for 200V reverse voltage and 1A forward current ratings.

FAQ

What is the maximum operating junction temperature?

The maximum operating junction temperature is 150°C.

How does the suffix affect the component?

The TP suffix designates the standard bulk packaging format. Adding an HF suffix indicates a halogen-free version of the component.
