JAN1N4942

Single Diodes Overview

The JAN1N4942 is a fast recovery rectifier manufactured by Microchip Technology, designed for through-hole mounting in an axial package. It features a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 1 A. The device exhibits a typical reverse recovery time of 150 ns and a maximum forward voltage of 1.3 V at 1 A. Reverse leakage current is limited to 1 µA at 200 V. It operates within a junction temperature range of -65°C to +175°C and complies with MIL-PRF-19500/359 standards.

• Harsh environment industrial electronics

Single Diodes Procurement Notes

Verify the specific manufacturer lot and date code upon receipt to ensure compliance with project requirements. Confirm that the component meets the MIL-PRF-19500/359 specification as indicated in the datasheet. Check for any physical damage to the axial leads or hermetic seal before installation. Ensure storage conditions align with the moisture sensitivity level defined in the product documentation.

Single Diodes Selection Notes

Select this component when a hermetically sealed, military-qualified fast recovery diode is required for 200 V applications. It is appropriate for designs needing low reverse leakage and high thermal stability up to 175°C. Consider the axial leaded package constraints for PCB layout. Evaluate if the 150 ns recovery time meets the specific switching frequency demands of the circuit design.

Single Diodes Part Context

This part belongs to the JAN series of semiconductor devices produced by Microchip Technology, formerly Microsemi. The JAN prefix denotes parts qualified to military standards. It is distinct from commercial variants like the standard 1N4942, offering higher reliability and environmental resistance. The series includes various voltage ratings within the same package family.

Single Diodes Replacement Considerations

Direct substitutes include other JAN-qualified 200 V fast recovery rectifiers meeting MIL-PRF-19500/359. Verify pinout compatibility and electrical parameters such as reverse recovery time and forward voltage drop. Commercial equivalents may lack the hermetic seal and military qualification required for this specific application.
