JANSR2N5154

Single Bipolar Transistors Overview

The JANSR2N5154 is a radiation-hardened NPN power silicon transistor manufactured by Microchip Technology. It belongs to the JANS family, qualified per MIL-PRF-19500/544 for high-reliability applications. The device is a registered equivalent of the JEDEC 2N5154 standard. It utilizes an SMD-0.5 (U3) package configuration. Key electrical characteristics include a collector-emitter voltage rating of 80V and a maximum DC collector current of 2A. The component is designed for operation in extreme environments, featuring a wide temperature range from -65°C to +200°C junction temperature.

Single Bipolar Transistors Feature Summary

• Radiation Hardness Assurance (RHA) qualified to JANSF level for high-reliability military and aerospace use.
• Registered as a direct equivalent to the JEDEC 2N5154 standard specification.
• Utilizes a hermetic SMD-0.5 (U3) surface-mount package for robust physical integration.

Single Bipolar Transistors Applications

• High-reliability spaceborne electronic systems
• Military avionics power control circuits
• Radiation-tolerant amplifier stages

Single Bipolar Transistors Procurement Notes

Verify that the specific suffix RHA qualification matches the required mission profile. Confirm the SMD-0.5 package compatibility with the target PCB footprint. Ensure handling procedures adhere to ESD and moisture sensitivity guidelines for hermetic ceramic packages. Cross-reference the latest PCN documents for any manufacturing site changes.

Single Bipolar Transistors Selection Notes

Select this component when radiation tolerance is mandatory for NPN power switching or amplification. Compare against JANSM variants if leaded TO-5 packaging is preferred over surface mount. Verify thermal management requirements align with the 1W power dissipation limit in the intended enclosure environment.

Single Bipolar Transistors Part Context

This part is part of the JANS series of radiation-hardened bipolar transistors produced by Microchip/Microsemi. It serves as the surface-mount version of the traditional through-hole 2N5154, providing identical electrical performance with enhanced resistance to ionizing radiation effects common in orbital environments.

Single Bipolar Transistors Replacement Considerations

JANSM2N5154U3: Same JANS qualification but verify package pinout compatibility. JANSD2N5154: Different sub-grade within the same family; verify specific reliability requirements.
