JANSF2N5151

Single Bipolar Transistors Overview

The JANSF2N5151 is a radiation-hardened PNP power silicon transistor manufactured by Microchip Technology. It is qualified per MIL-PRF-19500/545 and belongs to the JANSL2N5151 family, offering high total ionizing dose tolerance of 300K rads (Si). The device features a maximum collector current of 2A and a collector-emitter breakdown voltage of 80V. It utilizes a metal TO-205AD (TO-39) package with three pins, supporting an operating temperature range up to 200°C.

Single Bipolar Transistors Feature Summary

• Radiation hardened to withstand 300K rads (Si) total ionizing dose
• Qualified to MIL-PRF-19500/545 military standards
• High thermal stability with operation up to 200°C

Single Bipolar Transistors Applications

• Spacecraft avionics systems
• Satellite communication circuits
• High-reliability military electronics

Single Bipolar Transistors Procurement Notes

Verify the specific radiation hardness level against project requirements, as the JANSL series includes variants from 3K to 300K rads. Confirm that the TO-205AD metal package meets mechanical constraints. Ensure compliance with MIL-PRF-19500/545 qualification standards for defense applications. Check for RoHS non-compliance status if environmental regulations apply.

Single Bipolar Transistors Selection Notes

Select this component for environments requiring extreme radiation tolerance. Compare with lower-radiation-hardened variants like JANSM or JANSD if cost is a primary driver and radiation levels are lower. Ensure the 80V V(BR)CEO rating exceeds circuit peak voltages. Verify that the 2A I(C) limit accommodates load currents without exceeding thermal dissipation limits in the TO-39 package.

Single Bipolar Transistors Part Context

This part is a member of the Microchip JANSL2N5151 radiation-hardened transistor family. It shares the same electrical baseline as other variants but differs in radiation tolerance levels ranging from 3K to 300K rads (Si). It serves as a robust replacement for standard commercial transistors in harsh space and nuclear environments.

Single Bipolar Transistors Replacement Considerations

Direct substitutes within the same radiation tolerance class include other 300K rads (Si) qualified PNP transistors from the JANSL series. Cross-reference MIL-PRF-19500/545 specifications for equivalent performance.
