JANSL2N5151

Single Bipolar Transistors Overview

The JANSL2N5151 is a radiation-hardened PNP power silicon transistor manufactured by Microchip Technology. It is qualified per MIL-PRF-19500/545 and designed for high reliability in harsh environments. The device features a maximum collector current of 2 A and a collector-emitter breakdown voltage of 80 V. It utilizes a TO-205AD metal can package with three pins. The component supports an operating temperature range up to 200 °C and offers radiation tolerance levels, including the JANSL variant rated for 50K rads (Si).

Single Bipolar Transistors Procurement Notes

Verify the specific radiation hardness level suffix against project requirements, as the family includes variants such as JANSM, JANSD, JANSP, JANSL, JANSR, and JANSF with distinct tolerance ratings. Confirm compliance with MIL-PRF-19500/545 specifications during acquisition. Ensure the procurement documentation explicitly states the device grade and radiation qualification data to meet defense or space application standards.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits that demand high radiation tolerance and significant current handling capabilities. The PNP configuration and 2 A rating suit power management tasks in sensitive environments. Consider the thermal characteristics and metal packaging for heat dissipation needs. Evaluate the specific rad-tolerance tier required by the mission profile before choosing between the available JANSL variants.

Single Bipolar Transistors Part Context

This part belongs to the 2N5151 series of radiation-hardened bipolar junction transistors produced by Microchip Technology. The series encompasses both NPN and PNP types, with various radiation hardness levels denoted by suffixes. The JANSL2N5151 specifically represents the PNP version within the 50K rads (Si) tolerance category, distinguishing it from lower or higher tolerance counterparts in the same product line.

Single Bipolar Transistors Replacement Considerations

Direct replacements include other JANSL2N5151 units from authorized distributors. Cross-referencing with standard 2N5151 devices is not recommended due to the lack of radiation hardening in commercial equivalents. Verify pinout compatibility if substituting with other TO-205AD packaged transistors, though electrical parameters may differ significantly without radiation qualification.
