JANSD2N5152L

Single Bipolar Transistors Overview

The JANSD2N5152L is a radiation-hardened NPN power bipolar junction transistor manufactured by Microchip Technology. It features an 80V collector-emitter voltage rating and a 2A continuous collector current capability, with a maximum power dissipation of 1W. The device utilizes a low-profile ceramic surface-mount package designed for through-hole compatibility or direct board mounting in space-constrained applications. It is qualified to MIL-PRF-19500 standards and offers enhanced total ionizing dose tolerance compared to standard commercial variants.

Single Bipolar Transistors Feature Summary

• Radiation hardening providing immunity to total ionizing dose effects suitable for aerospace environments
• Low-profile ceramic construction ensuring hermetic sealing and thermal stability
• Surface-mount form factor optimized for high-reliability circuit board integration

Single Bipolar Transistors Applications

• Spacecraft power management systems
• Military communication equipment amplifiers
• High-reliability switching circuits in harsh environments

Single Bipolar Transistors Procurement Notes

Verify the specific radiation hardness level (JANSD denotes 10K rads(Si)) against mission requirements. Confirm package orientation and pinout compatibility with existing PCB footprints. Ensure supply chain authorization aligns with defense procurement regulations. Check for recent Product Change Notifications regarding material or process updates that may affect qualification status.

Single Bipolar Transistors Selection Notes

Select this component when radiation tolerance is critical and a low-profile SMT package is required. Compare against JANSL variants if higher radiation hardness is needed, or JANTX variants if cost is a primary driver and radiation exposure is minimal. Ensure thermal management strategies account for the 1W dissipation limit in the chosen enclosure.

Single Bipolar Transistors Part Context

This part belongs to the JANSD series of radiation-hardened silicon transistors from Microchip. It shares electrical characteristics with the through-hole JANSL2N5152L but differs in physical packaging. The series is designed to replace standard military-grade components in satellite and avionics applications where single-event effects and total dose degradation are significant failure modes.

Single Bipolar Transistors Replacement Considerations

Direct functional replacements include the JANSL2N5152L for through-hole designs or the JANTX2N5152U3 for non-radiation-hardened SMT applications. Verify pinout compatibility before substitution. Higher radiation tolerance options such as JANSP or JANSL series parts may be selected if environmental conditions exceed 10K rads(Si) limits.
