JANTX2N2222AUB

Single Bipolar Transistors Overview

The JANTX2N2222AUB is a radiation-hardened NPN silicon small-signal switching transistor manufactured by Microchip Technology. It utilizes a hermetically sealed UB-3 ceramic surface-mount package designed for high reliability in harsh environments. The device meets MIL-PRF-19500/255 specifications with JANTX screening levels. Key electrical ratings include a collector-emitter voltage of 50 V, a collector-base voltage of 75 V, and an emitter-base voltage of 6 V. It supports a continuous collector current of 800 mA with a power dissipation of 500 mW. The unit operates within a temperature range of -65°C to +200°C.

Single Bipolar Transistors Feature Summary

• Hermetically sealed ceramic construction ensures environmental protection and long-term stability.

• Harsh environment radio transmission equipment

Single Bipolar Transistors Procurement Notes

Verify the specific JANTX radiation hardness level and screening lot documentation upon receipt. Confirm that the UB-3 package orientation matches the target PCB layout. Ensure storage conditions prevent moisture ingress prior to soldering, as hermetic seals must remain intact during thermal processing.

Single Bipolar Transistors Selection Notes

Select this component when radiation tolerance and high-temperature operation are critical requirements. The UB-3 package requires specific surface-mount reflow profiles distinct from standard plastic packages. Compare hFE gain ranges against circuit biasing needs, as JANTX screening may differ from commercial equivalents.

Single Bipolar Transistors Part Context

This part belongs to the 2N2222 family of NPN silicon switching transistors governed by MIL-PRF-19500/255. The JANTX suffix indicates a specific quality and radiation screening tier above JAN but below JANTXV. It serves as a ruggedized alternative to commercial SOT-23 devices in defense and aerospace sectors.

Single Bipolar Transistors Replacement Considerations

JANTXVP2N2222AUB offers higher radiation hardness levels. JANSM2N2222AUB is a MACOM equivalent with similar radiation specs. Verify pinout compatibility before substituting with non-MIL-spec variants.
