2N2432AUB/TR

Single Bipolar Transistors Overview

The 2N2432AUB/TR is a silicon NPN small-signal bipolar junction transistor (BJT) manufactured by Microchip Technology. It utilizes a TO-18-3 hermetic ceramic package designed for through-hole mounting. The device supports a maximum DC collector current of 100 mA and withstands a collector-emitter voltage (VCEO) of 45 V, with a matching collector-base voltage (VCBO) of 45 V. Power dissipation is rated at 600 mW. The component operates within an extended temperature range from -65 °C to +175 °C. DC current gain (hFE) ranges from a minimum of 30 to a maximum of 400.

Single Bipolar Transistors Feature Summary

• Hermetic TO-18-3 ceramic construction suitable for high-reliability environments
• Extended operating temperature capability up to +175 °C
• Single NPN configuration optimized for small-signal applications

Single Bipolar Transistors Applications

• Military aerospace electronic systems
• High-reliability industrial control circuits
• Harsh environment signal amplification

Single Bipolar Transistors Procurement Notes

Verify the specific suffix /TR against official Microchip documentation to confirm tape-and-reel packaging specifications, as standard military variants often utilize waffle pack or tube formats. Confirm RoHS compliance status directly with the manufacturer, as historical data indicates non-compliance for similar JANTX series parts. Validate that the TO-18-3 lead form matches the target PCB footprint requirements before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when a hermetically sealed NPN transistor is required for high-temperature operation exceeding standard commercial limits. The 45 V rating and 100 mA current capacity define its suitability for low-power switching and linear amplification tasks. Ensure the application can accommodate the physical dimensions and thermal characteristics of the TO-18-3 ceramic package compared to plastic alternatives.

Single Bipolar Transistors Part Context

This part belongs to the 2N2432 family of NPN transistors produced by Microchip Technology under its Microsemi division. The /TR suffix denotes a specific packaging variant, typically tape and reel, distinct from the standard bulk-packaged 2N2432AUB. These devices are engineered for defense and aerospace sectors requiring radiation tolerance and long-term stability in extreme conditions.

Single Bipolar Transistors Replacement Considerations

Consult official Microchip cross-reference guides for verified substitutes. Generic equivalents may lack the hermetic sealing and extended temperature range of the original component.
