2N4033UB/TR

Single Bipolar Transistors Overview

The Microchip Technology 2N4033UB/TR is a PNP silicon bipolar junction transistor (BJT) designed for through-hole mounting in the TO-39-3 package. It supports a maximum DC collector current of 1 A and withstands collector-emitter and collector-base voltages of 80 V, with an emitter-base voltage rating of 5 V. The device dissipates up to 800 mW and operates within a temperature range of -65°C to +200°C. Key electrical characteristics include a collector-emitter saturation voltage of 1 V, a minimum DC current gain (hFE) of 25 at 1 A, and a maximum hFE of 300 at 100 mA.

Single Bipolar Transistors Feature Summary

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'UB' against official Microchip documentation to confirm exact binning or screening levels, as suffixes often denote specific manufacturing lot attributes. Ensure procurement channels provide traceability certificates required for qualified components. Confirm that the TO-39-3 lead configuration matches the target PCB footprint before finalizing orders.

Single Bipolar Transistors Selection Notes

Select this component when a ruggedized PNP BJT is required for high-temperature environments exceeding standard commercial limits. The TO-39-3 package offers superior thermal dissipation compared to plastic equivalents. Evaluate the 80 V voltage rating against circuit requirements to ensure adequate headroom. Consider the 1 A current capacity for load handling needs in discrete amplifier or switch topologies.

Single Bipolar Transistors Part Context

This part belongs to the 2N4033 family of military-grade PNP transistors manufactured by Microchip Technology. It shares core specifications with variants like Jan2N4033 but may differ in qualification standards or screening procedures based on the UB suffix. The TO-39-3 hermetic package distinguishes it from commercial plastic-packaged counterparts, targeting sectors demanding extended operational lifespans and radiation hardness.

Single Bipolar Transistors Replacement Considerations

Consult official cross-reference lists for verified substitutes such as Jan2N4033 or Jantx2N4033. Verify pinout compatibility and thermal resistance values before substituting. Ensure replacement parts meet the same environmental and voltage ratings.
