FJPF9020TU

Single Bipolar Transistors Overview

The FJPF9020TU is a PNP epitaxial Darlington transistor manufactured by onsemi, formerly Fairchild Semiconductor. It features monolithic construction with built-in base-emitter shunt resistors (R1 ≈ 0 Ω, R2 ≈ 50 Ω). The device supports a collector current of 2 A and a collector-base voltage of -550 V. Key electrical parameters include a DC current gain (hFE) of 400 to 700 at -1 A and -4 V, and a collector-emitter saturation voltage of 1.5 V maximum at -1 A and -20 mA base current. It operates up to a junction temperature of 150 °C and dissipates 15 W in a TO-220F-3 package.

Single Bipolar Transistors Procurement Notes

Verify the component status as obsolete or discontinued through official manufacturer channels before procurement planning. Confirm that the specific ordering suffix TU corresponds to the tube packaging format documented in the datasheet. Ensure compatibility with existing thermal management designs given the 15 W dissipation rating in the TO-220F-3 package. Validate RoHS compliance status against current regulatory requirements for the intended deployment region.

Single Bipolar Transistors Selection Notes

Select this component for applications requiring high voltage blocking capabilities combined with significant current handling. The integrated shunt resistors simplify biasing networks compared to standard Darlington configurations. Evaluate the thermal resistance characteristics to ensure adequate heat sinking for continuous operation near the 15 W limit. Consider the saturation voltage specifications when designing low-loss power paths.
