2SA1909

Single Bipolar Transistors Overview

The 2SA1909 is a Silicon PNP Epitaxial Planar Transistor designed as the complement to the 2SC5101. It features a collector-base voltage of -140 V, collector-emitter voltage of -140 V, and emitter-base voltage of -6 V. The device supports a maximum continuous collector current of -10 A and dissipates up to 80 W at 25°C case temperature. Key electrical characteristics include a minimum DC current gain (hFE) of 50, a typical transition frequency (fT) of 20 MHz, and a maximum collector-emitter saturation voltage of -0.5 V under specified conditions.

Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank suffix (O, P, or Y) required for your design, as these denote distinct gain ranges. Confirm that the FM100 (TO-3P) package dimensions align with your thermal management strategy. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing standards.

Single Bipolar Transistors Selection Notes

Select this component when a high-voltage PNP transistor is needed to match the 2SC5101. Consider the 80 W power dissipation rating and the need for an appropriate heatsink to maintain safe operating temperatures. Evaluate the -140 V breakdown voltage against your circuit's peak voltage requirements.
