2SA1791JRL

Single Bipolar Transistors Overview

The Panasonic 2SA1791JRL is a silicon PNP epitaxial planar transistor designed for low-frequency amplification. It operates with a maximum collector-emitter voltage of -50 V and a collector current of -50 mA, dissipating up to 125 mW. The device features a high forward current transfer ratio (hFE) ranging from 200 to 500 depending on the rank, and a transition frequency (fT) of 250 MHz. Packaged in an SS-Mini3-G1 format, it serves as the complementary component to the 2SC4656.

Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank (Q or R) required for your circuit design against the datasheet specifications. Confirm that the SS-Mini3-G1 package dimensions align with your PCB footprint. Ensure compliance with standard application guidelines, avoiding use in aerospace, life support, or safety-critical systems without prior manufacturer consultation.

Single Bipolar Transistors Selection Notes

Select this component when a compact PNP transistor with a minimum -50 V rating and moderate gain is needed. The SS-Mini3-G1 package facilitates automated assembly and space-constrained designs. Consider the complementary 2SC4656 if a matched NPN pair is required for push-pull configurations.

Single Bipolar Transistors Part Context

This part belongs to Panasonic's lineup of small signal bipolar transistors intended for general-purpose amplification. It utilizes a silicon epitaxial planar structure housed in a surface-mount SS-Mini3-G1 package. The device is specifically engineered to complement the 2SC4656 NPN transistor for balanced circuit applications.

Single Bipolar Transistors Replacement Considerations

The datasheet identifies the 2SC4656 as the complementary NPN transistor. No other direct substitute part numbers are documented in the provided source material.
