2SA1725

Single Bipolar Transistors Overview

The Sanken Electric USA Inc. 2SA1725 is a silicon PNP epitaxial planar transistor designed as the complement to the 2SC4511 NPN type. It features an absolute maximum collector-emitter voltage (VCEO) of -80 V and a continuous collector current (IC) rating of -6 A at 25°C case temperature. The device operates with a junction temperature range from -55°C to +150°C and supports up to 30 W power dissipation under specified thermal conditions. Key electrical characteristics include a minimum DC current gain (hFE) of 50, a typical transition frequency (fT) of 20 MHz, and a low collector-emitter saturation voltage of -0.5 V max at IC = -2 A.

Single Bipolar Transistors Feature Summary

• Complementary pairing with the 2SC4511 NPN transistor for matched circuit applications
• High current handling capability suitable for audio and general-purpose switching
• Low saturation voltage for efficient power management

Single Bipolar Transistors Applications

• Audio amplifier circuits
• General-purpose switching applications

Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank (O, P, or Y) required for your design, as gain varies by binning. Confirm thermal management requirements, as the 30 W rating assumes a 25°C case temperature; natural cooling derating must be calculated based on actual operating conditions. Ensure the TO-220F package dimensions align with your PCB layout constraints.

Single Bipolar Transistors Selection Notes

Select this component when a PNP counterpart to the 2SC4511 is needed for push-pull or complementary configurations. Consider the -80 V breakdown voltage and -6 A current capacity against load requirements. Evaluate the thermal resistance characteristics if heatsinking is not utilized, as power dissipation drops significantly without external cooling.

Single Bipolar Transistors Part Context

This transistor belongs to Sanken's lineup of silicon PNP epitaxial planar devices. It is specifically engineered to match the performance profile of the 2SC4511 NPN transistor, facilitating balanced design in differential pairs and output stages. The TO-220F package provides robust mechanical stability and thermal conductivity for through-hole mounting.
