2SA1493

Single Bipolar Transistors Overview

The Sanken Electric USA Inc. 2SA1493 is a Silicon PNP Epitaxial Planar Transistor designed for audio and general-purpose applications, serving as the complement to the 2SC3857 type. It features a collector-base voltage (VCBO) of -200 V and a collector-emitter voltage (VCEO) of -200 V. The device supports a maximum continuous collector current (IC) of -15 A and dissipates up to 150 W at a case temperature of 25°C. Key electrical characteristics include a minimum DC current gain (hFE) of 50 at IC=-50mA and VCE=-4V, with a typical transition frequency (fT) of 20 MHz. The transistor utilizes an MT-200 through-hole package.

Single Bipolar Transistors Feature Summary

• Robust current handling capacity rated for -15 A continuous collector current in standard operating conditions.
• Complementary design specifically matched to the 2SC3857 NPN transistor for balanced push-pull circuit configurations.

Single Bipolar Transistors Applications

• Audio amplifier output stages
• General-purpose high-power switching circuits

Single Bipolar Transistors Procurement Notes

Verify component authenticity by checking the marking code against official Sanken Electric documentation. Confirm the specific hFE rank (O, P, or Y) required for your application, as gain varies significantly between subtypes. Ensure thermal management solutions align with the specified derating curves for the MT-200 package to maintain reliability under load.

Single Bipolar Transistors Selection Notes

Select this component when a high-voltage PNP transistor is needed to pair with the 2SC3857. Evaluate the thermal resistance requirements based on the intended duty cycle and heatsinking capabilities. Consider the transition frequency limitations if high-speed switching beyond audio frequencies is required, as the fT is optimized for lower-frequency power applications.

Single Bipolar Transistors Part Context

This transistor belongs to Sanken's lineup of epitaxial planar power transistors. It is engineered for robust performance in linear and switching modes. The MT-200 package provides a reliable mechanical interface for through-hole mounting, facilitating integration into traditional PCB designs where high current and voltage isolation are critical.

Single Bipolar Transistors Replacement Considerations

The datasheet explicitly states that this part is not recommended for new designs. When replacing existing units, ensure the substitute matches the -200 V rating and -15 A current capacity. Verify pinout compatibility with the MT-200 footprint to avoid circuit modification.
