2SC57390P

Single Bipolar Transistors Overview

The Panasonic 2SC5739 is a silicon NPN epitaxial planar power transistor designed for audio/visual equipment and industrial DC-DC converters. It features high-speed switching with short storage and fall times, low collector-emitter saturation voltage, and superior forward current transfer ratio linearity. The device operates in a TO-220D package with built-in isolation, guaranteeing a withstand voltage of 5 kV. Absolute maximum ratings include a collector-emitter voltage of 60 V, continuous collector current of 3 A, and peak collector current of 6 A. Power dissipation reaches 20 W at 25°C ambient temperature.

Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank classification required for your design, as the component is available in Q and P ranks with distinct gain ranges. Confirm that the TO-220D-A1 package dimensions align with your thermal management strategy. Ensure compliance with standard application guidelines, avoiding use in safety-critical or life-support systems without prior consultation. Check the manufacturer's website for the latest lifecycle status to confirm availability.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring fast switching speeds and low saturation voltage in a robust, insulated package. The 60 V collector-emitter rating suits moderate voltage applications. Consider the thermal resistance characteristics for heat sink requirements, noting the significant difference between free-air and mounted dissipation capabilities. Verify that the transition frequency meets the operational bandwidth needs of the target circuit.
