KSD362RTU

Single Bipolar Transistors Overview

The KSD362RTU is a discontinued NPN epitaxial silicon transistor manufactured by onsemi, originally designed for black and white television horizontal deflection output applications. It utilizes a TO-220 package with three leads. The device supports a maximum collector current of 5 A and a power dissipation of 40 W at 25°C case temperature. Key voltage ratings include a collector-base voltage of 150 V, a collector-emitter voltage of 70 V, and an emitter-base voltage of 8 V. The component operates within a junction temperature range up to 150°C.

Single Bipolar Transistors Procurement Notes

Verify the obsolete status of this component before initiating any procurement process. Confirm that the manufacturer has officially ceased production and that no active manufacturing orders are possible. Evaluate alternative sources carefully, as availability may be restricted to surplus or secondary markets only. Ensure compatibility with existing designs given the discontinuation.

Single Bipolar Transistors Selection Notes

Select this component only if the specific design requirements align with its historical application in television deflection circuits. Consider the limitations imposed by its discontinued status when planning long-term product lifecycles. Verify that the TO-220 package dimensions and pinout match the target PCB layout. Assess whether modern replacements offer equivalent electrical characteristics without redesigning the circuit board.

Single Bipolar Transistors Part Context

This part belongs to the broader category of bipolar junction transistors (BJTs) produced by Fairchild Semiconductor, which was later acquired by onsemi. The KSD362 series was historically significant in consumer electronics, particularly for analog television sets. Its specifications reflect the technology standards of the late 20th century, focusing on high current handling and moderate voltage ratings suitable for deflection yoke driving.
