Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer source, as the KSD362 was originally produced by Fairchild Semiconductor. Confirm availability status, as many distributors list this component as obsolete or discontinued. Ensure the suffix 'N' aligns with the required packaging and RoHS compliance specifications for your design. Cross-reference datasheet revisions to confirm electrical characteristics match your circuit requirements before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component when designing B/W TV deflection circuits requiring a 5 A NPN switch. Verify that the 70 V collector-emitter voltage meets the peak voltage demands of the flyback transformer. Ensure adequate heatsinking is provided to maintain the case temperature at 25°C for full 40 W power dissipation. Check the hFE classification (N, R, or O) to ensure proper base drive current calculations are accurate for saturation.

Single Bipolar Transistors Part Context

The KSD362 belongs to a family of power transistors historically used in consumer electronics, particularly television sets. Originally manufactured by Fairchild Semiconductor, it represents a standard solution for horizontal deflection outputs in analog video equipment. The part is distinct from modern MOSFET-based designs, relying on bipolar junction technology for its switching performance.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the KSC2233 and KSD1362, which share similar deflection output characteristics. Verify pinout compatibility and absolute maximum ratings before swapping components in existing designs.
