2SD12700P

Single Bipolar Transistors Overview

The Panasonic 2SD1270P is a silicon NPN epitaxial planar power transistor designed for switching applications. It features a TO-220F-A1 full-pack package suitable for heat sink mounting with a single screw. Key electrical parameters include a collector-emitter voltage (VCEO) of 80 V, a continuous collector current (IC) of 5 A, and a peak collector current (ICP) of 10 A. The device offers a low collector-emitter saturation voltage (VCE(sat)) of 0.5 V at IC = 4 A and IB = 0.2 A. Transition frequency (fT) is rated at 30 MHz. Collector power dissipation reaches 40 W at TC = 25°C.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'P' against official documentation to confirm package or ranking details. Check the manufacturer's website for the latest lifecycle status, as this component may be in maintenance or discontinued phases. Ensure compliance with RoHS directives if required by your application standards. Confirm absolute maximum ratings match your circuit conditions before procurement.

Single Bipolar Transistors Selection Notes

Select this component for applications requiring high collector current up to 5 A and robust thermal management via the TO-220F-A1 package. Consider the 80 V breakdown voltage for medium-voltage switching tasks. Evaluate the hFE rank requirements (R, Q, or P) based on base drive capabilities. Ensure adequate heat sinking is provided to maintain junction temperature within the 150°C limit during operation.

Single Bipolar Transistors Part Context

The 2SD1270 is part of Panasonic's silicon NPN epitaxial planar transistor series. It is complementary to the 2SB0945 PNP transistor. The device is manufactured using planar technology optimized for power switching. It falls under the category of general-purpose power transistors intended for standard electronic applications rather than specialized aerospace or medical uses.

Single Bipolar Transistors Replacement Considerations

Consult official datasheets for direct replacements. Verify pinout compatibility (Base, Collector, Emitter) and package dimensions (TO-220F-A1). Ensure replacement parts meet or exceed the 80 V VCEO, 5 A IC, and 40 W PC specifications. Check for equivalent hFE ranks and saturation voltages to maintain circuit performance.
