2SD1803T-H

Single Bipolar Transistors Overview

The onsemi 2SD1803T-H is a single NPN silicon bipolar junction transistor housed in the TP package, which corresponds to the SC-64 and TO-251 form factors. It supports a maximum collector current of 5 A and a collector-to-emitter voltage of 50 V. The device features a gain-bandwidth product of 180 MHz at 1 A and exhibits low collector-to-emitter saturation voltage. It operates with a junction temperature up to 150 °C and includes Pb Free and Halogen Free compliance.

Single Bipolar Transistors Procurement Notes

Verify that the specific ordering suffix matches the required packaging format. The 'H' suffix indicates Pb Free and Halogen Free compliance, while the 'T' suffix designates the TP (TO-251) package type. Confirm the minimum packing quantity requirements for the selected variant before procurement.

Single Bipolar Transistors Selection Notes

Select this component for circuits requiring robust high-current handling capabilities combined with fast switching performance. Ensure the thermal management strategy accommodates the specified power dissipation limits. Verify that the base drive currents are sufficient to maintain the transistor within the desired saturation region during operation.

Single Bipolar Transistors Part Context

This part belongs to the 2SD1803 series of NPN transistors manufactured by onsemi. It is functionally paired with the 2SB1203 PNP transistor within the same datasheet documentation. Both devices share identical electrical characteristics and physical dimensions, facilitating complementary push-pull circuit designs.

Single Bipolar Transistors Replacement Considerations

The 2SD1803T-E serves as a direct functional substitute, differing only in the absence of the Halogen Free designation associated with the H suffix.
