2SD1628F-TD-H

Single Bipolar Transistors Overview

The onsemi 2SD1628F-TD-H is a single NPN bipolar junction transistor housed in a PCP (SOT-89/TO-243) surface-mount package. It supports a maximum collector current of 5 A and a collector-to-emitter voltage of 20 V, with a pulse rating of 8 A. The device features a gain-bandwidth product of 120 MHz and a DC current gain (hFE) rank F ranging from 160 to 320 at 0.5 A. Key electrical limits include a collector cutoff current of 100 nA and a collector-to-emitter saturation voltage of 500 mV at 3 A. Thermal ratings specify a junction temperature of 150 °C and power dissipation of 500 mW.

Single Bipolar Transistors Feature Summary

Single Bipolar Transistors Procurement Notes

Verify the specific 'F' ranking suffix to ensure the hFE range meets circuit requirements, as this variant specifies gains between 160 and 320. Confirm that the PCP package dimensions align with the target PCB land pattern. Check RoHS and halogen-free compliance status if environmental regulations apply to the final assembly. Ensure thermal management strategies account for the 500 mW dissipation limit without an external heatsink.

Single Bipolar Transistors Selection Notes

Select this component when low saturation voltage and high current handling are required in a compact form factor. The 20 V rating suits low-voltage logic and power applications. Compare against other ranks like E or G if higher current gain thresholds are necessary for base drive efficiency. Evaluate the 120 MHz transition frequency against the required switching speed of the application to ensure adequate performance margins.

Single Bipolar Transistors Part Context

This part belongs to the 2SD1628 family of NPN transistors manufactured by onsemi. The family includes variants such as 2SD1628G-TD-E and 2SD1628F-TD-E, which share identical electrical characteristics but differ in hFE ranking and packaging compliance markings. The PCP package corresponds to JEITA SC-62 and JEDEC SOT-89 standards, providing a standardized footprint for surface-mount assembly.
