2SA1707T-AN

Single Bipolar Transistors Overview

The onsemi 2SA1707T-AN is a PNP epitaxial planar silicon bipolar junction transistor (BJT) designed for general-purpose switching applications. It features a maximum collector-emitter voltage of 50 V and a continuous collector current rating of 3 A. The device operates with a power dissipation capacity of 1 W and exhibits a transition frequency of 150 MHz. Key electrical characteristics include a DC current gain of at least 200 at 100 mA, and a saturation voltage of 700 mV at 2 A. It is housed in the 3-NMP surface-mount package and supports an operating junction temperature up to 150°C.

Single Bipolar Transistors Procurement Notes

Verify component authenticity through authorized channels as this part is officially discontinued by the manufacturer. Confirm that the 3-NMP package dimensions align with existing PCB footprints. Ensure design-in documentation references the specific datasheet version to account for any historical manufacturing changes or RoHS compliance updates prior to end-of-life status.

Single Bipolar Transistors Selection Notes

Select this component when a PNP BJT with 50 V breakdown and 3 A current handling is required in a small surface-mount form factor. Consider the 150 MHz transition frequency for moderate-speed switching needs. Evaluate thermal management requirements given the 1 W power dissipation limit in the 3-NMP package. Compare against legacy replacements if redesigning existing equipment.

Single Bipolar Transistors Part Context

This transistor belongs to the 2SA1707 series from onsemi, a line of standard discrete semiconductors intended for consumer and industrial electronics. The 3-NMP package provides a compact solution for space-constrained designs. As a PNP device, it complements NPN counterparts in push-pull configurations or single-ended switching topologies within power supply and driver circuits.
