KSB564ACYBU

Single Bipolar Transistors Overview

The KSB564ACYBU is a PNP epitaxial silicon bipolar junction transistor manufactured by Fairchild Semiconductor. It is housed in a TO-92 (TO-226AA) leaded package designed for through-hole mounting. The device supports a maximum collector current of 1 A and a collector-emitter breakdown voltage of 25 V. Key electrical characteristics include a DC current gain (hFE) minimum of 120 at 100 mA, a saturation voltage of 500 mV at 1 A, and a transition frequency of 110 MHz. Maximum power dissipation is rated at 800 mW with a junction temperature limit of 150 °C.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'CYBU' against official Fairchild or ON Semiconductor documentation to confirm pinout orientation and lead-free compliance status. Ensure the ordering part number matches the exact datasheet revision required for your design specifications. Cross-reference manufacturer catalogs to confirm current production status and availability constraints.

Single Bipolar Transistors Selection Notes

Select this component when a low-voltage PNP transistor with moderate current handling is required. The 25 V rating suits low-power logic interfaces and audio stages. Verify that the TO-92 package fits the PCB footprint and that the 800 mW dissipation capability meets thermal requirements without excessive heatsinking.

Single Bipolar Transistors Part Context

This transistor belongs to the KSB series of PNP epitaxial silicon devices. It serves as the complementary counterpart to the KSD471A NPN transistor, facilitating push-pull output stage designs. The series is characterized by balanced electrical parameters suitable for general-purpose analog and digital switching tasks.
