KSB1151YSTSTU

Single Bipolar Transistors Overview

The KSB1151YSTSTU is a discontinued PNP epitaxial silicon transistor manufactured by onsemi. It features a TO-126AA package with specific terminal lengths defined by the YSSTU suffix. The device supports a maximum collector current of -5 A and a pulse current of -8 A, with a collector-emitter voltage rating of -60 V. DC current gain ranges from 50 to 400 depending on the hFE classification. Power dissipation is rated at 1.3 W at 25°C ambient temperature and 20 W at 25°C case temperature.

Single Bipolar Transistors Procurement Notes

This component is officially discontinued and not recommended for new designs. Buyers must verify availability through authorized onsemi representatives as standard distribution channels no longer stock this part. Compliance with RoHS standards should be confirmed via official documentation before procurement attempts.

Single Bipolar Transistors Selection Notes

Engineers should evaluate alternative active components due to the discontinuation status of the KSB1151YSTSTU. Design validation requires checking thermal derating curves and safe operating area limits under actual load conditions. Verify that the TO-126AA package dimensions match the PCB footprint requirements.

Single Bipolar Transistors Part Context

The KSB1151 belongs to the KSB series of PNP epitaxial silicon transistors originally developed by Fairchild Semiconductor and later acquired by onsemi. This series is designed for medium-power applications requiring high current handling and low saturation voltages in discrete semiconductor form factors.
