The Infineon BCR183UE6327HTSA1 is a dual PNP pre-biased transistor in a SC-74 (SOT-457) surface-mount package. Each of the two PNP transistors integrates a 10kΩ base resistor and a 10kΩ emitter-base resistor, eliminating the need for external bias components. With a collector-emitter breakdown voltage of 50V and a maximum collector current of 100mA, it is suited for switching and interface applications in industrial control, consumer electronics, and automotive modules where space and component count matter. The 200MHz transition frequency supports moderate-speed switching up to the low-MHz range.
The BCR183UE6327HTSA1 carries a Last Buy lifecycle status. This means Infineon has announced end-of-life for this product, and the final purchase window is open. Once the Last Buy period closes, the part will no longer be manufactured. For existing designs, securing inventory now through the remaining allocation is the standard approach. For new designs, a pin-compatible alternative should be qualified.
The 10kΩ base and emitter-base resistors set a fixed bias point: with a typical base current of 500µA, the collector saturation voltage is 300mV at 10mA load.
