Two matched NPNs with integrated bias — saves board space and resistor count
The Infineon BCR133SH6327XTSA1 packs two 10kΩ base and 10kΩ emitter-base pre-biased NPN transistors into a single PG-SOT363-PO package. Each transistor is rated for 50V collector-emitter breakdown and 100mA continuous collector current, with a minimum DC current gain of 30 at 5mA, 5V. The 130MHz transition frequency keeps switching clean in low-speed digital and analog loads like relay drivers, LED indicators, or level shifters where you would otherwise place two discrete transistors and four resistors.
Last Buy — plan your final order window
Infineon has placed the BCR133SH6327XTSA1 into Last Buy status. That means the manufacturer has announced a final production run and will stop taking orders after a set date. If this part is on your BOM, you need to secure lifetime-buy quantities now or qualify a replacement before the window closes.
The 300mV saturation voltage at 500µA base, 10mA collector is typical for this resistor ratio.
