Dual 47k/47k NPN array in SOT-363 — last-buy status
The Infineon BCR148SH6327XTSA1 packs two matched NPN transistors with integrated bias resistors — 47 kΩ base and 47 kΩ emitter-base — into a single PG-SOT363-PO package. Each transistor handles a collector current of 100 mA and a collector-emitter breakdown of 50 V, with a saturation voltage of 300 mV at 10 mA. The 100 MHz transition frequency suits low-speed switching and interface buffering in 12 V or 24 V industrial logic. The total package power dissipation is 250 mW, so the thermal budget is tight when both transistors are conducting simultaneously — derate per the datasheet thermal curve above 25 °C.
Last Buy — LTB window is open
Infineon has placed the BCR148SH6327XTSA1 into Last Buy status. This means the manufacturer has announced final orders, and once that window closes the only channel will be surplus or broker stock. Buyers should secure their lifetime buy quantities now or qualify a pin-compatible alternative before the cut-off.
