Product details

Pre-biased NPN for space-constrained switching

The BCR 108T E6327: The Infineon BCR 108T is an NPN pre-biased digital transistor in a SC-75 (SOT-416) surface-mount package. It integrates a 2.2 kOhms base resistor (R1) and a 47 kOhms emitter-base resistor (R2), eliminating two external passives from the board.

The 170 MHz transition frequency (fT) is adequate for switching up to several megahertz, typical for load drivers, relay coils, or logic-level translation. The 300 mV Vce saturation at 500 µA base and 10 mA collector ensures low on-state voltage drop, keeping dissipation within the 250 mW package limit. The 100 nA collector cutoff current (ICBO) is tight enough for battery-powered circuits where leakage matters. Minimum DC current gain (hFE) of 70 at 5 mA collector current and 5 V Vce provides consistent drive capability across production lots. The pre-biased resistors set a fixed base current, so the designer does not need to calculate external bias networks — just drive the input pin with a logic-level signal.

Infineon lists the BCR 108T as obsolete. No direct replacement is specified in the available records.
