50V, 100mA dual pre-biased NPN — the selection mistake this avoids
The Infineon BCR119SH6327 is an automotive-grade dual NPN transistor with integrated bias resistors, in a 6-VSSOP / SOT-363 package. The R1 base resistor is 4.7kΩ, eliminating two external resistors per channel and saving board space in high-density ECU layouts. Collector-emitter breakdown is rated at 50V with a maximum collector current of 100mA, covering typical low-current solenoid drives, logic-level level shifters, and CAN/LIN bus interface pull-up circuits in 12V and 24V vehicle architectures.
AEC-Q101 — capable is not qualified
An industrial-grade transistor substituted here would need its own PPAP — the OEM auditor will ask for the qualification report, and the BCR119SH6327 has it on file.
Package and mounting
Surface-mount in PG-SOT363-6-1 (SC-88 compatible footprint). The 250mW power dissipation limit means the junction temperature stays within the 150°C absolute-maximum when each channel sinks about 50mA continuously at 50V — derate for ambient above 85°C. The dual NPN shares the same substrate, so thermal coupling between channels is tight; keep the total dissipation under the package ceiling.
