Product details

The Infineon BCR108WE6327BTSA1 is an NPN pre-biased transistor in a SC-70 (SOT-323) surface-mount package. It integrates a 2.2 kΩ base resistor (R1) and a 47 kΩ emitter-base resistor (R2), so you can drive it directly from a microcontroller or logic output without external biasing components. The transistor is rated for 50 V collector-emitter breakdown, 100 mA continuous collector current, and a maximum power dissipation of 250 mW.

Obsolete — sourcing reality

This part is officially obsolete per the manufacturer. There is no official successor listed, so you will need to qualify a pin-compatible alternative or redesign the footprint.

The 50 V VCEO and 100 mA IC are the hard limits — any replacement must meet or exceed these. The 250 mW power ceiling in the SC-70 package means thermal derating is tight; a higher-rated part in the same footprint may not be a drop-in if it dissipates more. The integrated 2.2 kΩ / 47 kΩ resistor divider sets the on/off threshold — a substitute with different resistor values will shift the base drive and may not switch at the same logic level.

Frequently asked questions

What is the replacement for BCR108WE6327BTSA1?

There is no official replacement listed by Infineon. You will need to evaluate a pin-compatible NPN pre-biased transistor with the same 2.2 kΩ base and 47 kΩ emitter-base resistors in SC-70 (SOT-323) package, or redesign the circuit around a discrete transistor and two resistors.
