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.","metaTitle":"BCR108WE6327BTSA1 NPN Pre-Biased Transistor, 50 V, 100 mA","metaDescription":"Infineon BCR108WE6327BTSA1 NPN pre-biased transistor, 50 V VCEO, 100 mA IC, 250 mW, SC-70 SOT-323.
