It integrates two 10 kOhm resistors — one in series with the base, one between base and emitter — so you drop the two external passives from the BOM for low-side switching, relay drivers, or logic-level interface circuits. Collector-emitter breakdown is rated at 50 V, continuous collector current at 100 mA, and the transition frequency hits 130 MHz. ## Sourcing this part now that it's obsolete Infineon lists the BCR 133F as Obsolete. That means the factory line has stopped, and the only available stock sits in independent distribution or surplus channels. No official replacement part number is published by Infineon for this exact order code. If you need a drop-in pre-biased NPN in SOT-723 with 10 kOhm resistors, the closest functional equivalent would be another manufacturer's part with the same resistor values and package — but pin compatibility must be verified against your board layout.","metaTitle":"Infineon BCR 133F E6327 NPN Pre-Biased Transistor, 50 V","metaDescription":"Infineon BCR 133F E6327 NPN pre-biased transistor, 50 V Vce, 100 mA Ic, 130 MHz ft, SOT-723.
