The 130 MHz transition frequency keeps switching edges clean for sub-1 MHz PWM or data-line buffering. The built-in 10 kΩ base and 10 kΩ base-emitter resistors eliminate two external passives per transistor — a board-space win in dense SOT-723 layouts. ## PG-TSFP-3 footprint — SOT-723 land pattern The supplier device package is PG-TSFP-3, which maps to the standard SOT-723 footprint. That 1.2 mm × 1.2 mm body with 0.4 mm pitch is common among pre-biased transistors from multiple manufacturers, so a replacement search should start with parts in that same land pattern. The surface-mount assembly is straightforward for reflow, though the small pad area means the 250 mW power limit is the real thermal ceiling — no heatsinking is practical at this scale.","metaTitle":"Infineon BCR 133F B6327 NPN Pre-Biased Transistor, 50 V","metaDescription":"Infineon BCR 133F B6327 NPN pre-biased transistor, 50 V VCEO, 100 mA Ic, 130 MHz ft, dual 10 kΩ resistors, SOT-723.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR)","Power - Max":"250 mW","Mounting Type":"Surface Mount","Package / Case":"SOT-723","Product Status":"Obsolete","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR 133","Resistor - Base (R1)":"10 kOhms","Frequency - Transition":"130 MHz","Supplier Device Package":"PG-TSFP-3","Resistor - Emitter Base (R2)":"10 kOhms","Vce Saturation (Max) @ Ib, Ic":"300mV @ 500µA, 10mA","Current - Collector (Ic) (Max)":"100 mA","Current - Collector Cutoff (Max)":"100nA (ICBO)","DC Current Gain (hFE) (Min) @ Ic, Vce":"30 @ 5mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/da5fc9ead9e2b22151fb962c98fc84f4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the recommended replacement for BCR 133F B6327?","answer":"Infineon has not published an official successor order code for the BCR 133F B6327 in the available records. A pin-compatible replacement would need to match the SOT-723 (PG-TSFP-3) footprint, NPN pre-biased topology, and the dual 10 kΩ resistor values.
