No official Infineon successor order code is listed, so pin-compatible substitution requires a cross-reference search against the BCR148 base number. ## What it is — pre-biased NPN in a tiny package The BCR148WE6327BTSA1 is a pre-biased NPN transistor from Infineon, integrating two 47 kOhm resistors — one in series with the base (R1) and one between the emitter and base (R2). This built-in bias network eliminates two external resistors from the board, saving placement cost and PCB area. It is housed in a surface-mount SC-70 (SOT-323) package, specifically the PG-SOT323 variant, and rated for a maximum power dissipation of 250 mW. ## Key ratings — 100 mA, 50 V, 100 MHz Collector current is rated at 100 mA maximum, with a collector-emitter breakdown voltage of 50 V. The transition frequency (fT) is 100 MHz, making it suitable for switching applications up to low-MHz ranges. DC current gain (hFE) is minimum 70 at 5 mA collector current and 5 V Vce. Vce saturation is 300 mV maximum at 500 µA base current and 10 mA collector current. Collector cutoff current is just 100 nA (ICBO), useful for low-leakage designs. ## Where it fits — switching and driver circuits This pre-biased transistor is a natural fit for low-side switching, relay and solenoid drivers, and logic-level interface circuits where you want to drive a load from a microcontroller GPIO without adding external resistors. The SC-70 package suits space-constrained designs like sensor modules, portable devices, and IoT edge nodes.","metaTitle":"BCR148WE6327BTSA1 NPN Pre-Biased Transistor, 100 mA, 50 V","metaDescription":"Infineon BCR148WE6327BTSA1 NPN pre-biased transistor in SC-70/SOT-323. 100 mA Ic, 50 V Vce, 47k+47k resistor network.","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":"SC-70, SOT-323","Product Status":"Obsolete","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR148","Resistor - Base (R1)":"47 kOhms","Frequency - Transition":"100 MHz","Supplier Device Package":"PG-SOT323","Resistor - Emitter Base (R2)":"47 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":"70 @ 5mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/48b524a21f70ba87148fe966031e06a7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BCR148WE6327BTSA1?","answer":"A pin-compatible cross-reference search against the BCR148 base product number is the practical path for substitution."},{"question":"What is the maximum current for BCR148WE6327BTSA1?","answer":"The maximum collector current (Ic) is 100 mA.
