The built-in bias resistors — 10 kOhms base (R1) and 47 kOhms emitter-base (R2) — eliminate two external passives from the BOM, saving placement cost and board area in high-volume ECU modules. Collector-emitter breakdown is rated at 50 V, with a maximum collector current of 100 mA and power dissipation of 200 mW. The 150 MHz transition frequency is adequate for switching loads up to the low-MHz range, typical for relay drivers, solenoid pre-drivers, and logic-level interface circuits in 12 V automotive environments. ## Package and footprint Supplied in a PG-SOT23 (TO-236-3, SC-59, SOT-23-3) package, surface-mount only. The three-pin footprint matches standard SOT-23 land patterns. No exposed pad; thermal dissipation relies on the package body and PCB copper.","metaTitle":"BCR135E6433HTMA1 NPN Pre-Biased Transistor, 50V 100mA","metaDescription":"Infineon BCR135E6433HTMA1 NPN pre-biased transistor, 50V Vce, 100mA Ic, 150MHz ft, AEC-Q101 qualified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Grade":"Automotive","Series":"-","Package":"Tape & Reel (TR)","Power - Max":"200 mW","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Obsolete","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR135","Resistor - Base (R1)":"10 kOhms","Frequency - Transition":"150 MHz","Supplier Device Package":"PG-SOT23","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":"$0.0474","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/393aee626b2da6d96af91aaeea0af3f8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BCR135E6433HTMA1?","answer":"For a pin-compatible pre-biased NPN in SOT-23 with the same resistor ratio (10 kOhm base / 47 kOhm emitter-base), evaluate Infineon's current BCR135 series variants or a cross from Nexperia (PDTC series) or Rohm (DTC series) — verify AEC-Q101 grade and package compatibility before substituting."},{"question":"Is BCR135E6433HTMA1 AEC-Q101 qualified?","answer":"Yes, it carries AEC-Q101 qualification, making it suitable for automotive applications where the part is still available through surplus or broker channels."},{"question":"What package is BCR135E6433HTMA1?","answer":"PG-SOT23, also described as TO-236-3, SC-59, SOT-23-3.
