Each transistor integrates a 2.2 kΩ base resistor and a 47 kΩ emitter-base resistor, eliminating the need for external bias components in switching applications. With a 50 V collector-emitter breakdown voltage and 100 mA maximum collector current, it is sized for low-current loads like relay coils, LED indicators, and logic-level interface circuits. The 170 MHz transition frequency keeps switching edges clean for digital signals up to a few MHz. ## Obsolete — sourcing reality This part carries an Obsolete lifecycle status, meaning Infineon has ended production. For existing BOM lines, the only channel is independent distribution — surplus inventory, new-old-stock, or broker-sourced material. ## 250 mW ceiling and saturation behaviour Total power dissipation is rated at 250 mW for the dual package. With both transistors conducting, each channel's share depends on duty cycle and ambient temperature — the SOT-363 footprint offers limited copper area for heat spreading.","metaTitle":"BCR108SE6433HTMA1 Dual NPN Pre-Biased Transistor, 50V, 100mA","metaDescription":"Infineon BCR108SE6433HTMA1 dual NPN pre-biased transistor in SOT-363. 50V VCEO, 100mA IC, 170MHz fT.","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":"250mW","Mounting Type":"Surface Mount","Package / Case":"6-VSSOP, SC-88, SOT-363","Product Status":"Obsolete","Transistor Type":"2 NPN - Pre-Biased (Dual)","lifecycle_stage":"eol_hot","Base Product Number":"BCR108","Resistor - Base (R1)":"2.2kOhms","Frequency - Transition":"170MHz","Supplier Device Package":"PG-SOT363-PO","Resistor - Emitter Base (R2)":"47kOhms","Vce Saturation (Max) @ Ib, Ic":"300mV @ 500µA, 10mA","Current - Collector (Ic) (Max)":"100mA","Current - Collector Cutoff (Max)":"-","DC Current Gain (hFE) (Min) @ Ic, Vce":"70 @ 5mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ca1544aaf2aafd2d035881c4e6e72774.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BCR108SE6433HTMA1 obsolete?","answer":"Yes, BCR108SE6433HTMA1 is listed as Obsolete.
