Each transistor has a base resistor (R1) of 10kΩ and an emitter-base resistor (R2) of 47kΩ, so you get a complete switching stage without external resistors. The collector-emitter breakdown is rated at 50V, and each transistor can handle up to 100mA collector current. With a transition frequency of 200MHz, it works well for low-frequency switching and signal conditioning up to the low-MHz range. ## Where you would use it This dual transistor is a natural fit for space-constrained boards where you need two independent PNP switching stages — think inverter logic, relay drivers, or level shifters in 5V and 3.3V systems. The pre-biased resistors simplify the base drive: you just pull the base low through a microcontroller GPIO or an open-collector output, and the transistor turns on. The SOT-363 footprint (PG-SOT363-PO) is a standard 6-pin SC-88 layout, so it drops onto existing pads for similar dual transistors. ## Lifecycle reality — this part is obsolete The BCR185SE6327BTSA1 carries an Obsolete product status. There is no official successor listed in the Infineon portfolio for this exact pre-biased dual PNP configuration, so a pin-compatible replacement search is the practical next step. The 300mV Vce saturation at 500µA base current and 10mA collector current tells you the on-state voltage drop is low enough for 3.3V logic interfacing without wasting headroom. The DC current gain minimum of 70 at 5mA collector current and 5V Vce means the transistor has decent gain even at moderate currents — useful when you are driving a relay coil or an LED string where the base drive comes from a weak GPIO. The 250mW power dissipation limit per package (both transistors combined) sets a thermal ceiling: at 100mA per transistor with a 2V drop, you are at 200mW total, leaving 50mW margin. Keep the ambient temperature and PCB copper area in mind if you push both channels near the limit.","metaTitle":"BCR185SE6327BTSA1 dual PNP pre-biased transistor, 50V 100mA","metaDescription":"Infineon BCR185SE6327BTSA1 dual PNP pre-biased transistor array, 50V Vce, 100mA Ic, 200MHz ft, SOT-363.","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 PNP - Pre-Biased (Dual)","lifecycle_stage":"eol_hot","Resistor - Base (R1)":"10kOhms","Frequency - Transition":"200MHz","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/66701357389c2165763e8a31e7820059.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BCR185SE6327BTSA1 obsolete?","answer":"Yes, the BCR185SE6327BTSA1 is listed as Obsolete.
