It integrates a 2.2 kOhms base resistor (R1) and a 10 kOhms emitter-base resistor (R2), eliminating two external passives per switching or driver stage. Collector current is rated to 500 mA with a VCEO of 50 V, and transition frequency reaches 100 MHz. Typical applications include relay drivers, small-signal switching, and logic-level interface circuits where board space is tight. ## Last-time-buy — plan your final order This part carries a Last Buy lifecycle status. That means Infineon has announced end-of-life and the final order window is open. Once the last-time-buy window closes, the only channel will be surplus or broker inventory. If this transistor is qualified on an active BOM, lock in the lifetime buy quantity now. ## 500 mA collector current — what it handles The 500 mA maximum collector current defines the load this transistor can switch. For a relay or solenoid driver, that covers many 12 V automotive and industrial loads up to about 6 W (50 V * 0.5 A derated). The saturation voltage is 300 mV at 50 mA, so dissipation in the on-state stays low for logic-level loads. The 330 mW package power limit is the binding constraint for continuous duty — at 500 mA the device must be pulsed or the ambient kept low.","metaTitle":"Infineon BCR505E6327HTSA1 NPN Pre-Biased Transistor, 500 mA","metaDescription":"Infineon BCR505E6327HTSA1 NPN pre-biased transistor in SOT-23. 500 mA collector current, 50 V VCEO, integrated 2.2 kΩ / 10 kΩ resistors.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Power - Max":"330 mW","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Last Time Buy","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR505","Resistor - Base (R1)":"2.2 kOhms","Frequency - Transition":"100 MHz","Supplier Device Package":"PG-SOT23","Resistor - Emitter Base (R2)":"10 kOhms","Vce Saturation (Max) @ Ib, Ic":"300mV @ 2.5mA, 50mA","Current - Collector (Ic) (Max)":"500 mA","Current - Collector Cutoff (Max)":"100nA (ICBO)","DC Current Gain (hFE) (Min) @ Ic, Vce":"70 @ 50mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f0026325e7ae516257149f59a76230e8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BCR505E6327HTSA1 obsolete or last time buy?","answer":"Yes, this part is in Last Buy status.
