It handles a maximum collector current of 500 mA and a collector-emitter breakdown voltage of 50 V, with a transition frequency of 150 MHz. Typical applications include relay drivers, lamp drivers, and general-purpose load switching where board space is tight. ## Last Buy — final procurement window This part carries a Last Buy lifecycle status, meaning the manufacturer has announced end-of-life and is accepting final orders for a limited time. Once the last-time-buy window closes, availability will shift to surplus and broker channels. If your BOM still specifies this order code, secure inventory now or qualify a replacement before the cutoff. ## Sourcing and fit for the BOM For a BOM line using this pre-biased PNP, the key fit parameters are the 50 V VCEO and 500 mA Ic rating — sufficient for low-side switching of small relays, solenoids, or indicator loads in 12 V and 24 V industrial systems. The integrated bias resistors (2.2 kOhm base, 2.2 kOhm emitter-base) set the turn-on threshold and eliminate two external passives, saving placement cost.","metaTitle":"BCR553E6327HTSA1 PNP Pre-Biased Transistor, 50 V, 500 mA","metaDescription":"BCR553E6327HTSA1 PNP pre-biased transistor, 50 V VCEO, 500 mA Ic, 150 MHz ft, SOT-23.","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)","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":"PNP - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR553","Resistor - Base (R1)":"2.2 kOhms","Frequency - Transition":"150 MHz","Supplier Device Package":"PG-SOT23","Resistor - Emitter Base (R2)":"2.2 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":"40 @ 50mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.0736","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.infineon.com/dgdl/bcr553.pdf?folderId=db3a30431428a373011440769fd70304&fileId=db3a30431428a37301144080e0fd030b","sourceUrl":null},"ai":{"faq":[{"question":"Is BCR553E6327HTSA1 obsolete?","answer":"This part is in Last Buy status, meaning the manufacturer has initiated end-of-life.
