That means the manufacturer has scheduled end-of-production; remaining stock is finite and being drawn down. If you're repairing a board that uses this part, the scorch mark tells you which transistor failed — but the real question is whether you can get a genuine replacement before the channel dries up. ## What the bias resistors do for your circuit The integrated bias network — a 4.7 kΩ base resistor (R1) and a 47 kΩ emitter-base resistor (R2) — saves two external passives and shrinks the footprint to a single SOT-23. The R1/R2 ratio sets the turn-on threshold: with a 5 V logic drive, the base current is limited by R1, while R2 provides a bleed path to keep the transistor off when the drive is low. This is the same internal divider used across the BCR116 family, so if you're cross-referencing a replacement, those resistor values are the first thing to match. ## Ratings that decide the fit Collector-emitter breakdown is 50 V, and continuous collector current is rated 100 mA — comfortable for low-side switching of relays, LEDs, or small solenoids in 12 V or 24 V industrial logic. The 150 MHz transition frequency means it handles PWM into the low-MHz range without noticeable storage-time lag. Maximum power dissipation is 200 mW in the SOT-23 package — derate if ambient exceeds 25 °C or if the board has poor airflow.","metaTitle":"BCR116E6433HTMA1 NPN Pre-Biased Transistor, 50V 100mA","metaDescription":"BCR116E6433HTMA1 NPN pre-biased transistor with integrated 4.7 kΩ base and 47 kΩ emitter-base resistors. 50 V, 100 mA, 150 MHz fT.","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":"200 mW","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Not For New Designs","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR116","Resistor - Base (R1)":"4.7 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":"$0.0454","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BCR116E6433HTMA1/alternatives.json"},"ai":{"faq":[{"question":"Is BCR116E6433HTMA1 obsolete?","answer":"It carries a Last Buy lifecycle status, meaning the manufacturer has announced end-of-production.
