Each transistor integrates a 10kOhm base resistor (R1) and a 10kOhm emitter-base resistor (R2), eliminating two external resistors per channel. This saves board space and reduces pick-and-place cost in high-volume designs where you need two low-current switching channels. Rated for a collector-emitter breakdown of 50V and a maximum collector current of 100mA, with a power dissipation ceiling of 250mW. The 130MHz transition frequency suits switching applications up to low-MHz range — think relay drivers, logic-level interface buffers, or LED indicator switching in industrial controls and consumer appliances. Infineon lists the BCR133SE6433BTMA1 as obsolete. That means no further factory production — no last-time-buy window remains. The base product number is BCR133S, so any official replacement would share that prefix. No successor order code appears on the lifecycle record. If you need a drop-in alternative, a dual NPN pre-biased transistor in SOT-363 with matching 10kOhm / 10kOhm resistor values is the parametric match to search for — but verify the pinout against your layout before committing a board spin. ## Package and storage notes The small 6-pin footprint fits tight layouts.","metaTitle":"Infineon BCR133SE6433BTMA1 Dual NPN Pre-Biased Transistor","metaDescription":"Infineon BCR133SE6433BTMA1 dual NPN pre-biased transistor, 50V Vce, 100mA Ic, 250mW, 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 NPN - Pre-Biased (Dual)","lifecycle_stage":"eol_hot","Base Product Number":"BCR133S","Resistor - Base (R1)":"10kOhms","Frequency - Transition":"130MHz","Supplier Device Package":"PG-SOT363-PO","Resistor - Emitter Base (R2)":"10kOhms","Vce Saturation (Max) @ Ib, Ic":"300mV @ 500µA, 10mA","Current - Collector (Ic) (Max)":"100mA","Current - Collector Cutoff (Max)":"-","DC Current Gain (hFE) (Min) @ Ic, Vce":"30 @ 5mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/da5fc9ead9e2b22151fb962c98fc84f4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BCR133SE6433BTMA1/alternatives.json"},"ai":{"faq":[{"question":"Is BCR133SE6433BTMA1 obsolete?","answer":"Yes, Infineon lists the BCR133SE6433BTMA1 as obsolete.
