The integrated 10 kOhm base resistor sets the drive current for typical logic-level inputs, simplifying the BOM and reducing component count. Housed in the SC-75 (SOT-416) package, the BCR 129T E6327 occupies minimal board area. Maximum power dissipation is 250 mW, so thermal derating is necessary when operating near the collector current limit at elevated ambient temperatures.","metaTitle":"Infineon BCR 129T E6327 NPN Pre-Biased Transistor, 50 V","metaDescription":"Infineon BCR 129T E6327 NPN pre-biased transistor, 50 V Vce, 100 mA Ic, 150 MHz ft, SC-75 SMD.

The suffix 'T' and 'E6327' denote the SC-75 package and tape-and-reel packaging, respectively. A direct pin-compatible equivalent would be another Infineon BCR 129 variant in the same package, such as the BCR 129T H6327 (different reel quantity). For a functional equivalent with the same 10 kOhm base resistor and 50 V / 100 mA ratings, consider the DTC114E series from ROHM or the PDTC114E series from Nexperia, but verify the package footprint (SC-75 vs SOT-23) before substitution."},{"question":"Can BCR 129T E6327 be used in switching circuits?","answer":"Yes, the BCR 129T E6327 is designed for switching applications. Its 150 MHz transition frequency and 300 mV saturation voltage at 10 mA collector current make it suitable for low-frequency load switching, relay drivers, and logic-level interface circuits. The integrated base resistor simplifies drive from a microcontroller GPIO."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BCR-129T-E6327","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BCR-129T-E6327 when reusing this data.
