This is a board-space play: one six-pin package replaces two discrete transistors and four resistors, which matters when you are routing a dense gate-driver bank, a relay coil interface, or a PLC output stage. The 50 V collector-emitter breakdown and 100 mA continuous collector rating cover typical 24 V industrial logic loads, small relays, and indicator LEDs. Maximum power dissipation is 250 mW for the dual package — derate from that when both channels conduct simultaneously at elevated ambient. Transition frequency of 100 MHz is ample for the switching speeds these pre-biased parts are used for — think a few kilohertz to a few hundred kilohertz, not a switching regulator. That is not a last-time-buy yet, but it signals the part is on a phase-out trajectory. For an existing production line already using this order code, NRND means you should evaluate the last-time-buy horizon and secure bridge inventory through independent distribution while the part is still widely available on the spot market. ## Package and footprint fit The part ships in a PG-SOT363-PO package — Infineon's designation for a standard 6-pin SOT-363 (SC-88) surface-mount case. The SOT-363 footprint is common and shared across many dual small-signal transistors and pre-biased arrays, so a PCB land pattern designed for a generic SOT-363 will accept this part. Supplied in Tape & Reel, consistent with automated pick-and-place assembly.","metaTitle":"Infineon BCR148SH6433XTMA1 Dual NPN Pre-Biased Transistor","metaDescription":"Infineon BCR148SH6433XTMA1 dual NPN pre-biased transistor. 50 V VCEO, 100 mA Ic, 250 mW.

Check the base product number BCR148 for available suffixes. Outside the family, any dual NPN pre-biased transistor array in SOT-363 with 47 kΩ base and emitter-base resistors is a functional equivalent, but verify pinout — not all SOT-363 pre-biased arrays share the same internal configuration."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BCR148SH6433XTMA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BCR148SH6433XTMA1 when reusing this data.
