This integration saves one or two external resistors per channel on the PCB, which matters when you are populating a dense board or trying to reduce pick-and-place cost on a high-volume design. The part is rated for 50 V collector-emitter breakdown and 100 mA continuous collector current, with a transition frequency of 150 MHz — suitable for low-speed switching, relay and solenoid drivers, and general-purpose interface circuits where the load current stays under 100 mA. It comes in a standard SOT-23-3 surface-mount package (Infineon designates it PG-SOT23). Infineon lists the BCR 135 B6327 as obsolete. For a sustainment program or a repair that needs this exact order code, the supply path is the independent distribution market — surplus inventory, overstock, or last-time-buy leftovers. ## Saturation voltage and gain — the switching performance numbers The Vce saturation is specified at 300 mV maximum with a 500 µA base drive and 10 mA collector current — a clean, low-drop switch for logic-level loads. DC current gain (hFE) is a minimum of 70 at 5 mA collector current and 5 V Vce, which is typical for a pre-biased part where the integrated resistors set the base drive. The 100 nA maximum collector cutoff current (ICBO) means leakage is negligible in off-state, so it will not pull a weakly driven output low.","metaTitle":"BCR 135 B6327 NPN Pre-Biased Transistor, 50 V, 100 mA","metaDescription":"Infineon BCR 135 B6327 NPN pre-biased digital transistor. 50 V Vce, 100 mA Ic, 150 MHz ft.

For a form-fit-function substitute, look for another NPN pre-biased digital transistor in SOT-23 with a 10 kΩ base resistor and 47 kΩ base-emitter resistor, rated for at least 50 V and 100 mA. The BCR 135 series includes several variants with different resistor ratios; verify the resistor values match your circuit's base drive requirements before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BCR-135-B6327","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BCR-135-B6327 when reusing this data.
