Product details

What this pre-biased NPN does on the board

The BCR 133F E6327: The Infineon BCR 133F is an NPN pre-biased transistor in a SOT-723 surface-mount package. It integrates two 10 kOhm resistors — one in series with the base, one between base and emitter — so you drop the two external passives from the BOM for low-side switching, relay drivers, or logic-level interface circuits. Collector-emitter breakdown is rated at 50 V, continuous collector current at 100 mA, and the transition frequency hits 130 MHz.

Sourcing this part now that it's obsolete

Infineon lists the BCR 133F as Obsolete. That means the factory line has stopped, and the only available stock sits in independent distribution or surplus channels. No official replacement part number is published by Infineon for this exact order code. If you need a drop-in pre-biased NPN in SOT-723 with 10 kOhm resistors, the closest functional equivalent would be another manufacturer's part with the same resistor values and package — but pin compatibility must be verified against your board layout.

Frequently asked questions

Where can I buy BCR 133F E6327 available via RFQ confirmation?

BCR 133F E6327 is obsolete and not available through franchised distribution. Submit a request for current availability and pricing — we confirm both at quote time.

Is BCR 133F E6327 obsolete and what is the replacement?

No official replacement order code has been published. A functional equivalent would need the same NPN pre-biased topology with 10 kOhm base and emitter-base resistors in SOT-723 — but you must verify pin compatibility against your PCB.
