Product details

Built-in biasing saves two passives

The Infineon BCR133E6393HTSA1 is an NPN pre-biased transistor that integrates two 10 kOhm resistors — one in series with the base (R1) and one between base and emitter (R2). That means a single SOT-23-3 part replaces the discrete transistor plus two external resistors, cutting placement cost and board area in low-current switching or driver stages where you need a controlled on/off threshold. With a 50 V collector-emitter breakdown and 100 mA continuous collector current, it handles typical 5 V to 24 V logic-level loads — relay coils, indicator LEDs, small-signal level shifters — without extra biasing components.

Last Buy — plan your final order

This part carries a Last Buy lifecycle status, meaning Infineon has scheduled its end of production. If this transistor is on your BOM, now is the time to secure lifetime buy quantities or qualify a drop-in alternative before the window closes.

Frequently asked questions

Is BCR133E6393HTSA1 being discontinued?

Yes, BCR133E6393HTSA1 is in Last Buy phase. Infineon has marked it for discontinuation, so final procurement should be arranged promptly.

What are the resistor values (R1/R2) of BCR133E6393HTSA1?

Both the base resistor (R1) and the emitter-base resistor (R2) are 10 kOhms each, giving a predictable input threshold and turn-off behavior without external components.

What is a direct equivalent or replacement for BCR133E6393HTSA1?

For a cross-reference, compare other NPN pre-biased transistors with 10 kOhm R1/R2 in SOT-23-3 — the built-in resistor ratio is the critical parameter for threshold matching. Submit an RFQ for assistance identifying a suitable alternate.
