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.","metaTitle":"BCR133E6393HTSA1 NPN Pre-Biased Transistor, 50V, 100mA","metaDescription":"Infineon BCR133E6393HTSA1 NPN pre-biased transistor, 50V Vce, 100mA Ic, 10kOhm R1/R2, 130MHz ft.
