If this transistor is on your BOM, now is the time to secure your lifetime buy or qualify a replacement — once the Last Buy period expires, the only channel will be surplus and broker stock. ## PNP pre-biased — what it saves on the board This is a PNP pre-biased transistor with integrated bias resistors: 2.2 kOhms in the base (R1) and 10 kOhms between emitter and base (R2). The pre-biased configuration eliminates the need for two external resistors in common switching applications — a direct BOM simplification that shrinks placement cost and board area. ## 500 mA, 50 V — the switching envelope Rated for 500 mA continuous collector current and 50 V collector-emitter breakdown. The 150 MHz transition frequency keeps switching losses low for PWM and relay-drive applications. ## SOT-23-3 footprint — drop-in check Supplied in the standard SOT-23-3 package (PG-SOT23), the BCR555E6433HTMA1 is footprint-compatible with the vast majority of SOT-23 small-signal transistors. If your board already has a PNP pre-biased transistor in a three-pin SOT-23 layout, this part is a direct mechanical fit — no PCB revision needed.","metaTitle":"BCR555E6433HTMA1 PNP Pre-Biased Transistor, 500 mA, 50 V","metaDescription":"Infineon BCR555E6433HTMA1 PNP pre-biased transistor, 500 mA Ic, 50 V Vce, 330 mW.

With a 50 V Vce breakdown and 500 mA collector rating, the BCR555 is well within its safe operating area for 5 V logic-level switching. The pre-biased resistors set the base current automatically — just drive the input pin with a 5 V logic signal through a current-limiting series resistor if needed."},{"question":"Is BCR555E6433HTMA1 compatible with SOT-23 footprint?","answer":"Yes. The package is listed as TO-236-3 / SC-59 / SOT-23-3, which is the standard three-pin SOT-23 footprint used across the industry.
