It integrates a 2.2 kOhm base resistor (R1) and a 10 kOhm emitter-base resistor (R2), eliminating two external passives per channel. With a collector current rating of 500 mA and a collector-emitter breakdown voltage of 50 V, it suits relay, solenoid, and LED drive circuits in industrial and consumer equipment. The 150 MHz transition frequency supports moderate-speed switching up to the low-MHz range. ## Last Buy — secure inventory now Infineon has placed the BCR555E6327HTSA1 into Last Buy status. This means the part is in its final production run — once available stock is exhausted, no further factory orders will be accepted. For any ongoing production that depends on this transistor, now is the time to secure last-time-buy quantities or qualify a pin-compatible substitute. ## What the 500 mA collector rating means for your load The 500 mA maximum collector current is the absolute ceiling for continuous DC load current. For inductive loads like relays or solenoids, derate to around 400 mA to keep junction temperature within limits given the 330 mW power dissipation budget. The 300 mV saturation voltage at 50 mA (with 2.5 mA base drive) means the transistor will drop under a third of a volt when fully on — low enough to avoid significant power loss in a 5 V or 3.3 V logic-level switching circuit.","metaTitle":"Infineon BCR555E6327HTSA1 PNP Pre-Biased Transistor, 500 mA","metaDescription":"Infineon BCR555E6327HTSA1 PNP pre-biased transistor, 500 mA Ic, 50 V Vce, 150 MHz ft, SOT-23.
