The FMMT458 is a 400V NPN High Voltage Transistor in a SOT23 package. It offers a high continuous collector current of 225mA, a peak pulse current of 1A, and 500mW power dissipation. This transistor exhibits excellent hFE characteristics up to 100mA and is available as a complementary PNP type (FMMT558). It is designed to be totally lead-free, fully RoHS compliant, and halogen and antimony-free, making it a "Green" device. An automotive-compliant version (FMMT458Q) is also available under a separate datasheet.
