Renesas Electronics Corporation FA4A4P(0)-T1B-A

The FA4xxx series consists of resistor-built-in NPN silicon transistors in an SC-59 package, designed for general-purpose switching applications. Each variant features built-in base-emitter and base-collector resistors, with a maximum collector-to-emitter voltage of 50 V, collector current of 0.1 A (DC), and total power dissipation of 0.2 W. The junction temperature rating is 150 °C, and the storage temperature ranges from -55 °C to +150 °C. The FA4A4P variant specifies emitter-to-base voltage of 5 V, with base-emitter resistor of 10.0 kΩ and base-collector resistor of 47.0 kΩ. The package dimensions are 2.9 mm ± 0.2 mm in length, 1.1 to 1.4 mm in width, and 0.95 mm in height. The part is classified as 'Standard' quality grade, intended for use in computers, office equipment, communications devices, and consumer electronics.
