Taiwan Semiconductor Co., Ltd. Single Bipolar Transistors BC550C

The BC550C is an NPN silicon transistor in a TO-92 package, rated for a collector-emitter voltage of 45 V, a collector current of 100 mA, and a power dissipation of 500 mW. The emitter-base voltage is 6 V, and the DC current gain (hFE) ranges from 420 to 800. It meets RoHS compliance and the UL 94 V-0 flammability rating for its molding compound. The device is suitable for switching applications in power supplies, adapters, and DC/DC converters. Its terminals are matte tin plated and meet J-STD-002 solderability standards and JESD 201 class 1A whisker test requirements. The package dimensions align with standard TO-92 bulk and ammo reel formats. Junction and storage temperatures range from -65°C to +150°C.
