BC557 PNP TRANSITOR

The BC557 is a ubiquitous PNP Bipolar Junction Transistor (BJT), making it the complementary pair to the BC547, and is widely used for low-power signal amplification and switching.

Its core details are:

• Type: PNP Silicon Epitaxial Planar Transistor.

• Package:TO-92 (Through-hole).

• Maximum Collector Current (I_C):100 mA.

• Maximum Collector-Emitter Voltage V_CE:45 V.

• Maximum Power Dissipation P_D:500 mW.

• DC Current Gain h_FE: High gain, typically 110 to 800

It is mainly used in complementary circuits (with the BC547), for small signal amplification, and as a general-purpose low-power switch
