ECG1004

ECG1004: General-Purpose NPN Silicon Bipolar Junction Transistor (BJT) housed in a standard through-hole TO-92 plastic package grid, delivering a minimum collector-emitter breakdown voltage of 25V and continuous collector currents up to 200 mA. It functions as a current-controlled amplifier with a high DC gain linearity, universally deployed as a low-power digital inverter, relay trigger, and small audio driver block.
