When both the emitter and collector junctions are in a positive bias state in the saturation region,
When the collector is open and a specified reverse voltage is applied between the emitter and base,
The cut-off frequencies f β and f α are 0.707 times the frequency when β drops to low frequencies
The transistor is commonly represented by "Q" and a number in circuits, for example
Shenzhen Aoweisi Technology Co., Ltd. acts as an agent for AUK Korean optoelectronic diodes,
