Product Summary

The 2N2647 is the silicon planar unijunction transistor which has a structure resulting in lower saturation voltage, peak-point current and valley current as well as a much higher base-one peak pulse voltage. In addition, the device is much faster switch. The 2N2647 is intended for applications where a low emitter leakage current and a low peak point emitter current (trigger current) are required and also for triggering high power SCR.

Parametrics

2N2647 absolute maximum ratings: (1)Base 1 – Emitter Voltage: 30 V; (2)Base 2 – Emitter Voltage: 30 V; (3)RMS Emitter Current: 50 mA; (4)Emitter Peak Current: 2 A; (5)Total Power Dissipation: 300 mW; (6)Maximum Junction: 150℃; (7)Storage Temperature Range: -55 to +175℃.

Features

2N2647 features: (1)Low peak point current: 2μA(max); (2)Low emitter reverse current: 200nA(max); (3)Passivated surface for reliability and uniformity.
