Transistor 2SC2061 NPN 80V 0.7A

The Transistor 2SC2061 is an NPN bipolar junction transistor rated at 80 V and 0.7 A. It sits between small-signal transistors and larger power devices, so it suits driver stages, audio amplifier circuits and switching relays, LEDs and other small loads. The 2SC prefix is the Japanese (JIS) code for NPN transistors, and this part is a handy spare when repairing equipment that uses it.

What's in the Box

• 1 × 2SC2061 NPN transistor

Tip: When switching a relay or other coil, fit a flyback diode such as the 1N4007 across it to protect the transistor, and use a base resistor (around 1 kΩ from a 5 V pin) to limit the base current. Check the emitter, collector and base pins in the datasheet before fitting.
