    Looking for a circuit design

    A company is using an analog controller and the transistor listed as the oven in an oven controlled crystal oscillator. They implemented a clamper transistor to keep a voltage of 0.7V across a resistor bank and the controller indirectly controls Ic of the transistor resulting in heat...

    Looking for a circuit design

    Well the transistor listed that I want to use is a Darlington power transistor which I would like to pass 0A-just over an amp through to give me the temperature I will need. The PWM will simulate a 0-3.3VDC to the base.

    Looking for a circuit design

    Hey all, This is my first post here. I am planning to control a transistor as a heater using a microcontroller. The input to the transistor will be a 0V-3.3V PWM and I was wondering if anyone had a transistor circuit already designed. I will be using a Darlington PNP transistor, MJD117, as...
