CR5AS 5A 400V Silicon Controlled Rectifier (SCR) fast recovery diode It comes with a receiverThe CR5AS is a Silicon Controlled Rectifier (Thyristor) commonly used in medium power control and rectification. It is essentially a Shockley diode with an extra terminal added. This extra terminal is called the gate, and it is used to trigger the device into conduction (latch it) by the Applications of a small voltage. To trigger, or fire, an SCR, the voltage must be applied between the gate and cathode, positive to the gate and negative to the
