Thyristors, commonly referred to as SCRs, are semi-conductor devices used to control electric current. SCRs are widely used in electronics and electrical equipment for various different purposes and a common type of SCR is the VVZF70-08IO7. This article will look at the application field and working principle of the VVZF70-08IO7.

A VVZF70-08IO7 SCR is a module containing two SCRs, an anti-parallel diode, and an integrated heatsink. This SCR family is designed for applications in industrial AC (alternating current) power control systems. The VVZF70-08IO7 SCR includes many features, such as fast turn-on, excellent surge capability, superior over-voltage protection, and high load current handling. VVZF70-08IO7 family members are available in voltage ratings of 600V AC, 800V AC and 1000V AC, with forward currents ranging from 20 to 50 amps and pulse current capacity of up to 150 amps.

The basic function of a thyristor is to control current. SCRs are semiconductor devices that use a triggering signal to switch on and allow current to flow, and can then be turned off with a reverse voltage. The VVZF70-08IO7 is an ideal choice for applications that need a reliable, high-performance SCR.

The VVZF70-08IO7 module uses a combination of two SCRs and a diode connected in an anti-parallel configuration. The SCRs are triggered and the diode ensures the SCRs are reverse-biased and thereby blocks forward conduction. When the SCR gate voltages reach the breakdown point and a voltage conducive to turn-on, the SCR turns on and become conducting. This is analogous to flipping a power switch and turning current on.

The VVZF70-08IO7 module can then be removed from the circuit by applying a reverse voltage of sufficient magnitude and duration. This effectively turns off the SCR and does not allow a conduction path for current. The anti-parallel diode conducts and removes the stored gate charge, and the module can then be reused.

The VVZF70-08IO7 is suitable for a range of pulse controlled applications including motor speed control, load commutation, and time delay control where devices need to switch on and off in quick succession. The integrated heatsink is a valuable addition as it dissipates generated heat and prevents thermal runaway, improving the overall reliability of the SCR.

The VVZF70-08IO7 is an ideal choice for applications needing a reliable and high-performance SCR. It has a wide range of voltage ratings, fast turn-on and excellent surge capability, superior over-voltage protection and high load current handling. The integrated heatsink ensures the device does not overheat, improving the overall reliability of the SCR.
