MMO90-16IO6

Thyristors - SCRs - Modules

The MMO90-16IO6 is a type of thyristor (Silicon Controlled Rectifiers or SCR) module that is well-suited in many applications. It is a part of Morrow’s Family-M modules series and is designed for space-sensitive users. It is a 6-pin module that features an industry-standard DO-214AA-C form that allows for peak reverse voltage rating of up to 1500 V. Its insulated type design also secures a safe and reliable operation and its small size, together with its wide junction temperatures specify it for use in harsh environmental conditions.

The MMO90-16IO6 is suitable for use of variety of applications that require efficient control and high-inrush current capability with high voltage ratings. Its peak blocking voltage of up to 1200 VDC and its I2t of up to 36 A²/sec qualifies it for use in converters and variable speed drives. It is also ideal for use in many power and industrial control applications such as welders, soft starters, AC variable speed drives, and lighting, electronics and telecommunications circuits. Furthermore, the device offers an excellent turn-on and turn-off time enabling it to switch high inrush currents in demanding applications.

Working Principle

The MMO90-16IO6 is a type of SCR (silicon-controlled rectifier) that works with bi-directional control of unidirectional power flow. It is composed of four layers of alternating semiconductor and metal that acts as a rectifier. The device is composed of an anode, cathode and gate. In order for the device to conduct current, the gate must be activated first. When the gate is activated, with the applied forward voltage, current will begin to flow from the anode to the cathode. The device will remain in an on-state until the anode-cathode voltage drops to a certain level. This makes the device useful in power control applications as its conduction current is related to the voltage and can be controlled. Furthermore, the device can be controlled directly with a current control signal.

The MMO90-16IO6’s is also considered to efficiency due to its low forward voltage drop of only 0.35 V when it conducts, its small size, and its low turn-on and turn-off times. This makes the device useful in many applications that require efficient control.

Conclusion

In summary, the MMO90-16IO6 is a low-profile SCR module that is suited for many applications including converters, industrial control, welders, soft starters, AC variable speed drives, and lighting, electronics and telecommunications circuits. Its bi-directional current control can be adjusted with a gate current control signal, making it ideal for use in power control applications. The device’s low forward voltage drop, small size, and low turn-on and turn-off times also make it an efficient device for many applications.
