The ON Semiconductor MMQA20VT1 series represents a range of high-quality, quad monolithic common anode Transient Voltage Suppressors (TVS) diodes designed to protect voltage sensitive components from destruction or degradation. These devices are housed in a compact SC-74 package and are optimized for use in a variety of applications where dual or quad line protection is needed in a small footprint.

Key Features

• Peak Power Dissipation: Each device in the series is capable of handling 200 Watts of peak power dissipation for an 8/20μs waveform, which ensures robust protection against high-energy transients.
• Stand-Off Voltage: The MMQA20VT1 series offers a stand-off voltage of 20V, providing a stable protective barrier for sensitive circuits operating at or below this voltage level.
• Low Leakage Current: These diodes are designed with a low leakage current of less than 1μA, which is beneficial for maintaining energy efficiency in the protected circuit.
• Common Anode Configuration: The quad diode array's common anode configuration simplifies PCB layout and reduces the number of components required for bidirectional protection.
• SC-74 Package: The small SC-74 package is ideal for space-constrained applications, allowing designers to include protection in designs without compromising on size or performance.
