ON Semiconductor MMQA6V8T1 Series Quad Monolithic Zener Voltage Regulators

The MMQA6V8T1 series from ON Semiconductor represents a line of high-quality, quad monolithic Zener voltage regulators designed for a wide array of applications requiring precise voltage regulation and noise suppression. These devices are packaged in a compact SOT-353 surface mount package, providing a space-saving solution suitable for high-density circuit boards.

Each MMQA6V8T1 Zener voltage regulator consists of four Zener diodes that are internally connected in common anode configuration. This design enables the device to provide excellent power dissipation characteristics with a total power dissipation of 225 mW. The series is characterized by its tight voltage tolerance, ensuring reliable and consistent performance across the operating range.

The Zener voltage for the MMQA6V8T1 series is specified at 6.8 volts, making it an ideal choice for applications that require a stabilized voltage in this range. The device's Zener impedance is low, which contributes to its ability to maintain a stable voltage under varying load conditions. This feature is particularly beneficial in applications where load fluctuations are common, such as in power management circuits.

ON Semiconductor's MMQA6V8T1 series is designed to withstand electrostatic discharge (ESD) events, featuring an ESD rating of ≥ 16 kV (Human Body Model). This robust protection makes the devices suitable for use in environments where ESD events are a concern, helping to prevent damage to the Zener diodes and ensuring the longevity of the application.

The series is also characterized by its wide operating temperature range, from −55°C to +150°C, allowing for reliable operation in extreme environments. This temperature resilience, combined with the small package size, makes the MMQA6V8T1 series a versatile choice for various applications, including consumer electronics, automotive systems, and industrial controls.

ON Semiconductor's commitment to quality ensures that the MMQA6V8T1 series Zener voltage regulators meet the stringent requirements of modern electronic devices. With its precise voltage regulation, compact footprint, and robust protection features, the MMQA6V8T1 series is an excellent choice for designers seeking to enhance the performance and reliability of their electronic systems.
