The SMF70A RQG (Reverse Quarter Geometry) is a type of Transient Voltage Suppressor (TVS) – Diode designed to protect circuits and other components from electro-static discharge (ESD) and other voltage related surges. In essence, the device acts as a current limiter that shunts or dissipates the energy generated by power transients to ground, reducing the peak voltage and protecting the downstream devices.

The SMF70A RQG is designed to dissipate over-voltage peaks with minimal influence on the operating parameters of the circuit it is protecting. The device operates in the breakdown region of the avalanche avalanche diode, in which the current flowing through the diode is limited by the high series impedance.

The SMF70A RQG is designed to replace surface-mount zener diodes, providing improved performance over a range of operating voltage and power ranges. The device has a reverse quarter geometry structure which allows it to provide superior performance as compared to a conventional zener diode. Furthermore, the structure of the device facilitates the enhancement of the current-handling capability, providing low voltage protection with higher current flow than conventional zener diodes.

The SMF70A RQG is suitable for use in applications where protection against transients is required. The device can be used to protect against ESD, power surges, over-voltage conditions, and transient voltage fluctuations. The device also provides improved protection against power component failure and component malfunctions associated with circuit designs utilizing protection diodes.

In terms of its working principle, the SMF70A RQG diode is designed to operate in the breakdown region of the avalanche avalanche diode. When the peak voltage exceeds the breakdown voltage of the diode, the input current is limited and the voltage across the diode is discharged to ground. This reduces the peak voltage, protecting the downstream electronic devices from damage.

The SMF70A RQG is designed with a built-in protection circuit that is triggered when the input voltage exceeds the break-over voltage of the diode. This enables the device to provide added protection against over-voltage conditions. Additionally, the device also features special components that enable protection against ESD current.

The SMF70A RQG is a highly reliable and efficient device, providing superior protection against ESD, over-voltage, and transient voltage fluctuations. The device is designed to fit a range of applications, offering improved performance over a wide range of operating voltage and power ranges. Furthermore, the durable construction of the device ensures that it can withstand harsh environmental conditions.
