TVS - Diodes - MAPLAD36KP70A application field and working principle

Transient Voltage Suppressor (TVS) diodes are used to protect electrical & electronic devices from potential damage from transient voltage surges. TVS diodes absorb the excess voltage and absorb it, dissipating the energy as heat. They can work together with other protection systems, like fuses and circuit breakers, to guard against various levels of possible voltage abnormalities.

The MAPLAD36KP70A TVS diode is a component specifically designed to protect circuits against the damaging effects of transient voltages resulting from electrostatic discharge (ESD), electrical fast transients, surge, and other environmental transients. This module can be used in both commercial and automotive applications.

The MAPLAD36KP70A TVS diode has a unique, highly tolerant design. It is designed to work in environments where high current and high voltage transient voltage surges exist. It is the preferred component to protect devices when handling very large transients in quickly changing conditions.

In the MAPLAD36KP70A TVS diode, two MOSFETs and a zener diode are connected in series as the active components. The MOSFETs both serve to reduce the reverse bias voltage across the zener diode, causing the device to be biased in the breakdown or "clamping" region. During the exposure to a transient voltage, the current flow produces a voltage drop across the MOSFETs, thus ensuring the voltage is clamped at the breakdown voltage of the zener diode. This clamps the voltage of the system and reduces the probability of damage to the electrical and electronic circuitry from the transient surge current.

When the incident voltage is higher than the breakdown voltage, the MOSFETs start to conduct and limit the voltage across the zener diode to the breakdown voltage, thus providing protection to the circuitry from the high voltage surge. When the surge current is discharged, the MOSFETs switch off and the circuit returns to its quiescent state.

The dielectric strength of the MAPLAD36KP70A TVS diode is superior to most other devices available. It can withstand a maximum working voltage of 6.8 volts and its surge current capability is 6k A (8 20 microseconds). This high surge current capability is very useful in protecting devices that are exposed to repeated transients. The high surge current capability of the MAPLAD36KP70A TVS diode also helps reduce the thermal stress on the protection devices.

The MAPLAD36KP70A TVS diode is a very reliable and robust device that provides protection against various levels of transient voltage disturbances. Its wide range of applications makes it an ideal solution for many applications. It is cost-effective and widely available for commercial and automotive applications.
