The 1.5KE62AHA0G TVS diode is an advanced integrated surge protection device designed to serverelectronics applications from potential faults. It protects electronic equipment, circuits and systemsfrom high voltage transient surges and over-voltage spikes. The 1.5KE62AHA0G TVS diode offersa wide range of features, including a high peak pulse power capability, suppression of high dV/dt ratesand high response time to current transient conditions.

The 1.5KE62AHA0G TVS diode is designed primarily for protection against Electrical Transientscaused by switching operations and transients induced by switching in other equipment. The protectionis provided by its ability to clamp large transient energy. It’s designed for AC Line overvoltageprotection against voltage transients caused by lightning. It’s also suitable for short duration load-dopulses for motors and transformers.

The 1.5KE62AHA0G application field mainly includes the following areas:

• Electronic systems
• Power supplies
• Power conversion equipment
• Communication lines
• Telecommunication systems
• Automotive electronics

The protection circuits for these devices are most commonly fabricated with conventional bipolar transistors.When exposed to a surge current pulse, the transistors are forced into the ON state, which increases the voltage across the device. When the ON voltage exceeds the breakdown voltage of the device, the current will rapidly increase. Once the current reaches a certain limit, the transistor will switch back to its initial OFF state, thus providing effective surge protection.

Besides the bipolar surge protection circuit, the 1.5KE62AHA0G also utilizes Metal Oxide Varistors (MOVs). MOVs, also known as Varistors, are voltage-dependent components used to protect circuits from transient overvoltage conditions. When exposed to a surge current pulse, the MOVs will rapidly clamp or limit the voltage by behaving like a short circuit. The voltage will return to its previous level as soon as the surge current pulse passes.

In addition to the bipolar protection circuit and MOVs, the 1.5KE62AHA0G is also equipped with an internal temperature sensing unit. The sensing unit allows the device to automatically shut down in the event of an over-temperature condition. This is especially useful in applications where excessive temperatures may cause damage to sensitive components.

Finally, the 1.5KE62AHA0G TVS diode also utilizes a gas-tube absorber to provide protection against Electrostatic Discharge (ESD). The gas-tube absorber is designed to provide an additional layer of protection against ESD events by absorbing the energy of the discharge.

The 1.5KE62AHA0G is an advanced integrated surge protection device that offers a wide range of features for protecting electronic equipment, circuits, and systems. The device offers a high peak pulse power capability, suppression of high dV/dt rates, and high response time to current transient conditions. The range of applications include electronic systems, power supplies, power conversion equipment, communication lines, telecommunication systems, and automotive electronics. The protection circuits utilized consist of bipolar transistors, MOVs, an internal temperature sensing unit, and a gas-tube absorber.
