The 1.5SMC300AHE3_A/I is a TVS diode with a snap-acting mechanism, designed to protect sensitive electronic components from transients. It is commonly used in industrial, telecom, automotive, home appliance, and consumer electronics applications where it helps to protect sensitive electronic components from transients, such as electro-static discharges (ESD) and electrical fast transients (EFT). In this article, we will look at the application field and working principle of the 1.5SMC300AHE3_A/I.

Application Field

The 1.5SMC300AHE3_A/I is designed for use in surge protection applications in industrial, telecom, automotive, home appliance, and consumer electronics applications. It is especially effective at limiting ESD pulses and EFT pulses that occur during a surge event. It is suitable for protection of up to 10kW loads, typically at an efficiency of 90%.

The 1.5SMC300AHE3_A/I is constructed with a metal oxide varistor (MOV) and a snap-acting mechanism. The MOV acts to dissipate potential transients, while the snap-acting mechanism is designed to turn the device on when a surge is detected. This snap-action occurs in less than 1 nanosecond, providing fast reaction times and reliable protection.

Working Principle

The 1.5SMC300AHE3_A/I is designed to provide protection against electrical transients, such as ESD and EFT. It works by using a MOV to dissipate potential transients, and a snap-acting mechanism to quickly turn the device on when a surge is detected.

In operation, the MOV absorbs the energy of the transient and the snap-acting mechanism quickly turns the device on. Once the surge is absorbed, the MOV will reset and the 1.5SMC300AHE3_A/I will be ready for the next transient.

The 1.5SMC300AHE3_A/I offers a wide range of protection, with a surge current rating of up to 5kA (CW) at 10/1000μs and a surge voltage rating of up to 650V. In addition, the device is designed to operate across a wide range of temperatures, from -55°C to 150°C.

Conclusion

The 1.5SMC300AHE3_A/I is a TVS diode designed for protection of sensitive electronic components from transients, such as ESD and EFT. It is designed with a MOV and a snap-acting mechanism, which helps it to quickly turn on in response to a transient. The device offers excellent protection, with a surge current rating of up to 5kA and a surge voltage rating of up to 650V. This makes it a great choice for surge protection in a wide range of industrial, automotive, and consumer electronic applications.
