Introduction to TVS- Diodes

TVS - Diodes have become an increasingly popular device for protecting powered peripherals from high voltage transients. TVS diodes provide a passive protection barrier between the circuitry of the peripheral device and the electrical noise or high voltage pulses associated with high-voltage transients. In this article we will explore the application of a specific TVS diode, the 3KASMC13AHE3_B/H, including its working principle and application field.

Working Principle of the 3KASMC13AHE3_B/H

The 3KASMC13AHE3_B/H is a Transient Voltage Suppressor (TVS) diode that uses avalanche breakdown to protect circuits from excessive voltage transients. Avalanche breakdown occurs when the electric field within the device exceeds the electric field that allows a standard p-n junction diode to work. When this happens, a very large current is generated, which allows the TVS diode to act as a clamp that dissipates dangerous current. The 3KASMC13AHE3_B/H is designed around the principle of avalanche breakdown, so it can be used in many different applications. For example, it can be used in telecom and data applications to provide protection from high voltage transients.

Characteristics of the 3KASMC13AHE3_B/H

The 3KASMC13AHE3_B/H is designed for between-line, AC and DC applications. It has a nominal break-down voltage of 7.0V and a maximum operating voltage of 13.0V. It has a maximum peak pulse current capability of 3000A and a maximum clamping voltage of 14.7V. The device also has a low leakage current of 0.1μA, a capacitance of 0.27pF, and an operating temperature range of between -40°C and +125°C.

Application Field of the 3KASMC13AHE3_B/H

The 3KASMC13AHE3_B/H is suitable for use in telecommunications and consumer electronics, especially in the automotive sector. It is also suitable for use in power supplies, such as switching mains supplies, and part of digital networks, such as in hybrid coax/fiber networks. In industrial applications, the device can be used to protect industrial instruments against ESD, EMI, and electrostatic field transients. It can also be used in devices and equipment that need protection from electrical surges.

Conclusion

The 3KASMC13AHE3_B/H is a versatile TVS diode that can be used in a wide range of applications. It is designed for use in between-line, AC and DC applications and has a wide operating temperature range and low leakage current. It can be used to protect telecom and data applications, as well as automotive electronics, industrial instruments, and other devices and equipment from high transients.
