Introduction

Transient Voltage Suppressor (TVS) diodes are special types of diodes used to protect electronic circuits from transients in the form of overvoltage, such as spikes or surges. They are an essential component in protecting circuit integrity when designing a circuit board, and are used in a variety of applications. One of the most widely used TVS diodes is the SMBJ11C.

SMBJ11C Basics

The SMBJ11C is a bi-directional TVS diode that is available in a variety of breakdown voltages ranging from 12 to 175 V. It is a surface mount diode that is capable of handling high peak pulse currents up to 600A, with an 8/20 µs pulse, while presenting low leakage current at off-state conditions. It features an Ultra-Fast response time of 10 ns typical, and allows for a working range from -55°C up to +150°C. Its maximum peak power clamping at 1.6 KW meets the needs of most power, telecom and automotive applications.

Application Field

The SMBJ11C is most commonly used in automotive, power, and telecom applications. In automotive applications, it is used to protect circuits from load dump conditions in order to ensure the safety of the vehicle and its occupants. In power applications, it is used to provide lightning strike protection, as well as to protect against overvoltage and undervoltage transients. In telecom applications, it is used to protect against overvoltage transients for power, ground, and data line circuits.

Working Principle

The working principle of the SMBJ11C is based on the principle of avalanche breakdown. When the reverse voltage applied to the diode exceeds the breakdown voltage, the diode will avalanche and allow a large amount of current to flow. This sudden flow of current dissipates the excess energy of a transient as heat, thus protecting the circuit from the damages caused by the transient. When the transient is over, the diode will quickly recover, and the circuit can then continue to operate as normal.

Conclusion

The SMBJ11C is a versatile and reliable TVS diode that is used for a range of applications, including automotive, power, and telecom circuits. It features an Ultra-Fast response time of 10 ns typical, and is capable of handling high peak pulse currents up to 600A. Its maximum peak power clamping at 1.6 KW allows it to be used for a variety of applications, ranging from lightning strike protection to protecting against load dump transients.
