TVS diodes are essential components for a range of electronic circuits, providing protection to sensitive components or circuits from transient voltages and currents. One of the more general-purpose TVS diodes, which can be used across a variety of circuits with a wide range of applications, is the SMAJ5.0HE3/61. This article will outline the application field of the SMAJ5.0HE3/61, as well as provide a brief overview of its working principle.

The SMAJ5.0HE3/61 is a low capacitance transient voltage suppressor (TVS) diode. It is designed for line-to-ground or line-to-line protection in automotive, computer, industrial systems, and communication equipment. The SMAJ5.0HE3/61 is configured with bi-directional bidirectional protection characteristics, and can be used to clamp transient spikes or surges of up to 5.0kV.

Due to its small size and low capacitance, the SMAJ5.0HE3/61 is ideal for use in situations involving tight spaces. For example, a 17mm radius allows for easy installation with no limiters in extremely small holes. It has a low clamping voltage, typically around 19V, and can protect circuits from overvoltages up to 5.0kV.

When operating normally, the SMAJ5.0HE3/61 is designed to be non-conductive, allowing no current to pass through until it detects a voltage spike or surge. When a transient voltage is greater than the breakdown voltage of the SMAJ5.0HE3/61, the diode becomes conductive. This allows any excess current to be diverted away from the circuit, thus protecting the components or circuitry from damage.

The SMAJ5.0HE3/61 utilizes a series circuit to protect against transients, with the working principle of the SMAJ5.0HE3/61 being similar to other TVS diodes. In operation, it consists of two back-to-back diodes, each with its own reverse breakdown voltage. When the voltage across the two diodes is greater than the sum of the breakdown voltages, a current will flow through the diode, allowing the transient voltage to be suppressed from the protected circuitry.

The speed of the SMAJ5.0HE3/61 is also important for providing effective protection. Its response time is in the range of 25 to 75 nanoseconds, which ensures that transients will be clamped and diverted away from the protected circuit before any damage can occur.

In conclusion, the SMAJ5.0HE3/61 is a versatile and reliable TVS diode capable of protecting a wide variety of circuits from transient voltages and currents. It is a popular choice for automotive, computer, industrial systems, and communication equipment as it can provide bi-directional protection, is small in size, and has a low capacitance. Its working principle utilizes a series circuit with two back-to-back diodes, each with its own reverse breakdown voltage, allowing transients to be clamped in a fast and effective manner.
