Introduction

TVS or Transient Voltage Suppressor diodes are electrical components designed to safeguard electronic circuits, appliances, and wire connectivity from voltage spikes. SA26-E3/73 is the type of TVS-diode designed with a wide range of applications.

Application Field

The SA26-E3/73 was designed for application circuits incorporating electrical or electronic control of DC motors. An example of this might include motor vehicles, home appliances, recreational equipment, tools, machines, and a wide variety of other products. It is also suitable for circuits such as DC to DC converters, direct current loads in the form of IGBTs, single-pole switches, and relay coils.

Working Principle

The working principle behind the SA26-E3/73 is that when voltage spikes appear they create an abnormal response in the circuit. The integrated suppression protection is designed to absorb the harmful energy created by the voltage spike, so that it cannot travel to the electronic components or cables. The SA26-E3/73 range of TVS diodes incorporate high power suppression capacity, with surge capability of up to 2000 watts.

Operational Characteristics

The SA26-E3/73 range has a wide range of operational characteristics, including high surge capability, low capacitance, low clamp level, fast response time, and low leakage current. The diodes can be used in applications with a surge capability of up to 2000 watts, operating between a range of -65℃ to + 170℃. In addition, they are designed with a high working voltage of up to 100 volts.

Basic Operation

The SA26-E3/73 operates when a voltage spike is detected. When this occurs, the diode will clamps the voltage and redirect the surge to ground. This will prevent the surge from travelling to the components or cables, thus protecting them. The SA26-E3/73 range is designed with a high clamp level of up to 116 volts, and a fast response time of just 150 ns. This makes them ideal for applications that require fast protection.

Conclusion

The SA26-E3/73 range of TVS-diodes have a wide range of applications and operational characteristics. They are designed to protect circuits, appliances, and connected cables from voltage spikes. The diodes have a high surge capability of up to 2000 watts, low capacitance, low clamp level, and fast response time. They are suitable for applications with DC motors, IGBTs, relay coils, and single-pole switches.
