TVS-Diodes are a type of voltage protection component used to protect electronic devices and circuits from overvoltage and electrostatic discharge (ESD). The SMBJ16CD-M3/H is a Transient Voltage Suppressor device used to protect sensitive electronic components from short duration voltage transients that may exceed their normal operating voltage.

SMBJ16CD-M3/H devices are qualified under the requirements of the international safety standards UL 1414 and CSA 22.2No. 223. They feature a very fast response time that is critical for protecting sensitive circuits. The SMBJ16CD-M3/H is designed to meet a maximum clamping voltage of 16V, with an operating junction temperature ranging from -55°C to +155°C.

SMBJ16CD-M3/H Transient Voltage Suppressor Diodes are widely used in consumer and automotive electronics as well as in communication equipment, medical equipment, industrial equipment and more. They are used to protect delicate electronics from voltage transients such as electrostatic discharge (ESD), electrical fast transients (EFT), and line transients. The device’s fast response time is critical to protecting delicate components from these transients, which can cause immediate damage or even permanent performance degradation.

Aside from providing overvoltage protection, SMBJ16CD-M3/H devices also offer positive temperature coefficient (PTC) and thermistor protection from short-term transients and long-term overloads. They are low-profile, thermally-stable components that operate on a wide operating range. This makes the device ideal for applications with high temperature variations or where space is at a premium.

The operating principle of the SMBJ16CD-M3/H Transient Voltage Suppressor device is based on the avalanche breakdown principle. When a forward current is applied to the device, the voltage between the anode and cathode terminals increases until it reaches a point known as the avalanche breakdown voltage, at which point the p-n junction begins conducting current. The breakdown voltage is determined by the doping concentrations of the p-n junction, which varies from part to part.

In addition to providing ESD and overvoltage protection, the SMBJ16CD-M3/H Transient Voltage Suppressor also provides reverse-voltage protection against power surges. When a reverse-voltage is applied to the device, the p-n junction will block the current and effectively clamp the voltage to a preset level. This prevents the reverse voltage from damaging any connected components.

To minimize the risk of overvoltage and ESD damage, the SMBJ16CD-M3/H Transient Voltage Suppressor can be used in a wide variety of applications. For example, they can be used in telecommunication systems, consumer electronics, automotive electronics, office equipment, medical equipment, industrial equipment, etc.

The SMBJ16CD-M3/H Transient Voltage Suppressor is a reliable and low-cost solution for protecting sensitive electronic devices from overvoltage and electrostatic discharge. With its fast response time and low profile, the device is ideal for applications where space is at a premium, reliability is key, and temperature variations are expected.
