TVS diodes, also known as Transient Voltage Suppressors (TVS) diodes, are a type of solid state protection component. TVS diodes are designed to protect sensitive electronic components from power surges, transient voltage, electrostatic discharge, and other voltage transients. The SMB10J18AHR5G is a TVS diode that is designed to suppress voltage transients up to 24 V when in unidirectional mode and up to 18 V when in bidirectional mode. It is suitable for a wide range of applications, such as automotive, audio/visual systems, and computers.

The SMB10J18AHR5G is a three-terminal TVS diode that utilizes a pair of unidirectional diodes and a central single bidirectional diode. The unidirectional diodes offer protection against overvoltage transients and the bidirectional diode offers protection against both positive and negative overvoltage transients. The diodes are arranged in a parallel configuration, allowing for a faster response time when faced with a voltage transient.

The SMB10J18AHR5G has an operating range of -55°C to +175°C and is designed to withstand peak pulses up to 50A when applied with a 10/1000μs surge current waveform. This device is also designed to withstand a repetitive peak pulse power of 350 W using an 8/20 μs pulse waveform. The diode is capable of achieving a peak clamping voltage of 43 V when using a unidirectional current and 28 V when using a bidirectional current.

The SMB10J18AHR5G is a versatile diode that is suitable for many applications including automotive, audio/visual systems, and computers. It can be used to protect circuit components from overvoltage transients such as those caused by lightning strikes, power surges, or electrostatic discharges. It also can be used to provide power line protection from transients generated by motor controllers and inductive loads.

The SMB10J18AHR5G is a robust and reliable device with a low capacitance and its fast response time make it ideal for use in a wide range of applications. With its wide operating temperature range, it is suitable for use in high temperature environments where other TVS diodes may not be suitable. Additionally, this device offers excellent reverse leakage properties, making it suitable for use in circuits that require protection from both positive and negative voltage transients.
