TVS - Diodes (Transient Voltage Suppression Diodes) are semiconductor devices that protect electrical circuits during voltage spikes. They are commonly used in devices that are subject to lightning strikes, electrostatic discharge, or high-speed switch circuits. The SMB10J30A R5G is a type of TVS diode that is used to protect circuits in the automotive, industrial, and medical fields.The SMB10J30A R5G is a low-capacitance bidirectional low-power TVS diode manufactured by ROHM Semiconductor. It is designed to protect circuits from electrostatic discharge, electrical fast transients, and lightning strikes. This diode features a fast response time, low leakage current, and an operating voltage range of 15 watts. The SMB10J30A R5G is RoHS-compliant and is UL/IEC approved.The SMB10J30A R5G is a low-capacitance diode that can be used in applications where the cancellation of a high-capacitance response is required. It operates with a stand-off voltage of 28V, a clamping voltage of 41V, and an operating current of 15A. It is capable of withstanding transient voltage up to 30W. The diode is able to switch from OFF to ON state in under 1.3 nanoseconds, allowing it to protect the circuit during voltage spikes.In terms of application, the SMB10J30A R5G can be used in automotive, industrial, and medical applications. This diode is a popular choice for automotive EMI/RFI suppression and protection due to its low insulation resistance and low clamping voltage. In industrial applications, the diode can be used to protect against power surges in high-speed switch circuits. In medical applications, the diode can be used to protect portable medical devices, such as infusion pumps, from electrical spikes.The SMB10J30A R5G utilizes a Zener diode structure, which works by conducting current when the forward voltage exceeds the device\'s threshold. When a voltage spike occurs, the Zener diode switches from OFF to ON state, quickly shunting excess voltage away from the circuit. While in the ON state, the device begins to dissipate heat as the current is conducted through the diode. The diode then switches back OFF when the voltage drops below the threshold voltage.The SMB10J30A R5G is a reliable and efficient TVS diode that offers protection from electrostatic discharge, electrical fast transients, and lightning strikes. It is used in a variety of applications and provides fast response time, low leakage current, and a robust EMI/RFI suppression. The diode is RoHS-compliant and is UL/IEC approved, making it a popular choice for automotive, industrial, and medical applications.
