TVS (Transient Voltage Suppressor) diodes are especially designed for easy protection of electronic devices against voltage spikes or electro-static discharge (ESD). The SMBJ36C is a bidirectional transient voltage suppressor diode designed to protect sensitive electronic components from voltage transients caused by lightning and other transient voltage events. It is designed to handle up to 36V peak working voltage, and can dissipate up to 1500 W peak pulse power.

The SMBJ36C is compatible with lead-free processing. It is suitable for mounting on the board with any surface mount process and has been engineered to maximize surge current capability while minimizing board space. It is also ESD protected with a clamping voltage that is typically about 20V lower than its peak pulse power rating.

The SMBJ36C is commonly used for AC/DC power supply and consumer electronic system applications, such as personal computers, networking, external storage devices, and modules. The SMBJ36C is also suitable for over-voltage and over-current protection and in-circuit protection applications. In addition, it can be used in any application where lightning or electrostatic discharge protection is required.

The working principle of the SMBJ36C diode is based on the failure of the p-n junction when the voltage applied across it is greater than its breakdown voltage. When the fast rising transient voltage exceeds the peak inverse voltage of the diode, it starts to conduct, clamping the voltage and diverting current away from the device. This reduces the peak instantaneous voltage and clamps its peak pulse power.

The SMBJ36C is designed and tested to meet MIL-STD-750A requirements, and its operating temperature is -55 °C to 125 °C. It is also flammability rated for UL 94V-0 to ensure its safe application against explosions and other hazards. The SMBJ36C’s high reliability and performance make it the perfect choice for overall overvoltage transient protection in AC/DC power supplies and consumer electronic systems.
