TVS diodes, also known as Transient Voltage Suppressor (TVS) diodes, are solid-state devices used for over voltage protection in electronics. TVS diodes are designed to protect sensitive electronics from voltage transients caused by electrostatic discharges, surges, ESD, induction and electro-magnetic interference. They are used in a variety of applications, from the keyboard port on a computer to critical industrial applications. One such TVS diode, the SMB10J17A-M3/5B, is designed for high power and automotive applications. In this article we will discuss its application field, structure and working principle.

Application Field

The SMB10J17A-M3/5B TVS diode is designed for high power and automotive applications. It is ideal for a variety of applications such as: automotive charging and power systems, switchmode power supplies, motor control applications and power line protection. The diode is also suitable for protecting telecom and LAN equipment, computers, consumer electronics, test equipment and medical equipment from electrical surges.

Structure

The SMB10J17A-M3/5B is a silicon-based reverse polarity TVS diode. It is designed with a small body size and low capacitance. The diode has a Voltage Standoff Ratio (VSR) of more than 1.5kW and a peak pulse power rating of 10A. The device is packaged in a SMB (Surface Mount Beach) type package and measures 8.7mm by 4.3mm. The SMB10J17A-M3/5B is a RoHS compliant device.

Working Principle

The SMB10J17A-M3/5B TVS diode works by diverting high-voltage pulses away from sensitive electronics. When a voltage surge or transient is detected, the diode quickly conducts the surge current away from the circuit and into a safe ground. This prevents damage and malfunctioning of sensitive electronics. The diode also helps reduce noise on sensitive circuits by preventing the electromagnetic interference from passing through.

The SMB10J17A-M3/5B is designed to offer high surge capability and fast response times. It has a peak power rating of 10A, an operating voltage of ±18 volts and a peak surge current rating of 15A. The device has a low clamping voltage of 21.3 volts and a response time of less than 1 nanosecond. The diode also features an over-voltage protection circuit, which helps to prevent excessive current surge damage.

In addition to offering protection from electrical surges, the SMB10J17A-M3/5B is also designed to provide a high degree of ESD protection. The device is designed with a high junction capacitance, which helps to reduce device failure due to frequent ESD events. The device also has a low input capacitance, which helps reduce the turn-on time of the device and minimizes current feed-through to the ESD protected circuit.

The SMB10J17A-M3/5B is an ideal choice for high power and automotive applications. It offers protection from voltage transients caused by electrostatic discharges, surges, ESD, induction and electro-magnetic interference. In addition, the device is designed with a small body size, low capacitance, high surge capability, fast response time and high ESD protection.
