A Transient Voltage Suppression (TVS) diode is a semiconductor device that is designed to protect safety-critical electrical circuits from the effects of overvoltage transients. A TVS diode is an example of a surge-protection device (SPD) designed to protect systems against improperly connected mains and other transient sources such as lightning. The number of transients, which can cause significant disruption or even harm devices, can be much greater in industrial environments, so a reliable and robust surge protection is essential. The TPSMB36CA is a TVS diode that has been specifically designed for industrial applications.

The TPSMB36CA is a bi-directional, low capacitance, transient voltage suppression (TVS) diode array designed to protect against over-voltage transients. The device contains two 1200 W, 5.0 V, bidirectional components providing superior over-voltage protection for data line and It can also be used in various application fields such as medical instrumentation, computer peripherals, and consumer products that need surge protection. It is qualified to AEC-Q101 automotive standards, making it an ideal choice for automotive applications.

The TPSMB36CA is a low-profile device, allowing it to be used in a wide variety of applications. The device has an RoHS-compliant package and is rated for operating temperatures of -55 to +175°C and offers excellent surge and ESD protection. The maximum surge current is 4A (8/20µs) and the clamping voltage is 5.2V. It also has a low reverse leakage current of 2 μA @ 5V.

In terms of its working principle, the TPSMB36CA monitors the circuit for any voltage changes. When it detects a voltage spike, it actively reduces the voltage across its terminals to a safe level. It does this by clamping the voltage using its two bi-directional components. The device can respond to transients in both positive and negative direction. This means it can offer protection in both directions and is suitable for applications where reverse polarity can occur. When in operation, the device maintains a low on-state resistance and low capacitance.

The TPSMB36CA is an ideal surge protection device for industrial applications due to its low profile, high surge current protection (4A) and low clamping voltage. It is also designed for a wide range of operating temperatures and is rated for AEC-Q101 automotive standards, making it a great choice for automotive applications with its superior surge and ESD protection. Finally, its bi-directional nature ensures optimal protection against both over-voltage and reverse polarity events. Therefore, the TPSMB36CA is an ideal choice for industrial and automotive applications in need of surge protection.
