Introduction

The TVS0701 device can divert fault currents up to 30 A according to IEC 61000 - 4 - 5 to protect the system from high - power transient impacts or lightning strikes. This device can withstand an open - circuit voltage of 1 kV according to IEC 61000 - 4 - 5 when coupled through a 42 - Ω impedance, meeting the common EMC requirements of industrial signal lines. The TVS0701 uses a feedback mechanism to ensure precise and flat clamping ability during faults, keeping the system contact voltage always lower than that of traditional TVS diodes. Precise voltage regulation allows designers to confidently select system components with lower voltage tolerances, thereby reducing system cost and complexity without sacrificing reliability. The TVS0701 has an operating range of ±7 V and can operate in systems that require protection against reverse wiring situations. Additionally, the TVS0701 adopts a small SON package, suitable for space - constrained applications, with a significantly reduced size compared to standard SMA and SMB packages. Low device leakage current and capacitance ensure minimal impact on the protected lines. To ensure reliable protection throughout the product's lifespan, the TVS0701 was tested with 5000 repeated surge impacts at an ambient temperature of 125 °C, and there was no change in device performance.

The TVS0701 is a bidirectional precision clamp with two integrated FETs driven by a feedback loop to tightly regulate the input voltage during an overvoltage event. This feedback loop leads to a very low dynamic resistance, giving a flat clamping voltage during transient overvoltage events like a surge.

The TVS0701 is a precision clamp that handles 30 A of IEC 61000 - 4 - 5 8/20 - μs surge pulse. The flat clamping feature helps keep the clamping voltage very low to keep the downstream circuits from being stressed. The flat clamping feature can also help end - equipment designers save cost by opening up the possibility to use lower - cost, lower voltage tolerant downstream ICs. This device provides a bidirectional operating range, with a symmetrical VRWM of ±7 V designed for applications that have bipolar input signals or that must withstand reverse wiring conditions. The TVS0701 has minimal leakage at VRWM designed for applications where low leakage and power dissipation is a necessity. Built - in IEC 61000 - 4 - 2 and IEC 61000 - 4 - 4 ratings make it a robust protection solution for ESD and EFT events, and the TVS0701 wide ambient temperature range of - 40 °C to + 125 °C enables usage in harsh industrial environments.

The TVS0701 is specified according to both the IEC 61000 - 4 - 5 and IEC 61643 - 321 standards. This enables usage in systems regardless of which standard is required by relevant product standards or best matches measured fault conditions. The IEC 61000 - 4 - 5 standard requires protection against a pulse with a rise time of 8 μs and a half - length of 20 μs, while the IEC 61643 - 321 standard requires protection against a much longer pulse with a rise time of 10 μs and a half - length of 1000 μs.
