Product Description
Littelfuse SM712-02HTG is a 2-element bi-directional Transient Voltage Suppression (TVS) diode array engineered to protect sensitive electronic circuits from electrostatic discharge (ESD), electrical fast transients (EFT), and lightning-induced surges. This device delivers a peak pulse power dissipation of 600 W with an ability to withstand surge currents up to 19 A (8/20 μs waveform), making it ideal for safeguarding RS-485 communication lines and other asymmetric voltage applications between -7 V and 12 V.
The SM712-02HTG features a compact 3-pin SOT-23 surface-mount package with dimensions of 3.04 mm length, 1.4 mm width, and 1.02 mm height, offering low profile integration in space-constrained designs.
Its dual-element diode configuration provides effective bi-directional protection with a minimum breakdown voltage of 13.3 V and a maximum reverse stand-off voltage of 12 V. The device maintains a low clamping voltage of 31 V under surge conditions, ensuring sensitive components are shielded from harmful voltage spikes.
Operating reliably across a broad temperature range from -40°C to 125°C, the SM712-02HTG is compliant with automotive standard AEC-Q101, underscoring its suitability for automotive and industrial environments requiring high reliability.
Additional features include a maximum reverse leakage current of just 1 μA and a fast response time under 500 ns, ensuring minimal impact on signal integrity and circuit operation.
Reliable electrostatic discharge (ESD) protection for RS-485 and similar communication interfaces. Bi-directional dual-element diode configuration enabling balanced surge suppression. Compact SOT-23 surface-mount package for space-saving PCB layouts.
High peak pulse power of 600 W with 19 A surge current handling capacity. Wide operating temperature range from -40°C to 125°C for diverse applications. Compliance with AEC-Q101 automotive standard, suitable for automotive electronics.
Low reverse leakage current and low clamping voltage for effective voltage spike suppression. Fast response time under 500 ns for prompt protection.
This Littelfuse TVS diode array is widely used in industrial, automotive, communication, and electronic equipment applications to enhance device durability and system reliability by protecting against transient voltage events.
