Product Description
Littelfuse SM712-02HTG is a 2-element bi-directional TVS diode array designed to provide robust electrostatic discharge (ESD) protection for sensitive electronic circuits. Encapsulated in a compact 3-pin SOT-23 surface-mount package, this device supports reliable defense against surges up to 600 W peak pulse power dissipation.
This TVS diode array features dual diodes capable of clamping voltage to 31 V while handling peak pulse currents of 19 A, making it ideal for protecting data lines such as RS-485 communication interfaces that operate with asymmetrical working voltages. Its bi-directional configuration ensures effective suppression of positive and negative voltage transients, enhancing protection across varied applications.
The diode's minimum breakdown voltage is 13.3 V, with a maximum reverse standoff voltage of 12 V, giving it accurate clamping during transient events. It operates efficiently across a temperature range from -40 °C to 125 °C and meets the stringent automotive AEC-Q101 quality standard, ensuring high reliability in automotive and industrial environments.
The low profile design measures only 3.04 mm in length, 1.4 mm in width, and 1.02 mm in height, enabling compact PCB layouts. This diode array offers extremely fast response times of under 500 nanoseconds, suitable for protecting circuits from rapid electrical fast transients (EFT) and lightning-induced surges.
Dual diode bi-directional configuration for balanced overvoltage protection. 600 W peak pulse power dissipation for high-energy transient mitigation. Automotive standard AEC-Q101 certified for demanding applications. Surface mount SOT-23 package for easy PCB integration.
Operating temperature range from -40 °C to 125 °C for versatility. Low leakage current minimizes interference with signal integrity. Compact dimensions enable space-efficient board layouts. Designed for applications requiring robust ESD and surge protection like RS-485 interfaces.
Manufactured in Thailand, the SM712-02HTG TVS diode array is suitable for industrial, automotive, telecommunication, and consumer electronics sectors. It delivers reliable surge suppression to enhance the longevity and safety of electronic assemblies.
