Littelfuse SP724AHTG TVS Diode Array, SOT-23, 20V, 6-Pin

The Littelfuse SP724AHTG is a high-performance TVS Diode Array designed to provide robust electrostatic discharge (ESD) and transient voltage protection for sensitive electronic circuits. It features a quad array of transient voltage clamping circuits engineered to suppress harmful overvoltage events on data, signal, or control lines operating on power supplies up to 20 VDC.

Constructed with a moulded epoxy body and matte tin-plated copper alloy leads, this device offers reliable performance and good solderability. Its sophisticated bipolar SCR/diode structures can protect up to four independent lines by clamping transient spikes of either polarity directly to the power supply rails, ensuring sensitive digital or analogue input circuits are safeguarded.

A key advantage of the SP724AHTG is its combination of very low leakage current (typically 1 nA) and extremely low input capacitance (typically 3 pF). This minimal loading makes it ideal for high-speed data lines where signal integrity is paramount. Furthermore, it is certified to meet the rigorous IEC 61000-4-2 ESD immunity standard, achieving Level 4 protection for both contact and air discharge methods.
