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

Littelfuse SP724AHTG TVS Diode Array offers 20V, 6-pin SOT-23 protection against electrostatic discharge (ESD) and transient voltage events for sensitive electronic circuits. It features a quad array of transient voltage clamping circuits designed 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, the device offers reliable performance and good solderability. Its bipolar SCR/diode structures can protect up to four independent lines by clamping transient spikes of either polarity directly to the power supply rails, helping to safeguard sensitive digital or analogue input circuits.

A key advantage is its very low leakage current (typically 1 nA) and extremely low input capacitance (typically 3 pF). This minimal loading makes it suitable for high-speed data lines where signal integrity is paramount. It is rated to meet the IEC 61000-4-2 ESD immunity standard at Level 4 for both contact and air discharge methods.
