SP724AHTG

Littelfuse · ESD And Surge Protection (TVS/ESD) · SOT-23-6

SP724AHTG from Littelfuse, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 I/O bidirectional Signal line clamp input to the SCR/diode protection array, clamping transients of either polarity to the V+ and V- rails; the datasheet rates forward peak current at ±2.2A for a 100µs single pulse and ±3A for IEC 61000-4-5 (8/20µs).
2 V- power_in Negative supply rail of the protection array; the operating voltage range is 1V to 20V between V+ and V-, and a bypass capacitor of 0.01µF or larger should be connected closely between V+ and V-.
3 I/O bidirectional Signal line clamp input to the SCR/diode protection array, clamping transients of either polarity to the V+ and V- rails; the datasheet rates forward peak current at ±2.2A for a 100µs single pulse and ±3A for IEC 61000-4-5 (8/20µs).
4 I/O bidirectional Signal line clamp input to the SCR/diode protection array, clamping transients of either polarity to the V+ and V- rails; the datasheet rates forward peak current at ±2.2A for a 100µs single pulse and ±3A for IEC 61000-4-5 (8/20µs).
5 V+ power_in Positive supply rail of the protection array; the continuous supply voltage (V+ minus V-) is absolutely limited to +20V, and a bypass capacitor of 0.01µF or larger should be connected closely between V+ and V-.
6 I/O bidirectional Signal line clamp input to the SCR/diode protection array, clamping transients of either polarity to the V+ and V- rails; the datasheet rates forward peak current at ±2.2A for a 100µs single pulse and ±3A for IEC 61000-4-5 (8/20µs).
