SP724AHTG Description

Short technical summary and product information.

The SP724AHTG is a quad array of transient voltage clamping circuits designed to suppress ESD and other transient over-voltage events. It protects up to four independent lines using SCR/diode structures that clamp transients to the power supply rails.

 

Key electrical specifications include a maximum single-ended supply voltage of 20V and differential supply voltage of ±10V. ESD capability meets IEC 61000-4-2 Level 4 with 8kV contact discharge and 15kV air discharge. Peak pulse current is ±3A (8/20µs) and ±2.2A (single pulse, 100µs). The device features low input leakage of 1nA typical and low input capacitance of 3pF typical, minimizing signal degradation on protected lines.

 

The SP724AHTG operates over a temperature range of -40°C to 105°C. It is housed in a 6-lead SOT-23 surface mount package (SOT-23-6), suitable for compact PCB designs. Applications include microprocessor and logic input protection, data bus protection, analog device input protection, and general transient voltage clamping.
