SP724AHTG TVS Diode Arrays (SPA® Diodes)
General Purpose ESD Protection - SP724 Series
ESD 抑制器/TVS 二极管 20V 2.2A 4 CHANNEL
Description SP724AHTG
The SP724 is a quad array of transient voltage clamping circuits designed to suppress ESD and other transient overvoltage events. The SP724 is used to help protect sensitive digital or analog input circuits on data, signal, or control lines operating on power supplies up to 20VDC. The SP724 is comprised of bipolar SCR/diode structures to protect up to four independent lines by clamping transients of either polarity to the power supply rails. The SP724 offers very low leakage (1nA Typical) and low input capacitance (3pF Typical). Additionally, the SP724 is rated to withstand the IEC 61000-4-2 ESD specification for both contact and air discharge methods to level 4. The SP724 is connected to the sensitive input line and its associated power supply lines. Clamping action occurs during the transient pulse, turning on the diode and fast triggering SCR structures when the voltage on the input line exceeds one VBE threshold above the V+ supply (or one VBE threshold below the V- supply). Therefore, the SP724P operation is unaffected by poor power supply regulation or voltage fluctuations within its operating range.
