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.
