SP720AB

瞬态抑制二极管阵列 - 插卡电脑保护阵列的ESD和过电压保护 TVS Diode Arrays - Elctronic Protection Array for ESD and Overvoltage Protection

The SP720 is an array of SCR/Diode bipolar structures for ESD and over-voltage protection to sensitive input circuits. The SP720 has 2 protection SCR/Diode device structures per input. A total of 14 available inputs can be used to protect up to 14 external signal or bus lines. Over-voltage protection is from the IN pins 1-7 and 9-15 to V+ or V-.
