TVS Diode Arrays
Electronic Protection Array for ESD and Overvoltage Protection
SP720
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-.
The SCR structures are designed for fast triggering at a threshold of one
+V BE diode threshold above V+ (Pin 16) or a -V BE diode threshold
below V- (Pin 8). From an IN input, a clamp to V+ is activated if a tran-
sient pulse causes the input to be increased to a voltage level greater
than one V BE above V+. A similar clamp to V- is activated if a negative
pulse, one V BE less than V-, is applied to an IN input. Standard ESD
Human Body Model (HBM) Capability is:
Refer to Figure 1 and Table 1 for further detail. Refer to Application Note
AN9304 and AN9612 for additional information.
