TVS Diode Arrays

Electronic Protection Array for ESD and Overvoltage Protection

The SP721 is an array of SCR/Diode bipolar structures for ESD and

over-voltage protection to sensitive input circuits. The SP721 has 2

protection SCR/Diode device structures per input. There are a total of

6 available inputs that can be used to protect up to 6 external signal or

bus lines. Over-voltage protection is from the IN (Pins 1 - 3 and Pins

5 - 7) to V+ or V-.

The SCR structures are designed for fast triggering at a threshold of one

+V BE diode threshold above V+ (Pin 8) or a -V BE diode threshold below

V- (Pin 4). From an IN input, a clamp to V+ is activated if a transient

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:

Pinout

Refer to Figure 1 and Table 1 for further detail. Refer to Application

Notes AN9304 and AN9612 for additional information.
