Applications

The SP725 is an array of SCR/Diode bipolar structures for

ESD and overvoltage protection of sensitive input circuits.

The SP725 has 2 protection SCR/Diode device structures

per input. There are a total of 4 available inputs that can be

used to protect up to 4 external signal or bus lines. Over-

voltage protection is from the IN (Pins 1 - 4) to V+ or V-.

The SCR structures are designed for fast triggering at a

threshold of one +V

diode threshold above V+ (Pin 5,6)

or one –V

diode threshold below V- (Pin 7,8). 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

above V+. A similar clamp to V- is activated if

a negative pulse, one V

less than V-, is applied to an IN

input.

Refer to Fig 1 and Table 1 for further details. Refer to

Application Note AN9304 and AN9612 for further detail.
