TVS Diode Arrays
Electronic Protection Array for ESD and Overvoltage Protection
SP723
The SP723 is an array of SCR/Diode bipolar structures for ESD and
over-voltage protection of sensitive input circuits.The SP723 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
+VBEdiode threshold above V+ (Pin 8) or a -VBEdiode 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 VBEabove V+. A similar clamp to V- is activated if a negative pulse,
one VBEless 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.
