TVS Diode Arrays
Electronic Protection Array for ESD and Overvoltage Protection
SP721
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
+VBE diode threshold above V+ (Pin 8) or a -VBE 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 VBE above V+. A similar clamp to V- is activated if a negative pulse,
one VBE less than V-, is applied to an IN input. Standard ESD Human
Body Model (HBM) Capability is:
