General Purpose ESD Protection - SP721 Series
SP721 Series 3pF 4kV Diode Array

Pb GREEN
Description
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
Pinout
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.
