SP721 Series 3pF 4kV Diode Array

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_BEdiode threshold above V+ (Pin 8) or

a -V_BEdiode 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_BEabove V+. A similar clamp to V- is activated if a negative

Pinout

pulse, one V_BEless than V-, is applied to an IN input.

Standard ESD Human Body Model (HBM) Capability is:
