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
+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 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.
Refer to Fig 1 and Table 1 for further details. Refer to Application Note
AN9304 and AN9612 for further detail.

ESD Capability
ESD capability is dependent on the application and defined test
standard.The evaluation results for various test standards and methods
based on Figure 1 are shown in Table 1.
The SP723 has a Level 4 HBM capability when tested as a device to the
IEC 61000-4-2 standard. Level 4 specifies a required capability greater
than 8kV for direct discharge and greater than 15kV for air discharge.
For the “Modified” MIL-STD-3015.7 condition that is defined as an “in-
circuit” method of ESD testing, the V+ and V- pins have a return path to
ground and the SP723 ESD capability is typically greater than 25kV from
100pF through 1.5kΩ. By strict definition of MIL-STD-3015.7 using “pin-
to-pin” device testing, the ESD voltage capability is greater than 10kV.
For the SP723 EIAJ IC121 Machine Model (MM) standard, the ESD capa-
bility is typically greater than 2kV from 200pF with no series resistance.
