On 7 February 2017 the former NXP Standard Product business became a new company with the
tradename Nexperia. Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS
semiconductors with its focus on the automotive, industrial, computing, consumer and wearable
application markets
In data sheets and application notes which still contain NXP or Philips Semiconductors references, use
the references to Nexperia, as shown below.

8.Application information
The MMBZxAL series is designed for the protection of up to two unidirectional data or
signal lines from the damage caused by ESD and su rge pulses. The devices may be u sed
on lines where the signal polarities are either positive or negative with respect to ground.
The MMBZ5V6AL, MMBZ6V2AL, MMBZ6V8AL, MMBZ9V1AL and MMBZ10VAL provide
a surge capability of 24 W per line, the MMBZ12VAL, MMBZ15VAL, MMBZ18VAL,
MMBZ20V AL, MMBZ27VAL and MMBZ33VAL provide a surge capability of 40 W per line,
for a 10/1000 μs waveform.

Circuit board layout and protection device placeme nt
Circuit board layout is critical for the suppression of ESD, Electrical Fast Transient (EFT)
and surge transients. The following guidelines are recommende d:
1. Place the MMBZxAL series as close to the input terminal or connector as possible.
2. The path length between the MMBZxAL series and the protected line should be
minimized.
3. Keep parallel signal paths to a minimum.
4. Avoid running protected conductors in parallel with unprotected conductors.
5. Minimize all PCB conductive loops including power and ground loops.
6. Minimize the length of the transient return path to ground.
7. Avoid using shared transient return paths to a common ground point.
8. Ground planes should be used whenever possible. For multilayer PCBs, use ground
vias.
