Device placement and printed-circuit board layout

Circuit board layout is of extreme importance in the

suppression of transients. The clamping voltage of the

BZA462A is determined by the peak transient current and

the rate of rise of that current (di/dt). Since parasitic

inductances can further add to the clamping voltage

(V = L di/dt) the series conductor lengths on the

printed-circuit board should be kept to a minimum. This

includes the lead length of the suppression element.

In addition to minimizing conductor length the following

printed-circuit board layout guidelines are recommended:

1. Place the suppression element close to the input

terminals or connectors.

2. Keep parallel signal paths to a minimum.

3. Avoid running protection conductors in parallel with

unprotected conductors.

4. Minimize all printed-circuit board loop areas including

power and ground loops.

5. Minimize the length of the transient return path to

ground.

6. Avoid using shared transient return paths to a common

ground point.
