NanoSeconds rise/fall time, High-Voltage push-pull switches
A switch belongs to the family of push-pull switches consists of two alternately controlled
solid-state switches, which in turn are made up to a large number of high-speed MOSFETs
isolated each other connected in series. The rise and fall times at the switch output are
virtually the same and that allow generating an extremely precise, high-voltage, true
square-wave pulses.

Transient Protection: All loads are inductive, even ones that are not so obvious or labeled. An inductive load produces a harmful transient voltage,
which is much higher than the applied voltage, when it is turned on and off. A SSR built with a MOSFET output acts as an ideal switch and can
produce a seemingly “non-inductive” load, which can cause damage if not suppressed. A transient voltage suppressor, which is bi-directional for AC
applied voltage and unidirectional for DC applied voltage, should be used to clamp excessive spikes.

Fig. 5 Switching Time Test Circuit
A switch can be controlled via the enable (EN) input (“L”/”H”), if only + or - power needs to be applied
on a load, or via the control (CS) when a bipolar power must applied onto the load.

NOTES:
1. Wiring should be as short as possible
2. Capacitor Cp should be at least 50 times of Cl for shortest transition times
3. Connected in series resistors R14 and R15 used for dumping and short protection. All
measurements refer to 50 Ohm. According to a specific application, resistors can be
between 0 (zero) and 1Mohm and should be selected the highest possible to avoid ringing.
4. A low impedance linkage between logic GND and earth is very important for interference
free operation with a high switching speed.
