PRODUCTION DATA
The multiple ground pins provided lower the connection resistance to ground. In order to improve circuit operation, a connection to all ground pins must be provided on the system printed circuit board. Without proper device connection to ground, the speed and protection capability of the device will be degraded.
Direct connective paths of the traces are taken to the suppressor mounting pads to minimize parasitic inductance in the surge-current conductive path, thus minimizing L(di/dt) effects.
