NOTES:
(a) For a bridge mounted on1.6mm FR4 PCB with minimum copper pads and track dimensions in still air.
(b) Supply 12V RMS with capacitive bridge load.
(c) Maximum bridge operating junction temperature must be reduced with increased reverse bias voltage to maintain
unconditional thermal stability.
(d) Refer to Design Note DN86
