Valid provided that leads are kept at ambient temperature at a distance of 8 mm from case. 3) The ZPD1 is a silicon diode operated in forward direction. Hence, the subscript of all parameter should be "F" instead of "Z". Connect the cathode terminal to the negative pole. 2) SEMTECH ELECTRONICS LTD. ® (Subsidiary of Sino-Tech International Holdings Limited, a company listed on the Hong Kong Stock Exchange, Stock Code: 724) Dated : 23/06/2007 ZPD1...ZPD75 SEMTECH ELECTRONICS LTD. ® (Subsidiary of Sino-Tech International Holdings Limited, a company listed on the Hong Kong Stock Exchange, Stock Code: 724) Dated : 23/06/2007
