2 / 11 page www.vishay.com 2 Document Number: 71863 S11-1185-Rev. F, 13-Jun-11 Vishay Siliconix Si4724 This document is subject to change without notice. THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 Notes: a. Surface mounted on 1" x 1" FR4 board, full copper two sides. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Notes: a. Surface mounted on 1" x 1" FR4 board. b. Junction-to-foot thermal impedance represents the effective thermal impedance of all heat carrying leads in parallel and is intended for use in conjunction with the thermal impedance of the PC board pads to ambient (RthJA = RthJF + RthPCB-A). It can also be used to estimate chip tem- perature if power dissipation and the lead temperature of a heat carrying (drain) lead is known.
