Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook Handling PrecautionDerating Concept and Method) and individual reliability data (i.e. reliability test report and estimated failure rate, etc). Note 1: Ensure that the channel temperature does not exceed 150 . Note 2: Pulse width (PW) 10 ms, duty 1% Note 3: Device mounted on an FR4 board. (25.4 mm 25.4 mm 1.6 mm ,Cu pad: 645 mm2) Note: The MOSFETs in this device are sensitive to electrostatic discharge. When handling this device, the worktables, operators, soldering irons and other objects should be protected against anti-static discharge. Note: The channel-to-ambient thermal resistance, R , and the drain power dissipation, P , vary according to th(ch-a) D the board material, board area, board thickness and pad area. When using this device, be sure to take heat dissipation fully into account. 2014-03-12 2 Rev.2.0
