cms04 2013-11-01 2 marking abbreviation code part no. s4 cms04 standard soldering pad handling precaution schottky barrier diodes have reverse current ch aracteristic compared to the other diodes. there is a possibility sbd may cause th ermal runaway when it is used under high temperature or high voltage. this device is v f -i rrm trade-off type, lower v f higher i rrm ; therefore, thermal r unaway might occur when voltage is applied. please take forward and reverse loss into consideration during design. the absolute maximum ratings denote the absolute maximu m ratings, which are rated values and must not be exceeded during operation, even for an instant. the following are the genera l derating methods that we recommend when you design a circuit with a device. v rrm : use this rating with reference to the above. v rrm has a temperature coefficient of 0.1%/c. take this temperature coefficient into account designing a device at low temperature. i f(av) : we recommend that the worst case current be no greater than 80% of the absolute maximum rating of i f(av) and t j be below 100c. when using this device, take the margin into consideration by using an allowable tamax-i f(av) curve. i fsm : this rating specifies the non-repetitive peak curren t. this is only applied for an abnormal operation, which seldom occurs during the lifespan of the device. t j : derate this rating when using a device in order to ensure high reliability. we recommend that the device be used at a t j of below 100c. thermal resistance between junction and ambient fluctuat es depending on the device?s mounting condition. when using a device, please design a circuit board and a solderin g land size to match the appropriate thermal resistance value. please refer to the rectifiers databook for further information. 3.0 1.4 2.1 unit: mm 1.4
