These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTE 1: Voltage values are with respect to the ANODE terminal, unless otherwise noted. NOTE 2: ESD Protection Level per AEC Q100 Classification package thermal data (see Note3) PACKAGE BOARD θJC θJA SOT-23-5 (DBV) High K, JESD 51-7 131°C/W 206°C/W SOT-23-3 (DBZ) High K, JESD 51-7 76°C/W 206°C/W NOTE 3: Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) − TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability. recommended operating conditions MIN MAX UNIT VKA Cathode voltage Vref 36 V IKA Cathode current 1 100 mA TA Operating free-air temperature range −40 125 °C |
