ZR431L Absolute Maximum Ratings
(@TA = +25°C, unless otherwise specified.) (Note 4)
Symbol Parameter Rating Unit
VZ Cathode Voltage 10 V IZ Cathode Current 50 mA TJ Junction Temperature -40 to +125 °C TSTG Storage Temperature -55 to +105 °C θJA Thermal Resistance SOT23 380 °C/W Note 4: 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 conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
