MIC5021 TEMPERATURE SPECIFICATIONS (Note 1) Parameters Sym. Min. Typ. Max. Units Conditions Thermal Resistance, PDIP-8Ld JA –40 — 85 °C Maximum Ambient Temperature Thermal Resistance, SOIC-8Ld JA –40 — 85 °C Maximum Ambient Temperature Junction Thermal Resistances Note 1: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature and the thermal resistance from junction to air (i.e., TA, TJ, JA). Exceeding the maximum allowable power dissipation will cause the device operating junction temperature to exceed the maximum rating. Sustained junction temperatures above the maximum rating can impact the device reliability. 2016 Microchip Technology Inc. DS20005677A-page 5
