Microsemi .C OM The power dissipation must be held at a level to maintain the junction below the maximum specified operating temperature. Duty cycle control may be used to establish the safe operating condition using a train of pulses. LED Junction temperature may be calculated by use of the following: TJ T Case V F . I Dpk. t p . Rθ JS τ 1 tp τ . Zθ τ tp Zθτ Zθtp TCase is at a specified temperature. VF and IDpk values are read off graph of forward voltage vs drive current. tp and τ are set by the on-time and pulse period of the drive circuit. Thermal Impedances (Zθ) and Thermal resistance (Rθ) values are read from Thermal Impedance graph.
