Technical Specifications
    Tolerance: ±1% Power Rating Without Heatsink (25°C): 2,25W With Heatsink1) (25°C): 30W Operating Voltage, Max.: 250V Dielectric Strength: 1500Vrms Temperature Coefficient ³0,1W: ±250ppm/°C ³0,5W: ±150ppm/°C Thermal Resistance: 4,2°C/W Temperature Range: -55...+155°C Climatic Category: 55/155/56 Derating: See Curve
1) For calculation of heatsink please see values below Note.
• You will find suitable heatsinks at product group G9511.
Calculation of heatsink
P = DT / [RTH(j-c) + RTH(c-a)]

P = Expressed in W
DT = Difference between maximum working temperature (155°C) and room temperature
RTH(j-c) = Thermal resistance of the component
RTH(c-a) = Thermal resistance of the heatsink and quality of fastening device

Ambient temperature 30°C, Power Rating: 10W
1) P = DT / [RTH(j-c) + RTH (c-a)]
2) DT = 155°C - 30°C = 125K
3) [RTH(j-c) + RTH (c-a)] = DT / P = 125K / 10W = 12,5K/W4) RTH (c-a) = 12,5K/W - 4,2K/W = 8,3K/W
