App note: Precautions when measuring the rear of the package with a thermocouple on power devices

App note from ROHM Semiconductors when measuring thermals along exposed pads on power devices. Link here (PDF) When measuring the rear of the package with a thermocouple, to measure accurately, the thermocouple must be in close contact with the package. A thermal pad for heat dissipation is exposed on the rear side and this thermal […]

App note: Torque recommendations for TO-220 devices

App note from Vishay on the impact of torque on thermal resistance of TO-220 devices. Link here (PDF) When the TO-220 was first introduced, most applications required something less than the full power handling capabilities of this package. Hence, the TO-220 is almost taken for granted in terms of its excellent power handling capacity and […]

App note: Package-related thermal resistance of LEDs

App note from OSRAM on thermal resistance for LEDs and IREDs (IR emitting diodes). Link here (PDF) In order to achieve the expected reliability, lifetime and optimal performance of LEDs, especially for high-power LEDs, appropriate thermal management is of the utmost importance. One of the key parameters for good thermal management is the temperature of […]

App note: Optimizing PCB Thermal Performance for LEDs

Application note from CREE on efficiently designing a conventional FR4 PCB to manage thermal heat and as a cheap alternative to metal core pcbs. Link here (PDF) One of the most critical design parameters for an LED illumination system is the system’s ability to draw heat away from the LED junction. High operating temperatures at […]

App note: Thermal management basics and its importance for LED luminaire performance and cost

Article about thermal management on LED luminaire from TT Electronics. Link here (PDF) LED luminaires are being marketed today as an alternative lighting technology that reduces power consumption and maintenance costs for commercial and residential installations. Thermal management has a significant impact upon the lifetime, performance and cost of an LED luminaire. Without proper application […]

App note: Thermal management in surface-mounted resistor applications

App note from Vishay on PCB thermal management specifically on components like SMD resistors, where if allowed a design change (e.g. change in SMD size or change in more heat tolarant ones) must be implemented in order to squeeze more thermal capability. Link here (PDF) Thermal management is becoming more important as the density of […]
