TEC1-12706 Thermoelectric Cooler Peltier Module – 12V DC

The TEC1-12706 Thermoelectric Cooler Peltier Module is a 40mm × 40mm × 3.6mm bismuth telluride thermoelectric tile rated at 12V DC with 6A maximum current, 92W heat pumping capacity (Qmax), 15.4V maximum voltage, and 1.98Ω ±10% internal resistance. The peltier module 12v works on the Peltier effect — when DC current passes through the module’s semiconductor junctions, one face becomes cold while the opposite face becomes hot, creating a temperature differential across the two ceramic surfaces without any moving parts, refrigerant, or compressor.

The peltier module tec1 12706 model designation indicates key specifications: “12” for 12V rated voltage and “06” for 6A maximum current. At full 12V/6A operation, this tec1 12706 thermoelectric cooler peltier draws 72W of electrical power to pump up to 92W of heat from cold side to hot side — the difference (92W − 72W) represents the thermodynamic efficiency of heat pumping versus electrical input. Critically, the thermoelectric cooler peltier hot side must be aggressively cooled with a heatsink and fan during operation — without hot-side cooling, thermal runaway occurs rapidly as the hot side heats both the junction and the cold side simultaneously, eliminating the temperature differential entirely.

the thermoelectric peltier module’s efficiency is significantly lower than vapour-compression refrigeration (typical COP of 0.3-0.5 vs refrigerator’s 2-4), meaning it consumes considerably more electricity per watt of cooling than a traditional refrigerator — making it most practical for small, precise, or solid-state cooling applications where compactness matters over efficiency. Well-suited for learners and makers, TEC1-12706 module available at StemVolt, enables creative electronics, temperature regulation, and compact cooling projects using thermoelectric.
