Description

The SP1848-27145 Thermoelectric Power Generator (TEG) module utilizes advanced bismuth telluride semiconductor materials to directly convert thermal energy into electrical energy. Operating on the Seebeck principle, it generates a voltage proportional to the temperature gradient applied across its ceramic plates. The module is hermetically sealed to protect internal thermoelectric elements from environmental moisture and degradation, ensuring long-term reliability in energy harvesting setups.

Designed for power generation rather than active cooling, this TEG module features a robust construction capable of withstanding sustained high-temperature differentials. Its performance is characterized by a predictable voltage and current output curve relative to the applied temperature difference, making it suitable for integration into systems monitoring heat flux or scavenging waste heat from engines, industrial processes, or even body heat.

Key Features

  • Thermoelectric Power Generation: Converts heat differentials directly into DC electricity using the Seebeck effect.
  • High-Temperature Rated: Withstands continuous operation up to 120°C on the hot side.
  • Moisture-Sealed Design: Encapsulated construction protects internal semiconductor elements from humidity and corrosion.
  • Optimized for Energy Harvesting: Thermal elements are formulated specifically for maximum Seebeck coefficient and power output.
  • Pre-attached Wiring: Includes 200mm long lead wires for immediate connection to power management circuits.
  • Compact & Lightweight: Measures 40x40mm and weighs only 30g for easy integration into space-constrained applications.
  • Extended Service Life: Rated for over 200,000 hours of operational life under specified conditions.

Applications

  • Waste heat recovery from automotive exhaust systems or industrial machinery.
  • Energy harvesting for wireless sensor nodes in IoT and remote monitoring systems.
  • Powering low-consumption electronics (e.g., sensors, microcontrollers) using body heat or ambient thermal gradients.
  • Thermoelectric generator prototypes and educational demonstrations of the Seebeck effect.
  • Backup or supplementary power sources for off-grid and portable equipment.

Frequently Asked Questions

What is the correct way to orient and mount the SP1848-27145 TEG module?

The side marked with the model number (SP1848-27145) must face the heat sink or cold source. The opposite, unmarked side must face the heat source. Applying thermal grease (2-3 drops) on both ceramic surfaces is critical to minimize thermal resistance and maximize power generation efficiency. Incorrect orientation will severely reduce output.

What voltage and current can I expect from this thermoelectric generator?

Output is directly proportional to the temperature difference (ΔT). At a ΔT of 100°C (e.g., 120°C hot side, 20°C cold side), it can produce approximately 4.8V open-circuit voltage and 669mA short-circuit current. At lower ΔT, outputs are lower (e.g., ~0.97V at ΔT=20°C). For stable voltage, a DC-DC booster or power management circuit is recommended.

Can this module be used for active cooling like a standard Peltier module?

No. The SP1848-27145 is optimized and formulated specifically for power generation (Seebeck mode). Its internal semiconductor doping and element geometry are designed to maximize voltage output from a temperature gradient, not to pump heat. Using it as a cooler will be inefficient and may damage the module.

What is the maximum temperature I can apply to the hot side?

The absolute maximum operating temperature for the hot side is 120°C. Exceeding this limit can cause permanent damage to the semiconductor junctions, degrade the solder joints, and lead to premature failure. Always ensure the cold side is adequately heatsunk to maintain a sufficient ΔT without the hot side exceeding its rating.
