PyroFuse from Sensata Technologies – the ultimate high-voltage safety solution.
The STPS500 series PyroFuse is specially designed to support a wide range of high-voltage applications, including automotive, charging, aviation, and industrial systems. In the event of a short circuit or accident, the device quickly disconnects the load, protecting both the electrical system and the safety of the driver and passengers.

It offers key features such as high continuous current carrying capacity, fast response time, high breaking capacity, excellent re-insulation resistance, and a fully enclosed housing that prevents gas emissions during interruption events. These features work together to improve overall system safety and reliability, all in a lightweight, compact design that integrates seamlessly without adding significant weight or bulk.

Highlights
• Max continuous current 500A.
• Max breaking capacity:
1) 500V/20000A @14uH.
2) 1000V/16000A @16uH.
• Bidirectional device
• Irreversible current separation (one-time)

Advantages
Active safety with external control
Fast circuit interruption <1ms
>50MΩ @ 1000V
Lightweight design and small form factor

Applications
Battery disconnection to prevent fire or damage due to short circuit or electric shock during/after an accident.
For high-voltage applications in electric vehicles, aviation (including eVTOL), and industry.
