Circuit Protection That Goes Beyond Cooling
TCLAD offers a comprehensive portfolio of overcurrent protection devices, empowering engineers to monitor load currents and respond quickly to potentially damaging electrical events. Trusted across a wide range of industries and applications, our circuit protection solutions enhance system reliability, improve efficiency and support user safety.
Why is Overcurrent Protection Important?
Overcurrent is a critical indicator of rising circuit temperature and potential fault conditions — such as ground faults and short circuits — that can result in fires or system failure. Even without immediate consequences, sustained overcurrent and elevated temperatures can gradually degrade performance, reduce system lifespan, and compromise reliability.
EVERFUSE PPTC Devices
EVERFUSE devices are among the industry’s smallest, surface-mount, self-resettable overcurrent protection fuses. They utilize positive temperature coefficient (PTC) material that rapidly increases in resistance (and temperature) when exposed to excessive current. Once the fault is cleared, the device cools down and returns to its low-resistance state, automatically restoring normal circuit operation.
Current Limiting Module (CLM)
The CLM is a compact, surface-mount device designed to protect circuits from both overcurrent and overcharge conditions. It integrates a fuse element with a resistive heating element, which can be paired with an IC or FET for voltage detection. When an overvoltage condition is detected, the heating element activates, generating heat to trigger the fuse and interrupt current flow — effectively isolating the fault.

The eFuse is an integrated circuit (IC) that delivers advanced protection for power systems and sensitive equipment. Using an internal MOSFET, it combines multiple safeguards — including overvoltage, overcurrent and overtemperature protection — into a single compact solution. This integration simplifies circuit design while enhancing control, accuracy, and response times, resulting in safer and more reliable system operation.
