Product details

Hall latch for high-temp automotive sensing

The TLE4935LHALA1 is an Infineon magnetic switch latch from the Automotive series, qualified to AEC-Q100. It switches on at a south-pole field of 20 mT and releases at -20 mT, with an open-collector output rated for 100 mA continuous.

Rated for junction temperatures from -40°C to 150°C, this latch handles under-hood and transmission environments where commercial parts fail. That junction ceiling is 25°C higher than the TLV4961-1TBXALA1 (125°C TA), which matters when the sensor sits near an exhaust manifold.

Available in Cut Tape and Tape & Box packaging for through-hole insertion.

Frequently asked questions

What is the closest functional second-source for TLE4935LHALA1?

The TLE4905LHALA1 is a sibling in the same TLE series with the same supply voltage (3.8 V) and through-hole package, but it is a unipolar switch (18 mT trip, 5 mT release) rather than a latch. For a latch with a wider temperature range, the TLE4935LHALA1's -40°C to 150°C junction rating exceeds the TLV4961-1TBXALA1's 125°C ambient limit.
