It is outstanding for a high magnetic sensitivity and low temperature coefficients. The 0.35 × 0.35 mm2 chip is mounted onto a non-magnetic leadframe. The active area is placed approx. 0.45 mm below the surface of the package.

The by-pass circuit-breaker shall not be opened before turning on the power source. This is to avoid damage to the Hall sensor due to power peaks. 1) Thermal conductivity chip-ambient when mounted on alumina ceramic 15 mm × 17 mm × 0.7 mm 2) AQL: 0.65 Semiconductor Group 2
