April 8, 2025 /SemiMedia/ — Diodes Incorporated recently introduces its first series of advanced InSb Hall element sensors for rotation speed detection and current measurement in consumer applications such as laptops, mobile phones, joysticks, and in motors found in various home appliances. In industrial applications, they are designed for use in position encoders and commutation of brushless motors and fans. The development of these devices addresses the market demand for greater availability of high-sensitivity InSb Hall sensors in the industry-standard 4-pin SOT23-4 and SIP-4 packages.

The AHE300 InSb sensor supports Hall output voltage (VH) classifications C-G, which range from 168mV to 370mV. The AHE10x sensors support classifications C-H and deliver VH up to 415mV. The ultra-high sensitivity of these sensors allows them to operate reliably even in the presence of weak magnetic fields across a broad range of applications. Furthermore, the low offset voltage (5mV to 7mV) of these sensors achieves the level of resolution required to deliver high-accuracy detection capabilities.

The AHE300 sensor operates in the -40°C to +110°C temperatures range, is housed in a SIP-4 (Type MA) package, and is available at $0.18 in 500-piece quantities.

The AHE10x devices operate over a wider temperature range (-40°C to +125°C), making them sufficiently robust for use in harsh thermal environments. For application flexibility, they are supplied in SOT23-4 packaging with various height options (A, B, C) and are available at $0.10 in 3,000-piece quantities.
