On March 25, 2025, Diodes Incorporated (Nasdaq: DIOD) announced the launch of its first series of advanced Indium Antimonide (InSb) Hall element sensors, designed for rotation speed detection and current measurement across a variety of consumer and industrial applications. This strategic introduction aims to meet the growing market demand for high-sensitivity InSb Hall sensors packaged in industry-standard formats, specifically the 4-pin SOT23-4 and SIP-4 packages.

2. Target Applications

The new InSb Hall sensors are versatile, catering to consumer applications such as laptops, mobile phones, and joysticks, as well as motors utilized in various home appliances. In industrial settings, these sensors are ideally suited for position encoders and the commutation of brushless motors and fans. Their design reflects Diodes’ commitment to enhancing performance and reliability in critical sensing applications.

3. Sensor Specifications

AHE300 InSb Sensor

The AHE300 sensor offers Hall output voltage (VH) classifications ranging from C-G, providing a voltage output between 168mV and 370mV. It operates effectively within a temperature range of -40°C to +110°C and is packaged in a SIP-4 (Type MA) format. This sensor is competitively priced at $0.18 for 500-piece quantities, making it an attractive option for manufacturers looking for cost-effective yet high-performance solutions.

AHE10x Devices

In contrast, the AHE10x series supports higher output voltage classifications (C-H), with VH reaching up to 415mV. These devices are operational over a wider temperature range of -40°C to +125°C, which allows for robust performance in harsher thermal environments. The AHE10x sensors are supplied in SOT23-4 packages with various height options (A, B, C) and are priced at $0.10 for 3,000-piece quantities, enhancing their appeal for high-volume production needs.

4. Enhanced Sensitivity and Resolution

Both sensor series feature ultra-high sensitivity, enabling reliable operation even in the presence of weak magnetic fields. The low offset voltage, ranging from 5mV to 7mV, provides the necessary resolution for high-accuracy detection capabilities, further strengthening the sensors' appeal to a wide range of applications.

5. Commitment to Customer Needs

Diodes Incorporated continues to leverage its extensive portfolio of analog and discrete power solutions alongside innovative packaging technologies. By focusing on application-specific products and solutions-oriented sales strategies, the company aims to solidify its position as a premier provider in high-volume, high-growth markets.

6. Conclusion

The introduction of these advanced InSb Hall element sensors marks a significant development for Diodes Incorporated, reinforcing its role in delivering cutting-edge semiconductor solutions. As the demand for high-sensitivity sensing technologies continues to grow, Diodes is poised to meet the needs of both consumers and industry professionals alike with its latest offerings.
