PHOTO MOS RELAY
-High Reliability: Stable on-resistance impedance
-High Insulation: The isolation voltage can exceed 5KV.
-Long Lifetime: No mechanical contacts, no switching wear.
-High Operation Speed: Working/release time is about 0.3ms.
-Other Advantages: Small size, low power consumption, low leakage current, bounce-free and noiseless.
SiC MOSFET & Schottky Diodes
(SiC) MOSFETs enable higher switching frequencies and reduce the size of components like inductors, capacitors, filters & transformers. Pairing SiC diodes with SiC MOSFETs creates a powerful combination of higher efficiency.SiC MOSFETs replace silicon devices to enable lower switching and conduction losses with higher blocking voltages and avalanche capability.
Personal computers and other electronic equipment constantly lose power when they operate. Power loss can be kept low by using high performance power semiconductors. High performance power semiconductor can realize saving energy for not only Personal Computers, but also Smartphones, Automotive application, Trains, and Electrical substations.
OPTOCOUPLER
-Excellent Electrical Isolation Performance: Complete electrical isolation between input/output terminals.
-Signal Unidirectional Transmission: Effectively block the connection between the circuit and the system to complete the signal transmission.
-Strong Anti-interference Ability: Ensure that the signal is not subject to electromagnetic interference in the transmission process.
-Fast Response Speed: Millisecond response speed, reduces signal attenuation.
-Simple Circuit Design: Easier to match various logic circuits.

(GaAs/InSb) HALL ELEMENT
-Gallium arsenide (GaAs) Hall elements offer a number of key advantages, including high sensitivity, low temperature drift, zero hysteresis, a magnetic field linear operating range up to 2T and other excellent characteristics.
-Indium antimonide (InSb) Hall elements offer ultra-high sensitivity, but their temperature characteristics are less favourable compared to GaAs Hall elements. Therefore, a constant voltage drive is typically used to ensure more stable temperature characteristics, making them suitable for DC brushless motors and closed-loop current sensors.
