AOTE SEMI
Optocouplers and galvanic-isolation components for industrial electronics and power systems
About the manufacturer
Taiwan Aote Semiconductor Technology Co., Ltd. is a semiconductor manufacturer specializing in optocouplers and solutions for galvanic signal isolation. The company was founded in 2018, with its R&D facilities located in Taichung, Taiwan. Its development team includes engineers with experience gained at major semiconductor companies.
AOTE develops its own optoelectronic and mixed-signal solutions, focusing on components that safely transfer signals between circuits operating at different electrical potentials. Its portfolio includes transistor-output optocouplers, high-speed optocouplers, photo relays, thyristor-output optocouplers, Darlington devices and optocouplers designed for IGBT gate driving.
The manufacturer develops pin-compatible alternatives for widely used optocoupler families employed in industrial and power electronics. AOTE also states compliance with RoHS and REACH requirements and operates ISO 9001 and ISO 14001 management systems.
Applications
AOTE optocouplers are used wherever the control section must be electrically isolated from power circuitry or electrically noisy environments. Typical applications include:
- switch-mode power supplies and converters – feedback and primary-to-secondary isolation
- industrial automation – isolation of PLC inputs, outputs and I/O modules
- drives and inverters – isolation of control signals and gate-drive circuits
- measurement equipment – protection of signal paths against potential differences and transients
- smart-home and IoT devices – separation of mains circuitry from low-voltage electronics
- automotive electronics – isolated control and power-management circuits
- medical and industrial equipment – improved safety and noise immunity
AOTE SEMI products available from Maritex
The AOTE range available from Maritex includes optocouplers designed for galvanic signal isolation in electronic equipment, power supplies and automation systems.
Available product groups include:
- transistor-output optocouplers
- DIP/SMD devices for PCB assembly
- optocouplers for power-supply feedback loops
- components for isolation of digital and analog control paths
One example available from Maritex is the PC817C, a single-channel transistor-output optocoupler with 5 kV isolation voltage. Devices of this type are widely used in power-supply feedback, control circuits and industrial input/output interfaces.
When selecting an optocoupler, key parameters include isolation voltage, CTR, collector-emitter voltage, operating-temperature range, package/mounting style and the required signal speed.
