Product type
GTO Thyristors, or Gate Turn-Off Thyristors, are semiconductor devices used primarily for controlling power in various applications. They are made from silicon and are designed to handle high voltage and current, allowing them to switch on and off in response to gate signals. GTO Thyristors are typically utilized in applications requiring efficient power control, such as in motor drives, power inverters, and industrial heating systems.
| Voltage rating | Up to 4,000 volts |
| Current rating | Up to 3,000 amperes |
| Gate trigger current | Typically 100 to 500 mA |
| Operating temperature range | -40°C to +125°C |
| Package types | TO-220, TO-247, and custom packages |
When selecting GTO Thyristors, consider the voltage and current ratings required for your application. It's important to specify the gate trigger current and the operating temperature range to ensure compatibility with your system. Additionally, inquire about package types to ensure proper integration into your design. If applicable, check for any necessary certifications or compliance with industry standards.
