LEISTER TRIAC SWITCH 25A/800V 114.692
Product Name
Leister 114.692 TRIAC SWITCH 25A/800V
Brief Description
A TRIAC (TRIode for Alternating Current) is a three-terminal semiconductor switching device designed to control the flow of electricity in AC circuits. The Leister 114.692 is a specific replacement part, rated for 25 Amperes and 800 Volts, commonly used in Leister hot air tools like the TRIAC S, ST, and AT models. It functions as a bidirectional switch, allowing it to conduct current in both directions of an AC supply.
Popular Applications & Uses
- Controlling AC power in various electrical applications.- Motor speed control (e.g., in fans).- Lamp dimming circuits.- Temperature regulation in industrial applications.- As a replacement part in Leister hot air tools for plastic welding, shrinking, and molding.- Switching high voltage loads, often controlled by microcontrollers via opto-couplers.
Industries that Commonly Use It
- Construction/ Building Services- Electrical Services or Products- General Manufacturing- Plastic Fabrication- Flooring Installer or Manufacturer- Cladding- Tarp, Fabric, Awning Manufacturing- Sign & Display
Special and Unique Features
- Bidirectional switching capability, ideal for AC circuits.- Can be triggered by both positive and negative gate pulses.- High current and voltage ratings (25A/800V).- Often used in conjunction with opto-couplers for isolated control by microcontrollers.- Robust construction for demanding applications.
Key Properties
- Type: TRIAC (Triode for Alternating Current)- Current Rating: 25 Amperes- Voltage Rating: 800 Volts- Function: Bidirectional AC switch- Component: Semiconductor device- Application: Power control and switching in AC systems
Surface Compatibility
Not applicable as this is an electronic component, not a surface-applied product. It is compatible with electrical circuits and systems requiring AC power control.
Known backups / known substitutes
- Other TRIACs with similar voltage and current ratings (e.g., BTA24-800BWRG).- SCRs (Silicon Controlled Rectifiers) can be used, but they are unidirectional and require two in inverse parallel for AC control, increasing complexity.- MOSFETs or IGBTs can be used for switching, especially with a diode bridge for AC, but they have different characteristics regarding voltage, current, and frequency handling compared to TRIACs for AC line-rate switching.- Solid-state relays (often incorporate TRIACs or similar switching elements).- Mechanical relays (though less precise and can generate heat).
Comparison Note
TRIACs are particularly well-suited for AC power control due to their bidirectional switching capability and ability to be triggered by both positive and negative gate pulses, making them simpler for AC applications compared to using two SCRs or a MOSFET with a bridge rectifier. They are robust for high voltage and current AC switching at lower frequencies. While MOSFETs and IGBTs offer advantages in high-frequency switching and specific voltage/current ranges, TRIACs remain ideal for many line-rate AC control applications like dimmers and motor speed controllers.
