The ELM3023 is a triac driver optocoupler by Everlight Electronics. It is designed to interface logic circuitry with equipment powered by AC line voltage. This device consists of an infrared emitting diode (IRED) optically coupled to a bilateral silicon switch, functioning as a triac driver.
Applications:
- Solid-state relays
- Industrial controls
- Lighting controls
- Motor controls
- AC power switching
Features:
- High isolation voltage (typically 5,000 Vrms)
- Peak blocking voltage of 400 V
- Low input trigger current
- High static dV/dt immunity
- UL and VDE recognized
Benefits:
- Provides electrical isolation between low-voltage control circuitry and high-voltage AC loads, enhancing safety and preventing equipment damage.
- Facilitates the control of AC loads using low-power DC signals from microcontrollers or other logic devices.
- Minimizes the required input current for triggering the triac, making it compatible with a wide range of control circuits.
- Offers robust performance in noisy industrial environments due to high dV/dt immunity.
- Complies with industry safety standards, ensuring reliable operation and regulatory compliance.
Additional details: The ELM3023 is available in a standard DIP-6 package. It is designed for through-hole mounting. The device's key electrical parameters include the LED trigger current (IFT), on-state voltage (VTM), and isolation voltage. This optocoupler is commonly used in applications requiring a safe and reliable interface between electronic control systems and AC-powered equipment.
