ELR0223

Everlight Elec · Solid State Relays (Triac Output) · DIP-8

ELR0223 from Everlight Elec, in a DIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 LED_CATHODE passive LED cathode (input side). Internally tied to pins 3 and 4. Return for the GaAs IR emitter; drive with I_F up to 60 mA (I_FT >= 10 mA typ to trigger the output triac). V_F ~ 1.2 V @ 20 mA.
2 LED_ANODE passive LED anode (input side). Forward-drive the GaAs IR emitter through a current-limiting resistor. Max forward current 60 mA continuous, peak 1 A; reverse voltage max 6 V.
3 LED_CATHODE passive LED cathode (input side). Internally tied to pins 1 and 4. Duplicate pin for the emitter cathode.
4 LED_CATHODE passive LED cathode (input side). Internally tied to pins 1 and 3. Duplicate pin for the emitter cathode.
5 TRIAC_GATE passive Gate of the main output triac. Driven internally by the photo-triac detector; external snubber / gate resistor may be connected here for noise immunity. Rated for AC line switching (V_DRM = 600 V).
6 T1 passive Main output triac terminal 1 (MT1). AC line switching terminal. On-state RMS current 0.3 A (ELR0223), non-repetitive surge current 3 A, holding current I_H <= 25 mA.
8 T2 passive Main output triac terminal 2 (MT2). AC line switching terminal. V_DRM = 600 V peak off-state; V_TM <= 2.5 V @ I_TM(max).
