Product Overview
EL_EL303X-P5-_EL304X-P5-_EL306X-P5-_EL308X-P5- is an EVERLIGHT zero-cross triac driver photocoupler in the LED category. The device function is defined as a GaAs infrared emitting diode optically coupled to a monolithic silicon zero-voltage-crossing photo triac, supporting isolated triggering where zero-voltage-crossing behavior is required.
The family includes voltage classes with 250 V peak breakdown for EL303X(P5), 400 V for EL304X(P5), 600 V for EL306X(P5), and 800 V for EL308X(P5). Output ratings include 1 A maximum peak repetitive surge current, 100 mA maximum on-state RMS current, 3 V maximum peak on-state voltage, and 500 µA maximum leakage in the inhibited state.
The package is a 5-pin DIP optocoupler format using a standard DIP-6 body with pin 5 cut. Lead-form options include M wide lead bend with 0.4 inch spacing, S surface mount, and S1 low-profile surface mount. Assembly data includes 260 °C soldering for 10 seconds and a reflow profile with 150 to 200 °C preheat, 217 °C liquidus, 260 °C peak temperature, and up to 3 reflow cycles.

Procurement Notes
When requesting a quote for EL_EL303X-P5-_EL304X-P5-_EL306X-P5-_EL308X-P5-, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For LED and optoelectronic sourcing, brightness bin, wavelength or color temperature bin, forward voltage range, viewing angle, moisture sensitivity level and soldering process limits may affect final selection, availability and lead time.
