EL814S1(TD)

Transistor, Photovoltaic Output Optoisolators Overview

The EL814S1(TD) is a single-channel phototransistor output optocoupler from Everlight Electronics. It features an AC/DC input configuration with two infrared emitting diodes connected in inverse parallel, optically coupled to an NPN phototransistor detector. The device provides high isolation voltage of 5000 Vrms and supports a collector-emitter breakdown voltage of 80V. It operates within a temperature range of -55°C to 110°C and is housed in a surface-mount 4-pin package.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• AC input response capability due to dual inverse-parallel infrared LEDs
• High isolation voltage between input and output terminals
• Wide operating temperature range for industrial environments

Transistor, Photovoltaic Output Optoisolators Applications

• Digital logic signal transmission and conversion
• Power supply control and switching circuits
• Electrical insulation isolation between circuits and systems

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (TD) indicates the low-profile surface mount lead form and tape & reel packaging configuration. Confirm RoHS compliance status and UL/VDE recognition numbers match current regulatory requirements for your target market before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when AC input detection is required without external rectification. Ensure the 80V collector-emitter voltage rating exceeds the maximum load voltage. Verify that the surface-mount footprint matches the PCB design constraints and that the thermal management supports the specified operating temperature range.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the EL814 series, which utilizes a compact dual-in-line or surface-mount package containing an infrared emitter and phototransistor. The series is designed for general-purpose isolation applications requiring reliable electrical separation between input and output sides while maintaining signal integrity across varying temperature conditions.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Equivalent parts include EL814S1(TB) and EL814S1(TA), differing primarily in packaging style. Verify pinout compatibility and ensure the replacement maintains the same 5000 Vrms isolation rating and 80V output voltage specification.
