概述

Description

EL8176FWZ-T7 is a single-channel optocoupler (photocoupler) from Everlight, part of the EL817 family. It provides electrical isolation between input and output using an infrared LED (input) and a phototransistor (output).
Key points:
- Purpose: galvanic isolation for signal or feedback paths in power supplies, motor drivers, and microcontroller interfaces.
- Architecture: 1-channel, LED input driving a phototransistor output (NPN).
- Isolation: high-voltage barrier (typical ratings in the kilovolt RMS range, per datasheet).
- Packaging: 4-pin device in a tape-and-reel (T7) format for automated assembly; FWZ indicates package/lot code.
- Electrical behavior: current transfer ratio (CTR) depends on LED drive current and temperature; results vary with conditions (see datasheet for exact values and test conditions).
For exact electrical specs (IF, CTR, VCEO, parasitics) and recommended operating conditions, refer to the official EL8176FWZ-T7 datasheet.

Features

EL8176FWZ-T7 features:
- 1-channel optocoupler (LED input, phototransistor output)
- High input–output isolation (Viso up to 5 kV RMS minimum)
- Wide operating temperature: -55°C to +125°C
- RoHS compliant, Pb-free
- Package: FWZ SMD in Tape & Reel (T7) for automated assembly
- Output: NPN phototransistor suitable for logic/TTL interfaces
- Small footprint and good CTR for signal isolation
- Applications: microcontroller interfaces, power supplies, industrial control
Note: Refer to the datasheet for exact CTR, IF ratings, and timing specs.

Package

EL8176FWZ-T7 is an optocoupler in a 4‑pin DIP (DIP‑4) through‑hole package; the T7 suffix indicates tape‑and‑reel packaging.

Pinout

- Pin count: 4 pins
- Function: Optocoupler (photocoupler) with an LED input and NPN phototransistor output. Pin 1 = Anode, Pin 2 = Cathode (LED). Pin 3 = Emitter, Pin 4 = Collector (output transistor). Provides galvanic isolation between input and output.

Manufacturer

Manufacturer: Everlight Electronics Co., Ltd. (Everlight).
Kind of company: A Taiwan-based multinational that designs and manufactures optoelectronic components, including optocouplers, LEDs, infrared emitters/detectors, and related sensors, serving global markets.
