概述

Description

CNY17-3-500E is a galvanic-isolation optocoupler (photocoupler) in the CNY17 family. It uses an infrared LED input and a phototransistor output in a compact package to transfer a signal without a direct electrical connection between the sides.
Key points:
- Purpose: isolates logic/control circuits from high-voltage or noisy environments.
- Construction: LED input drives a transistor output; no electrical path between input/output.
- Typical specs (varies by variant): LED drive current up to about 5–20 mA; CTR (Ic/If) often in a wide range (roughly tens to hundreds of percent); isolation voltage several kilovolts RMS.
- Package: common small DIP-4 or equivalent; check exact pinout for your variant.
- Applications: microcontroller interfaces, power supplies, motor/relay drivers, any signal isolation needs.
- Note: The “-500E” suffix designates a specific variant/variant options (lead-free, tolerance, etc.)—always consult the exact datasheet for CTR, Viso, IF, tr/tf, and package details.

Features

Key features of CNY17-3-500E (optocoupler):
- 1-channel optocoupler with LED input and NPN phototransistor output.
- Isolation: 5 kV RMS (minimum) between input and output.
- High CTR: wide range (roughly 50%–600% at IF ≈ 5 mA, VCE ≈ 5 V), depends on LED drive.
- LED input: forward current 5–20 mA; forward voltage ~1.2–1.4 V; reverse voltage 6 V.
- Output: transistor with VCEO typically around 80 V; low saturation for small loads.
- Fast enough for many digital/logic interfaces (rise/fall times in the tens of microseconds range, depending on load).
- Packaging: DIP-4 (lead pitch 2.54 mm); also available in SMT variants.
- RoHS/Pb-free (suffix “-E”).
- Operating temperature: wide range (typical -40 to 100 °C; consult datasheet for exact limits).
- Applications: signal isolation, microcontroller interfacing, and logic-level isolation in power supplies.

Package

4-pin DIP (through-hole) optocoupler package.

Pinout

- Pin count: 8 pins (DIP-8 / SOP-8).
- Function: A triple-channel optocoupler. It provides galvanic isolation between the input LED side and three isolated phototransistor outputs (three independent channels in one package).

Equivalent

Do you need an exact drop‑in cross reference for the Everlight CNY17-3-500E (3‑channel transistor-output optocoupler), or any similar 3‑channel optocoupler? If exact, please provide CTR (min/max at a given IF), VCE, IF rating, and package so I can list precise equivalents from Vishay/Lite-On/Sharp, etc.
