概述

Description

FODM217A is a photomos/optical isolator (photocoupler) used to provide galvanic isolation between input and output. It typically contains an infrared LED on the input side and MOSFET output on the other side, so driving the LED turns the output MOSFETs on and completes a load circuit without a direct electrical connection.
Key points:
- Single-channel, solid-state relay style device
- LED input drives a MOSFET output for isolated switching
- No mechanical contacts, good for long life and high-frequency switching
- Suitable for switching AC/DC loads depending on the output configuration
- Commonly used for isolated signal interfaces, microcontroller protection, measurement equipment, and power-supply control
For exact electrical specs (IF, VDS, RON, leakage, isolation voltage, switching times, and package type), refer to the datasheet for the specific FODM217A revision.

Package

FODM217A uses an 8-pin package: DIP-8 (through-hole). It is also available in an 8-pin SO-8 surface-mount version.

Pinout

FODM217A is an 8-pin device (DIP-8/SO-8) and is a 1-channel optocoupler with a MOSFET output. The input is an LED; the output is two MOSFETs connected back-to-back to provide isolated, bidirectional switching suitable for solid-state relay-style applications.

Manufacturer

Manufacturer: Fairchild Semiconductor (now part of ON Semiconductor).
What kind of company: A global semiconductor company that designs, manufactures, and markets integrated circuits, discrete semiconductors, and optoelectronic devices.

Application

FODM217A is a dual MOSFET optocoupler (Photomos) for galvanic isolation with load switching. Typical applications:
- Isolated switching of DC/low-voltage AC loads (relay replacement)
- Gate-drive isolation for power MOSFETs/IGBTs
- Isolated signal interfaces in industrial automation and instrumentation
- Power supplies and telecom equipment needing control/load-side isolation
- Safety-critical medical devices and consumer electronics requiring galvanic isolation
