概述

Description

AQY412EHA is Panasonic’s single-channel photomos relay (optically isolated MOSFET output) in the AQY family. It uses an input LED to optically actuate two MOSFETs on the output side, providing galvanic isolation between input and output.
Key points:
- 1-channel optically isolated switch; MOSFET output can switch DC and AC loads.
- High input-to-output isolation for safety and noise immunity.
- Input side requires only a small drive current (LED forward current in the few mA range) to turn on; off-state leakage is small.
- Output side offers bidirectional MOSFET switching with low on-resistance when on (no mechanical wear, fast switching).
Typical uses:
- Signal isolation for microcontrollers and logic circuits
- Interface between low-voltage controllers and higher-voltage loads
- Industrial, automotive, and consumer electronics where galvanic isolation is desired
For exact electrical specifications (Vds, If, Id, Rds(on), isolation voltage, package), refer to the AQY412EHA datasheet.

Features

AQY412EHA is a Panasonic PhotoMOS relay (MOSFET output). Key features:
- 1-channel, Form A (normally open) output
- MOSFET output with no mechanical contacts (no bounce, long life)
- High input–output isolation (several kV RMS typical)
- Low input drive current (LED-driven)
- Quick switching with very low on resistance and leakage when OFF
- Small surface-mount package (8-pin) and RoHS compliant
- Wide operating temperature range
Note: exact electrical ratings (Vds, Id, Ron, leakage, etc.) vary by part; consult the datasheet for the precise values of AQY412EHA.

Package

AQY412EHA is a Panasonic PhotoMOS relay in an 8-pin surface-mount package (SOP-8, gull-wing).

Pinout

AQY412EHA has 4 pins. Function: it’s a PhotoMOS (solid‑state) relay — a single‑pole, normally‑open (1 Form A) optically‑isolated device. Two pins are the LED input (anode, cathode) and two are the MOSFET output terminals (isolated source/drain) used to switch AC/DC loads.

Manufacturer

- Manufacturer: Panasonic (Panasonic Corporation, via its Semiconductor Solutions division; AQY series PhotoMOS relays).
