LH1522AB/ AAC/ AACTR Document Number 83821 Rev. 1.3, released on 26-Oct-04 by Vishay Semiconductors. This document describes the features and characteristics of the LH1522AB/ AAC/ AACTR dual channel solid state relay, including current limit protection, isolation test voltage, typical RON value, load voltage, load current, high surge capability, clean bounce free switching, low power consumption, etc.
The LH1522AB is a dual‑channel, 1‑Form‑A solid‑state relay (SSR) that replaces electromechanical relays in telecom and industrial control applications. It uses a GaAlAs LED for actuation and monolithic MOSFET switches, offering isolation, current‑limit protection and low power consumption.
The datasheet lists absolute maximum ratings, typical electrical characteristics such as 5300 VRMS isolation voltage, 10 Ω on‑resistance, 200 V load voltage and 120 mA load current, as well as mechanical data, recommended operating conditions and certification approvals (UL1577, CSA, BSI, DIN EN).
