LH1540AABTR Description

Short technical summary and product information.

The Vishay Dale LH1540AABTR is a 1 Form A (SPST normally open) Solid-State Relay, suitable for applications requiring reliable switching without the bounce of electromechanical relays. It utilizes a GaAlAs LED for actuation and MOSFETs for the output switch.

Key electrical specifications include an isolation test voltage of 5300 VRMS, a typical on-resistance of 22 Ω, and a maximum load voltage of 350 V. The device can handle a continuous load current of 120 mA in AC/DC configuration or up to 250 mA in DC-only configuration. Its SSR output power dissipation is rated at 550 mW continuously.

Operating within an ambient temperature range of -40 °C to +85 °C, the LH1540AABTR is designed for demanding environments. It is available in SMD-6 and DIP-6 package types, with options for tube or tape and reel packaging.

Applications include general telecom switching, security equipment, instrumentation, and industrial controls. Agency approvals include UL, cUL, DIN EN 60747-5-5 (VDE 0884), and FIMKO.
