Overview

The PVT312LS-TPBF is a single-pole, normally open solid-state photovoltaic relay designed to switch AC and DC loads up to 250V. It utilizes a GaAlAs light-emitting diode input integrated with a photovoltaic generator to drive a HEXFET power MOSFET output stage. This 6-pin surface-mount device features integrated current limiting to protect against circuit overloads.

Why Choose This Part

This photorelay offers significantly higher reliability and longer life than electromechanical relays because it has no moving parts to wear or arc. It provides 4000Vrms input-to-output isolation and includes an internal current-limiting circuit that prevents damage during fault conditions. The surface-mount DIP gull-wing package is optimized for automated assembly and high-density PCB layouts.

Applications

Telecom Hook Switch
Functions as an electronic On/Off hook switch for telephone line interfacing.
Ring Injection
Reliably handles ring signal injection in telecommunication systems due to its 250V load rating.
Industrial Control Signal Switching
Used for general-purpose switching of low-level signals where bounce-free operation is required.
Ground Start Circuitry
Acts as a reliable interface for ground start signaling in PBX and central office equipment.

Getting Started

When designing with this relay, ensure the input LED current is at least 5mA for reliable switching, while not exceeding the maximum rated forward current. No external snubber is typically required for DC loads, but peak load voltage must stay below 250V. Refer to the footprint specifications for the 6-pin SMD gull-wing package to ensure proper solder reflow profiles.

Also Consider

AQW214EH Panasonic - Offers a dual-channel (2 Form A) configuration in an 8-pin package if multiple isolated switches are needed.
CPC1035NTR IXYS Integrated Circuits Division - A more compact 4-pin SOP version for space-constrained applications that do not require current limiting.
