M271

• Product Introduction

illustrate

The M271 is a bidirectional, single-pole, single-throw, normally open in a small form factor package with 4 multi-purpose miniature solid-state relay pins. It is designed to be a cost-effective alternative to spring relays in low voltage applications. The relay consists of an integrated driver circuit, two robust source-to-source-enhanced DMOS transistors – opto-coupled to a light-emitting diode. The output MOS transistor is protected with freewheeling diodes that can handle inrush currents up to 1.5A, making lamp switching relays ideal for highly inductive loads. Features On-resistance (10 ohms max) 125mA load current Input control Low power consumption (3mA typical) Micro 4-pin SOP package High input-to-output isolation (1.5kV min) Solid-state reliability RoHS compliant/lead-free/REACH compliant Applied Telecom Switching Prompt/Loop Control PCMCIA Modules Multiplexers Meter Reading Systems Data Acquisition Medical Devices Battery Monitoring Home/Safety & Assurance Systems
