m271 1 form a solid state rela y the m271 is a bi-directional, single-pole, single-throw, norma lly open multipurpose solid-state relay in a miniature 4-pin smal l outline package. it is designed to be a cost-effective replacement of reed relays in low voltage applic ations. the relay consists of an integrated circuit that drives two rugged source-to-source enhancement ty pe dmos transistors - optically coupled to a light emitting diode . the output mos transistors are protected with free-wheeling diodes that can handle up to 1.5a of inrush current, making the relay i deal for switching lamps and highly inductive loads. description features applications options/suffixes* schematic diagram absolute maximum ratings* approvals ultra miniature 4-pin small outline package ? low input control power consumption (3ma typ) ? 10 ohms maximum on-resistance ? 60v load voltage rating ? 125ma maximum continuous load current ? high input-to-output isolation (1500v min) ? long life/high reliability ? reed relay replacement ? ? ? ? ? ? -tr note: suffixes listed above are not included in marking on device for part number identification. parameter unit min typ max storage temperature c -55 125 operating temperature c -40 85 continuous forward current ma 50 peak forward current (1us) a 1 reverse input control voltage v 5 output power dissipation mw 400 *the values indicated are absolute stres s ratings. functional operation of the device is not implied at these or any conditions in excess of those defined in electrical characteristics section of this document. exposure to absolute ratings may cause permanent damage to the device and may adversely affect reliability. ul / c-ul approved (file # e201932) ?
