M251 Datasheet | Solid State Optronics

1 Form A Solid State Relay DESCRIPTION The M251 is a bi-directional, single-pole, single-throw, normally open solid-state relay. It offers low on-resistance and high load current ratings in an ultra miniature 4 pin SOP package. The relay consists of an AlGaAs infrared LED, optically coupled to an IC, which in turn drives two back to back enhancement type DMOS transistors. Features - Low on-resistance (1 ohm MAX) - High Load Current Rating (400mA continuous MAX) - Low input current (2.5mA MAX) - High input-to-output isolation (1500Vrms) - Ultra Miniature 4 pin SOP package - Long life / high reliability OPTIONS/SUFFIXES- - -TR Tape and Reel (2,000 pcs / reel) NOTE: Suffixes listed...
