M251 Datasheet, PDF (1/5 Pages) Solid State Optronic – Low on-resistance (1 ohm MAX)
M251
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 above are not included in marking on
device for part number identification.
