SMA4217
1 Form A 60V / 5Ω MOSFET Output Solid State Relay
Description
The SMA4217 is a bi-directional, single-pole, single-throw, normally open multipurpose solid-state relay in a miniature 4-pin small outline package.
It is designed to be a costeffective replacement of reed relays in low voltage applications.
The relay consists of an AlGaAs LED, optically coupled to a high performance Photo Diode Array (PDA), which in turn drives two low on-resistance, rugged source-to-source enhancement type DMOS
transistors.
The output MOS
transistors are protected with freewheeling diodes that can handle up to 1.
5A of inrush current.
The SMA4217 comes standard in a 4 pin SOP package.
