SMA4115
1 Form A 60V / 75mΩ DC MOSFET Output Solid State Relay
Description
The SMA4115 is a DC, single-pole, single-throw, normally open solid-state relay in a 4 pin single inline package. The relay consists of an AlGaAs LED, optically coupled to a high performance Photo Diode Array (PDA), which in turn drives one low on-resistance, rugged source-to-source enhancement type DMOS transistor. The SMA4115 has an extremely low on resistance of 50m (TYP) and a very high continuous load current rating of up to 3.4A. The combination of low on-resistance, small package outline and high load current capabilities make the SMA4115 a unique, unparalleled solid state relay.
The SMA4115 comes standard in a 4 pin SIP package.
Applications
