VOR1003M4T is an industrial-grade relay with a 1 Form A (single-pole normally-open) contact.
On the output side there are back-to-back mosfets allowing ac or dc to be switched.
Typical output-side figures are: 0.7Ω Rds(on), 500μs Ton, 100μsToff and <1μA leakage. These switching times are with 10mA drive and a 200Ω 50mA load.
On the front-end, the device will be on with 5mA flowing through the input LED and off with 0.4mA, according to the data sheet.
Isolation between the input and output is rated at 3,750Vrms.
5A load current is only allowed up to 20°C, above which capacity linearly declines to 1A at 85°C.
A similar solid-state relay, VO1401AEFTR, was introduced at the same time, rated at 550mA and 60V.
“With their high current capability, the devices released today are ideal for replacing electromechanical relays with contactless optical relays that provide vibration-proof switching,” claimed Vishay.
The SOP-4 package has a 7 x 4.3mm footprint.
