Vishay Intertechnology low input current optocouplers in SOP-4 Mini-flat package

Thursday, 18 October, 2012 | Supplied by: Braemac Pty Ltd


Vishay Intertechnology’s VOM617A and VOM618A series of optoelectronics with low input current optocouplers and phototransistor outputs feature low input currents of 1 mA (VOM618A) and 5 mA (VOM617A) in the compact SOP-4 mini-flat package. This saves 30% PCB space over the DIP-4 package.

Both models in the series each offer nine different current transfer ratio (CTR) ranges from 40 to 600%, providing designers with increased flexibility. They are designed for isolated feedback loops, I/O isolation and isolation in switchmode power supplies, AC adapters, motor drivers, solar inverters, networking switches, telecom line cards and home appliances. The optocouplers protect equipment users from electrical shocks and protect the microprocessors within these systems from being damaged by voltage spikes.

The devices are also known as optoisolators and feature a GaAs infrared emitting diode that is optically coupled to a silicon phototransistor. The SOP-4 package provides a 3750 VRMS isolation voltage rating and creepage and clearance distance of ≥5 mm. The optocouplers are moulded using an eco-friendly ‘green’ compound and are RoHS-compliant and in accordance with WEEE 2002/96/EC.

They are certified to UL, CSA, VDE, FIMKO and CQC safety standards. Samples and production quantities have standard lead times of four to six weeks.
