Optocouplers boast low AC input current of ±5mA, ±1mA

Vishay Intertechnology recently unveiled two optocouplers with phototransistor output. The devices come in SSOP-4 mini-flat packages with double-moulded construction, saving more than 60 per cent board space compared to 4-pin DIPs and improving high-voltage performance compared to coplanar constructions.

With low AC input current of ±5mA (VOS627A) and ±1mA (VOS628A), the optocouplers can be used for programmable logic controllers, industrial control systems, and office automation applications. The devices protect equipment users from electrical shocks and safeguard microprocessors within these systems from being damaged by voltage spikes.

The two half-pitch mini-flat series are available with a variety of CTR (current transfer ratio) ranges from 50 per cent to 600 per cent. Each device integrates a GaAs infrared emitting diode optically coupled to a silicon planar phototransistor detector. Their 4-pin package provides an isolation voltage rating of 3750V RMS, a half lead pitch of 1.27mm (50 mils), and a creepage and clearance distance of ≥5mm.

Samples and production quantities are available now, with standard lead times of 4 to 6 weeks. Prices start at $0.58 each in lots of 1000 units.
