Vishay SFH610A-2 4-Pin DIP Optocoupler 60mA 5.3kV

The Vishay SFH610A-2 4-Pin DIP Optocoupler is a 1-channel phototransistor output optocoupler with a 5.3 kV isolation voltage, designed for reliable signal isolation between two electrically isolated circuits.

Overview

The SFH610A-2 uses a gallium arsenide (GaAs) infrared diode emitter that is optically coupled to a silicon planar phototransistor detector. This arrangement transmits signals across electrically isolated circuits. The device provides a high current transfer ratio (CTR), low coupling capacitance and a high isolation voltage.

Key Features

• Excellent CTR linearity relative to forward current
• Low saturation voltage
• Fast switching times
• Designed to maintain stable operation across a range of temperatures
• Low CTR degradation over time
• High immunity to common-mode interference, suitable for noisy electrical environments

Package and Insulation

The optocoupler uses an end-stackable DIP package with a standard 2.54 mm pin spacing, making it straightforward to integrate into a variety of circuit board designs. It complies with the reinforced insulation standards of IEC 60950 (DIN VDE 0805) for operational voltages up to 400 VRMS or DC, with creepage and clearance distances greater than 8 mm.

Applications

Suitable for a variety of electronic applications that require dependable electrical isolation and signal integrity, the SFH610A-2 is a suitable choice for circuits that need signal transfer between isolated sections.

Choose the Vishay SFH610A-2 4-Pin DIP Optocoupler when you need a 4-pin DIP phototransistor optocoupler with a 63% minimum CTR and a 5.3 kV isolation rating.
