VISHAY ILQ620 AC Input-Transistor Output Optocoupler 4-Element
The VISHAY ILQ620 is a high-performance, multi-channel optocoupler designed for AC voltage detection applications. This device features transistor output channels with inverse parallel GaAs IRLED emitters and high-gain NPN silicon phototransistors, providing reliable electrical isolation and signal transfer.
Product Features
Four-element transistor output optocoupler suitable for AC voltage detection
Identical channel-to-channel footprint for easy integration
High collector-emitter voltage, BV CEO = 70 V
Double molded insulation with over/under leadframe optical coupling for withstand test voltage of 5300 V RMS
Low power dissipation with low I F guaranteed CTR CEsat in ILQ620GB models
Enhanced electrical noise immunity by eliminating phototransistor base connection
The ILQ620 series is certified with UL1577, cUL, FIMKO, and DIN EN 60747-5-5 (VDE 0884) approvals, ensuring safety and reliability for industrial applications. The device supports high isolation voltage and offers excellent electrical noise immunity, making it suitable for AC voltage detection in industrial control systems.
For more detailed electrical characteristics and application information, please refer to the datasheet.
Note: The datasheet was not processed; please search the internet for the part number ILQ620 for more details.
I'm particularly impressed with how carefully the header pins are packed for the RP2350-PiZero, they arrived in perfect condition without any bent pins, which has been a persistent issue with other competitors. This attention to packaging detail really stands out.
I also received the latest A4 revision of the RP2350, which shows you maintain current inventory, that's really valuable for customers who want the most up to date components.
The delivery was quick and hassle free throughout. I'll definitely be recommending you to others!
App feedback: The discounts offered through the app are a nice bonus, but the component search function could be improved to match the ease of use on the website version. The rest of the app functions work well.
