Product Overview
Vishay CQY80NG is a single-channel optocoupler combining a gallium arsenide infrared LED with an NPN phototransistor output. The "G" suffix designates the 10.16 mm wide DIP-6 leadform, providing increased creepage and clearance distances for reinforced isolation designs. This wider footprint is critical in applications that must meet higher safety spacing requirements without redesigning the PCB.
Designed for industrial power supplies and microprocessor interfaces, the CQY80NG offers reinforced isolation performance with an accessible base pin for output bias control. With the CQY80 series officially moved to End-of-Life status, original Vishay stock in the 10.16 mm package is increasingly sought after for maintenance and certified repair work.

Frequently Asked Questions
What does the "G" suffix indicate?
The "G" denotes the 10.16 mm wide DIP-6 leadform. This provides increased creepage and clearance compared to standard 7.62 mm packages and is required in many reinforced isolation designs.
Is this a high-speed optocoupler?
No. With typical turn-on and turn-off times in the microsecond range, it is intended for DC and low-frequency isolation rather than high-speed digital logic.
What is the purpose of the base pin?
Pin 6 provides access to the phototransistor base, allowing external biasing to adjust switching characteristics or stability in noisy environments.
Is this still in active production?
The CQY80 series has been moved to End-of-Life status. Availability is limited to remaining inventory and secondary market stock.
Can a standard narrow DIP optocoupler replace this?
Not without reviewing PCB spacing and safety certification requirements. The 10.16 mm leadform is often specified specifically for reinforced isolation compliance.
When a design calls for reinforced isolation and the board was laid out for a 10.16 mm footprint, there is no easy substitute. This CQY80NG keeps legacy power and interface circuits compliant and intact.
