K3022PG

Overview

The K3022PG is a non-zero crossing phototriac output optoisolator manufactured by Vishay Semiconductor Opto Division. It features a single channel with a 6-pin DIP package designed for through-hole mounting. The device provides an isolation voltage of 5300 Vrms and supports a maximum input current of 80 mA. It offers a peak repetitive off-state voltage (VDRM) of 400 V and a minimum static dV/dt rating of 10 V/µs. The component utilizes isolation materials compliant with UL 94-VO standards and meets pollution degree 2 requirements under DIN/VDE 0110 and IEC 60664 regulations.

Feature Summary

• Non-zero crossing triac output configuration for precise phase control applications
• High isolation capability rated at 5300 Vrms for safety-critical circuits
• Robust off-state voltage handling with 400 VDRM specification
• Compliant with UL 94-VO insulation material standards

Applications

• Solid-state relay designs requiring non-synchronized switching
• Industrial motor control systems
• AC power switching modules
• Phase angle control circuits

Procurement Notes

Verify the obsolete status of this specific part number before initiating procurement, as it may no longer be manufactured. Confirm that alternative components meet the required 400 VDRM and 5300 Vrms isolation specifications. Ensure the selected substitute maintains the non-zero crossing characteristic and DIP-6 package compatibility to preserve existing board layouts and circuit functionality without redesign.

Selection Notes

Select this component when non-zero crossing operation is required for AC load control rather than zero-crossing soft start. The 400 VDRM rating suits standard low-voltage AC applications. Verify that the 10 V/µs static dV/dt rating is sufficient for the noise environment. The DIP-6 package facilitates manual assembly or wave soldering processes in legacy manufacturing setups.

Part Context

This device belongs to Vishay's family of phototriac output optocouplers designed for industrial isolation. Unlike zero-crossing variants, this model triggers immediately upon LED activation, making it suitable for dimming and precise timing applications. The 6-pin DIP form factor ensures compatibility with standard PCB footprints used in older equipment designs.

Replacement Considerations

Public sources indicate the K3022PG is obsolete. Substitutes must match the non-zero crossing feature, 400 VDRM, and 5300 Vrms isolation. Verify pinout compatibility with the original DIP-6 footprint to avoid hardware modifications.
