K3010PG

Overview

The K3010PG is a single-channel Triac and SCR output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a gallium arsenide infrared-emitting diode optically coupled to a phototriac within a 6-lead plastic dual inline package (DIP). The device provides a high isolation voltage of 5300 Vrms and supports a peak off-state voltage of 250 V. It operates with a maximum RMS on-state current of 100 mA and an input forward current limit of 80 mA. The unit is certified by BSI, CQC, UR, and VDE, ensuring compliance with international safety standards for industrial applications.

Feature Summary

• High-voltage electrical isolation capability rated at 5300 Vrms between input and output circuits
• Non-zero crossing switching characteristic suitable for phase control applications
• Integrated phototriac output designed for direct triggering of external power triacs
• Certified for global safety standards including UL, VDE, and CQC approvals

Applications

• AC mains switching for resistive loads
• Heater control systems
• Triggering external triacs in inductive load circuits

Procurement Notes

Verify the specific package variant, as the K3010P series includes both through-hole DIP and surface-mount SMD options. Confirm that the non-zero crossing behavior aligns with the application requirements, as this differs from zero-crossing variants. Check certification marks against regional regulatory needs. Note that availability may vary due to product lifecycle status; verify current production status before finalizing design-in decisions.

Selection Notes

Select this component when high isolation voltage is required for controlling AC loads without zero-crossing synchronization. Ensure the external triac can handle the 250 V DRM rating. Verify that the 100 mA RMS current capacity meets the load requirements. Consider thermal management if operating near the upper temperature limits. Compare with other Vishay series members if different packaging or switching characteristics are needed.

Part Context

The K3010PG belongs to the K3010P(G) series of Triac and SCR output optocouplers. This family utilizes a gallium arsenide infrared LED coupled to a phototriac. The series is engineered for robust isolation in power control environments. Other variants in the series include different package styles such as standard DIP and surface-mount configurations, maintaining consistent electrical performance across the lineup.
