Overview
The K3021P is a single-channel phototriac output optoisolator manufactured by Vishay Semiconductor Opto Division. It features a gallium arsenide infrared-emitting diode optically coupled to a triac output in a 6-lead plastic dual inline package (DIP). The device provides an insulation voltage of 5300 Vrms and supports a maximum repetitive peak off-state voltage of 400 V. It operates within a temperature range of -40 °C to 85 °C, with a nominal input trigger current of 15 mA and a maximum on-state current of 100 mA.
Feature Summary
- Non-zero crossing triac output configuration for phase control applications
- High isolation voltage capability of 5300 Vrms between input and output circuits
- Compliant with UL and VDE safety standards for industrial equipment
Applications
- Solid state relay driver circuits
- AC motor speed control systems
- Lighting dimmer controls
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches required packaging or tape-and-reel specifications if applicable. Check current manufacturing status as availability may vary. Ensure compliance with RoHS directives and relevant regional regulatory requirements before integration into final products.
Selection Notes
Select this component when non-zero crossing switching is required for AC load control. Verify that the 400 V blocking voltage meets circuit peak voltage requirements. Ensure the 100 mA on-state current capacity is sufficient for the connected load. Consider thermal management within the specified operating temperature range during design.
Part Context
The K3021P belongs to the K3020P series of phototriac output optocouplers. This family provides electrical isolation for triggering triacs and SCRs in AC power control applications. The device utilizes a gallium arsenide LED for efficient light emission coupled to a sensitive triac output structure.
Replacement Considerations
Cross-reference with MOC3020X for functional compatibility in similar non-zero crossing applications. Verify pinout alignment and electrical parameter equivalence before substitution.
