K3020P

Overview

The K3020P is a non-zero crossing phototriac output optocoupler manufactured by Vishay Semiconductor Opto Division. It integrates a gallium arsenide infrared-emitting diode with a phototriac in a 6-lead plastic dual inline package (DIP-6). Key electrical parameters include a maximum blocking voltage of 400 V, an isolation voltage of 5300 Vrms, and a continuous output current of 100 mA. The device operates within a temperature range of -40 °C to +85 °C.

Feature Summary

• Non-zero crossing triac output configuration for phase control applications
• High insulation voltage capability of 5300 Vrms
• Integrated gallium arsenide infrared emitter

Applications

• Solid-state relays
• Motor control circuits
• Lighting dimmers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as the K3020P may be obsolete. Ensure packaging matches DIP-6 specifications and validate datasheet revisions before integration into designs.

Selection Notes

Select this component for AC load switching where non-zero crossing operation is required. Consider the 400 V off-state voltage limit and 100 mA current rating against circuit demands. Evaluate thermal management requirements given the operating temperature range and power dissipation characteristics specified in the official documentation.

Part Context

This part belongs to the K3020P(G) series of optocouplers featuring phototriac outputs. It is designed for general-purpose AC switching applications requiring electrical isolation between control and load circuits. The series utilizes standard DIP-6 packaging for through-hole mounting.
