Overview
The K3021PG is a phototriac output optocoupler from Vishay Semiconductor Opto Division, featuring a gallium arsenide infrared-emitting diode optically coupled to a triac in a 6-lead plastic DIP package. It operates without a zero-crossing circuit and provides an insulation voltage of 5300 Vrms. Key electrical parameters include a maximum continuous output current of 100 mA, a blocking voltage (VDRM) of 400 V, and a forward current (If) rating of 80 mA. The device functions within a temperature range of -40°C to +85°C.
Feature Summary
- Non-zero crossing operation for immediate load control
- High isolation voltage capability for safety applications
- Integrated gallium arsenide infrared emitter
Applications
- Automatic control systems
- Light intensity meters
- Electronic counters
Procurement Notes
Verify component status as the K3021PG series may be obsolete or end-of-life. Confirm RoHS compliance details and specific packaging configurations with authorized distributors before procurement. Ensure replacement strategies are evaluated due to potential discontinuation risks associated with this part number.
Selection Notes
Select this component for applications requiring non-synchronized AC switching where precise timing relative to the voltage zero-crossing is not required. The high isolation voltage makes it suitable for safety-critical interfaces. Verify that the 400 V blocking voltage meets the peak line voltage requirements of the target circuit design.
Part Context
This component belongs to the K3020P(G) series, which includes variants like the K3020P and K3021P. These devices share similar structural designs but may differ in specific electrical ratings or certification approvals. The series is designed for general-purpose AC load control in industrial and consumer electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult official Vishay resources for current equivalent recommendations.
