Triac, SCR Output Optoisolators datasheet and documents for FOD4208T

FOD4208T

Triac, SCR Output Optoisolators Overview

The FOD4208T is a random phase triac output optocoupler manufactured by onsemi. It integrates an infrared emitting diode with a hybrid random phase triac formed by two inverse parallel SCRs, designed to drive discrete triacs without snubber circuits. Key electrical parameters include a maximum continuous output current of 300 mA and an off-state output voltage (VDRM) of 800 V. The device offers high isolation with a rated insulation voltage of 5000 Vrms. It operates within a temperature range of -55°C to +100°C and features a maximum trigger current of 2 mA. The component is housed in a PDIP-6 package.

Triac, SCR Output Optoisolators Feature Summary

Integrates an infrared LED coupled to a hybrid random phase triac for direct discrete triac driving

Triac, SCR Output Optoisolators Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm the specific suffix 'T' indicates tape and reel packaging if required for automated assembly. Check current lifecycle status as availability may vary. Ensure compliance with RoHS directives relevant to the manufacturing date code. Validate datasheet revisions against the specific batch production requirements.

Triac, SCR Output Optoisolators Selection Notes

Select this component when snubberless triac driving is required in AC power applications. The random phase triggering allows firing at any point in the AC cycle, unlike zero-crossing variants. Ensure the load current does not exceed the 300 mA continuous limit. Verify that the 800 V blocking voltage meets the peak line voltage requirements. Consider the PDIP-6 package constraints for thermal management and PCB layout.

Triac, SCR Output Optoisolators Part Context

The FOD4208T belongs to the FOD420 family, which includes related devices like the FOD420, FOD4216, and FOD4218. These components share similar internal structures combining an IR LED with hybrid triac outputs. The family is designed for general-purpose AC switching applications requiring galvanic isolation between control circuitry and high-voltage AC loads.
