TLP267J(T2-TPL,E

Triac, SCR Output Optoisolators Overview

The TLP267J(T2-TPL,E is a phototriac output optocoupler manufactured by Toshiba Semiconductor and Storage. It features a GaAs infrared LED coupled to a photo-triac in an SO-6-4 surface-mount package. Key electrical parameters include a maximum trigger LED current of 3 mA, a peak off-state voltage (VDRM) of 600 V, and an isolation voltage of 3750 Vrms. The device operates within a temperature range of -25°C to +85°C, with a forward voltage of 1.27 V at a forward current of 6 mA. It lacks a zero-crossing circuit and has a maximum turn-on time of 100 µs.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix configuration against the manufacturer's datasheet to ensure compatibility with required packaging and environmental standards. Confirm that the selected variant matches the intended thermal and electrical specifications for the target application environment. Cross-reference ordering codes with official distributor catalogs to avoid substitution errors during procurement.

Triac, SCR Output Optoisolators Selection Notes

Select this component when low trigger current is required for efficient LED driving in optocoupler interfaces. Ensure the application voltage does not exceed the 600 V peak off-state rating. Consider the absence of a zero-crossing circuit if precise phase-angle control is needed without inherent delay. Verify that the SO-6-4 package dimensions fit the PCB layout constraints.

Triac, SCR Output Optoisolators Part Context

This part belongs to the TLP267J series of phototriac output photocouplers from Toshiba. It is distinct from variants like the TLP268J, which includes a zero-crossing circuit. The series is designed for general-purpose AC switching applications requiring electrical isolation between control and power stages. It complements other Toshiba optocouplers offering different trigger currents or package styles.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes may include TLP267J(E or TLP267J(V4,E depending on packaging requirements. Verify pinout compatibility and electrical ratings before substitution. Alternative models from other manufacturers require careful comparison of VDRM, isolation voltage, and trigger current specifications.
