TLP267J(TPR,E

Triac, SCR Output Optoisolators Overview

The TLP267J(TPR,E is a phototriac output optocoupler manufactured by Toshiba Semiconductor and Storage. It features a GaAs infrared LED coupled to a photo-triac detector within an SO-6-4 surface-mount package. The device provides 3750 Vrms isolation voltage and supports a peak off-state voltage of 600 V. Key electrical parameters include a maximum trigger LED current of 3 mA, a forward current of 6 mA, and an on-state RMS current of 70 mA. It operates without a zero-crossing circuit, with a maximum turn-on time of 100 µs. The unit weight is 80 mg, and it functions within a temperature range of -25°C to +85°C.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix (TPR) against official Toshiba documentation to confirm tape-and-reel packaging specifications. Ensure that the selected variant matches the required isolation voltage and thermal characteristics for the target application environment. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and active status before finalizing procurement orders.

Triac, SCR Output Optoisolators Selection Notes

Select this component when low trigger current requirements are necessary for driving AC loads via optical isolation. The absence of a zero-crossing circuit makes it suitable for phase-control applications where precise timing is required. Compare the 70 mA RMS current capability against load requirements to ensure adequate margin. Consider the SO-6-4 footprint constraints during PCB layout design to maintain proper creepage distances.

Triac, SCR Output Optoisolators Part Context

This device belongs to the TLP267J/TLP268J family of phototriac output photocouplers from Toshiba. While sharing similar core electrical characteristics such as 600 V blocking voltage and 3750 Vrms isolation, variants differ in packaging and internal circuitry. The TLP267J specifically lacks a zero-crossing detection circuit, distinguishing it from the TLP268J which includes one. This family is designed for general-purpose AC switching in industrial and consumer electronics.

Triac, SCR Output Optoisolators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with direct replacements by matching pinout configurations, isolation ratings, and trigger current specifications against the original Toshiba datasheet.
