TLP126(MBS-TPL,F)

Overview

The TLP126(MBS-TPL,F) is a mini flat coupler manufactured by Toshiba Semiconductor and Storage, designed for surface mount assembly. It integrates a photo transistor optically coupled to an infrared emitting diode connected in inverse parallel, enabling AC or DC input operation. Key electrical specifications include a collector-emitter voltage of 80V minimum, a current transfer ratio of 100% minimum at 1mA forward current, and an isolation voltage of 3750Vrms. The device operates within a temperature range of -55°C to 100°C and utilizes a 6-MFSOP package with four leads.

Feature Summary

Supports both AC and DC input signals through inverse-parallel LED configuration
Provides high current transfer ratio at low input currents
Offers robust electrical isolation between input and output circuits

Applications

Programmable Controllers
AC/DC Input Modules
Telecommunication Equipment

Procurement Notes

Verify the specific suffix MBS-TPL,F against official Toshiba documentation to confirm pinout and functional equivalence to standard TLP126 variants. Confirm RoHS compliance status and check for end-of-life notices, as distribution data indicates potential discontinuation for related TLP126 packages. Ensure the supplier provides valid traceability documents matching the manufacturer's part identification.

Selection Notes

Select this component when designing compact PCB layouts requiring surface mount isolation for logic-level signal transmission. The inverse-parallel LED structure makes it suitable for direct AC line sensing without additional rectification components. Consider the 80V collector-emitter voltage rating for low-voltage digital interface applications where galvanic isolation is required between control and load circuits.

Part Context

This device belongs to Toshiba’s mini flat coupler series, which focuses on reducing footprint while maintaining performance standards for industrial and communication interfaces. The TLP126 family is widely recognized for its reliability in programmable logic controller input stages, offering a balance of speed, isolation strength, and power efficiency in small outline packages.
