TLP628M(GB-TP1,E

Transistor, Photovoltaic Output Optoisolators Overview

The TLP628M(GB-TP1,E is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features a DC input driving an NPN phototransistor output, housed in a compact SOP-4 surface-mount package with a 7.5mm creepage distance. Key electrical parameters include a maximum isolation voltage of 5000Vrms, a collector-emitter saturation voltage of 400mV (max), and a forward voltage of 1.25V (typ). The device supports a continuous forward current of 50mA and an output current of 50mA, with a typical switching time of 10µs for both turn-on and turn-off.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix GB-TP1,E against official Toshiba documentation to confirm compliance with RoHS directives and lead-free manufacturing standards. Confirm that the SOP-4 package dimensions match your PCB layout constraints. Ensure the procurement channel provides valid traceability documents for quality assurance purposes.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a small form factor is required alongside standard transistor output characteristics. Compare the 5000Vrms isolation rating against system safety requirements. Evaluate the 10µs switching speed against the application's data rate needs. Consider the SOP-4 package availability relative to through-hole alternatives like DIP-4 if manual assembly is preferred.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the TLP628 series of transistor output optocouplers from Toshiba. The series offers various packaging options including DIP and SOP formats. The TLP628M variant specifically denotes the surface-mount configuration. This family is widely used in general-purpose isolation applications where cost-effectiveness and reliability are prioritized over high-speed performance.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements must maintain the SOP-4 package, 5000Vrms isolation, and similar CTR ranges. Verify pinout compatibility before substitution. Cross-reference with other Toshiba SOP-4 optocouplers or competitors offering identical electrical specifications and mechanical dimensions.
