PT200S16 3-Phase Bridge Diode Module

Overview

The PT200S16 is a diode module. Public NIEC datasheet sources identify it as a 3-phase bridge diode module with an isolated base, high surge capability, and general-use rectification as its stated application.

Public technical references also place it in the 200 A class and the 1600 V class within the PT200 family.

This model is a rectifier device for power-conversion work. It is not an IGBT module and not a switching transistor assembly.

Its function is tied to bridge rectification, which is why exact device-type confirmation is essential before replacement.

Technical Data

Application Value

This module fits three-phase rectifier sections, converter input stages, industrial DC power assemblies, and general power-conversion equipment where a packaged bridge rectifier is required.

The published circuit description and typical-application note place it directly in rectification service.

Selection Notes

For selection, the critical points are the 3-phase bridge structure, the 200 A current class, the 1600 V class, and the fact that this is a diode module.

Those characteristics must match the original power-stage function.

FAQ

Q1: Is PT200S16 an IGBT module?
No. Public datasheet sources identify PT200S16 as a diode module, specifically a 3-phase bridge diode module. Its role is rectification, not transistor switching.

Q2: What kind of power circuit is it intended for?
It is intended for general-use rectification in a 3-phase bridge circuit.

The datasheet description places it directly in three-phase rectifier service rather than in gate-controlled switching applications.

Q3: Why does the isolated base matter?
The isolated base is one of the listed product features. It is important because it affects how the module is mounted in power assemblies and how insulation is handled at the mechanical interface.

Q4: Why is the 3-phase bridge structure so important when ordering a replacement?
Because the internal circuit defines the module’s job in the power stage.

If the original assembly uses a 3-phase bridge diode module, the replacement must preserve that same circuit function.

Q5: What should be checked before ordering?
Check the installed part number, confirm the original circuit uses a 3-phase bridge diode module, and verify the required current class and voltage class before replacement.
