Overview
The 189NQ135-1 is a Schottky rectifier module manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 135 V and an average forward current rating of 180 A. The device utilizes the PRM1-1 Half-Pak module package, designed for chassis mounting. It supports a junction temperature range up to 175°C. This component replaces three parallel DO-5 diodes, offering a lower profile and easier mounting characteristics.
Feature Summary
- Schottky barrier technology for high efficiency
- Half-Pak module construction for high power density
- Designed to replace multiple parallel discrete diodes
Applications
- High current DC power supplies
- Industrial motor drives
- Battery charging systems
Procurement Notes
Verify the specific suffix requirements with the manufacturer, as packaging or variant differences may exist. Confirm chassis mounting compatibility and thermal interface specifications before integration. Ensure the procurement channel provides original manufacturer documentation to validate authenticity and technical parameters.
Selection Notes
Select this component for applications requiring high current handling in a compact form factor. The 175°C junction temperature capability allows for robust operation in demanding thermal environments. Consider the PRM1-1 package dimensions for mechanical fit and ensure adequate heatsinking for the 180 A current rating.
Part Context
This part belongs to the single diode category within SMC Diode Solutions' portfolio. It is specifically engineered as a high-power replacement for traditional parallel diode configurations. The PRM1-1 package distinguishes it from standard axial or surface-mount diodes by providing a dedicated chassis-mount solution for heavy-duty electronics.
Replacement Considerations
The datasheet indicates this module replaces three parallel DO-5 diodes. Verify that the alternative solution matches the 135 V reverse voltage and 180 A current ratings. Ensure the replacement maintains the same PRM1-1 footprint and thermal performance characteristics.
