NRVBB20H100CTT4G

Overview

The NRVBB20H100CTT4G is a switch-mode power rectifier manufactured by onsemi, featuring a dual anode common cathode configuration in a D2PAK-3 package. It supports a peak repetitive reverse voltage of 100 V and provides an average rectified forward current of 10 A per diode leg (20 A total). The device operates at junction temperatures up to +175°C with a maximum thermal resistance of 2.0°C/W from junction to case. Electrical characteristics include a maximum instantaneous forward voltage of 0.88 V at 20 A and 25°C, and a nonrepetitive peak surge current capability of 250 A.

Feature Summary

• Low forward voltage design for high efficiency and reduced power loss
• High surge capacity with controlled avalanche energy rating
• Guard-ring structure for enhanced stress protection
• AEC-Q101 qualified and PPAP capable for automotive applications

Applications

• Power supply output rectification
• Power management circuits
• Instrumentation systems

Procurement Notes

Verify the specific ordering suffix T4G to confirm the D2PAK-3 tape and reel packaging format. Confirm that the NRVBB prefix aligns with project requirements for unique site and control change specifications mandated by automotive standards. Ensure compliance with RoHS directives and lead-free material declarations before finalizing procurement orders.

Selection Notes

Select this component when designing switch-mode power supplies requiring low forward voltage drop to minimize conduction losses. The 175°C operating junction temperature allows for robust performance in thermally constrained environments. Verify that the 100 V blocking voltage meets the circuit's peak reverse voltage requirements under all operating conditions.

Part Context

This device belongs to the MBR20H100CT family of Schottky barrier rectifiers. It shares electrical specifications with variants such as MBRB20H100CTG but utilizes the NRVBB prefix to denote qualification for automotive applications requiring specific quality control changes and site verification protocols.
