MCZ33198EFR2

Overview

The MCZ33198EFR2 is an obsolete high-side TMOS gate driver manufactured by NXP USA Inc. Designed for automotive applications, it drives external power MOSFETs in xEV traction inverters, onboard chargers (OBC), and DC-DC converters. The device operates within a junction temperature range of -40°C to 150°C and features non-inverting input logic. It utilizes an 8-SOIC surface-mount package and complies with EU environmental standards including ROHS certification and the REACH directive.

Feature Summary

• Dedicated high-side driver architecture for external TMOS transistors
• Optimized for electric vehicle traction inverter and power conversion systems
• Automotive-grade thermal performance supporting high junction temperatures

Applications

• xEV traction inverters
• Onboard chargers (OBC)
• DC-DC converters

Procurement Notes

This component is officially classified as obsolete and no longer manufactured by NXP. Procurement must rely on secondary market distributors or surplus inventory. Verify authenticity carefully due to the discontinued status. Confirm that the specific lot date code meets project requirements before acquisition, as availability is limited and supply chain stability cannot be guaranteed through primary channels.

Selection Notes

Engineers requiring active alternatives should evaluate current NXP high-side gate drivers compatible with SiC and IGBT modules. Consider devices offering similar voltage ratings and SOIC packaging if pin compatibility is required. Review updated datasheets for improvements in switching speed or protection features available in newer generations of automotive gate driver ICs.

Part Context

Part of the MC33198 family of high-side TMOS drivers intended for robust automotive environments. The EFR2 suffix typically denotes specific tape-and-reel packaging and compliance certifications. This series supports high-current applications typical of modern electric vehicle powertrains and auxiliary power systems.

Replacement Considerations

No public confirmed substitute part numbers are documented for this obsolete component. Engineers must identify functional equivalents based on electrical specifications and pinout compatibility from current product portfolios.
