NFAM5065L4BT

Power Driver Modules Overview

The onsemi NFAM5065L4BT is a three-phase Intelligent Power Module (IPM) designed for high-performance motor control applications. It integrates N-channel IGBTs with gate drivers and protection circuits in a single package. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 650 V and a continuous collector current (Ic) of 50 A at 25°C. The module features a maximum power dissipation (Pd) of 192 W and a collector-emitter saturation voltage (VceSAT) of 2.05 V. It operates within a temperature range of -40°C to +150°C and utilizes a 30-pin SPM49 through-hole package.

Power Driver Modules Procurement Notes

Verify the specific suffix 'BT' against the manufacturer's latest datasheet to confirm pinout compatibility and internal component revisions. Ensure that the ordering documentation explicitly references the NFAM5065L4BT part number to avoid confusion with similar variants like NFAM5065L4B or NFAM5065L4BTL. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Power Driver Modules Selection Notes

Select this module when designing three-phase motor control systems requiring integrated protection and high reliability. The 650 V rating suits standard industrial voltage levels, while the 50 A current capacity supports moderate to high-power loads. Consider the SPM49 package dimensions for mechanical fit and thermal management strategies. Evaluate the need for external snubber circuits based on specific switching frequency and noise immunity requirements.

Power Driver Modules Part Context

This component belongs to the NFAM series of Intelligent Power Modules from onsemi. These modules are engineered to simplify the design of motor drive inverters by combining power switches and driver logic. The series targets applications demanding robust performance in harsh environments, offering reduced board space and improved electromagnetic interference characteristics compared to discrete solutions.

Power Driver Modules Replacement Considerations

NFAM5065L4B: Verify if the non-T suffix variant meets identical electrical and mechanical specifications. NFAM5065L4BTL: Check for differences in packaging or revision level. NFAM3065L4BT: Note the lower 30 A current rating; suitable only if load requirements permit downsizing.
