SMA5135

Overview

The SMA5135 is a three-phase motor drive inverter manufactured by Sanken Electric. It integrates three half-bridge circuits, each configured with a P-channel and an N-channel MOSFET. The device supports a drain-to-source voltage of ±60 V and a continuous drain current of ±6 A. Key electrical parameters include a maximum static drain-to-source on-state resistance (RDS(ON)) of 0.22 Ω for both channel types. The component is housed in a SIP12 (SMA-12) package.

Feature Summary

• Integrates three half-bridge circuits composed of P-channel and N-channel MOSFETs
• Includes ESD protection Zener diodes at each gate terminal
• Compliant with RoHS directive

Applications

• Three-phase DC Motor Driver

Procurement Notes

Verify the specific datasheet revision (e.g., DSE Rev.1.1) to ensure alignment with design requirements. Confirm that the application environment remains within general-purpose electronic equipment limits, as high-reliability sectors like aerospace or medical devices require direct consultation with Sanken sales representatives before implementation.

Selection Notes

Select this component for applications requiring integrated three-phase control with low on-resistance. Ensure the operating temperature stays within the specified junction temperature range of 150 °C. Verify that the thermal management strategy accounts for the junction-to-ambient thermal resistance of 31.25 °C/W under all-element operation conditions.

Part Context

This part belongs to Sanken Electric's portfolio of power semiconductors designed for motor driving and power conversion. It serves as a discrete solution for controlling three-phase motors, offering a compact alternative to using individual MOSFETs. The SIP12 packaging facilitates integration into space-constrained designs compared to larger multi-chip modules.
