SMA5125

Overview

The SMA5125 is a dual MOSFET module integrating one N-channel and one P-channel power transistor within a single SMA package. The N-channel device supports a drain-source voltage of 60 V, continuous current of 10 A, and on-resistance of 0.14 Ω at 4 V gate drive. The P-channel counterpart provides -60 V breakdown, -10 A continuous current, and 0.14 Ω resistance at -10 V gate drive. Thermal performance includes a junction-to-case resistance of 4.166 °C/W and a maximum operating junction temperature of 150 °C.

Feature Summary

• Integrated complementary N-channel and P-channel MOSFETs in a compact surface-mount package
• Low on-resistance optimized for high-efficiency switching applications
• High thermal conductivity design with low junction-to-case resistance

Applications

• 3-phase motor drive circuits
• Synchronous rectification stages
• Half-bridge driver configurations

Procurement Notes

Verify the specific ordering suffix against official Sanken Electric documentation to confirm pin configuration and internal circuit topology. Ensure the component meets RoHS compliance requirements for your target market. Confirm that the SMA footprint aligns with your PCB layout standards before finalizing procurement.

Selection Notes

Select this component when space constraints require a matched pair of N-channel and P-channel devices. Verify that the 60 V rating exceeds the maximum circuit voltage including transients. Check that the gate drive voltage levels are compatible with the specified RDS(on) thresholds for both channels.

Part Context

This part belongs to the SMA series of dual MOSFET modules manufactured by Sanken Electric USA Inc. It is designed as a compact solution for replacing discrete pairs of transistors in power conversion topologies where symmetry and thermal matching between N-channel and P-channel devices are critical.

Replacement Considerations

Check for alternative SMA-series dual MOSFETs from Sanken Electric or other manufacturers offering similar 60 V ratings and package dimensions. Verify pinout compatibility and electrical parameter equivalence before substitution.
