SLA5068

Overview

The SLA5068 is a N-channel power MOSFET manufactured by Sanken Electric USA Inc., designed for 5-phase motor drive applications. It features a drain-source voltage rating of 60V and a continuous drain current of 7A, with a pulsed current capability of 15A. The device exhibits an on-resistance of 0.1Ω at VGS=10V and ID=3.5A. Electrical characteristics include a gate-source breakdown voltage of ±20V and a threshold voltage ranging from 1.0V to 2.0V. Thermal performance specifies a junction-to-case resistance of 2.5°C/W and a maximum junction temperature of 150°C.

Procurement Notes

Verify the specific package variant required, as the SLA5068 series includes multiple SIP configurations such as SLA15Pin and SLA21Pin with fins. Confirm thermal requirements against the datasheet's junction-to-air resistance values when designing without external heatsinks. Ensure input signals align with the specified gate-source voltage limits to prevent damage.

Selection Notes

Select this component for applications requiring a 60V rated N-channel switch with 7A continuous current capacity. Evaluate thermal dissipation needs based on the provided safe operating area curves and junction-to-case resistance. Consider the specific SIP package dimensions and pinout configuration to ensure compatibility with the target PCB layout and mounting constraints.

Part Context

The SLA5068 belongs to Sanken's SLA series of discrete power MOSFETs tailored for motor drive functions. This series utilizes SIP packaging options like the SLA15Pin and SLA21Pin variants, which often incorporate thermal fins to improve heat dissipation. These components are engineered to replace older bipolar transistor solutions in modern motor control architectures.
