• Power MOSFET technology enabling robust high-voltage operation
• Three-channel half-bridge output configuration

Applications

• Home appliances

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Current inventory levels are depleted, and no further stock will be replenished upon exhaustion. Procurement should focus on verifying the authenticity of remaining surplus units from authorized distributors or secondary market sources, ensuring compliance with RoHS standards and checking for physical integrity prior to integration into new designs.

Selection Notes

Engineers selecting this part must account for its discontinued status and limited availability. The device is suitable for applications requiring a 200V load capability and 2.5A output current in a compact SIP form factor. Designers should evaluate the thermal performance within the specified -20°C to 150°C junction temperature range and ensure the PCB layout accommodates the 24-ZIP through-hole package dimensions.

Part Context

The SMA6864MZ belongs to the SMA6860 series of motor drivers from Sanken Electric. This series is characterized by high-voltage integration and is primarily targeted at household appliance markets. The specific LF2451 suffix denotes the lead-free packaging variant compatible with standard assembly processes.

Replacement Considerations

The SMA6861MZ-LF2451 is documented as a parameter-equivalent substitute.
