Diode Arrays Procurement Notes

Verify the specific suffix (S or R) required for your design, as polarity marking differs between variants. Confirm compliance with RoHS standards if applicable to your region. Check for updated lifecycle status, as this component may be subject to obsolescence notices. Ensure lead torque does not exceed 0.59 N·m during assembly to prevent mechanical damage. Validate thermal management requirements against the specified junction temperature limits.

Diode Arrays Selection Notes

Select the FMM-26S when commercial frequency rectification is required with high surge tolerance. Ensure the operating junction temperature remains within the -40°C to +150°C range. Verify that the peak reverse voltage does not exceed 600V in steady-state conditions. Consider the 10A average forward current limit based on the specified lead temperature of 98°C. Evaluate the package dimensions for compatibility with the intended PCB layout.
