Single Diodes Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm exact electrical tolerances and packaging configurations. Ensure the selected variant matches the required thermal and mechanical specifications for the target application environment. Cross-reference part numbers with authorized distributors to confirm availability and authenticity.

Single Diodes Selection Notes

Select this component for designs requiring compact surface-mount solutions with high reliability under stress conditions. The integrated guard ring makes it suitable for robust industrial or automotive environments where voltage spikes may occur. Evaluate the 100 V reverse voltage rating against circuit peak inverse voltages to ensure adequate safety margins during operation.

Single Diodes Part Context

This device belongs to the Nexperia BAT46WJ series of Schottky barrier diodes. It is designed as a general-purpose rectifier offering a balance of speed and low loss. The SOD-323F package allows for automated assembly in space-constrained printed circuit board layouts common in modern consumer and industrial electronics.

Single Diodes Replacement Considerations

Direct substitutes must match the SOD-323F footprint, 100 V reverse voltage, and 250 mA forward current ratings. Verify that alternative components maintain comparable forward voltage characteristics and reverse leakage currents to ensure circuit performance parity.
