MPL-102S

Overview

The Sanken Electric USA Inc. MPL-102S is a silicon diode designed for pulse rectification applications. It features a resin molded structure with UL94V-0 flammability rating. Key electrical parameters include a transient peak reverse voltage of 200 V and an average forward current of 10 A. The device supports a peak surge forward current of 65 A for 10 msec. Forward voltage drop is limited to 0.98 V at 5.0 A. Reverse leakage current is 100 µA maximum at VRM, rising to 200 µA at Tj=150°C. Thermal resistance from junction to case is 2.5 °C/W. Operating temperatures range from -40°C to +150°C.

Procurement Notes

Verify the specific datasheet revision number against the manufacturer's official documentation before finalizing procurement. Confirm that the component marking aligns with the specified lot number format and polarity indicators. Ensure that the supplier provides traceability documentation consistent with the original Sanken Electric manufacturing standards. Cross-reference the absolute maximum ratings with the actual operating conditions of the target application to prevent overstress failures during transient events.

Selection Notes

Select this component when high surge current capability and fast recovery are required in a compact package. Evaluate the thermal management requirements based on the 2.5 °C/W junction-to-case resistance. Consider the derating curves for average forward current relative to lead temperature. Ensure the circuit design respects the 200 V peak reverse voltage limit under all operating transients.
