SS32

Single Diodes Overview

The MDD SS32 is a surface mount Schottky barrier rectifier belonging to the SS3 series, housed in a DO-214AC (SMA) package. It features a maximum average forward rectified current of 3.0 A and a repetitive peak reverse voltage of 20 V. The device operates within a junction temperature range of -55°C to +125°C and supports high forward surge currents up to 80 A. Electrical characteristics include a typical instantaneous forward voltage of 0.55 V at 3.0 A and a maximum DC reverse current of 0.5 mA at rated blocking voltage.

Single Diodes Feature Summary

• Metal silicon junction with majority carrier conduction for low power loss and high efficiency
• Built-in strain relief designed for automated placement and surface mount applications
• High forward surge current capability suitable for demanding circuit conditions
• Compliant with RoHS III and REACH standards while remaining halogen-free

Single Diodes Applications

• Surface mount rectification in general electronic circuits
• DC-DC converter output rectification stages
• Free-wheeling diode applications in inductive load protection

Single Diodes Procurement Notes

Verify the specific part code SS32A00000S020 against the original manufacturer designation MDD Diodes/SS32 to ensure correct sourcing. Confirm that the requested units match the DO-214AC/SMA case style and the 20V repetitive peak reverse voltage rating. Ensure compliance requirements such as RoHS III and halogen-free status are explicitly stated in the purchase order documentation.

Single Diodes Selection Notes

Select this component when a 3.0 A continuous current rating and 20 V reverse voltage blocking capability are required in a compact SMA footprint. Consider the thermal resistance of 70 °C/W and the operating temperature limits when designing heat dissipation strategies. Evaluate the 0.55 V forward voltage drop for efficiency calculations in low-voltage power supply designs.

Single Diodes Part Context

This component is part of the SS3 series of surface mount Schottky barrier rectifiers manufactured by MDD Diodes. The series offers various voltage ratings from 20 V to 200 V within the same physical package family. The SS32 specifically denotes the 20 V variant, providing a standardized solution for low-voltage, high-current rectification needs in modern electronics manufacturing.

Single Diodes Replacement Considerations

Cross-reference parts include SS32 from Taiwan Semiconductor, Fairchild Semiconductor, General Semiconductor, and Micro Commercial Components. Verify pinout compatibility and electrical parameters before substitution.
