SS12HM2G

Single Diodes Overview

The SS12HM2G is a Schottky barrier rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a single silicon element housed in an SMA (DO-214AC) plastic package with two leads. The device is rated for a maximum average forward rectified current of 1 ampere and a repetitive peak reverse voltage of 20 volts. It is designed for lead-free operation and complies with RoHS standards, supporting operating temperatures up to 150 degrees Celsius.

Single Diodes Feature Summary

• Utilizes Schottky barrier technology for low forward voltage drop and minimal power loss
• Encapsulated in a compact, lead-free SMA surface-mount package
• Engineered for high thermal stability and reliable performance under elevated temperatures

Single Diodes Applications

• High-frequency rectification in DC-to-DC converter circuits
• Power supply input protection stages
• Free-wheeling diodes in inductive load switching applications

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact packaging quantities and tape-and-reel specifications. Ensure that the component meets the required environmental compliance standards for the target market. Cross-reference the date code and lot number with the supplier's certificate of conformity to guarantee authenticity and traceability before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a low-profile surface-mount solution is required for high-efficiency rectification at moderate current levels. The 20-volt rating suits low-voltage power systems where minimizing conduction losses is critical. Consider the thermal derating curves provided in the datasheet to ensure adequate heat dissipation within the SMA package constraints during continuous operation.

Single Diodes Part Context

This part belongs to the SSxxHM series of Schottky rectifiers from Taiwan Semiconductor. The series is characterized by its use of metal-semiconductor junction technology to achieve superior switching speeds compared to standard p-n junction diodes. The SMA package provides a balance between current handling capability and board space efficiency for consumer and industrial electronics.

Single Diodes Replacement Considerations

Direct replacements must match the 1A current rating, 20V reverse voltage, and SMA footprint. Verify that substitute Schottky diodes maintain comparable forward voltage characteristics and reverse leakage currents to ensure circuit performance parity without modifying the existing PCB layout.
