Single Diodes datasheet and documents for SK315SMA
Single Diodes Overview
The SK315SMA is a surface-mount Schottky barrier rectifier diode manufactured by Diotec Semiconductor. It features a single silicon junction in a DO-214AC (SMA) package. The device supports an average forward current of 3 A and a repetitive peak reverse voltage of 150 V. Key electrical parameters include a maximum forward voltage of 0.87 V at 3 A, a non-repetitive peak forward surge current of 80 A at 50 Hz, and a leakage current of less than 100 µA at 25°C. The component operates within a temperature range of -50°C to +150°C.

Single Diodes Procurement Notes
Verify the specific ordering suffix against official documentation to confirm compliance requirements. Confirm that the component grade matches standard commercial or industrial reliability standards. Ensure the selected part aligns with the required thermal resistance values for the intended PCB layout. Validate RoHS and REACH status through manufacturer datasheets before integration.
Single Diodes Selection Notes
Select this component based on its 150 V reverse voltage rating and 3 A continuous current capacity. Consider the 0.87 V maximum forward voltage drop for efficiency calculations. Evaluate the thermal performance using the specified junction-to-terminal thermal resistance. Ensure the operating environment stays within the -50°C to +150°C junction temperature limits.
Single Diodes Part Context
This device belongs to the SK32SMA through SK315SMA series of SMD Schottky Barrier Rectifiers. The series offers various voltage ratings while maintaining a consistent 3 A forward current capability. All variants share the same DO-214AC package and general mechanical characteristics defined by the manufacturer.
