Single Diodes datasheet and documents for SK34B

SK34B

Single Diodes Overview

The Good-Ark Semiconductor SK34B is a surface mount Schottky rectifier in the DO-214AA (SMB) package. It features a maximum average forward rectified current of 3.0 A and a maximum repetitive peak reverse voltage of 40 V. The device supports an operating junction and storage temperature range from -55°C to +150°C. Electrical characteristics include a maximum instantaneous forward voltage of 0.55 V at 3 A and a typical junction capacitance of 4.0 pF at 4.0 V, 1 MHz.

Single Diodes Feature Summary

Low forward voltage drop for improved efficiency
High junction temperature capability up to 150°C
Moisture sensitivity level 1 per J-STD-020
Plastic package with UL flammability classification 94V-0

Single Diodes Applications

Low voltage high frequency inverters
Free wheeling applications
Polarity protection circuits

Single Diodes Procurement Notes

Verify the specific part number against official datasheets to confirm electrical ratings and package type. Ensure compliance with RoHS and halogen-free requirements if specified by adding the 'E' suffix. Confirm AEC-Q101 qualification status for automotive applications. Check moisture sensitivity level and storage conditions prior to assembly.

Single Diodes Selection Notes

Select the SK34B when a 40 V reverse voltage rating and 3 A continuous current are required in a compact SMB package. Consider its low forward voltage drop for efficiency in low voltage designs. Verify thermal resistance values for heat dissipation needs. Ensure the operating temperature range meets system requirements.

Single Diodes Part Context

The SK34B belongs to the SK32B thru SK36B series of surface mount Schottky rectifiers manufactured by Good-Ark Semiconductor. This series offers reverse voltages ranging from 20 V to 60 V with a consistent 3 A forward current rating. All devices share similar physical dimensions and mounting characteristics within the DO-214AA package.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers offering 40 V, 3 A Schottky rectifiers in DO-214AA packages. Verify pinout compatibility and thermal performance metrics before substitution.
