FSL34

Single Diodes Overview

The FSL34 is a surface mount Schottky barrier rectifier manufactured by Good-Ark Semiconductor, designed for high-efficiency power conversion. It features a maximum average forward rectified current of 3.0 A and a maximum repetitive peak reverse voltage of 40 V. The device operates within a junction temperature range of -55°C to +125°C and supports peak forward surge currents up to 30 A. Electrical characteristics include a typical instantaneous forward voltage of 0.46 V and a maximum reverse current of 1.0 mA at rated DC blocking voltage. The component utilizes an eSGA (SOD-123FL) package with a typical thermal resistance from junction to mount of 25 °C/W.

Single Diodes Procurement Notes

Verify the specific part number suffix against official Good-Ark Semiconductor documentation to ensure correct voltage rating and packaging configuration. Confirm compliance requirements such as RoHS and halogen-free status prior to integration. Cross-reference datasheet revision dates to validate electrical parameters and mechanical dimensions. Ensure storage conditions adhere to moisture sensitivity level 1 guidelines to maintain device integrity during assembly processes.

Single Diodes Selection Notes

Select the FSL34 when a 40 V reverse voltage rating is required alongside a 3 A continuous forward current capacity. The low forward voltage characteristic makes it suitable for applications prioritizing minimal conduction losses. Consider the eSGA package footprint for space-constrained PCB layouts. Evaluate thermal management needs based on the specified junction-to-mount thermal resistance value under defined copper pad conditions.

Single Diodes Part Context

The FSL34 belongs to the FSL32 through FSL34 series of surface mount Schottky rectifiers produced by Good-Ark Semiconductor. This family shares identical physical packages and forward current ratings, differing primarily in their maximum repetitive peak reverse voltage specifications. The series targets modern electronic designs requiring compact, efficient rectification solutions with reliable performance under varying thermal conditions.
