HS3G

Single Diodes Overview

The HS3G is an ultrafast recovery rectifier manufactured by Good-Ark Semiconductor, designed for high-efficiency surface-mount applications. It features a DO-214AB (SMC) package and supports a maximum average forward rectified current of 3.0 A. The device offers a maximum repetitive peak reverse voltage of 400 V and a maximum DC blocking voltage of 400 V. Key electrical characteristics include a typical junction capacitance of 50 pF, a maximum instantaneous forward voltage of 1.7 V at 3.0 A, and a typical reverse recovery time of 1 ns. The component operates within a junction temperature range of -55°C to +150°C.

Single Diodes Procurement Notes

Verify the specific part marking and datasheet revision against the manufacturer's official documentation before procurement. Ensure that the required reverse voltage and current ratings align with the circuit design specifications. Confirm compliance with RoHS directives if environmental regulations apply to the final assembly. Cross-reference the DO-214AB package dimensions with the PCB footprint layout to guarantee mechanical compatibility during surface mount assembly processes.

Single Diodes Selection Notes

Select the HS3G when a 400 V reverse voltage rating is required alongside a 3 A continuous forward current capability. This component is suitable for designs prioritizing fast switching speeds due to its 1 ns reverse recovery time. Consider the SMC package size for space-constrained boards requiring robust lead frame strain relief. Evaluate thermal management requirements based on the derating curve provided in the datasheet for ambient temperatures exceeding 25°C.

Single Diodes Part Context

The HS3G belongs to the HS3x series of ultrafast recovery rectifiers from Good-Ark Semiconductor, which includes variants ranging from HS3A to HS3M. These devices are engineered for general-purpose high-efficiency rectification in surface-mount configurations. The series shares common physical attributes such as the DO-214AB package and plastic construction, differing primarily in their voltage ratings. This family targets modern power electronics demanding compact form factors and improved switching performance.

Single Diodes Replacement Considerations

Direct substitutes must match the 400 V reverse voltage, 3 A forward current, and DO-214AB package. Verify that alternative components exhibit comparable reverse recovery times and forward voltage characteristics to maintain circuit efficiency.
