BA983-GS08

RF Diode Overview

The BA983-GS08 is a silicon planar band switching diode manufactured by Vishay Semiconductors in the QuadroMELF SOD-80 package. It features a reverse voltage rating of 35 V and a forward continuous current capacity of 100 mA. The component exhibits a maximum dynamic forward resistance of 1.2 Ω at 200 MHz with 3 mA forward current, and a typical diode capacitance of 1.2 pF at 100 MHz under 3 V reverse bias. Electrical characteristics include a forward voltage of 1000 mV at 100 mA and a reverse current of 50 nA at 20 V.

RF Diode Feature Summary

• Silicon planar construction providing low dynamic forward resistance and high reverse impedance
• QuadroMELF glass case packaging designed for surface mount applications
• Qualified to AEC-Q101 automotive standards for reliability
• Compliant with RoHS directive 2011/65/EU and WEEE directive 2002/96/EC

RF Diode Applications

• Band switching in VHF-tuners

RF Diode Procurement Notes

Verify the ordering code suffix against official documentation to confirm packaging options. The GS08 designation indicates tape and reel packaging containing 2,500 units per 7-inch reel. Confirm compliance requirements such as RoHS and AEC-Q101 status directly from the manufacturer datasheet before procurement.

RF Diode Selection Notes

Select the BA983-GS08 when a higher dynamic forward resistance compared to the BA982 variant is acceptable or required for specific circuit tuning. Ensure the operating environment remains within the specified junction temperature range of -55 °C to +150 °C and verify that the 100 mA forward current limit is not exceeded during operation.

RF Diode Part Context

The BA983-GS08 belongs to the BA98x series of band switching diodes produced by Vishay Semiconductors. This series utilizes silicon planar technology housed in the QuadroMELF SOD-80 glass case. The BA983 variant is specifically differentiated from the BA982 by its higher maximum dynamic forward resistance value while maintaining similar voltage ratings and package dimensions.

RF Diode Replacement Considerations

The BA982-GS08 serves as a direct alternative within the same family, distinguished only by a lower maximum dynamic forward resistance specification.
