BA779-HG3-08

Overview

The BA779-HG3-08 is an RF PIN diode manufactured by Vishay General Semiconductor - Diodes Division, housed in a SOT-23-3 surface-mount package. It features a single pair series connection configuration with a maximum reverse voltage of 30V and a forward current rating of 50 mA. Key electrical parameters include a capacitance of 0.5pF at 0V reverse bias measured at 100MHz, and a resistance of 50 Ohm at 1.5mA forward current also at 100MHz. The device is designed for high-frequency applications and operates within a junction temperature range up to 125°C.

Feature Summary

Single pair series connection topology for RF signal handling
Low capacitance characteristic suitable for high-frequency operation
Surface-mount SOT-23-3 packaging for compact integration

Applications

RF switching circuits
Attenuator designs
Phase shifter implementations

Procurement Notes

Verify the manufacturer part number BA779-HG3-08 against official Vishay documentation to ensure authenticity. Confirm that the SOT-23-3 package type matches the design requirements. Check RoHS3 compliance status if environmental regulations apply to the specific project. Ensure the supplier provides valid traceability documents for the component batch.

Selection Notes

Select this component when a low-capacitance RF PIN diode is required for series connection applications. The 0.5pF capacitance at 0V makes it suitable for high-frequency signals where minimal signal loss is critical. Consider the 50 Ohm resistance at 1.5mA for impedance matching needs. The 30V reverse voltage rating defines the maximum operating limits for the RF circuit design.

Part Context

This component belongs to the Vishay RF PIN diode family, specifically designed for radio frequency applications. It utilizes the standard SOT-23-3 footprint common in modern electronics manufacturing. The HG3 suffix indicates lead-free and halogen-free construction compliant with international environmental standards.
