5082-3077

Overview

The Broadcom Limited 5082-3077 is a general-purpose silicon PIN diode designed for low-power RF switching and attenuating applications. It features a maximum breakdown voltage of 200 V, a total capacitance of 0.3 pF at 50 V reverse bias, and a residual series resistance of 1.5 Ω at 100 mA forward current. The device operates within a junction temperature range of -65°C to +150°C with a power dissipation rating of 250 mW at 25°C. It utilizes the Outline 15 glass hermetic package with dumet leads.

Feature Summary

• Low harmonic distortion and large dynamic range suitable for precision RF control
• Low series resistance and low capacitance characteristics for efficient signal handling
• Glass hermetic seal construction ensuring environmental stability

Applications

• RF duplexers
• Antenna switching matrices
• Digital phase shifters
• Time multiplex filters
• Variable RF attenuators
• Automatic gain control circuits
• RF limiters

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as standard packaging may contain lead. Check for specific ordering suffixes such as #T25 or #T50 to determine tape and reel quantities versus bulk packaging options before finalizing procurement orders.

Selection Notes

Select this component for general-purpose switching where a 200 V breakdown voltage and 0.3 pF capacitance are required. Ensure the application stays within the 250 mW power dissipation limit and operates between -65°C and +150°C. Consider the 1.5 Ω series resistance for attenuation calculations in control circuits.

Part Context

This part belongs to the 5082-3xxx series of general-purpose PIN diodes intended for RF switching and attenuating functions. It shares the same Outline 15 mechanical package and electrical testing conditions as related parts like the 5082-3001 and 5082-3039, differing primarily in specific breakdown voltage and resistance parameters.

Replacement Considerations

Direct functional equivalents include the 1N5719, which shares identical electrical specifications including 200 V breakdown voltage and 0.3 pF capacitance. Other members of the 5082-3xxx family may be considered if their specific breakdown voltages align with circuit requirements.

FAQ

What is the typical reverse recovery time for the 5082-3077?

The typical reverse recovery time is 100 ns when tested at a forward current of 20 mA and a reverse voltage of 10 V.

How is the 5082-3077 marked on the package?

The marking consists of digital coding where 'xxx' represents the last three digits of the part number (077) followed by the year digit and work week code.

What is the recommended minimum distance for lead bending?

Lead bending should start at least 1/16 inch (1.6 mm) from the glass body to prevent damage to the hermetic seal.
