5082-2811

Overview

The Broadcom Limited 5082-2811 is a passivated Schottky barrier diode utilizing a patented guard ring design for high breakdown voltage. It operates within a junction temperature range of -65°C to +200°C and supports a DC power dissipation of 250 mW at 25°C case temperature. Key electrical specifications include a minimum breakdown voltage of 15 V, a maximum forward voltage of 410 mV at 15 mA, and a maximum reverse leakage current of 100 nA at 8 V. The device exhibits a typical package capacitance of 1.2 pF and package inductance of 2.0 nH.

Feature Summary

• Patented guard ring design ensures high breakdown voltage capability
• Pico-second switching speed suitable for high-frequency applications
• Low turn-on voltage characteristics optimized for signal detection

Applications

• High level detecting
• Mixing and switching circuits
• Gating and log or A-D converting
• Video detecting and frequency discriminating
• Sampling and wave shaping

Procurement Notes

Verify the specific ordering suffix (#T25, #T50) against the required container quantity (2500 or 5000 devices). Confirm RoHS compliance status as standard versions may not be compliant. Ensure the supplier provides the official Avago/Broadcom datasheet AV02-0429EN for final parameter validation before integration.

Selection Notes

Select the 5082-2811 when a minimum breakdown voltage of 15 V is required alongside low forward voltage. Compare with the 5082-2810 if a higher 20 V breakdown is needed, or the 5082-2835 for lower turn-on voltage needs. Consider matched pairs (5082-2826) if tight VF and CO matching is critical for the circuit design.

Part Context

This component belongs to the 1N5711/1N5712/5082-2800 series of general-purpose Schottky barrier diodes. It shares the Outline 15 glass package and similar thermal characteristics with other members like the 5082-2800 and 5082-2810, differing primarily in its specific breakdown voltage and leakage current ratings.

Replacement Considerations

The 1N5712 is a direct functional equivalent within the same series offering similar performance profiles. For surface mount requirements, the 1N5711UB or 1N5712UB ceramic packages provide military-grade qualifications.
