Overview
The Broadcom Limited 5082-2811#T25 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 dissipates up to 250 mW. 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 features a typical capacitance of 1.2 pF and package inductance of 2.0 nH.
Feature Summary
- Patented guard ring design ensures high breakdown voltage
- Pico-second switching speed for ultrafast performance
- Low turn-on voltage characteristics
- Hermetically sealed glass package
Applications
- High level detecting
- Mixing and switching applications
- Gating and log or A-D converting
- Video detecting and frequency discriminating
- Sampling and wave shaping
Procurement Notes
Verify the specific ordering suffix #T25 corresponds to the 2500-unit tape and reel container format as defined in the official datasheet. Confirm that the component meets all RoHS compliance requirements relevant to the intended deployment region before finalizing procurement orders.
Selection Notes
Select this component when a low turn-on voltage and pico-second switching speed are required for general purpose applications. Ensure the circuit design accommodates the 15 V minimum breakdown voltage and 250 mW power dissipation limits under the expected operating thermal conditions.
Part Context
This part belongs to the 5082-2800 series of Schottky barrier diodes manufactured by Broadcom Limited. It shares the Outline 15 glass package with other variants like the 5082-2800 and 5082-2810, offering matched characteristics for batch applications.
Replacement Considerations
The 1N5711 is an equivalent JEDEC registered number within the same family. Verify pinout compatibility and ensure the replacement meets the specific 15 V breakdown voltage requirement if substituting higher voltage variants.
FAQ
What is the effective carrier lifetime for the 5082-2811?
The effective carrier lifetime is 100 ps maximum, measured using the Krakauer method at 5 mA.
How does the capacitance vary with reverse voltage?
The capacitance decreases as the reverse voltage increases, dropping from approximately 1.2 pF at 0 V to lower values at higher voltages.
What is the recommended lead bending restriction?
The leads should be restricted so that the bend starts at least 1/16 inch from the glass body to prevent damage.
