ACDBB3100-HF

Overview

The ACDBB3100-HF is a single Schottky barrier rectifier manufactured by Comchip Technology. It features a silicon epitaxial planar chip with metal-silicon junction technology, housed in an SMD/DO-214 package. The device supports a repetitive reverse voltage (Vrrm) of 100 V and a forward current (If) of 3 A. Key electrical parameters include a maximum forward voltage (Vf) of 850 mV, a peak forward surge current (Ifsm) of 80 A, and a reverse current (Ir) of 200 µA at 100 V. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Ultra-high-speed switching capability for efficient power conversion
• Low forward voltage drop to minimize power loss and enhance efficiency
• High surge current capability for robust circuit protection
• Lead-free construction compliant with environmental standards

Applications

• DC-DC converters
• Power supply units
• Free-wheeling diodes in inductive circuits
• Polarity protection circuits

Procurement Notes

Verify the specific datasheet revision and RoHS status before procurement, as manufacturing transitions may affect compliance documentation. Confirm package markings and lead availability through authorized distributors. Ensure storage conditions meet semiconductor handling guidelines to prevent moisture sensitivity issues prior to soldering.

Selection Notes

Select this component when a 3 A continuous current rating and 100 V blocking voltage are required in a compact surface-mount form factor. Consider the 850 mV forward voltage drop for thermal management calculations. Compare against standard rectifiers if ultra-fast switching or low reverse leakage is critical for the specific application efficiency targets.

Part Context

This part belongs to Comchip Technology's ACDBB series of Schottky barrier rectifiers. The series is designed for high-efficiency applications requiring fast recovery times and low power dissipation. The DO-214 package provides a balance between current handling capacity and board space optimization, suitable for modern automated surface-mount assembly processes.

Replacement Considerations

Consult official substitution lists for equivalent parts with matching 3 A, 100 V specifications and compatible DO-214 footprints. Verify that alternative components meet the same thermal resistance and surge current requirements to ensure system reliability without redesign.
