ACDBT-54S-HF

Overview

The ACDBT-54S-HF is an automotive-grade Schottky barrier rectifier manufactured by Comchip Technology. It features a single pair series connection configuration housed in a surface-mount SOT-23-3 package. The device is rated for a maximum repetitive peak reverse voltage of 30 V and offers a forward current capability of 200 mA. Designed for high-efficiency applications, it utilizes silicon epitaxial planar chip technology with metal-silicon junctions to ensure low forward voltage drop and ultra-high-speed switching characteristics suitable for demanding electronic environments.

Feature Summary

• Automotive-grade reliability with halogen-free construction
• Ultra-high-speed switching performance for efficient power management
• Low forward voltage drop contributing to reduced power loss
• Guardring structure provides enhanced overvoltage protection

Applications

• Automotive electronics systems requiring robust diode protection
• High-frequency switching power supply circuits
• Low-voltage DC-DC converter topologies
• Reverse polarity protection in compact consumer devices

Procurement Notes

Verify the specific suffix 'HF' confirms halogen-free compliance as per manufacturer specifications. Confirm that the SOT-23-3 package dimensions align with your PCB footprint requirements. Ensure the 30V reverse voltage rating meets the peak inverse voltage demands of your target circuit application before finalizing component selection.

Selection Notes

Select this component when automotive qualification and small form factor are primary constraints. The SOT-23-3 package is ideal for space-constrained designs. Consider the 200mA current limit against your load requirements. This part is suitable for low-voltage applications where speed and efficiency outweigh high-current needs.

Part Context

This device belongs to Comchip's automotive Schottky diode portfolio, which emphasizes reliability in harsh environments. The product line focuses on halogen-free materials and gold termination options to prevent tin whiskers. It complements other small signal rectifiers in the ACDBT series, offering consistent performance across various voltage ratings within the same package family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with equivalent automotive-grade Schottky diodes from other manufacturers based on pinout and electrical ratings.
