Overview
The ACDST-2004S-HF is a small signal switching diode array manufactured by Comchip Technology, designed for surface-mount applications. It features a single pair series connection configuration housed in an SOT-23 package. The device supports a maximum repetitive reverse voltage of 300V and a DC reverse voltage of 240V. It handles a continuous forward current of 225mA with a power dissipation rating of 350mW. The component operates within a junction temperature range of -65°C to +150°C and complies with AEC-Q101 automotive standards.
Feature Summary
- Automotive-grade reliability certified under AEC-Q101 standards
- Integrated dual-diode structure in compact SOT-23 packaging
- High thermal stability supporting extended operating temperatures
Applications
- Automotive electronic circuit protection
- General-purpose signal switching
- Clamping circuits in consumer electronics
Procurement Notes
Verify the specific suffix 'HF' indicates lead-free compliance against the manufacturer's latest documentation. Confirm the package designation matches SOT-23 or SC-59 specifications required by your PCB layout. Ensure the AEC-Q101 qualification status meets your project's automotive grade requirements before finalizing procurement.
Selection Notes
Select this component when a compact dual-diode solution is needed for low-current switching tasks. The 300V reverse voltage rating provides sufficient margin for standard low-voltage logic interfaces. Consider the 225mA forward current limit when designing load paths to ensure operation within safe thermal boundaries.
Part Context
This part belongs to Comchip Technology's line of discrete semiconductor products, specifically focusing on small signal switching diodes. The manufacturer specializes in surface-mount devices optimized for high-speed processes. This series integrates multiple diode functions into single packages to reduce board space.
Replacement Considerations
Cross-reference with other SOT-23 dual diode arrays from different manufacturers if supply constraints exist. Verify that substitute parts match the 300V reverse voltage and 225mA forward current ratings exactly.
