Overview
The MMBD4448HTW-7-F is a surface-mount fast switching diode array manufactured by Diodes Incorporated. It features four independent diodes in a single package with a maximum working peak reverse voltage of 80V and a forward continuous current rating of 500mA. The device provides a low forward voltage of up to 0.72V at 5mA and a fast reverse recovery time of 4ns. Total capacitance is limited to 3.5pF, and power dissipation reaches 200mW. It operates within a temperature range of -55°C to +150°C and is housed in an SOT-363 package.
Feature Summary
- Fast switching speed with a maximum reverse recovery time of 4ns
- Low forward voltage drop for efficient signal handling
- Ultra-low reverse leakage current under specified conditions
- Compact surface-mount design suitable for general-purpose applications
Applications
- General-purpose switching circuits
- High-speed digital logic interfaces
- Signal demodulation and rectification
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and packing quantity. Confirm RoHS compliance status and environmental declarations directly from the datasheet before procurement. Ensure the component meets all automotive or industrial qualification requirements if applicable to the target system.
Selection Notes
Select this component when a compact quad-diode configuration is required for high-speed signal processing. Evaluate the thermal resistance and power dissipation limits relative to the expected ambient operating temperature. Consider the low capacitance specification for high-frequency applications where signal integrity is critical.
Part Context
This part belongs to the MMBD4448 series of surface-mount fast switching diode arrays. It shares core electrical characteristics with variants such as the MMBD4448HCQW and MMBD4448HAQW, differing primarily in the physical package style and manufacturing site markings. The HTW suffix specifically denotes the SOT-363 package configuration.
Replacement Considerations
Cross-reference with other MMBD4448 series parts like MMBD4448HADW-7-F or MMBD4448HAQW-7-F for pin-compatible alternatives. Verify that any substitute maintains the same SOT-363 footprint and identical electrical ratings for reverse voltage and forward current.
