Overview
The MMBD4448HCQW-7 is a surface-mount fast switching diode array manufactured by Diodes Incorporated. It features four independent diodes in a common cathode configuration within an SOT353 package. The device supports a maximum working peak reverse voltage of 80 V and a continuous forward current of 500 mA. Key electrical characteristics include a maximum reverse recovery time of 4 ns, a total capacitance of 3.5 pF, and a power dissipation rating of 200 mW. Operating temperatures range from -55°C to +150°C.
Feature Summary
- Fast switching speed with low reverse recovery time
- Low forward voltage drop for efficient conduction
- Ultra-low reverse leakage current
- Small surface-mount footprint
Applications
- General-purpose switching applications
- High-speed signal processing circuits
- DC-DC converter output rectification
- Clamping and protection circuits
Procurement Notes
Verify the specific ordering suffix '-7-F' to confirm tape and reel packaging quantities. Ensure the component matches the required SOT353 package variant. Confirm RoHS compliance and halogen-free status if environmental regulations apply to your assembly process. Cross-reference datasheet revision DS30153 Rev. 20-2 for accurate specifications.
Selection Notes
Select this component when space constraints require a quad diode array in a compact SOT353 package. Consider its 4 ns reverse recovery time for high-frequency switching requirements. Evaluate thermal management needs based on the 200 mW power dissipation limit at ambient temperatures up to 150°C.
Part Context
This part belongs to the MMBD4448 series of surface-mount fast switching diode arrays. It shares similar electrical performance with variants like MMBD4448HAQW but differs in internal pinout configuration. The HCQW designation specifically identifies the quad common cathode arrangement housed in the SOT353 outline.
