MMBD4448HCQW-TP

Overview

The MMBD4448HCQW-TP is a small signal switching diode manufactured by Micro Commercial Components (MCC). It features an SOT-363 surface-mount package and contains a dual diode array configuration. The device supports a maximum average forward current of 250 mA and withstands a peak reverse voltage of 80 V. Key electrical characteristics include a fast recovery time of 4 ns, a forward voltage of 1.25 V at specified currents, and a low reverse leakage current of 100 nA. It operates within a temperature range from -65°C to +150°C junction temperature.

Feature Summary

• Fast switching capability with a 4 ns recovery time for high-speed signal processing
• Low forward voltage drop to minimize power loss in conduction states
• Compact SOT-363 surface-mount footprint for space-constrained designs
• Dual diode array configuration allowing multiple functions in a single package

Applications

• High-speed signal switching circuits
• Clamping and protection applications
• Logic level shifting interfaces
• General purpose rectification in compact electronics

Procurement Notes

Verify the specific suffix HCQW against the manufacturer's latest datasheet to confirm pinout and electrical tolerances. Ensure the ordering code matches the required tape and reel packaging format. Cross-reference the RoHS compliance status with current environmental regulations before finalizing procurement orders.

Selection Notes

Select this component when a dual diode array is required in an SOT-363 package. It is suitable for applications demanding fast switching speeds and low forward voltage. Compare the 250 mA current rating against circuit requirements to ensure adequate headroom. Consider the 80 V reverse voltage limit for appropriate biasing conditions.

Part Context

This part belongs to the MMBD4448 series of fast switching diodes from MCC. It shares similar electrical performance with other variants like the MMBD4448DW-TP but differs in package type and internal configuration. The series is designed for general-purpose switching tasks where size and speed are critical factors in the overall system design.

Replacement Considerations

Direct substitutes may include MMBD4448DW-TP or MMBD4448HTW-TP if package compatibility allows. Verify that the replacement maintains the same dual diode configuration and meets the 80 V and 250 mA specifications. Check for identical pin assignments to ensure board-level interchangeability without redesign.
