MMBD4448HTM-7

Overview

The MMBD4448HTM-7 is a small signal switching diode manufactured by Diodes Incorporated. It features a triple independent configuration housed in an SOT-26 surface-mount package. The device supports a peak reverse voltage of 80 V and an average forward current of 250 mA per diode. Key electrical parameters include a maximum reverse leakage current of 100 nA at 70 V, a forward voltage of 1.25 V at 150 mA, and a rapid reverse recovery time of 4 ns. It operates within a junction temperature range of -65°C to +150°C.

Feature Summary

• Triple independent diode array for compact circuit integration
• Ultra-fast switching speed with 4 ns reverse recovery time
• High conductance characteristics for efficient signal handling
• Robust thermal performance suitable for high-temperature environments

Applications

• General purpose high-speed switching circuits
• Signal demodulation and detection applications
• Clamping and protection stages in electronic systems

Procurement Notes

Verify the specific suffix HTM-7 against official Diodes Incorporated documentation to confirm the SOT-26 package and triple configuration. Ensure compatibility with RoHS standards if required by the target assembly process. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a compact triple-diode solution with fast switching capabilities is required. The SOT-26 package offers space efficiency compared to discrete single diodes. Consider the 80 V reverse voltage rating and 250 mA current capacity to ensure adequate headroom for the specific application signals and loads.

Part Context

This component belongs to the MMBD4448 series of surface mount switching diodes from Diodes Incorporated. The series is designed for general-purpose applications requiring fast response times. The HTM variant specifically denotes the triple configuration in the SOT-26 package, distinguishing it from dual or single diode variants within the same family.

Replacement Considerations

Check for direct substitutes such as MMBD4448HTC-7 or MMBD4448Q-7-F, noting that some variants may be discontinued. Verify pinout compatibility and electrical parameter equivalence, particularly reverse recovery time and forward voltage, when considering alternative manufacturers or packages.
