MMDT5451-7-F

Overview

The MMDT5451-7-F is a complementary NPN/PNP small signal transistor pair manufactured by Diodes Incorporated in an SOT363 surface-mount package. The NPN section (5551) offers a collector-emitter voltage of 160 V and continuous current of 200 mA, while the PNP section (5401) provides -150 V and -200 mA. It features a DC current gain ranging from 80 to 250 for the NPN and 50 to 240 for the PNP at specified test conditions. The device operates within a temperature range of -55°C to +150°C and includes AEC-Q101 qualification for high reliability applications.

Feature Summary

• Complementary NPN and PNP transistors integrated into a single ultra-small SOT363 package
• Qualified to AEC-Q101 standards for automotive and high-reliability environments
• Epitaxial planar die construction with lead-free, halogen-free, and antimony-free compliance

Applications

• Medium power amplification circuits
• General purpose switching applications
• Automotive electronic systems requiring high reliability components

Procurement Notes

Verify the specific ordering suffix '-7-F' corresponds to the 3,000-unit reel size and KNM marking code as documented in the official datasheet. Confirm that the required compliance marks align with project specifications for RoHS and AEC-Q101 standards before finalizing procurement orders.

Selection Notes

Select this component when space constraints necessitate an SOT363 package for complementary transistor pairs. Ensure the design voltage requirements do not exceed 160 V for NPN or -150 V for PNP sections. Verify that the thermal resistance characteristics fit the PCB layout and ambient operating conditions.

Part Context

This part belongs to the MMDT5451 series of complementary small signal transistors. It integrates two distinct transistor types, a 5551 NPN and a 5401 PNP, into one compact footprint. The series is designed for applications requiring matched complementary pairs in minimal board space.

Replacement Considerations

Direct substitutes must match the SOT363 package, pinout configuration, and electrical ratings. Verify compatibility with the 5551/5401 internal transistor types. Cross-reference with other manufacturers offering AEC-Q101 qualified complementary pairs in identical form factors.
