FMMT718TC

Single Bipolar Transistors Overview

The FMMT718TC is a PNP silicon low saturation transistor manufactured by Diodes Incorporated in an SOT-23 package. It supports a continuous collector current of -1.5 A and a peak pulse current of -6 A, with a collector-emitter breakdown voltage exceeding -20 V. The device features a maximum power dissipation of 625 mW at +25°C and operates within a temperature range of -55°C to +150°C. Electrical characteristics include a transition frequency of 180 MHz and a static forward current transfer ratio (hFE) characterized up to -6 A.

Single Bipolar Transistors Feature Summary

• Low saturation voltage for efficient switching performance
• High current gain hold-up capability up to -6 A pulsed operation
• RoHS compliant and halogen-free green device construction

Single Bipolar Transistors Applications

• Gate driving MOSFETs and IGBTs
• DC-DC converters
• Charging circuits
• Power switches

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'TC' against official documentation to confirm the 10,000-unit reel size and standard marking code. Ensure compliance requirements match project specifications, as automotive-grade variants require separate datasheets and qualification processes distinct from this commercial component.

Single Bipolar Transistors Selection Notes

Select this component for applications requiring high-current switching with minimal voltage drop. Compare the -1.5 A continuous rating against load requirements and verify thermal management capabilities given the 625 mW dissipation limit. Consider the complementary NPN type FMMT618 if push-pull configurations are necessary for the circuit design.

Single Bipolar Transistors Part Context

This part belongs to the FMMT718 series of PNP silicon planar transistors designed for power switching applications. It utilizes a molded plastic case with matte tin-plated leads and meets UL flammability classification 94V-0 standards. The device is intended for surface mount assembly on FR4 PCBs with copper coverage.

Single Bipolar Transistors Replacement Considerations

The complementary NPN type FMMT618 serves as a functional pair for push-pull designs. Automotive-compliant alternatives are available under the FMMT718Q designation, which requires separate qualification verification.
