MMBF170-7-F

Single FETs, MOSFETs Overview

The MMBF170-7-F is an N-channel enhancement mode MOSFET manufactured by Diodes Incorporated. It features a drain-source voltage (VDS) of 60 V and a continuous drain current (ID) of 200 mA at +25°C. The device offers a maximum on-resistance (RDS(ON)) of 5.0 Ω at VGS = 10V and ID = 200mA, or 5.3 Ω at VGS = 4.5V and ID = 50mA. Gate-source voltage limits are ±20 V continuous and ±40 V pulsed. Total power dissipation is 300 mW with a thermal resistance of 417 °C/W. Operating temperature ranges from -55°C to +150°C.

• Power-management functions

Single FETs, MOSFETs Procurement Notes

Verify the specific ordering suffix '-7-F' corresponds to the standard SOT23 package in a 3,000-unit tape and reel carrier. Confirm that the component meets the required environmental specifications, including RoHS 3 compliance and halogen-free status, as defined by the manufacturer's quality definitions. Ensure the selected part matches the exact datasheet revision for accurate electrical parameters.

Single FETs, MOSFETs Selection Notes

Select this component when a compact N-channel MOSFET with 60V capability is required for low-current applications up to 200mA. Consider the RDS(ON) performance at both 10V and 4.5V gate drive levels to ensure compatibility with the control logic. Evaluate the thermal constraints given the 300mW power dissipation limit in the SOT23 package for the intended ambient temperature conditions.

Single FETs, MOSFETs Part Context

This part belongs to the MMBF170 series of single N-channel MOSFETs designed for surface-mount assembly. It utilizes a standard SOT23 package molded in plastic with UL flammability classification 94V-0. The device is distinct from the automotive-compliant MMBF170Q variant, which is documented under a separate datasheet.

Single FETs, MOSFETs Replacement Considerations

The MMBF170Q-7-F is an automotive-compliant alternative within the same family. Verify if AEC-Q101 qualification is necessary for the application, as the standard MMBF170-7-F is qualified to JEDEC standards.
