MMBF4391LT1

Overview

The MMBF4391LT1 is an N-channel JFET switching transistor manufactured by onsemi. It operates with a Drain-Source Voltage (VDS) of 30 Vdc and a Gate-Source Breakdown Voltage (V(BR)GSS) of 30 Vdc. The Zero-Gate-Voltage Drain Current (IDSS) ranges from 50 mA to 150 mA at VDS = 15 Vdc. The device features a maximum total device dissipation of 225 mW on an FR-5 board at 25°C ambient temperature, with a junction-to-ambient thermal resistance of 556 °C/W. It supports a junction and storage temperature range from -55°C to +150°C.

Feature Summary

N-channel Junction Field Effect Transistor designed for switching applications
Pb-Free, Halogen Free/BFR Free, and RoHS Compliant construction
S Prefix variant available for automotive and unique site control change requirements

Applications

General purpose electronic switching circuits
Automotive applications requiring specific site and control change requirements
Low voltage signal routing and analog switching

Procurement Notes

Verify the exact ordering suffix when purchasing. The 'G' suffix indicates a Pb-Free package. Confirm if the 'S' prefix is required for automotive qualification or specific manufacturing site controls. Ensure the requested part number matches the specific electrical characteristics defined in the datasheet, as variations exist within the MMBF4391L family.

Selection Notes

Select this component based on the required IDSS range of 50 mA to 150 mA. Consider the 30 Vdc voltage ratings for drain-source and gate-source limits. Evaluate the thermal constraints, specifically the 225 mW dissipation limit, against the expected operating conditions. Verify packaging preferences between tape & reel and cut tape options.

Part Context

This device belongs to the MMBF4391L, MMBF4392L, and MMBF4393L series of N-channel JFET switching transistors. These components are housed in SOT-23 packages (CASE 318). The series offers different IDSS ranges to accommodate various switching impedance requirements while maintaining consistent voltage ratings and package dimensions.
