N-CHANNEL JFET

Product catalog summary

Description: The document details the specifications for the CENTRAL SEMICONDUCTOR CMPF4391 series, which are N-Channel Silicon Field Effect Transistors (JFETs) designed for switching applications. These transistors are manufactured using the epitaxial planar process and are encapsulated in a surface mount SOT-23 package.

Maximum Ratings: The maximum ratings at a temperature of 25°C include a Drain-Gate Voltage (VGD) of 40V, Gate-Source Voltage (VGS) of 40V, Drain-Source Voltage (VDS) of 40V, Gate Current (IG) of 50mA, and Power Dissipation (PD) of 350mW. The operating and storage junction temperature range is from -65°C to +150°C, with a thermal resistance (ΘJA) of 357°C/W.

Electrical Characteristics: The document provides detailed electrical characteristics for three models: CMPF4391, CMPF4392, and CMPF4393. Key parameters include:

Gate-Source Leakage Current (IGSS) at VGS=20V is 0.1nA, increasing to 0.2µA at 100°C.
Drain-Source Saturation Current (IDSS) varies across models, with CMPF4391 ranging from 50 to 150mA, CMPF4392 from 25 to 75mA, and CMPF4393 from 5.0 to 30mA.
Off-State Drain Current (ID(OFF)) is specified under various conditions, with maximum values of 0.1nA or 0.2µA at elevated temperatures.
Gate-Source Breakdown Voltage (BVGSS) is consistently 40V across all models.
Gate-Source Cutoff Voltage (VGS(OFF)) ranges from 4.0 to 10V for CMPF4391, 2.0 to 5.0V for CMPF4392, and 0.5 to 3.0V for CMPF4393.
On-State Drain-Source Voltage (VDS(ON)) and On-State Resistance (rDS(ON)) are also specified, with resistance values ranging from 30 to 100Ω.
Input Capacitance (Ciss) is 14pF, and Reverse Transfer Capacitance (Crss) varies with gate-source voltage.
Switching times (tON and tOFF) are provided, with tON ranging up to 15ns and tOFF up to 50ns depending on conditions.

Mechanical Outline: The SOT-23 package is described with lead codes: 1 for Drain, 2 for Source, and 3 for Gate. Marking codes for identification are 6J for CMPF4391, 6K for CMPF4392, and 6G for CMPF4393.
