UNISONIC TECHNOLOGIES CO., LTD UT3419 Power MOSFET 20V, 3.5A P-CHANNEL ENHANCEMENT MODE FIELD EFFECT TRANSISTOR DESCRIPTION The UTC UT3419 is a P-channel enhancement MOSFET providing designers with excellent RDS(ON), low gate charge. The gate voltage is as low as 2.5V. The UTC UT3419 can be applied in PWM applications or used as a load switch. FEATURES * RDS(ON) < 75mΩ (VGS = -10V) RDS(ON) < 95mΩ (VGS = -4.5V) RDS(ON) < 145mΩ (VGS = -2.5V) SYMBOL ORDERING INFORMATION Ordering Number Note: UT3419G-AE2-R UT3419G-AE3-R Pin Assignment: S: Source Package G: Gate SOT-23-3 SOT-23 D: Drain Pin Assignment 1 2 3 S G D S G D Packing Tape Reel Tape Reel MARKING 34VG www.unisonic.com.tw Copyright © 2014 Unisonic Technologies Co., Ltd 1 of 4 QW-R502-391.F UT3419 Power MOSFET ABSOLUTE MAXIMUM RATINGS (TA =25°C, unless otherwise specified) PARAMETER Drain to Source Voltage Gate to Source Voltage RATINGS UNIT -20 V ±12 V TA =25°C -3.5 A Continuous Drain Current (Note 1) ID TA =70°C -2.8 A Pulsed Drain Current (Note 2) IDM -15 A TA =25°C 1.4 W PD Total Power Dissipation (Note 1) TA =70°C 0.9 W Junction Temperature TJ -55 ~ +150 °C Storage Temperature TSTG -55 ~ +150 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. SYMBOL VDSS VGSS THERMAL DATA PARAMETER SYMBOL RATINGS UNIT t ≤ 10s 90 °C/W Junction to Ambient (Note 1) θJA Steady-State 125 °C/W 2 Notes: 1. The value of θJA is measured with the device mounted on 1in FR-4 board with 2oz. Copper, in a still air environment with TA =25°C. The value in any a given application depends on the user's specific board design. The current rating is based on the t ≤ 10s thermal resistance rating. 2. Repetitive rating, pulse width limited by junction temperature.
