Product details

Overview

DMC2053UVT from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in a single TSOT26 package, integrating an N-channel (20V, 35mΩ @ 4.5V) and P-channel (–20V, 74mΩ @ –4.5V) device for synchronous switching. It delivers 4.6A/–3.2A continuous drain current at +25°C, supports low-voltage gate drive down to 1.8V, and targets high-efficiency DC-DC converters requiring compact dual-FET solutions.

For engineers reviewing the DMC2053UVT datasheet, DMC2053UVT pinout, DMC2053UVT application, or DMC2053UVT equivalent, key selection criteria include R_DS(ON) matching between channels, thermal resistance (R_θJA = 108°C/W with copper pad), gate charge asymmetry (Q_g = 3.6nC / 5.9nC), and TSOT26 footprint compatibility in space-constrained power stages.

Technical Context

This dual MOSFET implements independent N- and P-channel silicon die in one thermally optimized TSOT26 leadframe. The N-channel exhibits V_GS(TH) = 0.4–1.0V and fast switching (t_r = 3.0ns), while the P-channel features V_GS(TH) = –0.45 to –1.0V and higher gate charge (Q_gd = 2.1nC) for controlled turn-off in half-bridge configurations.

Both devices share identical thermal characteristics (T_J = –55°C to +150°C) and operate under ±12V gate ratings. Their matched R_DS(ON) temperature coefficients enable stable current sharing across temperature, and low C_iss (369pF/440pF) minimizes drive loss in high-frequency (>1MHz) buck regulators.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	20V (N), –20V (P): Supports input rails up to 18V in step-down converters with 20% margin.
R_DS(ON)	35mΩ @ 4.5V (N), 74mΩ @ –4.5V (P): Enables <1W conduction loss at 4A in compact 2.9×2.8mm layout.
I_D (cont)	4.6A (N), –3.2A (P) @ +25°C: Sustains peak load currents in portable backlight drivers without derating.
Q_g	3.6nC (N), 5.9nC (P): Allows efficient 1–2MHz PWM control using low-current gate drivers (e.g., TC4427).
R_θJA	108°C/W (with 1-inch² copper): Limits junction rise to ~117°C at 1.1W dissipation-within safe SOA limits.
C_iss	369pF (N), 440pF (P): Reduces Miller-induced shoot-through risk in synchronous rectification topologies.

Pinout & Package

TSOT26 package: 2.90 × 2.80 × 0.95 mm body height, matte tin-plated copper leadframe, JEDEC-compliant moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
1 (D1)	N-channel drain	Main current path for high-side N-FET; connects to input rail in buck high-side switch.
2 (S1)	N-channel source	Reference node for N-FET gate drive; ties to switch node in synchronous buck.
3 (G1)	N-channel gate	Control input for N-FET; requires ≥1.8V logic for partial turn-on, ≥4.5V for full R_DS(ON).
4 (D2)	P-channel drain	Shared drain with N-FET (internally connected); forms common switch node output.
5 (S2)	P-channel source	Connects to ground or output capacitor in buck low-side configuration.
6 (G2)	P-channel gate	Inverted control input; driven low to turn on P-FET; compatible with bootstrap or charge-pump gate drivers.

Key Features

Feature	Design Value
Complementary channel pairing	Matched V_GS(TH) polarity and R_DS(ON) scaling enables single-gate-driver synchronous buck operation.
Low R_DS(ON) at 2.5V	N-FET: 43mΩ, P-FET: 110mΩ-supports 2.5V I/O microcontrollers without level-shifting.
Low Q_gd/Q_g ratio	N: 1.0/3.6 = 0.28, P: 2.1/5.9 = 0.36-reduces Miller plateau duration and improves switching controllability.
Green compound packaging	Halogen- and antimony-free molding (Br+Cl <1500ppm, Sb <1000ppm) meets IPC-1752A environmental compliance.
Thermal performance	R_θJC = 37°C/W enables direct thermal coupling to PCB copper, critical for sustained 1W operation.

Applications

LED Backlight Driver

Synchronous Buck Converter

Use Scenario: Driving white LED strings in tablet displays using 3.3V/5V input with PWM dimming.

IC Role / Device Role / Timing Role: N-FET as high-side switch, P-FET as low-side synchronous rectifier in boost-derived current source topology.

Use Value: 35mΩ/74mΩ R_DS(ON) reduces conduction loss by >35% vs. discrete Schottky diode solution, extending battery life.

Use Scenario: Point-of-load regulation for FPGA core voltage (1.0–1.2V @ 3A) in industrial controllers.

IC Role / Device Role / Timing Role: Dual-FET power stage operating at 1.2MHz with external controller (e.g., TPS54332).

Use Value: Matched thermal response ensures balanced current sharing across temperature, preventing hot-spotting during transient loads.

USB-C Power Delivery Sink

Portable Audio Amplifier Supply

Use Scenario: Input protection and VBUS switching in USB-C PD receivers supporting 20V/3A profiles.

IC Role / Device Role / Timing Role: N-FET blocks reverse current from VBUS; P-FET controls discharge path during disconnect events.

Use Value: Low IDSS (<1µA) prevents leakage-induced battery drain during standby; ±12V V_GSS withstands ESD transients per IEC 61000-4-2.

Use Scenario: Class-D amplifier rail switching in Bluetooth speakers with dynamic headroom management.

IC Role / Device Role / Timing Role: P-FET as high-side switch, N-FET as active discharge path for rapid rail collapse during mute transitions.

Use Value: Fast t_f = 3.6ns (N) and t_d(off) = 31ns (P) enable sub-10µs rail ramp-down, eliminating pop/click artifacts.

Equivalent & Alternatives

The following parts are listed as comparable options for similar complementary MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMC2056UVT-7	Higher R_DS(ON): 50mΩ/105mΩ @ 4.5V/–4.5V; same TSOT26 footprint and pinout.	Lower efficiency in high-current (>3A) DC-DC stages due to +43% conduction loss.	Select when cost sensitivity outweighs 0.3W thermal penalty at full load.
SI6926ADQ-T1-GE3	Different package (SO-8), higher Q_g (12nC total), no integrated complementary pair-requires two separate dies.	Requires larger PCB area and dual gate drive routing; unsuitable for ultra-compact designs.	Choose only if legacy SO-8 layout reuse or higher voltage rating (30V) is mandatory.

Compared with DMC2053UVT, DMC2056UVT trades efficiency for cost in identical footprints, while SI6926ADQ demands more board space and drive complexity-making DMC2053UVT optimal for miniaturized, thermally constrained synchronous buck and LED driver designs.

FAQ

What is the maximum safe operating frequency for DMC2053UVT in a synchronous buck converter?

Based on measured t_r/t_f (3.0ns/3.6ns) and Q_g values, DMC2053UVT supports stable operation up to 2MHz with appropriate gate drive strength (≥2A peak) and PCB layout minimizing loop inductance. Above 2MHz, switching losses increase significantly due to Crss-dependent delay asymmetry between N- and P-channels.

Can DMC2053UVT be used in linear regulator configurations?

No-its R_DS(ON) is optimized for switching, not linear operation. At 4.6A, power dissipation would exceed 1.1W even at minimal V_DS, exceeding the 0.7W steady-state rating on standard FR-4. Thermal runaway risk is high due to positive R_DS(ON) temperature coefficient above 100°C.

Is the TSOT26 package lead-free and RoHS compliant?

Yes-DMC2053UVT uses matte tin annealed over copper leadframe and halogen-free green molding compound. It meets EU RoHS 2015/863/EU (RoHS 3), contains <900ppm bromine/chlorine and <1000ppm antimony, and is rated UL 94V-0 for flammability.

How does the internal connection between D1 and D2 affect PCB layout?

Pins 1 (D1) and 4 (D2) are internally shorted, forming a common drain node. This mandates connecting both pins to the same net-typically the switch node in buck topologies. Splitting them causes parasitic inductance that degrades EMI and increases voltage overshoot during turn-off.
