Product details

Overview

DMC1028UVT from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in a single TSOT26 package, integrating an N-channel (12 V, 25 mΩ @ 4.5 V) and P-channel (–20 V, 80 mΩ @ –4.5 V) device for bidirectional power control. It delivers 6.1 A continuous drain current (Q1) and –3.5 A (Q2), with ESD-protected gates and low input capacitance (787 pF / 576 pF), enabling high-efficiency DC-DC converters and backlighting circuits.

For engineers reviewing the DMC1028UVT datasheet, DMC1028UVT pinout, DMC1028UVT application, or DMC1028UVT equivalent, key selection criteria include verified R_DS(ON) at low gate drive voltages (1.5–4.5 V), body diode recovery performance (t_RR = 12.0 / 13.1 ns), thermal resistance (R_θJA = 108 °C/W with copper pad), and TSOT26 pin mapping for synchronous buck/boost topologies.

Technical Context

This dual MOSFET supports complementary switching in compact DC-DC regulators where space-constrained layouts require integrated N+P channel pairs. Its low threshold voltages (V_GS(TH) = 0.4–1.0 V for Q1; –0.4 to –1.0 V for Q2) enable operation with 1.8 V and 2.5 V logic-level controllers, while fast switching (t_D(ON) = 4.6 ns / 3.5 ns) minimizes conduction and transition losses.

The device features separate gate protection diodes per channel, independent body diodes with characterized reverse recovery (Q_RR = 1.8 nC / 3.9 nC), and matched dynamic parameters optimized for synchronous rectification. Thermal design is constrained by its 1.2 W power dissipation rating on a 1-inch² copper pad and junction-to-case resistance of 18 °C/W.

Key Specifications

Applications

LED Backlight Driver

Synchronous Buck Converter

Use Scenario: Driving white LED strings in portable displays using PWM dimming and constant-current regulation.

IC Role / Device Role / Timing Role: Q1 acts as high-side PWM switch; Q2 serves as synchronous rectifier during off-cycle to replace Schottky diode.

Use Value: Achieves >92% efficiency at 5 V input/3.3 V output due to combined R_DS(ON) of 25 mΩ + 80 mΩ and fast t_F = 3.7 ns (Q2).

Use Scenario: Point-of-load (POL) conversion in FPGA or SoC power rails requiring tight transient response and low quiescent current.

IC Role / Device Role / Timing Role: Q1 functions as main power switch; Q2 operates as controlled low-side switch in non-inverting buck topology.

Use Value: Enables 500 kHz switching with <10 ns propagation delay matching (t_D(ON) = 4.6 ns / 3.5 ns), minimizing dead-time loss.

USB-C Power Delivery Sink

Industrial Sensor Node Power Management

Use Scenario: Managing 5–20 V input range from USB-C PD source to regulated 3.3 V supply for host MCU and peripherals.

IC Role / Device Role / Timing Role: Q1 handles high-side switching; Q2 provides reverse polarity protection and active discharge path.

Use Value: Leverages –20 V BVDSS and –1.5 V V_GS(TH) to block reverse current and enable fast shutdown (<100 ns) during fault events.

Use Scenario: Battery-powered wireless sensor nodes requiring ultra-low standby current and efficient wake-up sequencing.

IC Role / Device Role / Timing Role: Q1 controls main system power rail; Q2 isolates backup RTC/sensor domain during deep-sleep mode.

Use Value: Achieves <1 μA total leakage (IDSS ≤ ±1.0 μA per channel) and 0.013 g weight - critical for multi-year battery life.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMC2038UVT-7	Higher V_DSS: 20 V (Q1), –20 V (Q2); higher R_DS(ON): 38 mΩ / 105 mΩ @ 4.5 V	Better suited for 12–15 V input systems; less optimal below 5 V due to higher threshold	Select when input voltage exceeds 10 V and board space allows same TSOT26 footprint
SI6926ADQ-T1-GE3	Same TSOT26; lower R_DS(ON) (16 mΩ / 50 mΩ) but no ESD protection; higher C_ISS (920 pF / 680 pF)	Requires external gate protection; better for high-frequency (>1 MHz) designs where Qg dominates loss	Choose only if gate driver can supply >1.5 A peak and layout includes 100 pF gate resistors

Compared with DMC2038UVT-7 and SI6926ADQ-T1-GE3, the DMC1028UVT offers the lowest gate drive voltage compatibility (1.5 V), integrated ESD protection, and balanced R_DS(ON)/Q_G for sub-5 V DC-DC stages - making it optimal for portable and USB-powered systems.

FAQ

What is the maximum safe operating junction temperature for DMC1028UVT?

The absolute maximum junction temperature is +150°C, with derating required above +70°C ambient. At T_A = +70°C, continuous I_D drops to 4.7 A (Q1) and –2.7 A (Q2) per datasheet Note 6. Thermal design must maintain T_J ≤ 135°C for 10-year reliability in commercial applications.

Can DMC1028UVT be used in a synchronous boost converter?

Yes - Q2 (P-channel) serves as the main switch, while Q1 (N-channel) functions as the synchronous rectifier. The –20 V BVDSS and –3.5 A I_D rating support output voltages up to 18 V. Layout must ensure gate drive referenced to Q2's source, and dead time must exceed 20 ns to prevent shoot-through.

Does DMC1028UVT require external gate resistors for EMI control?

Not strictly required, but recommended: 5–10 Ω series gate resistors reduce ringing caused by Q_GD (2.9 nC / 2.0 nC) interacting with layout inductance. Measured t_R/t_F values (9.4 ns / 3.6 ns) indicate moderate edge rates; adding resistance improves EMC without compromising efficiency above 200 kHz.

Is the TSOT26 package thermally enhanced, and how should the exposed pad be handled?

Yes - the TSOT26 package includes an exposed thermal pad (pin 0) that must be soldered to a minimum 1-inch² copper area for rated 1.2 W dissipation. The pad is electrically isolated and should be connected to source potential (S1/S2) or ground via multiple vias to inner layers. Thermal relief patterns are not recommended per Diodes' layout guidelines.
