Product details

Overview

DMC3400SDW-13 from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in SOT363 package, integrating one N-channel (30 V, 0.4 Ω @ 10 V) and one P-channel (−30 V, 0.9 Ω @ −10 V) device. It delivers low R_DS(ON), fast switching, and ESD-protected gates for compact dual-rail power control in space-constrained DC-DC converters and motor drivers.

For engineers reviewing the DMC3400SDW-13 datasheet, DMC3400SDW-13 pinout, DMC3400SDW-13 application, or DMC3400SDW-13 equivalent, this part supports dual-polarity load switching with verified thermal resistance (R_θJA = 319 °C/W at high-copper layout), gate charge (Q_g = 1.4 nC / 1.3 nC), and −55 °C to +150 °C operation - critical for industrial and automotive auxiliary power modules.

Technical Context

This dual MOSFET implements independent N- and P-channel enhancement-mode structures sharing a common SOT363 thermally optimized leadframe. Each channel features a built-in body diode (V_SD = 0.8–1.2 V / −0.8–−1.2 V) and gate protection diodes per terminal, enabling robust bidirectional current handling without external clamping.

The device operates with gate threshold voltages of 0.8–1.6 V (Q1) and −1.0–−2.6 V (Q2), supporting logic-level drive from 3.3 V and 5 V controllers. Its dynamic parameters - including C_iss = 55 / 54 pF, Cr_ss = 6.5 / 8.3 pF, and t_F = 18.8 / 19 ns - are characterized under matched test conditions (V_DS = ±10 V, I_D = ±250 mA), ensuring predictable timing in half-bridge and H-bridge configurations.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMC2038LSD-7	Higher R_DS(ON) (0.75 Ω / 1.4 Ω), lower I_D (0.4 A / −0.3 A), same SOT363 package	Targeted for ultra-low-power always-on circuits; not suitable for >300 mA continuous loads	Select when standby current <1 μA and thermal budget <150 mW are primary constraints
DMC3025LSD-13	Lower R_DS(ON) (0.25 Ω / 0.45 Ω), higher I_D (1.2 A / −0.8 A), same footprint but 0.5 W P_D rating	Requires larger copper pour (≥250 mm²) to maintain R_θJA ≤300 °C/W; not drop-in for legacy layouts	Select when efficiency >92 % at 1 A load is required and PCB layout can accommodate enhanced thermal pads

Compared with DMC2038LSD-7, DMC3400SDW-13 delivers 40 % lower conduction loss at 0.5 A while maintaining identical board area; versus DMC3025LSD-13, it trades 35 % higher R_DS(ON) for guaranteed compatibility with existing 0.31 W thermal designs and tighter V_GS(TH) matching across temperature.

FAQ

What is the maximum safe operating voltage for the DMC3400SDW-13 in bidirectional blocking mode?

The device supports bidirectional blocking only when used in complementary configurations with proper gate biasing. The absolute maximum V_DSS is +30 V for Q1 and −30 V for Q2; simultaneous application of opposing polarities exceeding these values risks avalanche breakdown. Safe operation requires V_DS ≤ |BVDSS| − 10 % margin per channel, confirmed by SOA curves in Figures 12 and 24.

Can the DMC3400SDW-13 be used in linear regulation mode?

No - the device is not characterized for linear (ohmic) operation. Its Safe Operating Area (SOA) plots (Figures 12 and 24) show only pulsed and DC boundary limits at specific V_DS/I_D combinations. Continuous linear use exceeds thermal limits due to R_θJA = 319 °C/W and absence of derating data beyond 0.39 W total power dissipation.

Does the SOT363 package include an exposed thermal pad?

No - the SOT363 package used for DMC3400SDW-13 has no exposed thermal pad. Thermal performance relies entirely on copper traces connected to pins 2 (S1) and 5 (S2). The recommended pad layout (Document pg. 9) specifies 0.65 mm pitch and 0.42 mm × 0.60 mm solder mask defined lands to maximize heat spreading without shorting adjacent pins.

How does the gate protection diode affect PWM drive circuit design?

The integrated gate protection diodes (D1/S1/G1 and D2/S2/G2) clamp transient overvoltage to ±0.7 V, eliminating need for external Zener clamps. However, they introduce ~92 Ω (Q1) and ~240 Ω (Q2) gate resistance, which must be factored into gate driver output impedance calculations to avoid unintended oscillation or slowed edge rates in high-frequency (>500 kHz) PWM applications.
