Product details

Overview

DMC3071LVT from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in a single TSOT26 package, integrating an N-channel (30V, 50mΩ @ V_GS=10V, 4.6A) and P-channel (–30V, 95mΩ @ V_GS=–10V, –3.3A) device for bidirectional power control. It delivers low R_DS(ON), fast switching, and low gate charge to support high-efficiency DC-DC converters and backlighting circuits in space-constrained portable electronics.

For engineers reviewing the DMC3071LVT datasheet, DMC3071LVT pinout, DMC3071LVT application, or DMC3071LVT equivalent, key selection criteria include dual-channel voltage rating symmetry, gate threshold matching (±1.0–2.5V), thermal resistance (R_θJA = 117°C/W with copper pad), and TSOT26 footprint compatibility for synchronous buck-boost and H-bridge topologies.

Technical Context

This dual MOSFET implements complementary channel pairing in one monolithic TSOT26 package, enabling compact half-bridge and level-shifting configurations without inter-device timing skew. Its matched V_GS(TH) tolerances (N: 1.0–2.5V; P: –1.0 to –2.5V) and low C_iss (190pF / 254pF) support precise dead-time control and reduced shoot-through risk in 3.3V/5V logic-driven power stages.

The device uses a thermally enhanced FR-4 layout with 1-inch² copper plate (PD = 1.1W, R_θJA = 117°C/W) and features ultra-low Q_g (4.5nC N-ch / 6.5nC P-ch at rated V_GS) to minimize drive loss in high-frequency (>1MHz) DC-DC applications such as LED driver current sinks and USB-C PD power path switches.

Key Specifications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMC2038LVT-7	Lower V_DSS (±20V), higher R_DS(ON) (70mΩ/130mΩ), same TSOT26 package	Better suited for 3.3V/5V logic-only systems; not rated for 24V transients	Select when operating voltage stays below 16V and board space is identical.
SI6926ADQ-T1-GE3	Higher V_DSS (±30V), asymmetric R_DS(ON) (32mΩ/110mΩ), SO-8 package	Larger footprint but higher current rating (5.5A/–4.2A); better thermal performance (R_θJA = 62°C/W)	Choose for higher-power 24V industrial DC-DC where thermal headroom is critical.

Compared with DMC2038LVT-7, DMC3071LVT offers 30% higher voltage margin and lower on-resistance for 24V-compatible buck-boost designs; versus SI6926ADQ-T1-GE3, it trades 30% smaller footprint and lower cost for reduced thermal capacity-ideal for consumer portables where size outweighs peak power.

FAQ

What is the maximum safe operating junction temperature for DMC3071LVT?

The absolute maximum junction temperature is +150°C, verified per datasheet Section "Thermal Characteristics." Operation above this limit risks permanent degradation of gate oxide integrity and increased R_DS(ON). Derating is required above +125°C ambient when using the 117°C/W thermal resistance configuration.

Can DMC3071LVT be driven directly from a 3.3V microcontroller GPIO?

Yes-the N-channel V_GS(TH) (1.0–2.5V) and P-channel V_GS(TH) (–1.0 to –2.5V) allow full enhancement at 3.3V logic levels. However, the P-channel requires inverted drive: a 0V GPIO output turns it ON, while 3.3V turns it OFF-matching standard high-side P-FET control schemes.

Does DMC3071LVT include integrated ESD protection on its gate terminals?

No explicit ESD protection circuitry is specified in the datasheet. The device meets HBM Class 2 (≥2kV) per JEDEC JESD22-A114, but external 100Ω series gate resistors and 12V TVS diodes are recommended for robustness in automated assembly and field-replaceable modules.

How does the TSOT26 package affect thermal performance compared to SO-8 alternatives?

TSOT26's small footprint limits copper area for heat spreading, resulting in R_θJA = 117°C/W (vs. ~62°C/W for SO-8). To maintain T_J < 125°C at 1.1W, PCB layout must include ≥1″² 2oz copper pour under the exposed pad-verified in Diodes' AN-TC-001 thermal design note.
