Product details
Overview
DMC2053UVTQ 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 bidirectional power control. It delivers 4.6A/–3.2A continuous drain current at +25°C, supports low-voltage logic-level drive down to 1.8V, and is AEC-Q101 qualified for automotive power management.
For engineers reviewing the DMC2053UVTQ datasheet, DMC2053UVTQ pinout, DMC2053UVTQ application, or DMC2053UVTQ equivalent, this dual-channel MOSFET enables compact, high-efficiency synchronous rectification, load switching, and DC-DC converter topologies where space-constrained bidirectional control and thermal robustness are critical.
Technical Context
This device integrates two discrete enhancement-mode MOSFETs-N-channel and P-channel-with matched gate thresholds (0.4–1.0V and –0.45 to –1.0V), enabling complementary operation without external level-shifting. Its low RDS(ON) at 2.5V gate drive (43mΩ/110mΩ) supports direct interfacing with 2.5V/3.3V microcontrollers.
The TSOT26 package provides thermally efficient junction-to-ambient resistance of 108°C/W (with 1-inch² copper pad), while its low input capacitance (369pF/440pF) and fast switching (tF = 3.6ns/18ns) minimize switching losses in high-frequency (>1MHz) DC-DC converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | ±20V - Supports rail-to-rail operation across 3.3V–12V input systems without breakdown risk. |
| RDS(ON) (N) | 35mΩ @ VGS = 4.5V - Enables <175mW conduction loss at 4.6A, critical for thermally constrained PCB layouts. |
| RDS(ON) (P) | 74mΩ @ VGS = –4.5V - Ensures symmetric on-resistance for balanced push-pull stage efficiency. |
| Qg (N/P) | 3.6nC / 5.9nC - Low total gate charge reduces driver power demand and enables 1MHz+ PWM operation. |
| ID (Cont) | 4.6A / –3.2A @ +25°C - Sustains peak load currents in portable backlight drivers and USB-C PD power paths. |
| TJ Range | –55°C to +150°C - Validated for under-hood automotive environments and industrial temperature cycling. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive power semiconductors including HTGB, HTRB, and ESD. |

| 2 (S1) | N-channel source | Reference node for N-MOS gate drive; tied to output or ground depending on topology. |
| 3 (G1) | N-channel gate | Logic-level input (1.8V–12V compatible); requires <3.6nC charge for full turn-on. |
| 4 (D2) | P-channel drain | Main current path for low-side P-MOSFET; connects to output node in synchronous buck stage. |
| 5 (S2) | P-channel source | Connected to input rail in low-side switch; forms common source with N-MOS for half-bridge use. |
| 6 (G2) | P-channel gate | Inverted logic interface; driven low to conduct, requiring dedicated gate driver or logic inversion. |
Key Features

Applications
| Backlight LED Driver | Synchronous Buck Converter |
|---|---|
|
Use Scenario: Driving white LED strings in automotive instrument clusters with PWM dimming up to 20kHz. IC Role / Device Role / Timing Role: N-MOS as high-side switch, P-MOS as synchronous rectifier in boost-fed constant-current stage. Use Value: 35mΩ/74mΩ RDS(ON) minimizes voltage drop across both switches, preserving headroom for 3–4 LED series stacks at 300mA. |
Use Scenario: 5V-to-3.3V point-of-load conversion in ADAS camera modules with strict thermal limits. IC Role / Device Role / Timing Role: Integrated N+P pair forms compact half-bridge; N-MOS high-side, P-MOS low-side with dead-time control. Use Value: Low Qg (3.6nC/5.9nC) enables clean 2MHz switching with <10ns propagation delay mismatch, reducing output ripple. |
| USB-C Power Delivery Switch | Automotive Body Control Module |
|
Use Scenario: Bidirectional 20V/3A power path switching between legacy USB-A and USB-C ports in docking stations. IC Role / Device Role / Timing Role: N-MOS handles forward direction (source→sink), P-MOS enables reverse current flow during DRP negotiation. Use Value: Matched ±20V BVDSS and symmetrical RDS(ON) ensure identical forward/reverse conduction loss (<75mW each direction). |
Use Scenario: Controlling 12V solenoid valves and LED indicators in door module ECUs with 150°C junction rating. IC Role / Device Role / Timing Role: P-MOS as high-side load switch, N-MOS as diagnostic shunt for current sensing via source resistor. Use Value: AEC-Q101 qualification and –55°C to +150°C operation guarantee reliability across cold cranking and engine bay thermal cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC2056UVTQ | Higher RDS(ON): 48mΩ/100mΩ @ 4.5V; same TSOT26 footprint and pinout. | Lower efficiency at high current; suitable only for <2A loads where cost reduction outweighs thermal penalty. | Select when BOM cost is prioritized over thermal margin and peak efficiency is not required. |
| SI6926ADQ-T1-GE3 | Higher VDSS: ±30V; larger SO-8 package; higher Qg (12nC/15nC). | Supports wider input range but occupies 3× PCB area; slower switching limits >500kHz use. | Choose only if system requires >20V absolute maximum rating and layout space permits SO-8. |
Compared with DMC2053UVTQ, DMC2056UVTQ trades 37% higher conduction loss for lower unit cost, while SI6926ADQ-T1-GE3 sacrifices compactness and switching speed for extended voltage headroom-making DMC2053UVTQ optimal for space- and efficiency-critical 20V automotive and portable power designs.

FAQ
What is the maximum safe operating junction temperature for DMC2053UVTQ?
The absolute maximum junction temperature is +150°C per the datasheet's Thermal Characteristics table. Operation at this limit requires derating continuous current to ≤2.6A (N-channel) and ≤–2.6A (P-channel) at +70°C ambient, using the 1-inch² copper pad layout specified in Note 6. Exceeding this temperature risks permanent parametric shift or bondwire failure.
Can DMC2053UVTQ be used in a high-side N-MOS + low-side N-MOS synchronous buck configuration?
No-DMC2053UVTQ integrates one N-channel and one P-channel MOSFET, not two N-channels. Its P-channel device is optimized for high-side switching with simplified gate drive (no bootstrap circuit needed), not low-side synchronous rectification. For dual-N configurations, consider discrete N-MOS pairs or dedicated synchronous buck controllers with external N-MOS drivers.
Is the TSOT26 package of DMC2053UVTQ compatible with standard reflow profiles for lead-free soldering?
Yes-the device uses matte tin annealed terminals and is rated for JEDEC J-STD-020 Level 1 moisture sensitivity, permitting exposure to ambient indefinitely before reflow. It complies with IPC/JEDEC J-STD-020D peak reflow temperatures up to 260°C for 30 seconds, matching standard lead-free SAC305 profiles without preconditioning.
Does the AEC-Q101 qualification cover both N-channel and P-channel devices in the same package?
Yes-the qualification report DS41617 Rev. 2 explicitly states that the entire DMC2053UVTQ assembly-including both integrated MOSFET dice, interconnects, and TSOT26 molding-is subjected to AEC-Q101 stress tests (HTGB, HTRB, TC, UHAST, etc.) as a single qualified part number. No separate qualification is required for either channel.
