Product details
Overview
DMC3061SVTQ-13 from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in TSOT26 package, integrating one 30V/3.4A N-channel and one −30V/−2.7A P-channel device. It delivers 60mΩ RDS(ON) @ VGS = 10V (Q1) and 95mΩ @ VGS = −10V (Q2), with low gate charge (6.6nC/6.8nC) and fast switching (tF = 51ns/21.8ns), enabling high-efficiency synchronous buck converters and dual-rail power management.
For engineers reviewing the DMC3061SVTQ datasheet, DMC3061SVTQ pinout, DMC3061SVTQ application, or DMC3061SVTQ equivalent, this AEC-Q101 qualified dual MOSFET supports automotive-grade DC-DC regulation, backlight LED drivers, and compact load-switch designs where space-constrained complementary switching and thermal reliability are critical.
Technical Context
This dual MOSFET implements independent N- and P-channel enhancement-mode structures sharing a common TSOT26 thermally optimized leadframe. Q1 operates with VGS(TH) = 0.5–1.8V and exhibits 278pF Ciss, while Q2 features VGS(TH) = −0.5 to −2.2V and 287pF Ciss, enabling matched gate drive timing in half-bridge configurations.
Thermal performance is defined by RθJA = 116°C/W (with 1-inch2 copper pad) and continuous operation from −55°C to +150°C junction temperature. The device integrates body diodes with VSD = 0.7V (Q1) and −0.8V (Q2) at 1A, supporting bidirectional current handling in PWM-controlled power stages.

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC2038LVTQ-7 | Lower RDS(ON): 32mΩ/52mΩ @ 4.5V but higher Qg (9.5nC/9.8nC); same TSOT26 package. | Better conduction loss below 1.5A; less suitable for >1MHz switching due to higher gate charge. | Select when thermal budget dominates over switching frequency constraints, e.g., 12V industrial SMPS with <300kHz operation. |
| SI6926ADQ-T1-GE3 | Higher voltage rating (±40V), larger RDS(ON) (85mΩ/130mΩ @ 4.5V), SO-8 package (not pin-compatible). | Supports wider input range but requires PCB redesign; lacks AEC-Q101 qualification. | Choose only if system requires 36V transient tolerance and automotive qualification is not mandatory. |
Compared with DMC3061SVTQ-13, DMC2038LVTQ-7 trades higher gate drive loss for lower conduction loss, while SI6926ADQ-T1-GE3 sacrifices automotive compliance and board space efficiency for extended voltage robustness-neither offers identical combination of AEC-Q101, TSOT26 footprint, and balanced 4.5V RDS(ON)/Qg performance.

FAQ
What is the maximum safe operating voltage for the DMC3061SVTQ-13's gate terminals?
The absolute maximum gate-source voltage (VGSS) is ±20V for both Q1 and Q2, per the datasheet's Maximum Ratings table. Exceeding this risks oxide breakdown and permanent gate damage. Recommended drive voltage is 4.5V to 10V for Q1 and −4.5V to −10V for Q2 to ensure full enhancement while maintaining margin against transients.
Can the DMC3061SVTQ-13 be used in a synchronous boost converter topology?
Yes-the N-channel device (Q1) can serve as the main switch, while the P-channel device (Q2) functions as the synchronous rectifier on the output side. Its −30V VDSS and −2.7A ID rating support typical 5V-to-12V boost applications, provided gate drive polarity and timing are configured to avoid shoot-through during dead-time intervals.
Does the DMC3061SVTQ-13 require external gate resistors for stable operation?
Gate resistors are recommended: 3Ω for Q1 and 6Ω for Q2, based on the datasheet's switching time test conditions. These values dampen ringing, limit peak gate current, and control dV/dt to prevent false triggering-especially critical in high-noise automotive environments where EMI immunity is required.
How does the thermal performance of DMC3061SVTQ-13 compare between standard and enhanced PCB layouts?
With a minimal FR-4 pad (2oz copper), RθJA is 142°C/W; with a 1-inch² copper pour, it improves to 116°C/W-a 26°C/W reduction. This translates to ~15°C lower junction temperature at 2A continuous current, directly extending lifetime and enabling higher ambient operation in sealed enclosures.
