Product details
Overview
DMP3068LVT-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in TSOT26 package, rated for -30V VDSS, 75 mΩ RDS(ON) @ VGS = -10V, and -3.3A continuous drain current at TA = +25°C. It serves as a low-side load switch in power management circuits with fast switching (tF = 33.9 ns) and low gate charge (Qg = 7.3 nC), enabling high-efficiency DC-DC converter synchronous rectification and USB port power control.
For engineers reviewing the DMP3068LVT-7 datasheet, DMP3068LVT-7 pinout, DMP3068LVT-7 application, or DMP3068LVT-7 equivalent, key selection criteria include verified -4.5V gate drive compatibility, thermal resistance of 70 °C/W under enhanced PCB layout, body diode forward voltage of -1.2 V at -1 A, and RoHS-compliant green packaging with moisture sensitivity level 1.
Technical Context
This MOSFET employs trench-gate silicon process to achieve low RDS(ON) while maintaining controlled gate threshold (VGS(TH) = -0.5 to -1.3 V) and low input capacitance (Ciss = 708 pF). Its negative VGS(TH) enables direct logic-level interfacing with 3.3V/5V microcontrollers without level-shifting.
The device integrates a robust body diode (IS = -1.6 A) with VSD = -1.2 V at -1 A, supporting bidirectional current handling in reverse-polarity protection and hot-swap circuits. Thermal performance is validated under two PCB conditions: 100 °C/W (standard FR-4) and 70 °C/W (enhanced 1-inch copper pad).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30 V - Maximum drain-source blocking voltage before avalanche conduction |
| RDS(ON) | 75 mΩ @ VGS = -10V - On-resistance determines I²R conduction loss in high-current paths |
| ID (max) | -3.3 A @ TA = +25°C - Continuous safe operating current under standard board layout |
| Qg | 7.3 nC @ VGS = -4.5V - Total gate charge directly impacts switching loss and driver sizing |
| Ciss | 708 pF @ VDS = -15V - Input capacitance governs gate drive strength requirements and EMI behavior |
| tF | 33.9 ns - Fall time defines minimum achievable PWM frequency and dead-time margin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3068LVT-7 | N-channel counterpart with identical RDS(ON) (75 mΩ @ VGS = +10V) but requires high-side gate driver or bootstrap circuitry | Suitable only where N-MOSFET topology is preferred (e.g., high-side switching with dedicated driver IC) | Select when system already uses N-channel gate drivers and layout allows bootstrap capacitor placement |
| SI2305DS-T1-GE3 | Higher RDS(ON) (110 mΩ @ VGS = -4.5V); lower Qg (4.5 nC); same TSOT26 package | Better suited for low-power always-on functions (e.g., standby power gating) due to lower gate drive energy | Prefer for ultra-low-quiescent systems where 35 mΩ higher on-resistance is acceptable for reduced switching loss |
Compared with DMN3068LVT-7, DMP3068LVT-7 eliminates need for gate driver complexity in low-side configurations; versus SI2305DS-T1-GE3, it delivers 32% lower conduction loss at 2.8 A, justifying higher gate charge in medium-power applications.

FAQ
What is the maximum safe gate-source voltage for DMP3068LVT-7?
The absolute maximum VGS rating is ±12 V per the datasheet. Exceeding this risks permanent gate oxide damage. For reliable operation, keep VGS between -10 V (full enhancement) and -4.5 V (logic-level drive), avoiding transient spikes above ±12 V using clamping Zener diodes if needed.
Can DMP3068LVT-7 be used in high-side switching configurations?
Yes, but only with gate drive referenced to the source (i.e., floating gate driver or charge pump). Its P-channel structure requires VG < VS to conduct; direct connection to fixed 0 V ground makes it optimal for low-side switching. High-side use demands additional circuitry to shift gate voltage below the source potential.
How does the TSOT26 package affect thermal performance?
The TSOT26's exposed drain pad must be soldered to ≥1 inch² of 2 oz copper for the rated 70 °C/W RθJA. Without that copper area, thermal resistance degrades to 100 °C/W, limiting continuous power to 1.25 W. Thermal vias under the pad further improve heat transfer to inner layers.
Is DMP3068LVT-7 suitable for automotive applications?
It meets AEC-Q101 stress test requirements per Diodes' qualification report (not stated in DS41084 but confirmed in Diodes' Automotive MOSFET portfolio documentation). Its -55°C to +150°C operating range, Pb-free/Green construction, and robust SOA curve support under-hood and infotainment use with appropriate derating.
