Product details
Overview
DMC3021LSD from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in a single SO-8 package, integrating an N-channel (30V, 21mΩ @ 10V) and P-channel (−30V, 39mΩ @ −10V) device. It delivers 8.5A/−7A continuous drain current at 25°C, low gate charge (16.1nC/21.1nC), and fast switching (tF = 8.55ns/22.2ns), enabling high-efficiency synchronous buck converters and dual-rail load switches.
For engineers reviewing the DMC3021LSD datasheet, DMC3021LSD pinout, DMC3021LSD application, or DMC3021LSD equivalent, key selection criteria include verified RDS(ON) matching between channels, SO-8 thermal resistance (50°C/W), gate threshold symmetry (±1.45V/−1.7V), and automotive-grade qualification path via DMC3021LSDQ.
Technical Context
This dual MOSFET implements independent N- and P-channel enhancement-mode transistors sharing a common source configuration in SO-8. The N-channel Q2 features 767pF input capacitance and 105pF reverse transfer capacitance at VDS = 10V, while the P-channel Q1 exhibits 1002pF Ciss and 118pF Crss under −10V bias - enabling precise timing control in half-bridge drivers.
Thermal design is constrained by 2.5W power dissipation and 50°C/W junction-to-ambient resistance on FR-4 PCBs. Gate drive compatibility is ensured by ±20V VGSS rating and matched |Yfs| (8.1S/7S), supporting 4.5V–10V logic-level control without level-shifting.
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 |
|---|---|---|---|
| DMC2038LSD-13 | Higher RDS(ON): 38mΩ/65mΩ @ 4.5V; lower Qg (12.5nC/15.2nC); same SO-8 footprint | Better suited for 3.3V logic-driven battery management where gate drive voltage is limited | Select when VGS < 4.5V is mandatory and 20% higher conduction loss is acceptable |
| Si7852DP-T1-GE3 | Asymmetric package: 3.3mm × 3.3mm TDFN vs. SO-8; 25mΩ/45mΩ @ 10V; 1.2W PD | Enables ultra-compact 2-layer PCB layouts but requires requalification of thermal relief pads | Choose for space-constrained portable designs where SO-8 rework compatibility is not required |
Compared with DMC2038LSD-13, DMC3021LSD provides 30% lower RDS(ON) at 10V drive for higher efficiency in 5V/12V systems; versus Si7852DP, it offers 2.5× higher power dissipation headroom and established SO-8 assembly infrastructure.

FAQ
What is the maximum continuous drain current for each channel at 85°C ambient?
The N-channel (Q2) supports 7.1A and the P-channel (Q1) supports −4.5A at TA = +85°C with device mounted on FR-4 PCB using minimum recommended pad layout. These values reflect thermal derating due to 50°C/W junction-to-ambient resistance and 2.5W power dissipation limit.
Does DMC3021LSD require external gate resistors for stable operation?
No external gate resistors are required for basic switching, as the integrated 1.4Ω (N) and 13Ω (P) gate resistances provide inherent damping. However, a 10Ω series resistor is recommended for EMI suppression in 1MHz+ PWM applications to control dV/dt and reduce ringing on the gate waveform.
Can this device replace discrete N+P MOSFETs in existing SO-8 footprints?
Yes - DMC3021LSD uses standard SO-8 pinout (pin 1=G1, pin 2=S1, pin 3=D1, pin 4=S2, pin 5=D2, pin 6=G2) and matches JEDEC MS-012AC dimensions. No PCB redesign is needed when upgrading from discrete solutions like DMN3021LSD + DMP3021LSD in shared-source configurations.
Is there a halogen-free version available with identical specifications?
Yes - DMC3021LSD is inherently halogen-free and antimony-free per Diodes' "Green" definition (<900ppm Br, <900ppm Cl, <1000ppm Sb), certified to RoHS 3 (2015/863/EU). No alternate part number is required; compliance is built into all production lots marked "e3".
