The Diodes Incorporated DMG6968U-7 is a 20V N-channel enhancement-mode MOSFET in a compact SOT-23 surface-mount package. It combines low on-resistance, low input capacitance, fast switching, low leakage, and up to 2kV ESD protection, making it suitable for load switching, DC/DC conversion, battery-powered systems, and other low-voltage power applications.
The device is rated for 20V drain-to-source voltage and ±12V gate-to-source voltage. Under the specified FR-4 PCB condition with 2oz copper, thermal vias, and a one-square-inch bottom copper area, continuous drain current reaches 6.5A at 25°C and 5.2A at 70°C. Pulsed drain current is rated up to 30A.
Maximum RDS(on) is only 25mΩ at VGS = 4.5V, 29mΩ at 2.5V, and 36mΩ at 1.8V, making the device well suited to low-voltage logic-level gate drive. Gate threshold voltage ranges from 0.5V to 0.9V.
Typical input capacitance is 151pF, while output and reverse-transfer capacitances are 91pF and 32pF. Typical total gate charge is 8.5nC at 4.5V, with 1.6nC Qgs and 2.8nC Qgd.
Maximum power dissipation is 1.3W under the specified PCB condition, with 157°C/W junction-to-ambient thermal resistance. Operating and storage temperatures range from -55°C to +150°C. The exact DMG6968U-7 is supplied in 3,000-piece tape-and-reel packaging, with MSL Level 1 classification and RoHS/Green compliance.
Diodes Incorporated currently lists the DMG6968U as NRND — Not Recommended for New Design, with DMN2024U identified as the recommended device for new designs. The standard DMG6968U-7 is distinct from the automotive DMG6968UQ version.
