Product details
Overview
DMC1030UFDBQ-7 from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in a single U-DFN2020-6 (Type B) package, integrating an N-channel (12V, 34mΩ @ 4.5V, 5.1A) and P-channel (-12V, 59mΩ @ -4.5V, -3.9A) device for bidirectional power control. It supports automotive load switching and portable power adaptor applications with AEC-Q101 qualification, PPAP capability, and IATF 16949 manufacturing.
For engineers reviewing the DMC1030UFDBQ-7 datasheet, DMC1030UFDBQ-7 pinout, DMC1030UFDBQ-7 application, or DMC1030UFDBQ-7 equivalent, this dual-channel discrete solution offers verified low RDS(ON) at 1.5–4.5V gate drive, ESD-protected gates, and thermal performance validated to 150°C junction temperature under pulsed and steady-state conditions.
Technical Context
This complementary MOSFET pair implements independent N- and P-channel channels sharing a common source configuration in a monolithic U-DFN2020-6 (Type B) die layout. Each channel features gate threshold voltages of 0.4–1.0V (N) and -0.4 to -1.0V (P), enabling logic-level operation down to 1.5V supply rails.
Dynamic parameters include matched input capacitance (Ciss ≈ 1003/1028 pF), low gate resistance (Rg = 11.3/19.6 Ω), and fast switching with tD(ON)/tD(OFF) of 4.4/18.8 ns (N) and 5.6/30.7 ns (P) under defined test conditions, supporting high-frequency power management.

FAQ
What is the maximum junction temperature rating for DMC1030UFDBQ-7?
The device is rated for continuous operation from -55°C to +150°C junction temperature, with thermal characteristics validated per JEDEC JESD51-14 standards using a 1"×1" FR-4 test board. The 150°C limit applies to both steady-state and pulsed conditions, and the SOA curve confirms safe operation up to 100ms pulses at 35A (N) and -25A (P).
Does DMC1030UFDBQ-7 support 1.8V logic-level gate drive?
Yes - the N-channel device delivers 50mΩ RDS(ON) and the P-channel delivers 115mΩ at VGS = 1.8V and -1.8V respectively, enabling direct interface with 1.8V microcontrollers and PMICs without level-shifting. Gate threshold voltages are specified at 0.4–1.0V (N) and -0.4 to -1.0V (P), ensuring reliable turn-on margin.
How is the thermal pad on the U-DFN2020-6 (Type B) package intended to be used?
The exposed thermal pad (Pin 4/S2) must be soldered to a dedicated PCB copper pour connected to system ground. Diodes' recommended pad layout specifies a 0.65mm × 0.65mm central pad with eight 0.15mm thermal vias to inner ground planes. This configuration achieves the published RθJA of 92°C/W and prevents thermal derating above 85°C ambient.
Is DMC1030UFDBQ-7 suitable for reverse-voltage protection in automotive systems?
Yes - the integrated P-channel MOSFET provides active reverse-polarity protection with 59mΩ RDS(ON) at -4.5V gate drive, limiting voltage drop to <236mV at 4A. Its -12V VDSS, AEC-Q101 qualification, and 4mJ avalanche energy rating meet ISO 16750-2 requirements for automotive load-dump and jump-start scenarios.
