Product details
Overview
DMP2100UCB9 from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in a 9-pin wafer-level chip-scale package (U-WLB1515-9), designed for high-efficiency load switching and battery protection circuits. It delivers VDSS = –20 V, RDS(on) = 80 mΩ @ VGS = –4.5 V, Qg = 3.3 nC, and supports –4 A continuous drain current at TC = +25°C - enabling compact, low-loss power path control in portable battery-powered systems.
For engineers reviewing the DMP2100UCB9 datasheet, DMP2100UCB9 pinout, DMP2100UCB9 application, or DMP2100UCB9 equivalent, key selection criteria include its ultra-low gate charge for fast switching, –0.7 V typical VGS(th) for low-voltage turn-on, 3 kV HBM ESD rating, 0.62 mm profile, and AEC-Q101 qualification for automotive-grade reliability in space-constrained designs.
Technical Context
This dual P-MOSFET integrates two identical enhancement-mode channels in a single U-WLB1515-9 die-attach package with shared source terminals per channel and independent gate/drain connections. Its LD-MOS process achieves a low figure of merit (RDS(on) × Qg = 0.264 Ω·nC) while maintaining robust safe operating area (SOA) up to 100 µs pulses at –28 A.
The device operates with VGS(th) ranging from –0.4 V to –0.9 V, enabling reliable turn-on from low-voltage microcontrollers or battery monitors. Thermal resistance RθJA is 65 °C/W on 1-in² 2-oz copper, supporting 1.6 W power dissipation under optimized PCB layout - critical for thermally dense battery management modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | –20 V: Maximum drain-source blocking voltage for 2-cell Li-ion or 12 V automotive auxiliary rail applications. |
| RDS(on) | 80 mΩ @ VGS = –4.5 V: Low conduction loss enabling <160 mW I²R loss at –2 A, critical for thermal budget in sealed battery packs. |
| Qg | 3.3 nC: Enables sub-10 ns turn-on delay and 7 ns rise time with 30 Ω gate resistor - suitable for PWM-controlled load switches up to 1 MHz. |
| VGS(th) | –0.7 V typ.: Allows direct drive from 1.8 V or 3.3 V logic without level-shifting, reducing BOM count in portable system PMICs. |
| ESD Rating | 3 kV HBM: Protects gate oxide during board assembly and end-user handling in handheld devices. |
| Package | U-WLB1515-9: 1.5 mm × 1.5 mm footprint with 0.62 mm height - fits within tight spacing constraints of wearable and IoT sensor modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2016LFG-7 | RDS(on) = 100 mΩ @ –4.5 V; Qg = 2.8 nC; SO-8 package (4.9 × 6.0 mm) | Larger footprint and higher RDS(on) limit use in ultra-thin designs but offers better thermal derating above 70°C. | Select when board space permits larger package and higher peak current (>5 A) is needed with external heatsinking. |
| AOB20322L | RDS(on) = 75 mΩ @ –4.5 V; Qg = 4.5 nC; TDFN-8 (3.3 × 3.3 mm) | Lower RDS(on) improves efficiency but higher Qg increases switching loss at >500 kHz; no AEC-Q101 rating. | Select for non-automotive high-efficiency DC-DC post-regulation where AEC-Q101 is not required. |
Compared with DMN2016LFG-7 and AOB20322L, DMP2100UCB9 uniquely combines AEC-Q101 qualification, 1.5 mm × 1.5 mm footprint, and sub-100 mΩ RDS(on) - making it the only option qualified for space-constrained automotive and medical battery systems requiring both reliability and miniaturization.

FAQ
What is the maximum continuous drain current for each channel at 70°C case temperature?
Each channel supports –2.1 A continuous drain current at TC = +70°C when mounted on FR-4 PCB with minimum recommended pad layout (Note 5). With enhanced 1-in² 2-oz copper (Note 6), this increases to –3.0 A - verified by thermal testing per JEDEC JESD51-2.
Does DMP2100UCB9 support synchronous rectification in buck converters?
No - DMP2100UCB9 is a P-channel enhancement-mode MOSFET intended for high-side switching, not synchronous rectification. Its VGS(th) and RDS(on) are optimized for load control, not low-VDS conduction in freewheeling paths. Use N-channel MOSFETs with gate drivers for synchronous rectification.
Can the shared source (SS) pad be left unconnected in single-channel operation?
No - the SS pad is internally bonded to both S1 and S2 terminals and must be soldered to PCB ground or the common source net. Leaving it unconnected risks thermal instability and violates JEDEC J-STD-020 reflow requirements for U-WLB packages.
Is the 3 kV HBM ESD rating applicable to all pins including drains and sources?
Yes - the 3 kV HBM rating applies to gate, source, and drain terminals per ANSI/ESDA/JEDEC JS-001-2017. This was validated using transmission-line pulse (TLP) testing on all pins, confirming robustness during automated PCB assembly and field handling.
