Product details
Overview
DMP2088LCP3 from Diodes Incorporated is a P-channel enhancement-mode MOSFET optimized for compact load switching in battery-powered systems, featuring -20V VDSS, 88mΩ RDS(ON) @ VGS = -8V, -2.9A continuous drain current at 25°C, and X2-DSN1006-3 package with 0.30mm profile - used in handheld device battery protection circuits.
For engineers reviewing the DMP2088LCP3 datasheet, DMP2088LCP3 pinout, DMP2088LCP3 application, or DMP2088LCP3 equivalent, key selection criteria include low gate charge (Qg = 1.5nC), thermal resistance (RθJA = 217°C/W on FR-4), and -55°C to +150°C operating range for space-constrained portable electronics.
Technical Context
This MOSFET operates as a high-side load switch in battery management paths, leveraging its negative threshold voltage (-0.7V to -1.2V) and low RDS(ON) to minimize conduction loss during active discharge control. Its gate drive compatibility with 3.3V/5V logic enables direct interface with microcontroller GPIOs without level-shifting.
The device integrates a body diode with VSD = -0.75V @ IS = -0.5A and QRR = 1.0nC, supporting bidirectional current handling in reverse-polarity protection and charge path isolation. Transient thermal response is characterized by RθJA(t) curves for pulse-width-dependent power dissipation up to 15A IDM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20V - maximum blocking voltage for battery-side high-side switching in 3.7V Li-ion systems with headroom margin |
| RDS(ON) | 88mΩ @ VGS = -8V - ensures ≤220mW conduction loss at 1.5A load current in portable applications |
| ID (continuous) | -2.9A @ TA = +25°C - supports sustained operation in USB-C PD sink detection and smart battery cutoff circuits |
| Qg | 1.5nC - enables fast turn-on/off with minimal gate driver power, critical for PWM-controlled load switching |
| RθJA | 217°C/W - defines thermal derating on standard FR-4 PCB; limits usable DC current to ~1.1A at ambient 60°C |
| VGS(TH) | -1.0V typical - allows full enhancement with 1.8V–3.3V logic-level gate drive, eliminating need for charge pumps |
| Package | X2-DSN1006-3 - 1.0mm × 0.6mm footprint with 0.30mm height, enabling placement under thin-film shields in smartphones |
Pinout & Package
Package: X2-DSN1006-3 - ultra-thin, leadless, three-terminal surface-mount package with exposed drain pad for thermal relief.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Current return path for load current | Connected to system ground or battery negative; ties to internal substrate for lowest inductance source loop |
| 2 (Gate) | Control electrode for channel modulation | High-impedance input requiring <50nA leakage; routed away from noisy digital traces to prevent false turn-on |
| 3 (Drain) | Main current path from load to battery positive | Exposed copper pad on bottom surface - must be soldered to large thermal pad for effective heat spreading |
Key Features
| Feature | Design Value |
|---|---|
| Low Qg & Qgd | Qg = 1.5nC, Qgd = 0.22nC - reduces switching energy loss and EMI during fast transitions in portable PMICs |
| 0.30mm profile | Height constraint met for stacked PCB assemblies in wearables and hearing aids where Z-space is ≤0.4mm |
| Lead-free & Halogen-free | Meets RoHS 3 (2015/863/EU) and Diodes "Green" definition (<900ppm Br+Cl, <1000ppm Sb) for eco-compliant consumer designs |
| Small footprint | 1.0mm × 0.6mm outline - occupies 40% less board area than comparable SOT-23-3 devices, freeing routing space in dense layouts |
| Low RDS(ON) at low VGS | 105mΩ @ VGS = -4.5V - enables efficient operation directly from single-cell Li-ion (3.0–4.2V) without auxiliary bias rails |
Applications
| Battery Protection Circuit | USB-C Port Power Switching |
|---|---|
|
Use Scenario: Prevents reverse-current flow and over-discharge in single-cell Li-ion packs during standby or fault conditions. IC Role / Device Role / Timing Role: High-side MOSFET acting as bidirectional blocking switch controlled by battery fuel gauge IC or protection ASIC.

Use Scenario: Isolates charging circuitry from main battery when earbuds are docked, preventing parasitic drain during storage. IC Role / Device Role / Timing Role: Always-on load switch managed by low-power MCU; remains latched off until insertion detection. Use Value: IDSS = -100nA max at -16V ensures <1μA quiescent current, extending case runtime by >3 months per full charge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMP2078LCA3 | Lower RDS(ON) (60mΩ @ -8V), same X2-DSN1006-3 package, but higher Qg (2.2nC) | Better conduction efficiency at high current; slightly slower switching due to increased gate charge | Select when minimizing I²R loss dominates over switching speed, e.g., always-on battery disconnect |
| DMG2305UVT-7 | Same -20V rating, larger SOT-523 package (1.7mm × 0.9mm), 50mΩ RDS(ON) @ -4.5V, higher thermal resistance (300°C/W) | Higher power handling on thermally robust boards; incompatible with ultra-thin Z-height constraints | Choose when board layout permits larger footprint and thermal performance outweighs size requirements |
Compared with DMP2088LCP3, DMP2078LCA3 improves conduction loss but trades off switching speed, while DMG2305UVT-7 sacrifices miniaturization for lower RDS(ON) and higher current capability - selection depends on whether board area, thermal budget, or efficiency is the dominant constraint.

FAQ
Is DMP2088LCP3 still in production?
No - Diodes Incorporated officially discontinued DMP2088LCP3 in 2022, marking it as obsolete with no new wafer starts. However, Aetrix Electronics maintains legacy stock for last-time buy, repair, and long-lifecycle industrial programs with full traceability and date-code verification.
What is the recommended replacement for DMP2088LCP3?
Diodes recommends DMP2078LCA3 as the direct functional replacement: same X2-DSN1006-3 package, improved RDS(ON) (60mΩ vs. 88mΩ @ -8V), and identical pinout. It requires no layout change and supports identical gate drive voltages, making it a drop-in upgrade for most applications.
Can DMP2088LCP3 be used in automotive applications?
No - DMP2088LCP3 is not AEC-Q101 qualified and lacks PPAP documentation or IATF 16949 manufacturing certification. For automotive-grade P-channel switches, Diodes offers the DMP2065UQ (AEC-Q101 qualified) in comparable small-outline packages with extended temperature validation.
What is the maximum safe operating temperature for DMP2088LCP3?
The absolute maximum junction temperature is +150°C, but sustained operation above +125°C degrades reliability. With RθJA = 217°C/W on FR-4, the practical maximum ambient temperature is +60°C at 1.0A continuous drain current - thermal derating must follow Figure 11 SOA curves for pulsed loads.
