Product details
Overview
ZXMP10A18KQTC from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -100V VDSS, 150 mΩ RDS(ON) at VGS = -10 V, and -15 A continuous drain current at TC = +25°C; it is AEC-Q101 qualified and used in automotive DC-DC converters, power-management functions, disconnect switches, and motor control circuits.
For engineers reviewing the ZXMP10A18KQTC datasheet, ZXMP10A18KQTC pinout, ZXMP10A18KQTC application, or ZXMP10A18KQTC equivalent, key selection criteria include its -100V breakdown voltage, low gate threshold (-2 to -4 V), 100% production-tested UIS capability, TO252 (DPAK) thermal performance (RθJC = 1.75°C/W), and AEC-Q101 qualification status for automotive deployment.
Technical Context
This MOSFET operates as a high-side or low-side switching device in automotive power systems, with gate threshold voltage tightly specified between -2 V and -4 V at ID = -250 µA, enabling reliable turn-on with standard logic-level gate drivers. Its RDS(ON) remains stable across junction temperatures up to +150°C, supported by normalized on-resistance variation data in Figures 6–7.
The device features fast switching dynamics (tD(ON) = 4.9 ns, tF = 17.9 ns), low total gate charge (Qg = 26.9 nC), and robust avalanche capability (EAS = 78 mJ, IAS = -12.5 A), making it suitable for hard-switched topologies requiring repetitive unclamped inductive energy handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -100 V - Withstands reverse drain-source voltage up to 100 V without breakdown, enabling use in 48 V automotive bus and higher-voltage DC-DC stages. |
| RDS(ON) | 150 mΩ @ VGS = -10 V - Delivers low conduction loss at full rated current, reducing I²R heating in high-current power paths. |
| ID (continuous) | -15 A @ TC = +25°C - Supports sustained load currents typical of motor drive H-bridge legs and battery disconnect circuits. |
| EAS | 78 mJ - Specifies single-pulse avalanche energy handling, critical for reliability in inductive load switching without external snubbers. |
| RθJC | 1.75°C/W - Enables efficient heat transfer from junction to case when mounted on copper thermal pads, supporting >70 W power dissipation under heatsink conditions. |
| Qg | 26.9 nC - Determines gate drive power requirement and switching speed; compatible with standard automotive gate drivers (e.g., UCC27531). |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive electronics, including temperature cycling, HTRB, and ESD, supporting PPAP submission. |
Pinout & Package
Package: TO252 (DPAK), surface-mount, thermally enhanced plastic package with exposed drain pad for improved heat dissipation. Dimensions per Diodes Inc. outline drawing: D = 6.10 mm, E = 6.58 mm, H = 9.91 mm, L = 1.59 mm, b3 = 5.33 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (D) | Main current-carrying terminal (exposed pad) | Connected to PCB thermal pad; primary path for high-current conduction and heat extraction to board copper. |
| Gate (G) | Control input | Receives negative gate-source voltage to turn on P-channel device; requires < -2 V to initiate conduction. |
| Source (S) | Reference terminal for gate drive and current return | Serves as common node for gate drive reference and body diode anode; tied to higher potential in high-side configurations. |
Key Features
| Feature | Design Value |
|---|---|
| 100% UIS tested in production | Guarantees avalanche ruggedness per unit, eliminating need for system-level derating in inductive switching applications. |
| Low RDS(ON) at -6 V gate drive | 190 mΩ enables operation with reduced gate drive voltage, simplifying bias design in 12 V automotive systems. |
| Fast switching with low Qgd/Qg ratio | Qgd = 10.2 nC / Qg = 26.9 nC = 0.38 - Reduces Miller plateau duration and improves immunity to dv/dt-induced turn-on. |
| AEC-Q101 qualification + PPAP support | Validated for automotive use with documented change control, traceable lot records, and IATF 16949 manufacturing. |
| Halogen- and antimony-free "Green" construction | <900 ppm Br, <900 ppm Cl, <1000 ppm Sb - Complies with automotive environmental directives and end-of-life recycling requirements. |
Applications
| Automotive DC-DC Converters | High-Side Battery Disconnect Switch |
|---|---|

IC Role / Device Role / Timing Role: Low-side or high-side switch in half-bridge configuration, commutated at ≤20 kHz PWM frequency. Use Value: Robust body diode (VSD = -0.8 V typ.) handles freewheeling current; RθJC = 1.75°C/W supports thermal management without heatsinks. |
Use Scenario: Power sequencing and rail enable for microcontrollers, CAN transceivers, and sensor interfaces in BCMs. IC Role / Device Role / Timing Role: Controlled power switch activated via PMIC output or discrete logic signal. Use Value: Gate threshold range (-2 to -4 V) ensures clean turn-on with 3.3 V or 5 V logic; RoHS/Green compliance meets OEM material declarations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMP10H400SK3 | VDSS = -100 V, RDS(ON) = 120 mΩ @ -10 V, Qg = 22.5 nC, TO252 package | Lower RDS(ON) and gate charge improve efficiency in high-frequency switching; newer revision with updated process. | Select for new designs requiring higher efficiency and longer product lifecycle; replaces ZXMP10A18KQTC where layout compatibility allows. |
| IPB180P04P4L-02 | VDSS = -40 V, RDS(ON) = 1.8 mΩ @ -10 V, TO263 package, AEC-Q101 qualified | Lower voltage rating but significantly lower on-resistance; larger package with higher thermal mass. | Use only in 12 V systems where < -40 V rating suffices; not drop-in due to different voltage class and footprint. |
Compared with DMP10H400SK3 and IPB180P04P4L-02, the ZXMP10A18KQTC offers balanced performance for legacy 48 V/12 V dual-rail automotive designs but lacks the efficiency gains of newer generations; its AEC-Q101 qualification remains valid, though Diodes recommends migration to DMP10H400SK3 for new projects.

FAQ
Is ZXMP10A18KQTC recommended for new designs?
No - Diodes Incorporated explicitly states "THE ZXMP10A18KQ IS NOT RECOMMENDED FOR NEW DESIGNS. PLEASE USE THE DMP10H400SK3." This reflects process improvements and enhanced specifications in the replacement part, while maintaining TO252 packaging and functional equivalence for most applications.
What is the maximum safe operating temperature for ZXMP10A18KQTC?
The device has an operating junction temperature range of -55°C to +150°C. Its absolute maximum TJ is +150°C, validated by SOA curves (Figure 12) and transient thermal resistance data (Figure 13); sustained operation above this limit risks parametric shift or catastrophic failure.
Does ZXMP10A18KQTC include an integrated body diode?
Yes - it features a built-in parasitic body diode with forward voltage VSD = -0.8 V (typ.) at IS = -3.5 A and TJ = 25°C. This diode conducts source-to-drain current during freewheeling phases and is characterized in Figure 9 across temperature.
How is the TO252 package thermally optimized for ZXMP10A18KQTC?
The TO252 (DPAK) package uses an exposed drain pad soldered directly to a large PCB copper area, achieving RθJC = 1.75°C/W. Thermal performance depends on pad size, copper thickness, and internal layer connections - Diodes specifies minimum pad dimensions and recommends 2 oz copper with thermal vias to inner ground planes.
