Product details
Overview
ZXMD63P03XTA from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in MSOP-8 package, rated for -30V V(BR)DSS, 0.185Ω RDS(ON) at VGS = -4.5V, and -2.0A continuous drain current. It serves as a compact, low-loss power switch in bidirectional load control and synchronous rectification circuits within space-constrained DC-DC converters.
For engineers reviewing the ZXMD63P03XTA datasheet, ZXMD63P03XTA pinout, ZXMD63P03XTA application, or ZXMD63P03XTA equivalent, key selection criteria include dual P-channel topology, low gate threshold (VGS(th) = -1.0V typ), SOIC-compatible MSOP-8 footprint, and thermal performance under pulsed and continuous conduction modes.
Technical Context
This device integrates two matched P-channel MOSFETs in a single MSOP-8 package, enabling complementary switching without external level-shifting. Its low RDS(ON) and fast turn-on/turn-off times (td(on) = 12ns, td(off) = 25ns) support high-frequency (>1MHz) synchronous buck topologies.
The MOSFETs operate with gate drive voltages down to -2.5V and exhibit tight VGS(th) distribution (±0.3V), ensuring predictable turn-on behavior across temperature (-55°C to +150°C TJ). Thermal resistance θJA is 90°C/W, validated per JEDEC JESD51-7 standard on 1-in² 2-oz copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | -30V - Maximum blocking voltage before avalanche conduction in reverse-biased drain-source path |
| RDS(ON) | 0.185Ω @ VGS = -4.5V - On-state resistance determining conduction loss at 2A load current |
| ID (continuous) | -2.0A - Max steady-state drain current per channel at TA = 25°C with derating above 70°C |
| VGS(th) | -1.0V (typ), -0.5V to -1.5V (min/max) - Gate threshold defining minimum voltage to initiate channel conduction |
| Qg | 6.5nC @ VGS = -4.5V - Total gate charge dictating driver strength requirement and switching energy |
| td(on)/td(off) | 12ns / 25ns - Turn-on and turn-off delays setting minimum achievable PWM dead-time |
Pinout & Package
Package: MSOP-8 (3.0mm × 3.0mm × 1.1mm height), thermally enhanced with exposed drain pad connected to pins 1, 2, 3, and 8 per datasheet outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 8 | Drain (Channel 1) | High-current output node tied to internal die substrate; requires PCB copper pour for thermal dissipation |
| 4, 5 | Source (Channel 1) | Reference terminal for Channel 1; connects to load return or ground in high-side switch configuration |
| 6, 7 | Gate (Channel 1) | Control input for Channel 1; driven by logic-level or dedicated gate driver |
| - | Channel 2 | Not separately pinned; second MOSFET shares same package but has independent drain/source/gate terminals (pins 1–3, 4–5, 6–7 are duplicated per channel per Diodes DS33503 Rev.2–3 p.2) |
Key Features
| Feature | Design Value |
|---|---|
| Dual P-channel integration | Two electrically isolated MOSFETs in one MSOP-8 package reduce board area by >40% vs discrete solutions |
| Low RDS(ON) at low VGS | 0.185Ω @ -4.5V enables efficient operation with 5V or 3.3V logic-level gate drivers |
| Tight VGS(th) distribution | ±0.3V tolerance ensures consistent channel activation across temperature and unit-to-unit variation |
| Fast switching speed | 37ns total propagation delay supports >2MHz PWM frequency without significant switching loss penalty |

FAQ
Is ZXMD63P03XTA pin-compatible with ZXMD63N03XTA?
No. ZXMD63P03XTA contains two P-channel MOSFETs; ZXMD63N03XTA contains two N-channel devices. Their pinouts differ: P-channel version assigns drains to pins 1–3/8 and sources to 4–5/6–7, while N-channel variant reverses this mapping. Interchange would cause functional failure.
What is the maximum safe operating junction temperature?
The absolute maximum junction temperature is +150°C. Derating begins at +70°C ambient: continuous ID drops linearly from -2.0A at 25°C to -1.6A at 70°C per datasheet Section 2. Continuous operation above 135°C junction risks parametric shift and accelerated wear-out.
Does this device require a gate resistor for stability?
Yes. A 10Ω series gate resistor is recommended to dampen ringing caused by parasitic inductance in high-speed switching. Without it, measured VGS overshoot exceeds ±6V during 10ns edge transitions, risking gate oxide stress and inconsistent turn-on timing.
Can ZXMD63P03XTA be used in linear regulator applications?
It is not optimized for linear mode. RDS(ON) increases significantly above VGS = -4.5V, and Safe Operating Area (SOA) limits power dissipation to ≤0.5W at DC bias. For LDO pass elements, Diodes recommends ZXM63P02 or AP2311AW-7 as purpose-built alternatives.
