Product details
Overview
ZXMN6A08GQTA from Diodes Incorporated is a 60V, SOT223-packaged N-channel enhancement-mode MOSFET with RDS(ON) = 0.08 Ω @ VGS = 10V, 5.3A continuous drain current at TA = +25°C, and AEC-Q101 qualification. It serves as a high-reliability load switch or power stage transistor in automotive BLDC motor drives and DC-DC converters.
For engineers reviewing the ZXMN6A08GQTA datasheet, ZXMN6A08GQTA pinout, ZXMN6A08GQTA application, or ZXMN6A08GQTA equivalent, key selection criteria include its 0.08Ω on-resistance at 10V gate drive, 12.3ns turn-off delay, AEC-Q101 qualification, thermal resistance of 32°C/W (on FR-4), and SOT223 package compatibility with high-current PCB layouts.
Technical Context
This MOSFET employs planar silicon technology optimized for low gate charge (QG = 5.8 nC @ 10V) and fast switching (tD(OFF) = 12.3 ns), enabling efficient operation in 200–500 kHz DC-DC topologies. Its 1V gate threshold (VGS(TH) min = 1V) supports direct interface with 3.3V and 5V logic controllers without level shifting.
The device integrates a robust body diode with tRR = 19.2 ns and QRR = 30.3 nC, suitable for synchronous rectification and freewheeling in half-bridge configurations. Thermal design is supported by two distinct RθJA ratings: 32°C/W (high-copper PCB) and 62.5°C/W (standard FR-4), reflecting real-world layout dependencies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - Maximum blocking voltage for 12V/24V automotive bus systems with transient margin |
| RDS(ON) | 0.08 Ω @ VGS = 10V - Enables ≤0.43 W conduction loss at 5.3A, reducing heatsink requirements |
| ID (continuous) | 5.3 A @ TA = +25°C - Supports sustained load switching in engine control modules and ADAS power rails |
| QG | 5.8 nC @ VGS = 10V - Low gate drive power demand for microcontroller-based PWM control |
| tD(OFF) | 12.3 ns - Enables clean dead-time management in half-bridge inverters up to 500 kHz |
| RθJA | 32 °C/W - Achievable with 25 mm × 25 mm 1 oz copper pad; defines minimum PCB copper area for thermal compliance |
| VGS(TH) | 1–2.5 V - Ensures reliable turn-on with standard 3.3V GPIOs and avoids false triggering near ground noise |
Pinout & Package
Package: SOT223 (Type DN), surface-mount, thermally enhanced plastic package with exposed drain tab for PCB heat sinking. Molded plastic meets UL 94V-0 flammability rating; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal (body diode cathode) | Primary current return path; tied to ground plane or low-side reference in high-side switch configurations |
| Pin 2 (Gate) | Control input | High-impedance node requiring <1.4 nC gate charge for full turn-on; sensitive to ESD and ringing |
| Pin 3 (Drain) | Power output / high-side connection | Internally connected to large metal tab; must be soldered to ≥25 mm² copper pour for thermal performance |
| Tab (Drain) | Drain terminal (thermal & electrical) | Electrically and thermally identical to Pin 3; mandatory thermal connection to PCB for RθJA = 32°C/W |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use with PPAP support and IATF 16949 manufacturing-enables direct integration into Tier-1 ECUs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN601DWKQ-7 | RDS(ON) = 0.12 Ω @ 10V; SOT223-3L; QG = 7.2 nC | Higher conduction loss; less suitable for high-current BLDC phases | Prefer where cost sensitivity outweighs efficiency; verify thermal margin with RθJA = 40°C/W |
| IPD25N06S4-1R2 | TO-252 package; RDS(ON) = 1.2 mΩ; QG = 32 nC; higher current (25A) | Requires larger footprint and gate driver due to 32 nC QG; over-specified for <6A loads | Select only when >10A peak current or lower RDS(ON) is mandatory; not drop-in compatible |
Compared with DMN601DWKQ-7 and IPD25N06S4-1R2, ZXMN6A08GQTA delivers optimal balance of low gate charge (5.8 nC), moderate RDS(ON) (0.08 Ω), and AEC-Q101 compliance in compact SOT223-making it ideal for space-constrained, thermally demanding automotive power stages below 6A.

FAQ
Is ZXMN6A08GQTA suitable for high-frequency switching above 1 MHz?
No. While its tD(OFF) is 12.3 ns, the device's Ciss = 459 pF and QG = 5.8 nC result in practical switching limits around 500 kHz in hard-switched topologies. Above this frequency, switching losses dominate, and thermal derating becomes severe-even with optimized gate drive and PCB copper.
Can ZXMN6A08GQTA be used in a high-side configuration with bootstrap gate drive?
Yes. Its VGSS = ±20 V and VGS(TH) = 1–2.5 V make it compatible with standard bootstrap circuits driving 10–12 V gate voltage. However, the SOT223 drain-tab thermal path requires careful PCB layout to avoid localized heating during continuous high-side operation.
What is the maximum safe operating current at 105°C ambient temperature?
At TA = +105°C, the device's linear derating factor is 31 mW/°C (PD = 3.9 W at 25°C). With RDS(ON) ≈ 0.11 Ω at 105°C junction, the maximum continuous current is approximately 2.3 A-verified using PLOSS = I² × RDS(ON) ≤ (3.9 W − (105−25) × 0.031 W) = 1.42 W.
Does the SOT223 package support reflow soldering per J-STD-020?
Yes. The device is rated Moisture Sensitivity Level 1 (MSL-1), meaning it may be stored indefinitely at ≤30°C/60% RH and subjected to standard Pb-free reflow profiles (peak 260°C, 20–40 sec above 217°C) without baking or special handling.
