Product details
Overview
ZXGD3009DYTA from Diodes Incorporated is a high-speed, non-inverting single-channel MOSFET gate driver in SOT363 package, delivering up to 1 A peak source/sink current with 40 V supply rating and ±7 V output differential voltage. It enables rapid MOSFET switching in power conversion stages by providing independently controllable turn-on (SOURCE) and turn-off (SINK) paths, reducing EMI and cross-conduction in DC-DC converters and amplifier output stages.
For engineers reviewing the ZXGD3009DYTA datasheet, ZXGD3009DYTA pinout, ZXGD3009DYTA application, or ZXGD3009DYTA equivalent, key selection criteria include its dual-output architecture for asymmetric gate timing control, 3.8 ns typical rise delay at low input resistance, near-zero quiescent current (20 nA), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The ZXGD3009DYTA uses an emitter-follower topology with separate SOURCE and SINK terminals, allowing independent adjustment of MOSFET turn-on and turn-off slew rates via external RC networks. Its high-gain buffer delivers 500 mA output from just 10 mA input, enabling direct drive from low-power controllers without intermediate buffering.
It operates across a wide 40 V supply range (VCC to VEE), supports load capacitances up to 10 nF, and maintains stable switching performance under varying input resistance (100 Ω–10 kΩ). Thermal resistance is 391 °C/W (junction-to-ambient, standard layout), and it is qualified to AEC-Q101 for automotive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Source/Sink Current | 1.58 A / 1.38 A - Enables fast charging/discharging of large gate capacitances (e.g., >1 nF) in high-current MOSFETs |
| Supply Voltage Range | 40 V max (VCC–VEE) - Supports wide-input industrial and automotive power rails without level-shifting |
| Quiescent Supply Current | 20 nA - Eliminates standby power penalty in always-on or battery-backed systems |
| Turn-On Delay (td(rise)) | 3.8 ns (typ.) - Minimizes dead-time uncertainty in synchronous buck or half-bridge topologies |
| Output Differential Voltage | ±7 V - Allows safe operation with gate-source voltage margins under transient conditions |
| ESD Rating (HBM) | 4000 V - Ensures robustness during PCB handling and assembly in high-volume manufacturing |
| Thermal Resistance (RθJA) | 391 °C/W - Defines maximum power dissipation (320 mW) on standard 25 mm × 25 mm 1 oz copper PCB |
Pinout & Package
SOT363 surface-mount package: 6-pin, 2.15 mm × 2.10 mm × 0.95 mm body, matte tin-plated leads, moisture sensitivity level 1, weight ≈ 0.018 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply rail | Connects to high-side gate drive supply; sets upper voltage limit for SOURCE output |
| IN | Logic-level input | Accepts TTL/CMOS-compatible signals; controls both SOURCE and SINK activation |
| VEE | Negative supply rail / ground reference | Reference for sink path and input logic; may be tied to system ground or negative bias |
| SOURCE | Active-high gate drive output | Delivers current to MOSFET gate during turn-on; pin must be routed with low-inductance trace |
| SINK | Active-low gate drive output | Removes gate charge during turn-off; independent control allows optimized fall time and reduced shoot-through risk |
| NC | No connection | Internally unconnected; must remain floating or grounded per layout best practice (not tied to VCC/VEE) |
Key Features
| Feature | Design Value |
|---|---|
| Separate SOURCE and SINK outputs | Enables independent RC tuning of MOSFET turn-on and turn-off edges to suppress EMI and prevent cross-conduction |
| Rugged emitter-follower architecture | Immune to latch-up and shoot-through failures common in CMOS-based drivers under high dV/dt stress |
| Optimized SOT363 pinout | Minimizes parasitic trace inductance between SOURCE/SINK and MOSFET gate, preserving high-speed edge fidelity |
| AEC-Q101 qualification | Validated for automotive under-hood environments including temperature cycling (−55°C to +150°C) and HTRB stress |
| Near-zero quiescent current | Reduces system-level standby power by >99% compared to conventional gate drivers with 1–5 mA IQ |

Equivalent & Alternatives
The following parts are listed as comparable options for similar MOSFET gate driving applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC4427AVOA | Higher 1.5 A peak output but fixed push-pull output (no independent SOURCE/SINK); 6 V–18 V supply only | Lacks independent turn-on/turn-off control; unsuitable for EMI-sensitive or shoot-through-critical designs | Select when cost and board space are prioritized over timing flexibility and automotive qualification |
| LM5113SD | Integrated bootstrap diode and 5 A peak drive; requires external bootstrap capacitor; no AEC-Q101 rating | Designed for high-side/high-frequency synchronous buck; not validated for automotive temperature or reliability stress | Select for >1 MHz switching in industrial DC-DC where AEC-Q101 is not required |
Compared with TC4427AVOA and LM5113SD, ZXGD3009DYTA uniquely provides AEC-Q101 qualification, independent SOURCE/SINK control for EMI optimization, and ultra-low quiescent current-making it optimal for automotive and thermally constrained high-reliability power stages.

FAQ
Can ZXGD3009DYTA drive both high-side and low-side N-channel MOSFETs?
Yes-it supports both configurations. For high-side drive, VEE is referenced to the MOSFET source (e.g., via bootstrap capacitor), and SOURCE drives the gate above source potential. For low-side drive, VEE is grounded, and SINK actively pulls the gate to ground. The separate SOURCE/SINK pins allow independent optimization of each transition.
What is the minimum input drive current needed to achieve full 1 A output?
A 10 mA input current delivers ~500 mA output; full 1.58 A peak source current requires ≥50 mA input drive into the IN pin (per datasheet test condition). This is achievable with most microcontrollers' GPIOs or dedicated PWM controllers without additional buffering.
Is the NC pin on ZXGD3009DYTA required to be left floating?
Yes-the sixth pin is internally unconnected. Diodes Incorporated's recommended layout shows it floating; grounding or connecting it to VCC/VEE may induce parasitic coupling or violate internal isolation boundaries, potentially degrading EMI performance or reliability.
How does ZXGD3009DYTA reduce electromagnetic interference in switching circuits?
By enabling independent control of turn-on (SOURCE) and turn-off (SINK) edges via external RC networks, it allows deliberate slowing of one edge while keeping the other fast-reducing high-frequency spectral content. Its optimized SOT363 pinout also minimizes loop inductance, suppressing voltage spikes that radiate EMI.
