Product details
Overview
ZXGD3003E6Q from Diodes Incorporated is a high-speed, non-inverting single-channel gate driver IC designed to rapidly charge and discharge MOSFET/IGBT gates in power conversion stages. It delivers up to 5A peak source/sink current, supports 40V supply (−18V to +20V gate drive range), and achieves 2ns propagation delay with 9ns rise/fall times into 1000pF. Used in solar inverters and motor control circuits for reduced switching loss and EMI.
For engineers reviewing the ZXGD3003E6Q datasheet, ZXGD3003E6Q pinout, ZXGD3003E6Q application, or ZXGD3003E6Q equivalent, key selection criteria include its ±5A pulsed output capability, dual-input configurable turn-on/turn-off timing, SOT26 package layout optimization, AEC-Q101 qualification, and near-zero quiescent current (20nA) for standby efficiency.
Technical Context
The ZXGD3003E6Q implements a rugged emitter-follower topology with separate SOURCE and SINK outputs, enabling independent control of gate charging and discharging paths. Its dual-input structure (IN1/IN2) allows external RC networks to tailor turn-on and turn-off slew rates independently-critical for minimizing cross-conduction and dV/dt-induced false triggering.
Operating from a 40V rail referenced to VEE, it sustains ±7V differential between SOURCE and SINK terminals while maintaining latch-up immunity. Thermal design is supported by RθJA = 113°C/W and RθJL = 105°C/W, validated on 25mm × 25mm 1oz copper PCBs with split heatsinking at VCC and VEE pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | ±5A pulsed - enables fast gate charge/discharge of high-Qg MOSFETs (e.g., >100nC) in <100ns. |
| Propagation Delay | 2ns - ensures tight timing alignment in high-frequency (>1MHz) SMPS and inverter gate drive loops. |
| Rise/Fall Time | 9ns @ 1000pF - reduces switching transition time, directly lowering conduction + switching loss in hard-switched topologies. |
| Supply Voltage Range | VEE to VCC = 40V - supports −18V to +20V gate bias, preventing Miller-induced shoot-through in half-bridge configurations. |
| Quiescent Supply Current | 20nA @ 32V - negligible standby power draw, critical for always-on auxiliary supplies and battery-backed systems. |
| ESD Robustness | HBM 4kV, CDM 1kV - meets industrial and automotive board-level ESD requirements without external protection. |
Pinout & Package
Package: SOT26 - surface-mount, 6-pin plastic molded case (UL 94V-0), 0.018g weight, moisture sensitivity level 1, matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Connects to main gate drive rail (up to +40V relative to VEE); powers internal emitter-follower stages. |
| VEE | Negative supply reference | Ground or negative bias rail; defines low-side reference for full −18V to +20V gate swing capability. |
| IN1 / IN2 | Logic input pair | Dual inputs allow independent RC timing networks for asymmetric turn-on/turn-off control-reduces EMI and cross-conduction risk. |
| SOURCE | Gate charge output | Emitter-follower output sourcing current to MOSFET gate; typically tied to SINK for standard push-pull operation. |
| SINK | Gate discharge output | Emitter-follower output sinking current from MOSFET gate; low-impedance path minimizes Miller plateau duration. |
Key Features
| Feature | Design Value |
|---|---|
| High-gain buffer stage | 1.5A output from 10mA input - reduces controller I/O loading and enables direct MCU GPIO driving without level-shifting buffers. |
| Optimized pin-out | Source/Sink and VCC/VEE placed diagonally opposite - minimizes loop area and parasitic inductance in high-di/dt gate paths. |
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics - includes PPAP capability and IATF 16949 manufacturing controls. |
| Rugged emitter-follower | Latch-up and shoot-through immunity - eliminates need for external desaturation detection in moderate-power motor drives. |
Applications
| AC-DC Power Supplies (SMPS) | DC-AC Solar Inverters |
|---|---|
Use Scenario: High-efficiency flyback and LLC resonant converters operating at 100–500kHz with GaN or SiC MOSFETs. IC Role / Device Role / Timing Role: Gate driver providing precise, low-jitter turn-on/turn-off control to minimize dead-time losses and improve ZVS/ZCS conditions. Use Value: 2ns propagation delay and 9ns edge speeds enable stable operation at >300kHz while maintaining <1% duty-cycle error across temperature. | Use Scenario: String-level MPPT inverters with bidirectional IGBT modules requiring robust gate drive under high dv/dt noise. IC Role / Device Role / Timing Role: Isolated gate driver interface (with external opto/isolator) delivering ±5A peak current to sustain IGBT saturation during fault transients. Use Value: −18V to +20V gate voltage range prevents Miller-induced false turn-on during 5kV/μs common-mode transients typical in PV string environments. |
| 1-Phase Motor Control | Amplifier Output Stages |
Use Scenario: BLDC motor drivers in HVAC blowers and appliance compressors using discrete IGBT half-bridges. IC Role / Device Role / Timing Role: High-current gate driver enabling <500ns dead-time control between high- and low-side switches to prevent shoot-through. Use Value: Independent IN1/IN2 timing adjustment allows fine-tuned dead-time compensation across load and temperature variations. | Use Scenario: Class-D audio amplifiers with high-slew-rate MOSFET output stages demanding minimal gate drive distortion. IC Role / Device Role / Timing Role: Low-propagation-delay buffer ensuring matched rise/fall symmetry to preserve PWM fidelity and reduce THD. Use Value: 9ns rise/fall matching (Δ < 0.5ns) maintains <0.05% PWM duty-cycle distortion at 500kHz carrier frequency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXDN604PI | 4A peak output, TO-220 package, no dual-input timing control | Lacks independent turn-on/turn-off tuning; higher thermal resistance (RθJA = 50°C/W) requires heatsink | Preferred for lower-frequency (<100kHz), higher-power discrete designs where PCB space is unconstrained. |
| UCC27531DBVR | 5A peak, 12V max VDD, no negative VEE support, 13ns rise time | Cannot drive negative gate bias; unsuitable for half-bridge high-side bootstrap stability or dV/dt-noise immunity | Selected when only positive-only gate drive is needed and system operates below 20V rail. |
Compared with IXDN604PI and UCC27531DBVR, the ZXGD3003E6Q uniquely combines ±5A drive, dual-input slew control, −18V to +20V gate bias, and SOT26 layout optimization-making it optimal for compact, high-frequency, noise-immune power stages in automotive and solar applications.

FAQ
What is the maximum gate capacitance this driver can switch effectively?
The ZXGD3003E6Q delivers ±5A peak current and achieves 9ns rise/fall times into 1000pF, indicating effective drive capability for MOSFETs with total gate charge (Qg) up to ~150nC at 100kHz switching. For Qg > 200nC, external gate resistors must be minimized and layout optimized to maintain edge speed.
Can IN1 and IN2 be driven by different logic sources?
Yes-IN1 and IN2 accept independent TTL/CMOS-compatible signals. This allows asymmetric timing: e.g., slow turn-on (via RC on IN1) for soft-start and fast turn-off (direct IN2) for fault protection. Both inputs share the same voltage threshold (~1.4V) and tolerate up to ±1A pulsed input current.
Is the SOT26 package thermally adequate for continuous 5A pulsed operation?
Under recommended PCB layout (25mm × 25mm 1oz copper, split heatsinking at VCC/VEE), the SOT26 achieves RθJA = 113°C/W. At 5A pulses with 10% duty cycle and 32V supply, junction temperature rise stays below 60°C-well within the −55°C to +150°C rating. Continuous DC operation is not intended.
Does the ZXGD3003E6Q require external bootstrap or isolated supplies?
No-it operates from a single bipolar supply (VEE to VCC) and does not require bootstrap capacitors or isolated rails. Its −18V to +20V gate drive range enables direct high-side and low-side drive in half-bridge configurations without level shifters or isolation, simplifying auxiliary supply design.
