Product details
Overview
ZXGD3114N7TC from Diodes Incorporated is a 600V active ORing MOSFET controller in SO-7 package, designed to drive ultra-low RDS(ON) N-channel MOSFETs as ideal diodes in high- or low-side PSU configurations. It features a -3mV turn-off threshold (±2mV tolerance), <600ns turn-off time, and supports ±600V rail operation with <1mA quiescent current - enabling >98% power transfer efficiency in telecom redundant power systems.
For engineers reviewing the ZXGD3114N7TC datasheet, ZXGD3114N7TC pinout, ZXGD3114N7TC application, or ZXGD3114N7TC equivalent, key selection criteria include drain voltage rating (600V), gate drive sink/source capability (5A/2A), turn-off propagation delay (<400ns), and compatibility with high-voltage (±400V) ORing topologies in N+1 redundant servers.
Technical Context
The ZXGD3114N7TC implements a precision differential amplifier-based detector that monitors VDS across an external MOSFET to control gate drive state. Its turn-off threshold is fixed at -3mV with ±2mV tolerance, ensuring reliable reverse-current blocking even under temperature variation (-50°C to +150°C).
It integrates a high-current gate driver capable of 5A sink and 2A source peak current, with internal 12V gate clamp when VCC >12V. The device operates from 4V–20V VCC, supports both high-side (+400V) and low-side (-400V) configurations, and delivers <50mW standby power at 48V input.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Drain Voltage Rating | 600V - Enables direct connection to ±400V telecom/server bus rails without external level-shifting. |
| Turn-Off Threshold | -3mV (±2mV) - Detects sub-millivolt reverse conduction to block fault currents before bus collapse. |
| Turn-Off Propagation Delay | <400ns - Limits reverse current duration during PSU failure, preserving common bus stability. |
| Gate Sink/Source Current | 5A / 2A peak - Drives large-area MOSFET gates rapidly for <695ns rise and <131ns fall times (CL=47nF). |
| Quiescent Supply Current | 260µA typical - Enables <50mW standby consumption in 48V systems, critical for energy-efficient data centers. |
| VCC Range | 4V–20V - Supports direct bias from auxiliary rails or resistive dividers off HV buses. |
| Operating Temperature | -50°C to +150°C - Qualified for industrial and telecom environments with extended thermal margins. |
Pinout & Package
Package: SO-7 (Surface-mount, molded plastic, UL 94V-0, 0.074g weight, moisture sensitivity Level 1). Pin 1–7 arranged linearly with GND/GND/VCC/GATE/PGND/PGND/DRAIN configuration optimized for low-inductance high-current paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 GND | Signal Ground Reference | Connects to MOSFET source and system ground; forms reference for differential VDS sensing. |
| 3 VCC | Power Supply Input | Accepts 4–20V supply; requires local X7R decoupling capacitor; primary thermal path for heat dissipation. |
| 4 GATE | MOSFET Gate Driver Output | Sources up to 2A / sinks up to 5A; clamped to 12V if VCC >12V; external RG sets turn-on speed. |
| 5, 6 PGND | Power Ground Return | Low-impedance return for high-current gate drive and MOSFET source; shares thermal pad with VCC. |
| 7 DRAIN | Drain Voltage Sense Input | Detects MOSFET VDS polarity and magnitude; triggers turn-off when VDS exceeds -3mV threshold. |
Key Features
| Feature | Design Value |
|---|---|
| Active ORing Control Logic | Differential amplifier with -3mV threshold enables precise, temperature-stable ideal diode behavior without external op-amps. |
| High-Voltage Rail Compatibility | 600V drain rating allows direct integration into ±400V telecom and server power buses without isolation components. |
| Ultra-Fast Fault Response | <600ns total turn-off time (tD(FALL) + tF) prevents reverse current from collapsing shared bus voltage during PSU faults. |
| Low-Power Standby Operation | 260µA IQ at 48V yields <50mW idle loss - critical for always-on infrastructure equipment meeting ENERGY STAR® Tier 2. |
| Thermally Optimized SO-7 Layout | Pins 3 (VCC) and 5–6 (PGND) serve as primary thermal conduction paths; recommended 10mm×10mm copper pads reduce RθJA to 191°C/W. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar active ORing controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5050-1MK/NOPB | 48V max VIN, 50mV turn-off threshold, no 600V drain rating | Limited to low-voltage DC distribution (≤48V); unsuitable for telecom HV rails | Select only for sub-50V systems where cost sensitivity outweighs HV capability. |
| TPS2412DR | 80V max VIN, adjustable threshold (10–100mV), 2.5µs turn-off | Requires external resistor network for threshold setting; too slow for 400V bus protection | Prefer for mid-voltage (24–80V) industrial controls where programmability justifies latency trade-off. |
Compared with LM5050-1MK/NOPB and TPS2412DR, the ZXGD3114N7TC uniquely supports ±400V rail operation with sub-millivolt threshold and nanosecond turn-off - making it the only viable choice for telecom and high-density server ORing where bus stability and efficiency are non-negotiable.

FAQ
What is the maximum allowable VCC voltage for ZXGD3114N7TC?
The absolute maximum VCC is 25V, but the recommended operating range is 4V–20V. Exceeding 20V does not improve performance and risks exceeding thermal limits due to increased internal power dissipation. The gate driver clamps output to 12V above GND regardless of VCC, so higher supply voltages only increase quiescent loss without functional benefit.
Can ZXGD3114N7TC be used in high-side configuration with negative input rails?
Yes - the device supports true bipolar operation with drain voltage ranging from -3V to +600V relative to GND. In negative-rail applications (e.g., -48V telecom), the DRAIN pin connects to the negative bus, and the MOSFET is placed between bus and load, enabling ideal diode behavior for reverse-current blocking during source failure.
How does the -3mV turn-off threshold behave over temperature?
The threshold drift is ±2mV over full -50°C to +150°C range, confirmed by characterization data in DS40000 Rev.2. At 125°C, measured VT remains between -5mV and -1mV, ensuring consistent reverse-current detection without false triggering or delayed shutdown across industrial operating conditions.
Is external gate resistor required for stable operation?
An external gate resistor (RG) is optional but recommended to control MOSFET turn-on dV/dt and prevent oscillation. Typical values range from 1Ω to 10Ω depending on MOSFET Qg; values below 1Ω risk ringing, while >10Ω extends turn-on time beyond optimal efficiency. No resistor is needed for basic functionality, as the internal driver provides sufficient control.
