ZXMHC6A07N8TC - 60V Complementary H-Bridge MOSFET | Diodes Inc
MPN: ZXMHC6A07N8TC ✓ Hoạt độngZXMHC6A07N8TC Tóm tắt
A MOSFET H-bridge is a four-switch topology used to drive bidirectional current through a load (typically a DC motor, solenoid, or piezo element) by selectively activating diagonal pairs of N and P-channel devices. The complementary N+P architecture inside one package eliminates the need for external charge-pump or level-shift circuitry, simplifying PCB layout and reducing BOM count compared with discrete all-N-channel H-bridges that require a high-side bootstrap driver. H-bridge arrays sit at the lowest tier of the power semiconductor family, which itself belongs to the broader discrete semiconductor category.
Key features include low on-resistance achievable with low gate-drive voltage (logic-level compatible at VGS=10V), monolithic die construction that minimizes parasitic inductance between the half-bridges, and a thermally enhanced SO-8 footprint with exposed center pad. The asymmetric N/P ratings (slightly higher RDS(on) on the P-channel) reflect typical silicon area trade-offs in complementary processes, and are well matched for the symmetric switching patterns of H-bridge operation. The device is also characterized for fast switching transitions, which reduces dead-time losses in PWM motor control.
The architecture uses Diodes Incorporated's latest-generation TrenchMOS process, which achieves the low figure-of-merit (RDS(on) x Qg) needed for sub-1 ohm complementary switches in a small outline package. Internal source connections are bonded out individually on the package pins, allowing the four MOSFETs to be used either as a complete H-bridge or as two independent half-bridges for buck/boost converter legs. This dual-use flexibility is a notable advantage over H-bridges predriver/only ICs that lock the user into a fixed topology.
Typical applications include DC motor driver H-bridges in low-voltage appliances, DC-AC inverters for LED backlighting and piezo buzzers, solenoid and valve drivers in industrial controls, and battery-powered robotic actuators. The 60V rating comfortably covers 12V and 24V industrial bus rails with substantial transient headroom.
When designing with this device, ensure the gate-drive timing accounts for the slower P-channel turn-off (typical of PMOS in H-bridges) and provide adequate dead-time in PWM firmware to prevent cross-conduction. Place a low-ESR ceramic bypass capacitor directly at the package to suppress the VDS ringing that arises from the package lead inductance.

12V/24V DC Motor Driver H-Bridge
The ZXMHC6A07N8TC is purpose-built for low-voltage DC motor H-bridge drivers. Its complementary N+P topology eliminates the external charge-pump or bootstrap circuit needed by all-N-channel bridges, reducing BOM count by 4-6 components. The 60V V(BR)DSS comfortably covers 12V and 24V industrial bus rails with 2.5x-5x headroom for motor back-EMF transients at commutation. RDS(on) of 0.25 ohm (N-Ch) at VGS=10V keeps conduction losses under 0.5W per leg at 1A, allowing fan-cooled designs without a heatsink up to roughly 1.5A continuous. For typical PWM frequencies of 20-50 kHz the part's switching losses remain negligible compared to conduction losses. Place the device near the motor connector to minimize the high-frequency switching loop area and reduce radiated EMI.

Solenoid and Valve Driver
Industrial solenoid valves, latching relays, and pneumatic actuators benefit from the ZXMHC6A07N8TC's bidirectional drive capability in a single SO-8 footprint. The H-bridge topology allows direct reversing of a solenoid without external H-bridge driver ICs like the L293D, freeing board area and reducing cost by 30-40% in high-volume designs. The 60V breakdown rating handles the inductive kick from 24V solenoids (which can spike to 60-80V) if a flyback path is provided. The 1.4A P-channel rating is well matched to typical 0.5-1A solenoid holding currents. Use a software-controlled soft-start to limit inrush current when the solenoid is engaged, and add a TVS across the supply for additional transient suppression.

DC-AC Inverter for LED Backlighting
The ZXMHC6A07N8TC is well matched to low-power DC-AC conversion for piezo-element buzzers, small EL lamp drivers, and LED matrix backlight inverters operating below 60V peak. The complementary pair can be configured as a half-bridge with the load returned to a center-tapped transformer, generating a square-wave AC output suitable for driving piezo sounders at 1-4 kHz. The 1.8A N-channel current rating supports LED backlight currents up to 1A per channel in matrix configurations. The monolithic SO-8 construction minimizes the switching loop inductance that causes ringing in discrete H-bridges, reducing the need for snubber components and improving EMC compliance.

Battery-Powered Robotic Actuator
For hobby robotics, small drone gimbal motors, and battery-powered actuator modules running from 2S-6S Li-ion packs (7.4V-22.2V nominal), the ZXMHC6A07N8TC provides a compact bidirectional drive in a footprint smaller than a postage stamp. The 60V rating covers 6S Li-ion fully charged at 25.2V with >2x headroom for regenerative braking spikes. Logic-level gate drive at VGS=10V is compatible with 3.3V MCU outputs via a simple gate-driver charge pump. The 870mW package dissipation supports continuous currents up to approximately 0.7A without a heatsink in still air, ideal for peak-duty-cycle robotic joints where average dissipation is well below the maximum.

Piezo Buzzer Driver
Piezo buzzers used in industrial alarms, medical devices, and IoT notification appliances require a 100-300 VAC drive signal at 1-4 kHz to produce audible sound. The ZXMHC6A07N8TC's complementary half-bridge can drive a small step-up transformer to generate these high-voltage AC levels from a 3.3V or 5V supply. The 60V V(BR)DSS rating limits this topology to buzzers requiring less than approximately 30Vp-p drive, which covers the majority of small SMD piezo elements. The monolithic SO-8 construction keeps the two switching devices in close proximity, minimizing dead-time variation between the N and P transitions and producing a cleaner AC waveform with lower harmonic distortion.

Low-Voltage Fan Speed Controller
Brushless DC (BLDC) fans used in networking equipment, telecom hardware, and server chassis often include a simple reverse-rotation or speed-tap circuit that can be implemented with a ZXMHC6A07N8TC H-bridge. The 60V rating covers 48V PoE rails commonly found in IP phones and small switches. The complementary pair can be wired as a synchronous buck leg to provide efficient PWM speed control of a 12V or 24V fan, with the P-channel handling the high-side switch and the N-channel handling the low-side. The 1.4A continuous P-channel rating supports fans up to approximately 0.8A continuous, covering the majority of 40-80mm fans used in networking and industrial applications.

Ghi chú thiết kế
At continuous 1.4A per P-channel with VIN=24V and average switching duty cycle of 50%, the ZXMHC6A07N8TC dissipates approximately 1.4W in the SO-8 package (theta-JA ~150C/W on a 1oz 1sqin copper pad). This drives the junction temperature ~210C above ambient - well beyond the 150C maximum. Either reduce continuous current to ~0.7A, switch to the ZXMHC6A07T8TA exposed-pad variant (theta-JA ~80C/W), or add a small SOT-23 footprint copper heatsink. Estimated calculation: P = I^2 * RDS(on) = 1.4^2 * 0.40 = 0.78W per leg x 2 active legs ~ 1.5W total.
Place input and output bulk capacitors within 5mm of the SO-8 package to minimize the high-frequency switching loop area. The complementary N+P topology requires a low-impedance ground return - use a continuous ground plane on layer 2 with at least 4 vias stamped, allowing via stitching around the SO-8 thermal pad. Keep gate-drive traces short (under 10mm) and route them away from the drain switching node to minimize capacitive coupling that can cause shoot-through. If using a center-tapped transformer load, place the transformer within 15mm of the package to limit radiated EMI from the switching loop.
Do not exceed 60V VDS - inductive loads (motive, solenoids) can generate kick-back transients well above the supply rail. Add a TVS diode or flyback path rated above the supply but below 60V. The P-channel gate must be driven to VDD or below for full enhancement - leaving it floating or at mid-rail will cause partial turn-on with high RDS(on). Always include dead-time in firmware (1-2us minimum) to prevent cross-conduction when transitioning between forward and reverse modes. Finally, the dual N-channel sources (pins 1 and 3) and dual P-channel drains (pins 5 and 7) are NOT internally connected - the PCB must wire them together if the part is used as a single H-bridge.
