Product details

Overview

ZXMD63C02XTC from Diodes Incorporated (formerly Zetex) is a dual-channel enhancement-mode MOSFET in a single MSOP-8 package, integrating one N-channel (20 V, 2.4 A, 0.13 Ω R_DS(on)) and one P-channel (–20 V, –1.7 A, 0.27 Ω R_DS(on)) device. It enables compact, high-efficiency synchronous rectification and bidirectional power control in low-voltage DC–DC converters and load-switching circuits.

For engineers reviewing the ZXMD63C02XTC datasheet, ZXMD63C02XTC pinout, ZXMD63C02XTC application, or ZXMD63C02XTC equivalent, key selection criteria include complementary channel matching, low gate charge (6 nC N-ch / 5.25 nC P-ch), fast switching (td(off) ≤16.4 ns), SOIC-compatible footprint, and thermal performance under 1.04 W at T_A = 25°C with dual-die derating.

Technical Context

This dual MOSFET supports complementary switching topologies where coordinated N- and P-channel drive eliminates external timing control. Its matched threshold voltages (V_GS(th) = ±0.7 V typ) and symmetric dynamic parameters (C_iss = 350 pF / 290 pF, Q_g = 6 nC / 5.25 nC) simplify gate driver design for half-bridge and H-bridge configurations.

The device operates across –55°C to +150°C junction temperature, with thermal resistance R_θJA = 120°C/W (dual-die FR4 layout) and linear derating of 8.3 mW/°C above 25°C. Body diode characteristics (V_SD = ±0.95 V, t_rr = 15–21.7 ns) support synchronous rectification without external Schottky diodes.

Key Specifications

Parameter	Value and Actual Design Meaning
N-Channel V_BRDSS	20 V - Supports 12 V input rails with 67% margin against transients
P-Channel V_BRDSS	–20 V - Enables symmetric negative-rail operation in dual-supply systems
N-Ch R_DS(on) @ 4.5 V	0.13 Ω - Delivers ≤300 mW conduction loss at 1.7 A continuous current
P-Ch R_DS(on) @ –4.5 V	0.27 Ω - Maintains <500 mW loss at –1.2 A, suitable for low-duty-cycle high-side switches
Total Gate Charge (N/P)	6.0 / 5.25 nC - Enables efficient 1–2 MHz switching with standard 5 V logic-level drivers
Thermal Resistance (dual-die)	120 °C/W - Requires minimal copper area (25 mm × 25 mm 1 oz) for 1.04 W dissipation
Switching Time (td(off))	13.5 / 16.4 ns - Limits dead-time requirements to <25 ns in synchronous buck designs

Pinout & Package

MSOP-8 package (JEDEC MO-187, 3.0 × 4.9 mm body, 0.65 mm pitch); thermally enhanced for surface-mount assembly on FR4 PCBs with single-sided 1 oz copper.

Pin/Terminal	Circuit Role	Design Meaning
1	N-Channel Source	Common source node for N-ch; tied to ground or low-side return path
2	N-Channel Drain	Power output node for N-ch; connects to load or inductor switch node
3	N-Channel Gate	Logic-level control input; requires no level-shifting for 3.3/5 V microcontrollers
4	P-Channel Source	Common source node for P-ch; connects to positive rail or high-side supply
5	P-Channel Drain	Power output node for P-ch; shares drain connection with N-ch in back-to-back configuration
6	P-Channel Gate	Inverted logic control; active-low drive simplifies high-side gate timing
7	NC	No internal connection; electrically isolated for layout routing flexibility
8	NC	No internal connection; unused pad for mechanical stability and thermal relief

Key Features

Feature	Design Value
Complementary N+P pairing	Single-package integration eliminates board space and layout mismatch between discrete channels
Low gate threshold (±0.7 V)	Enables direct drive from 1.8 V and 3.3 V logic without gate boosters or level shifters
Matched dynamic capacitance	C_iss/C_oss symmetry (350/290 pF & 120/120 pF) ensures balanced turn-on/turn-off timing
Low-profile MSOP-8	Height ≤1.1 mm allows use in space-constrained portable and automotive modules
Fast body diode recovery	t_rr = 15–21.7 ns reduces cross-conduction losses in synchronous rectifiers

Applications

Bidirectional Load Switch

Synchronous Buck Converter

Use Scenario: Reversible power path control in USB-C PD sink applications requiring safe insertion/removal and reverse-current blocking.

IC Role / Device Role / Timing Role: Dual-MOSFET acts as back-to-back switch with N-ch controlling forward current and P-ch enabling reverse conduction during hot-swap events.

Use Value: Eliminates need for external OR-ing controllers; R_DS(on) matching ensures <100 mΩ total path resistance in both directions.

Use Scenario: High-efficiency 5 V → 3.3 V step-down conversion in FPGA I/O banks with tight thermal constraints.

IC Role / Device Role / Timing Role: N-ch serves as synchronous rectifier (low-side switch), P-ch as high-side switch - eliminating external bootstrap circuitry.

Use Value: Achieves >92% efficiency at 2 A load due to combined R_DS(on) of 0.4 Ω and Q_g-optimized switching.

Motor Driver Half-Bridge

Hot-Swap Power Sequencer

Use Scenario: Low-voltage (≤12 V) brushed DC motor control in battery-powered robotics with direction reversal capability.

IC Role / Device Role / Timing Role: N-ch and P-ch form complementary half-bridge legs; gate timing controlled by PWM with programmable dead time.

Use Value: Fast td(off) (≤16.4 ns) and matched C_iss reduce shoot-through risk and enable 500 kHz PWM operation.

Use Scenario: Controlled power-up of multiple subsystems (e.g., sensor array + MCU core) in industrial IoT edge nodes.

IC Role / Device Role / Timing Role: P-ch controls main rail enable; N-ch monitors and clamps inrush via current-sense feedback loop.

Use Value: Integrated dual topology replaces two discrete MOSFETs and discrete current-limit IC, reducing BOM count by 3 parts.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual N+P-channel MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMC2038LVT	R_DS(on) = 0.115 Ω (N) / 0.22 Ω (P) at 4.5 V; lower Q_g (4.8/4.1 nC); same MSOP-8	Better efficiency at high-frequency switching (>1 MHz); tighter V_GS(th) tolerance (±0.2 V)	Select when optimizing for ultra-low conduction loss and minimal gate drive power
SI6926DQ	R_DS(on) = 0.125 Ω (N) / 0.25 Ω (P); higher thermal resistance (150 °C/W); SO-8 package	Larger footprint but higher power handling (1.5 W); less sensitive to PCB copper area	Select when thermal margin is constrained and board space permits SO-8 layout

Compared with DMC2038LVT and SI6926DQ, ZXMD63C02XTC offers balanced trade-offs: mid-range R_DS(on), proven reliability in legacy designs, and optimal thermal performance on standard MSOP-8 layouts - making it ideal for cost-sensitive, medium-power DC–DC and load-switching applications where layout density matters.

FAQ

What is the maximum continuous drain current for each channel at 70°C ambient?

At T_A = 70°C, the N-channel supports 1.9 A and the P-channel supports –1.35 A with V_GS = ±4.5 V, per Absolute Maximum Ratings table. These values reflect thermal derating from the 25°C ratings (2.4 A / –1.7 A) and assume standard surface-mount conditions on FR4 with 1 oz copper.

Can ZXMD63C02XTC be used in a common-drain (source-follower) configuration?

Yes - both channels support source-follower operation. The N-channel's low V_GS(th) (0.7 V typ) and P-channel's symmetric –0.7 V threshold allow rail-to-rail output swing with minimal headroom loss. However, gate drive must respect polarity: N-ch gate driven positive relative to source, P-ch gate driven negative relative to source.

Is the MSOP-8 package lead-free and RoHS compliant?

Yes - ZXMD63C02XTC is manufactured with lead-free terminations and complies with EU RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1 (unlimited floor life at ≤30°C/85% RH). The device is marked "Pb-Free" and carries full material declarations per Diodes Incorporated's compliance documentation.

Does the device include integrated ESD protection on gate terminals?

No - ZXMD63C02XTC does not integrate gate ESD protection diodes. External 10 kΩ current-limiting resistors and/or TVS clamps are recommended on gate traces, especially in automated assembly or high-static environments, to prevent damage from human-body-model (HBM) discharges exceeding ±2 kV.
