Product details

Overview

ZXMP7A17KQ from Diodes Incorporated is a -70V, 160mΩ (at V_GS = -10V) P-channel enhancement-mode MOSFET in TO252 (DPAK) package, rated for -5.7A continuous drain current at T_A = +25°C. It features low gate threshold (-1.0V typ), fast switching (t_R = 3.4ns), and integrated body diode with V_SD = -0.85V @ -2.0A - optimized for DC-DC converters and automotive power disconnect switches.

For engineers reviewing the ZXMP7A17KQ datasheet, ZXMP7A17KQ pinout, ZXMP7A17KQ application, or ZXMP7A17KQ equivalent, key selection criteria include its AEC-Q101 qualification, R_DS(ON) stability across temperature, gate charge (Q_g = 9.6nC @ -5V), and thermal resistance (R_θJA = 30°C/W on 50mm × 50mm FR4).

Technical Context

This trench-structured P-channel MOSFET delivers low conduction loss and high-speed switching via optimized gate oxide and channel geometry. Its -1.0V typical V_GS(TH) enables direct logic-level drive from 3.3V/5V controllers, while Q_gd/Q_gs ratio of 2.1 supports clean turn-off in high-side configurations.

The device integrates a robust body diode with t_RR = 29.8ns and Q_RR = 38.5nC, enabling efficient synchronous rectification and flyback recovery in buck and half-bridge topologies. Thermal design is supported by R_θJA = 30°C/W (50mm × 50mm 2oz Cu) and I_T = -9.2A continuous source rating.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-70V - supports 48V automotive and industrial bus systems with 20% derating margin
R_DS(ON)	160mΩ @ V_GS = -10V - ensures ≤0.9W conduction loss at -5.7A in steady-state operation
I_D (cont)	-5.7A @ T_A = +25°C - suitable for medium-power load switching up to ~30W at 12V input
Q_g	9.6nC @ V_GS = -5V - enables <100ns total switching time with 10Ω gate resistor
t_R/t_F	3.4ns / 8ns - minimizes overlap loss in PWM-driven half-bridge and Class-D audio stages
V_GS(TH)	-1.0V (typ) - compatible with 3.3V GPIO control without level-shifting circuitry
R_θJA	30°C/W - requires ≥50mm × 50mm 2oz copper pad for full 4.17W power dissipation at ambient

Pinout & Package

Package: TO252 (DPAK), surface-mount, single-ended heat sink capable, 3-terminal configuration with exposed drain tab for thermal and electrical connection.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path output / heat sink interface	Electrically connected to package tab; must be soldered to large copper area for thermal management and low-inductance return path
Gate	Control electrode	Receives negative voltage relative to source to turn on; sensitive to ESD (±20V max rating)
Source	Reference node / current return	Serves as common reference for gate drive and load return; body diode anode is internally tied here

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive power management per stress test requirements including HTGB, HTRB, and TC
Low R_DS(ON) × Q_g figure-of-merit	1.54Ω·nC - balances conduction and switching losses in 100–500kHz DC-DC designs
Fast body diode recovery	t_RR = 29.8ns, Q_RR = 38.5nC - reduces reverse-recovery spikes and EMI in synchronous rectifiers
Lead-free & halogen-free	Meets RoHS 3 (2015/863/EU) and Diodes' "Green" definition (<900ppm Br/Cl, <1000ppm Sb)
Low V_GS(TH) distribution	-1.0V typ, no minimum spec - ensures reliable turn-on with 3.3V microcontrollers without external biasing

Applications

Automotive Load Disconnect

Industrial DC-DC Converter High-Side Switch

Use Scenario: Isolating battery-fed ECUs during sleep mode to meet ISO 16750 quiescent current limits.

IC Role / Device Role / Timing Role: High-side P-channel switch controlling main power rail; operates in static on/off state with infrequent transitions.

Use Value: 160mΩ R_DS(ON) limits voltage drop to <0.9V at 5A, preserving system efficiency while meeting AEC-Q101 reliability requirements.

Use Scenario: Regulating 24V input to 5V/3.3V rails in programmable logic controllers using synchronous buck topology.

IC Role / Device Role / Timing Role: Synchronous rectifier in low-side position; commutates at 300kHz with controlled dV/dt.

Use Value: Fast t_R/t_F (3.4ns/8ns) and low Q_RR minimize shoot-through risk and improve light-load efficiency by >3% vs. standard MOSFETs.

Class-D Audio Output Stage

Motor Control H-Bridge Low-Side Switch

Use Scenario: Driving speaker loads in automotive infotainment amplifiers with PWM carrier frequencies above 300kHz.

IC Role / Device Role / Timing Role: Complementary P-channel switch in half-bridge output stage; handles bidirectional current with body diode conduction.

Use Value: V_SD = -0.85V ensures low forward drop during dead-time conduction, reducing distortion and thermal stress in 10W+ output stages.

Use Scenario: Controlling brushed DC motors in HVAC actuators and seat adjusters with PWM duty cycles from 5% to 100%.

IC Role / Device Role / Timing Role: Low-side switch in H-bridge; subjected to repetitive pulsed currents up to -17.7A (IDM).

Use Value: R_DS(ON) = 250mΩ @ V_GS = -4.5V enables direct MCU GPIO drive while maintaining <1.1W loss at 2.1A RMS motor current.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMG1012T	R_DS(ON) = 200mΩ @ -4.5V; Q_g = 5.2nC; TO236 package (SOT-23)	Lower current rating (-2.8A), smaller footprint, higher R_DS(ON) - suited for space-constrained sub-10W loads	Select when board area is critical and thermal budget allows higher conduction loss
IPD250N06L3	R_DS(ON) = 2.5mΩ @ -4.5V; TO252; 60V rating; AEC-Q101 qualified	Higher cost, lower R_DS(ON), but larger gate charge (Q_g = 22nC) increases drive complexity	Choose for high-efficiency 48V systems where <0.1V drop at 5A is mandatory and gate driver can support 22nC

Compared with DMG1012T, ZXMP7A17KQ offers 43% lower R_DS(ON) and 2× higher current capability in the same DPAK footprint; versus IPD250N06L3, it trades 65× higher R_DS(ON) for 2.3× lower Q_g, simplifying gate drive in cost-sensitive 12–24V applications.

FAQ

Is ZXMP7A17KQ suitable for hot-swap applications?

Yes - its -70V V_DSS, low R_DS(ON), and robust SOA support controlled inrush limiting in 12V/24V hot-swap circuits. The device's 17.7A pulsed drain rating and 30°C/W thermal resistance enable brief overloads without thermal runaway when properly heatsinked.

What is the maximum safe operating temperature for ZXMP7A17KQ?

The absolute maximum junction temperature is +150°C, with continuous operation limited by power dissipation and PCB thermal design. At T_A = +70°C, the derated continuous drain current is -4.6A (Note 6), and R_DS(ON) increases ~25% over its 25°C value due to positive temperature coefficient.

Does ZXMP7A17KQ require a gate resistor for stability?

A gate resistor (typically 10–47Ω) is recommended to dampen ringing caused by gate-drain capacitance (Crss = 42.5pF) and PCB inductance. Without it, fast edges may excite parasitic oscillations, increasing EMI and risking false turn-on during high-dV/dt transients in motor or inductive load switching.

Can ZXMP7A17KQ replace N-channel MOSFETs in high-side configurations?

No - it is a P-channel device designed for high-side switching with negative gate drive relative to source. Replacing an N-channel high-side switch would require inverting the control signal and adjusting gate drive voltage range; it cannot be used as a drop-in replacement without circuit redesign.
