Diodes Incorporated ZXMN6A25KTC

Overview

ZXMN6A25KTC from Zetex Semiconductors is a 60V, 10.7A N-channel enhancement-mode trench MOSFET in DPAK package, optimized for high-efficiency power management with R_DS(on) = 0.050 Ω @ V_GS = 10V and fast switching (t_d(off) = 26.2 ns). It serves as a main switch in DC-DC converters and motor control H-bridge legs.

For engineers reviewing the ZXMN6A25KTC datasheet, ZXMN6A25KTC pinout, ZXMN6A25KTC application, or ZXMN6A25KTC equivalent, key selection criteria include its low gate charge (Q_g = 20.4 nC), body diode recovery (t_rr = 22.0 ns), thermal resistance (R_JA = 12.7 °C/W on 50 mm × 50 mm PCB), and 60V V_(BR)DSS rating for industrial power stage design.

Technical Context

This MOSFET employs a trench-gate structure to simultaneously minimize conduction loss and switching loss. Its low R_DS(on) and fast turn-off delay (26.2 ns) enable high-frequency operation in synchronous buck converters up to 500 kHz.

The device integrates a robust body diode with V_SD = 0.95 V at 5.5 A and t_rr = 22.0 ns, supporting efficient freewheeling in half-bridge topologies without external Schottky diodes.

FAQ

Is ZXMN6A25KTC suitable for 3.3 V logic-level gate drive?

Yes. With V_GS(th) ranging from 1 V to 3 V and R_DS(on) = 0.070 Ω at V_GS = 4.5 V, it achieves full enhancement using standard 3.3 V microcontroller outputs. Gate charge of 20.4 nC ensures minimal driver loading at typical PWM frequencies below 1 MHz.

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

At T_amb = 70°C with standard mounting on 50 mm × 50 mm FR4 PCB, the continuous drain current is 8.6 A. This is derived from the 9.85 W power dissipation rating and linear derating factor of 78.7 mW/°C, validated per datasheet absolute maximum ratings table.

Does ZXMN6A25KTC include a built-in body diode, and is it rated for reverse recovery?

Yes. It features an integrated source-drain body diode with forward voltage V_SD = 0.95 V at 5.5 A and fully characterized reverse recovery parameters: t_rr = 22.0 ns and Q_rr = 21.4 nC at T_j = 25°C, enabling use in synchronous rectification without external diodes.

Can ZXMN6A25KTC be used in parallel configurations?

Yes, but with caution. Its positive temperature coefficient for R_DS(on) supports current sharing; however, layout symmetry, gate drive matching, and thermal coupling must be strictly controlled. Derating to ≤70% of total rated current per device is recommended to ensure balanced conduction and avoid thermal runaway.
