Diodes Incorporated ZXM64P035L3

Overview

ZXM64P035L3 from Zetex is a -35V, -12A P-channel enhancement-mode MOSFET in TO-220 package, featuring R_DS(on) = 0.075 Ω at V_GS = -10V, fast switching (t_d(off) = 40 ns), and low threshold voltage (V_GS(th) = -1.0 V), deployed in Class D audio output stages and motor control power switches.

For engineers reviewing the ZXM64P035L3 datasheet, ZXM64P035L3 pinout, ZXM64P035L3 application, or ZXM64P035L3 equivalent, key selection criteria include negative-channel logic compatibility, thermal resistance (R_θJC = 6.25 °C/W), body diode recovery (Q_rr = 27.8 nC), and gate charge (Q_g = 46 nC) for PWM-driven low-voltage power management.

Technical Context

This P-channel MOSFET operates with enhancement-mode gate control requiring negative V_GS to conduct; its planar high-cell-density structure enables low R_DS(on) and fast transition times (t_r = 6.2 ns, t_f = 29.2 ns) without sacrificing ruggedness.

It integrates a monolithic body diode with V_SD = -0.95 V at I_S = -2.4 A and reverse recovery time t_rr = 30.2 ns under 100 A/μs di/dt, supporting synchronous rectification and bidirectional current handling in half-bridge topologies.

FAQ

Is ZXM64P035L3 suitable for gate driving with +5 V logic?

No. As a P-channel enhancement MOSFET, it requires negative gate-source voltage to turn on. A +5 V signal applied between gate and source yields V_GS = +5 V, keeping the device fully off. Proper operation demands V_GS ≤ -1.0 V, typically achieved using a level-shifting driver or negative supply rail.

What is the maximum safe operating temperature for continuous use?

The junction temperature must not exceed +150°C. With R_θJC = 6.25 °C/W and a typical heatsink R_θSA of ~10 °C/W, the device sustains -12 A continuous current at ambient ≤50°C. Derating is required above 25°C case temperature per the 160 mW/°C linear factor.

Does the body diode support synchronous rectification?

Yes-the integrated body diode has V_SD = -0.95 V at -2.4 A and t_rr = 30.2 ns, enabling controlled freewheeling in half-bridge configurations. However, its Q_rr = 27.8 nC necessitates careful dead-time tuning to avoid cross-conduction with the complementary switch.

Can ZXM64P035L3 replace an N-channel MOSFET in the same position?

No. It cannot substitute directly for an N-channel device due to opposite polarity: P-channel devices conduct with negative V_GS, while N-channel require positive V_GS. Circuit redesign-including gate drive polarity, level shifting, and topology re-evaluation-is mandatory for replacement.
