Diodes Incorporated ZXMP3A16DN8TA

Overview

ZXMP3A16DN8TA from Diodes Incorporated (formerly Zetex Semiconductors) is a dual P-channel enhancement-mode MOSFET in SOIC-8 package, rated for -30V V_DS, 0.045Ω R_DS(on) at V_GS = -10V, and -5.5A continuous drain current. It delivers low-loss power switching in compact motor drive and LCD backlighting circuits with fast 3.8ns turn-on delay and integrated body diode.

For engineers reviewing the ZXMP3A16DN8TA datasheet, ZXMP3A16DN8TA pinout, ZXMP3A16DN8TA application, or ZXMP3A16DN8TA equivalent, key selection criteria include verified dual P-channel topology, SOIC-8 thermal derating (1.25W @ T_A=25°C, one active die), gate threshold of -1.0V, and body diode reverse recovery time of 21.7ns - all critical for synchronous buck and H-bridge designs.

Technical Context

This device integrates two identical P-channel trench MOSFETs in a single SOIC-8 package, sharing common source terminals per channel and enabling half-bridge or dual independent switching configurations. Its low R_DS(on) and fast switching (t_r = 6.5ns, t_f = 21.4ns) are achieved via optimized trench gate structure and low gate charge (Q_g = 29.6nC at V_GS = -10V).

Thermal performance is defined across three mounting conditions: 100°C/W (25mm × 25mm single-sided copper), 70°C/W (short-duration pulse), and 60°C/W (dual-die equal-power operation). The body diode exhibits V_SD = -0.85V at I_S = -3.6A and Q_rr = 16.1nC, supporting efficient freewheeling in DC-DC converters.

FAQ

What is the maximum safe operating junction temperature for ZXMP3A16DN8TA?

The absolute maximum junction temperature is +150°C, and the device is characterized for continuous operation across -55°C to +150°C. Thermal derating begins at 25°C ambient, with linear reduction of 10mW/°C for single-die operation (1.25W max at 25°C) and 14mW/°C for dual-die mode (1.8W max at 25°C), per datasheet Issue 2, page 3.

Can ZXMP3A16DN8TA be used in synchronous rectification without external Schottky diodes?

Yes - its integrated body diode has V_SD = -0.85V at -3.6A and t_rr = 21.7ns, enabling efficient synchronous rectification in DC-DC converters up to 500kHz. No external diode is required, though layout must minimize source inductance to preserve switching speed.

Is the SOIC-8 footprint of ZXMP3A16DN8TA compatible with JEDEC MS-012AC standard?

Yes - mechanical dimensions match JEDEC MS-012AC: 4.90mm × 3.90mm body, 1.27mm lead pitch, and 0.016–0.050mm lead length. Pin 1 identifier is a beveled corner, and thermal pad is absent - confirming full compatibility with standard SOIC-8 reflow profiles and pick-and-place equipment.

Does ZXMP3A16DN8TA support gate drive from 3.3V microcontrollers?

Yes - with V_GS(th) = -1.0V (typical) and guaranteed turn-on at V_GS ≤ -2.5V, the device fully enhances using 3.3V logic outputs. At V_GS = -3.3V, R_DS(on) rises to 0.070Ω (per datasheet page 4), delivering -3.4A continuous current - sufficient for most low-power motor and backlight applications.
