Nexperia USA Inc. PMCPB5530XAX

Overview

PMCPB5530XAX from Nexperia is a complementary N/P-channel Trench MOSFET pair in a single DFN2020-6 (SOT1118) package, rated for 20 V drain-source voltage, with R_DS(on) of 26 mΩ (N-ch) and 50 mΩ (P-ch) at V_GS = ±4.5 V, and AEC-Q101 qualified for automotive-grade reliability. It serves as a compact, thermally enhanced high-speed load switch or half-bridge driver in space-constrained DC-DC converters.

For engineers reviewing the PMCPB5530XAX datasheet, PMCPB5530XAX pinout, PMCPB5530XAX application, or PMCPB5530XAX equivalent, key selection considerations include its dual-channel complementary topology, ultra-thin 0.65 mm profile, exposed drain pad for thermal conduction, and validated performance across -55 °C to 150 °C junction temperature range.

Technical Context

This device integrates two discrete enhancement-mode MOSFETs-TR1 (N-channel) and TR2 (P-channel)-on a single die substrate within a leadless thermal-enhanced DFN package. Its Trench MOSFET architecture enables low gate charge (6.6 nC N-ch / 8.8 nC P-ch) and fast switching (t_r = 2.3 ns N-ch, t_f = 135 ns P-ch), supporting high-frequency operation in synchronous rectification and bidirectional load control.

The complementary pairing allows direct implementation of high-side (P-ch) and low-side (N-ch) switching without external level-shifting circuitry. Thermal design leverages an exposed drain pad with R_th(j-sp) = 10–11 K/W, enabling 1.2 W continuous power dissipation on FR4 PCB with 6 cm² copper pad.

FAQ

What is the maximum continuous drain current for each channel at 100 °C ambient?

At T_amb = 100 °C, the N-channel supports 2.8 A continuous drain current (V_GS = 4.5 V), and the P-channel supports −2.3 A (V_GS = −4.5 V). These values reflect derating from 4.5 A / −3.6 A at 25 °C due to thermal resistance limitations on standard FR4 PCBs with 6 cm² copper pad.

Does PMCPB5530XAX require external gate resistors for stable switching?

No external gate resistors are mandatory for stability, but a 6 Ω series resistor is recommended for both gates to control dV/dt and reduce EMI in high-frequency (>500 kHz) applications. The device's low Q_G (6.6 nC / 8.8 nC) ensures minimal driver loading even with such resistors.

How is thermal performance affected when mounted without the recommended 6 cm² drain pad?

Without the 6 cm² copper pad, R_th(j-a) degrades from 93 K/W to 223 K/W, reducing maximum continuous power dissipation from 1.2 W to 490 mW at 25 °C ambient. This limits usable current to ~2.2 A (N-ch) and ~1.7 A (P-ch) before exceeding 150 °C junction temperature.

Can PMCPB5530XAX be used in linear regulation mode?

It is not optimized for linear operation: R_DS(on) increases significantly with temperature (1.5× at 150 °C), and safe operating area curves show limited DC bias capability beyond 1 A at >10 V V_DS. Use only in saturated switching mode per datasheet SOA limits.
