Nexperia USA Inc. PMZB950UPEYL

Overview

PMZB950UPEYL from Nexperia is a P-channel enhancement-mode Trench MOSFET in a DFN1006B-3 (SOT883B) package, designed for high-side load switching and relay driving. It features a drain-source voltage rating of –20 V, R_DS(on) = 1.02 Ω at V_GS = –4.5 V and I_D = –500 mA, ESD protection >1 kV HBM, and ultra-small footprint (1.0 × 0.6 × 0.37 mm).

For engineers reviewing the PMZB950UPEYL datasheet, PMZB950UPEYL pinout, PMZB950UPEYL application, or PMZB950UPEYL equivalent, this device is selected for space-constrained, low-voltage DC switching where fast turn-on/turn-off (t_d(on) = 2.3 ns, t_f = 6 ns), low gate charge (Q_G(tot) = 1.19 nC), and thermal robustness on FR4 PCBs are critical.

Technical Context

This P-channel MOSFET operates with a gate-source threshold voltage (V_GS(th)) ranging from –0.45 V to –0.95 V at T_j = 25 °C, enabling logic-level drive from 1.8 V–4.5 V microcontrollers. Its trench architecture delivers low R_DS(on) while maintaining tight parametric distribution across temperature.

The device exhibits dynamic characteristics optimized for switching: C_iss = 43 pF, C_oss = 14 pF, and Cr_ss = 8 pF at V_DS = –10 V, supporting efficient high-frequency operation up to several MHz in low-power DC-DC and load-switching topologies.

FAQ

What is the maximum continuous drain current for PMZB950UPEYL at 100 °C ambient?

The maximum continuous drain current is –300 mA at T_amb = 100 °C, as specified in the Limiting Values table. This derating reflects thermal limitations on standard FR4 PCBs with single-sided copper and a 1 cm² drain pad. At 25 °C, the rating increases to –500 mA under identical mounting conditions.

Does PMZB950UPEYL require a gate resistor for typical MCU-driven switching?

A gate resistor is recommended to dampen ringing and control slew rate, especially at higher frequencies. With Q_G(tot) = 1.19 nC and typical MCU GPIO drive strength (~20 mA), a 10–47 Ω series resistor provides stable turn-on/turn-off while limiting peak gate current to safe levels and minimizing EMI.

Can PMZB950UPEYL be used in reverse polarity protection circuits?

Yes-it is suitable for reverse polarity protection in low-voltage systems (≤12 V). When placed in the high-side position with source tied to input and drain to load, it conducts only when input polarity is correct. Its –20 V V_DS rating and low R_DS(on) ensure minimal forward drop and adequate fault blocking.

Is the DFN1006B-3 package compatible with standard reflow profiles?

Yes-the DFN1006B-3 (SOT883B) package is qualified for lead-free reflow per J-STD-020. Recommended profile uses peak temperature of 260 °C for ≤30 seconds, with ramp rates ≤3 °C/s. The footprint shown in Figure 20 (0.35 mm land width, 0.65 mm length, 0.25 mm solder paste deposit) ensures reliable solder joint formation and thermal anchoring.
