NXP Semiconductors PMZB600UNE315

Overview

PMZB600UNE from Nexperia is a 20 V, N-channel enhancement-mode Trench MOSFET in a DFN1006B-3 (SOT883B) leadless ultra-small surface-mount package, featuring 470 mΩ R_DS(on) at V_GS = 4.5 V and I_D = 0.6 A, 1 kV HBM ESD protection, and optimized for low-side load switching in space-constrained portable electronics.

For engineers reviewing the PMZB600UNE datasheet, PMZB600UNE pinout, PMZB600UNE application, or PMZB600UNE equivalent, this page delivers verified electrical parameters, thermal derating curves, gate charge characteristics, junction-to-ambient thermal resistance, and validated alternative MOSFETs for compact DC-DC and battery-powered signal-path designs.

Technical Context

This discrete N-channel MOSFET uses Trench technology to achieve low on-resistance in a 1.0 × 0.6 × 0.37 mm footprint, supporting fast switching with 0.7 nC total gate charge and 9.2 ns rise time. Its gate threshold voltage (0.45–0.95 V) enables direct drive from 1.8 V logic, while its 20 V V_DS rating targets single-cell Li-ion and 3.3 V/5 V rail applications.

The device operates across –55 °C to 150 °C junction temperature, with normalized R_DS(on) rising to 1.3× at 125 °C and 1.7× at 150 °C. Thermal resistance from junction to ambient is 360 K/W on standard FR4, dropping to 40 K/W to solder point-critical for thermal management in unheatsinked PCB layouts.

Key Specifications

Pinout & Package

DFN1006B-3 (SOT883B) is a 3-terminal, leadless plastic package measuring 1.0 × 0.6 × 0.37 mm with exposed drain pad for thermal conduction. The package uses bottom-surface solder lands only-no leads-and requires reflow-compatible footprint per Figure 20 in the datasheet.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel low-voltage MOSFET applications.

Compared with PMZB600UNE, DMN10H020LPS-13 trades ESD immunity and thermal profile for marginal cost reduction, while AO3400 sacrifices miniaturization and low-threshold drive for higher voltage headroom and legacy package compatibility-neither is pin-compatible, and both require PCB layout revision.

FAQ

What is the maximum continuous drain current for PMZB600UNE at 100 °C ambient temperature?

The PMZB600UNE supports 0.4 A continuous drain current at T_amb = 100 °C, as specified in Table 5 (Limiting values). This derating reflects thermal limitations of the DFN1006B-3 package on standard FR4 PCBs; performance improves with enhanced copper area or forced airflow. Always verify junction temperature using R_th(j-a) = 360 K/W in thermal calculations for PMZB600UNE.

Does PMZB600UNE support 1.8 V logic-level gate drive?

Yes, PMZB600UNE supports 1.8 V logic-level gate drive due to its low gate threshold voltage (V_GS(th) = 0.45–0.95 V typ). At V_GS = 1.8 V, R_DS(on) is 845–1300 mΩ (Table 7), enabling functional switching at reduced current-ideal for ultra-low-power wake-up circuits. Full 0.6 A capability requires ≥4.5 V gate drive for PMZB600UNE.

What is the thermal resistance from junction to solder point for PMZB600UNE?

The thermal resistance from junction to solder point (R_th(j-sp)) for PMZB600UNE is 40 K/W, as listed in Table 6. This value assumes mounting on FR4 with tin-plated copper and a standard footprint. It enables accurate thermal modeling when the drain pad is connected directly to a thermal via or internal plane-critical for predicting junction temperature under sustained load in PMZB600UNE designs.

Can PMZB600UNE be used in automotive applications?

No, PMZB600UNE is not automotive-qualified. Per Section 15.3 of the datasheet, Nexperia explicitly states that unless designated as automotive qualified, products like PMZB600UNE are unsuitable for automotive use. It lacks AEC-Q101 qualification, extended temperature validation, and automotive-specific reliability testing-use only in consumer, industrial, or computing applications per PMZB600UNE specifications.

What is the gate-drain charge (Q_GD) of PMZB600UNE and why does it matter?

The gate-drain charge (Q_GD) of PMZB600UNE is 0.1 nC (typical), measured at V_DS = 10 V, I_D = 0.6 A, V_GS = 4.5 V, and T_j = 25 °C (Table 7). Q_GD directly impacts switching speed and Miller plateau duration; low Q_GD minimizes shoot-through risk in half-bridge configurations and improves efficiency in high-frequency PMZB600UNE-based converters.
