NXP Semiconductors PMZB1200UPEYL

Overview

PMZB1200UPE from Nexperia is a P-channel enhancement-mode Trench MOSFET in a DFN1006B-3 (SOT883B) package, rated for -30 V drain-source voltage, 410 mA continuous drain current at V_GS = -4.5 V, and 1.2 Ω typical R_DS(on) at 25 °C - designed for high-side load switching in space-constrained portable electronics.

For engineers reviewing the PMZB1200UPE datasheet, PMZB1200UPE pinout, PMZB1200UPE application, or PMZB1200UPE equivalent, key selection criteria include its ultra-thin 0.37 mm profile, low gate threshold of -0.7 V (typ), ESD protection >2 kV HBM, and fast switching with 3 ns turn-on delay and 5 ns fall time.

Technical Context

This P-channel MOSFET uses Trench technology to achieve low on-resistance and fast switching performance in a leadless 1.0 mm × 0.6 mm footprint. Its gate threshold voltage range (-0.45 V to -0.95 V) enables reliable turn-on from low-voltage logic rails, while the source-drain diode supports bidirectional current handling in load-switch configurations.

The device operates across -55 °C to 150 °C junction temperature and features normalized power derating down to zero at 175 °C ambient. Thermal resistance from junction to solder point is 65 K/W, enabling efficient heat transfer through the exposed drain pad on FR4 PCBs with 1 cm² copper area.

FAQ

What is the maximum continuous drain current for PMZB1200UPE at 100 °C ambient temperature?

The PMZB1200UPE supports -260 mA continuous drain current at T_amb = 100 °C, as specified in Table 5 (Limiting values). This derating reflects thermal constraints of the DFN1006B-3 package on standard FR4 PCBs and ensures safe operation without exceeding 150 °C junction temperature. The PMZB1200UPE maintains functionality across the full -55 °C to 150 °C junction range.

Does PMZB1200UPE require a gate pull-up resistor in high-side switch configurations?

No, the PMZB1200UPE does not require an external gate pull-up resistor in high-side configurations because it is a P-channel MOSFET that turns ON when the gate is pulled low relative to the source. In typical use, the gate is driven actively by a microcontroller GPIO or logic buffer; leaving it floating would result in undefined state. The PMZB1200UPE's low V_GS(th) ensures reliable turn-on even with weak drive sources.

Can PMZB1200UPE be used in automotive applications?

The PMZB1200UPE is not automotive-qualified per Nexperia's legal disclaimers. It is specified for industrial and consumer use only and has not undergone AEC-Q101 stress testing or PPAP validation. For automotive applications, designers must select explicitly qualified alternatives - the PMZB1200UPE should not be deployed in safety-critical or life-support systems, nor in environments requiring automotive-grade reliability and traceability.

What is the thermal resistance from junction to solder point (R_th(j-sp)) for PMZB1200UPE?

The PMZB1200UPE has a junction-to-solder-point thermal resistance of 65 K/W (typical), as stated in Table 6. This value assumes mounting on an FR4 PCB with single-sided copper, tin-plated finish, and a 1 cm² drain pad. It enables accurate thermal modeling for power dissipation up to 400 mW at 25 °C ambient, and supports reliable operation under pulsed loads via transient impedance curves in Figures 5 and 6.

How is the marking code structured on PMZB1200UPE packages?

The PMZB1200UPE uses a binary marking code "0101" followed by "0110" on the top surface of the DFN1006B-3 package, as shown in Figure 1. The first four bits identify the type number; orientation is indicated by a reading direction arrow adjacent to the marking. This two-line binary code is laser-etched and conforms to Nexperia's standard SOT883B marking scheme - no alphanumeric characters or date codes are present on the device itself.
