NXP Semiconductors PMZB600UNEL315

Overview

PMZB600UNEL from Nexperia is a 20 V, N-channel Trench MOSFET in a leadless DFN1006B-3 (SOT883B) package, designed for low-side switching in space-constrained applications. It delivers R_DS(on) = 470 mΩ at V_GS = 4.5 V and I_D = 0.6 A, supports ±8 V gate drive, and features ESD protection >1 kV HBM - enabling use in relay drivers and high-speed line drivers.

For engineers reviewing the PMZB600UNEL datasheet, PMZB600UNEL pinout, PMZB600UNEL application, or PMZB600UNEL equivalent, key selection criteria include its ultra-small 1.0 × 0.6 × 0.37 mm footprint, guaranteed R_DS(on) at 1.8 V gate drive, thermal resistance R_th(j-sp) = 40 K/W, and suitability for FR4 PCBs with standard or enhanced drain pad layouts.

Technical Context

This N-channel enhancement-mode MOSFET uses Trench technology to achieve low on-resistance in a sub-millimeter package. Its gate threshold voltage (V_GS(th)) ranges from 0.45 V to 0.95 V, enabling operation with logic-level gate drives down to 1.2 V, while maintaining low leakage (I_DSS ≤ 1 µA at 20 V, 25 °C).

The device exhibits fast switching performance: t_d(on) = 5.6 ns, t_r = 9.2 ns, Q_G(tot) = 0.7 nC, and C_iss = 21.3 pF. Its safe operating area supports peak drain current I_DM = 2.5 A (10 µs pulse), and normalized R_DS(on) increases only ~2.2× from 25 °C to 150 °C junction temperature.

Key Specifications

FAQ

What is the maximum continuous drain current rating for PMZB600UNEL at 100 °C ambient temperature?

The PMZB600UNEL supports a continuous drain current of 0.4 A 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 and ensures reliable operation without exceeding the 150 °C maximum junction temperature. At 25 °C ambient, the rating rises to 0.6 A under identical test conditions.

Does PMZB600UNEL support gate drive voltages below 2.5 V, and what is its R_DS(on) at 1.8 V?

Yes, PMZB600UNEL is characterized down to 1.2 V gate drive. At V_GS = 1.8 V and I_D = 0.1 A, R_DS(on) is 845 mΩ typical (Table 7), confirming functional operation with 1.8 V logic families. This enables direct interfacing with low-voltage MCUs without level shifters, though conduction loss increases relative to 4.5 V operation.

What is the thermal resistance from junction to solder point (R_th(j-sp)) for PMZB600UNEL, and how does it impact PCB layout?

The PMZB600UNEL has R_th(j-sp) = 40 K/W, measured from junction to the solder point on the drain pad. This low value indicates highly efficient thermal transfer through the drain terminal to PCB copper. To realize this performance, the layout must use the recommended 1 cm² drain pad on single-sided FR4 with tin plating - smaller pads degrade thermal performance significantly.

Can PMZB600UNEL be used in automotive applications?

No, PMZB600UNEL is not automotive-qualified. The datasheet explicitly states in Section 14 that "Unless this data sheet expressly states that this specific Nexperia product is automotive qualified, the product is not suitable for automotive use." It is rated for industrial and consumer temperature ranges (−55 °C to 150 °C junction), but lacks AEC-Q101 qualification, stress testing, or automotive-specific reliability data.

What is the gate leakage current (I_GSS) specification for PMZB600UNEL at room temperature?

At T_j = 25 °C, PMZB600UNEL specifies |I_GSS| ≤ 10 µA for both positive and negative gate bias (±8 V, ±4.5 V, and ±1.8 V), as shown in Table 7. This low leakage ensures minimal gate drive current demand and stable biasing in high-impedance control circuits, supporting long-duration static switching states without drift.
