Nexperia USA Inc. PMEG4010AESBZ

Overview

PMEG4010AESBZ from Nexperia is a 40 V, 1 A low forward-voltage Schottky barrier rectifier in a DSN1006-2 (SOD993) ultra-small surface-mount package, featuring typical VF = 435 mV at 1 A and IR = 325 µA at 40 V. It integrates a guard ring for stress protection and targets high-efficiency DC-to-DC conversion and mobile LED backlighting where minimal conduction loss and ultra-thin profile (<270 µm height) are critical.

For engineers reviewing the PMEG4010AESBZ datasheet, PMEG4010AESBZ pinout, PMEG4010AESBZ application, or PMEG4010AESBZ equivalent, this device is selected for low-voltage rectification in space-constrained, thermally sensitive power stages requiring fast switching (trr = 3.1 ns), low thermal resistance (Rth(j-sp) = 15 K/W), and stable performance across −40 °C to 150 °C junction temperature.

Technical Context

This MEGA Schottky rectifier uses a planar silicon structure with integrated guard ring to suppress edge breakdown and improve reliability under repetitive surge stress. Its low VF stems from optimized metal-semiconductor interface and thin epitaxial layer, enabling high efficiency at IF = 1 A with minimal self-heating.

The DSN1006-2 package features solderable anode and cathode terminals on a 1.0 mm × 0.6 mm footprint, with thermal path optimized via direct die attachment to PCB copper pads. Transient thermal impedance data confirms suitability for pulsed operation up to IFRM = 4 A (tp ≤ 1 ms) and IFSM = 10 A (tp = 8 ms).

FAQ

What is the maximum allowable soldering temperature profile for PMEG4010AESBZ?

The DSN1006-2 package is qualified for standard lead-free reflow per JEDEC J-STD-020. Peak temperature must not exceed 260 °C for ≤ 30 seconds, with ramp-up rate ≤ 3 °C/s and ramp-down rate ≤ 6 °C/s. Recommended footprint uses 0.5 mm wide solder lands with 0.6 mm spacing per Figure 16 of the datasheet.

Does PMEG4010AESBZ require external thermal vias for reliable operation at 1 A continuous current?

No - the device achieves 1.78 W power dissipation on FR4 with 1 cm² copper pads per terminal (anode and cathode), per Table 5. Thermal vias are unnecessary unless ambient temperature exceeds 115 °C or PCB copper area is reduced below 0.5 cm² per pad.

Can PMEG4010AESBZ be used in reverse polarity protection circuits?

Yes - its 40 V VR and 325 µA IR at 40 V make it suitable for low-loss reverse polarity protection in 3.3 V–24 V systems. Forward drop remains below 450 mV at 500 mA, limiting voltage loss while providing robust blocking against accidental reverse connection.

How does the guard ring affect reliability during transient overvoltage events?

The integrated guard ring redistributes electric field at the silicon periphery, raising the effective breakdown voltage at edges by ≥15%. This prevents localized avalanche and metallization damage during repetitive 40 V-rated transients, extending operational lifetime in DC/DC converters subject to load dump or inductive kick.
