Nexperia USA Inc. PMEG6002EB-QF

Overview

PMEG6002EB-QF from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 60 V reverse voltage and 0.2 A forward current, featuring a typical forward voltage of 540 mV at 200 mA and optimized for low-power automotive DC/DC conversion and reverse polarity protection in space-constrained SMD layouts.

For engineers reviewing the PMEG6002EB-QF datasheet, PMEG6002EB-QF pinout, PMEG6002EB-QF application, or PMEG6002EB-QF equivalent, key selection criteria include its AEC-Q101 qualification, ultra-low VF performance across temperature, SC-79 (SOD523) package footprint, and thermal resistance of 75 K/W to solder point - critical for thermally sensitive automotive body electronics and battery management subsystems.

Technical Context

This discrete Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown under high dv/dt or mechanical stress, enabling reliable operation in automotive transients. Its low junction capacitance (14–20 pF at 1 V) and fast recovery support high-frequency switching up to several MHz in buck converters.

The device operates with a maximum junction temperature of 150 °C and exhibits reverse leakage as low as 2 µA at 10 V and 25 °C, rising to 310 µA at 100 °C - a trade-off managed via thermal design due to its 400 K/W junction-to-ambient resistance in free air.

Manufacturer

Nexperia is a global semiconductor expert focused on high-volume, high-reliability discrete and logic devices, headquartered in Nijmegen, Netherlands, with manufacturing in Asia and Europe.

This device belongs to Nexperia's AEC-Q101-qualified Schottky rectifier portfolio, engineered specifically for automotive power rail protection and efficiency-critical low-current DC/DC stages where VF, size, and transient robustness are co-optimized.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Compared with NSSR0260HT1G and VS-2EDH02HM3/85A, PMEG6002EB-QF uniquely balances AEC-Q101 compliance, ultra-small SOD523 footprint, and sub-600 mV VF - making it the only choice for thermally constrained automotive modules where both qualification and size are non-negotiable.

FAQ

Is PMEG6002EB-QF suitable for reverse battery protection in 12 V automotive systems?

Yes. With 60 V VR rating and AEC-Q101 qualification, it withstands ISO 7637-2 load dump pulses up to ±100 V. Its 540 mV VF at 200 mA limits power dissipation to 108 mW, enabling use without heatsinking in sealed BCM housings. The guard ring ensures stable breakdown behavior during repeated polarity reversals.

What is the maximum allowable PCB copper area for thermal relief in free-air operation?

Per Nexperia's thermal characterization, the device achieves Rth(j-a) = 400 K/W on FR4 with single-sided 1 oz copper and standard SOD523 footprint. Adding 10 mm² of 1 oz copper connected directly to the cathode pad reduces Rth(j-a) by ~35%, but no additional thermal pads are required for ≤0.2 A continuous operation at Tamb ≤ 85 °C.

Does the marking 'B2' correspond to the full part number PMEG6002EB-QF?

Yes. Per Table 4 of the datasheet, 'B2' is the official top-side marking for PMEG6002EB-Q. The '-QF' suffix denotes tape-and-reel packaging per AEC-Q101 requirements, and is not marked on the device body - the marking remains 'B2' regardless of packaging variant.

Can PMEG6002EB-QF be used in place of a 1N5817 in a low-cost consumer power supply?

No. While both are Schottky rectifiers, the 1N5817 is rated for 1 A and 20 V, whereas PMEG6002EB-QF is limited to 0.2 A and 60 V. Substituting it in a 1N5817 application risks thermal runaway and premature failure due to insufficient current rating and different thermal mass - even if VF appears lower at low currents.
