Nexperia USA Inc. PMEG10010ELXE-QX

Overview

PMEG10010ELXE-QX from Nexperia is a 100 V, 1 A planar Schottky barrier rectifier in CFP3-HP (SOD123HP) package, designed for high-efficiency DC-to-DC conversion and automotive-grade freewheeling. It delivers 720–780 mV forward voltage at 1 A/25 °C, <150 nA reverse leakage at 100 V/25 °C, and supports 50 A non-repetitive surge current - enabling robust operation in SMPS and reverse polarity protection circuits.

For engineers reviewing the PMEG10010ELXE-QX datasheet, PMEG10010ELXE-QX pinout, PMEG10010ELXE-QX application, or PMEG10010ELXE-QX equivalent, key selection criteria include low-leakage performance at 125 °C, AEC-Q101 qualification, thermal resistance to solder point (6 K/W), and clip-bond package-enhanced power capability - all critical for automotive power rail integrity and thermal reliability.

Technical Context

This Schottky rectifier uses a planar metal-semiconductor junction optimized for low VF and ultra-low IR across -40 °C to 175 °C junction temperature range. Its CFP3-HP package integrates an exposed cathode heatsink tab with 1 cm² copper pad, achieving Rth(j-sp) = 6 K/W - directly supporting high ambient temperature operation in engine bay or ADAS power modules.

The device exhibits step-recovery trr ≤ 4 ns and ramp-recovery trr ≤ 14 ns, with Qrr ≤ 13 nC and VFRM ≤ 680 mV, making it suitable for high-frequency switching topologies where reverse recovery losses must be minimized. Its 100 V VR rating is derated to ~80 V at Tj = 150 °C per Fig. 12, requiring explicit thermal design validation.

FAQ

Is PMEG10010ELXE-QX suitable for 48 V automotive battery systems?

Yes - its 100 V reverse voltage rating exceeds ISO 16750-2 requirements for 48 V systems (max transient 70 V), and AEC-Q101 qualification covers extended temperature operation (-40 °C to +175 °C). The 50 A surge rating also accommodates load dump events when used with appropriate TVS clamping.

What is the minimum recommended copper area for the cathode pad?

Nexperia specifies a 1 cm² copper pad for the cathode tab to achieve the rated Rth(j-sp) = 6 K/W and support 1 A average current at Tsp ≤ 170 °C. Using less than 1 cm² increases thermal resistance and reduces safe operating current - refer to Fig. 9 for derating curves with smaller pads.

How does the CFP3-HP package differ from standard SOD123?

CFP3-HP adds an exposed cathode heatsink tab with enhanced thermal interface, reducing Rth(j-sp) to 6 K/W versus ~20–30 K/W for standard SOD123. It also uses clip bonding instead of wire bonding, increasing surge current capability and power handling without increasing footprint size.

Can PMEG10010ELXE-QX replace silicon PN diodes in existing designs?

Yes, provided reverse voltage and surge requirements are met - its 100 V VR and 50 A IFSM exceed most 1 A silicon rectifiers. However, Schottky's higher reverse leakage at elevated temperature must be verified in the target circuit's worst-case thermal environment, especially above 100 °C.
