Product details
Overview
PMEG4010EXE-QX from Nexperia is a 40 V, 1 A automotive-qualified Schottky barrier rectifier in CFP3-HP (SOD123HP) package, designed for low-voltage DC-to-DC conversion and reverse polarity protection. It delivers 430 mV typical forward voltage at 1 A and 25 °C, exhibits 10 µA max reverse leakage at 40 V/25 °C, and supports 50 A non-repetitive surge current - enabling high-efficiency power path management in space-constrained automotive ECUs.
For engineers reviewing the PMEG4010EXE-QX datasheet, PMEG4010EXE-QX pinout, PMEG4010EXE-QX application, or PMEG4010EXE-QX equivalent, key selection criteria include forward voltage vs. temperature behavior, thermal resistance to solder point (6 K/W), AEC-Q101 qualification status, and SOD123HP footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky rectifier uses a planar metal–semiconductor junction optimized for low VF and fast recovery, with no minority-carrier storage - eliminating reverse recovery charge (Qrr = 2.5 nC) and enabling operation up to 20 kHz square-wave switching. Its clip-bond construction enhances thermal conduction from junction to exposed cathode tab.
The device operates across –40 °C to +175 °C junction temperature range, maintains stable VF from –40 °C to +125 °C (330–570 mV at 1 A), and achieves 115 K/W Rth(j-sp) on FR4 with 1 cm² cathode pad - critical for thermal reliability in under-hood automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 40 V maximum reverse voltage - defines safe blocking capability in 24 V automotive systems with load-dump transients. |
| IF(AV) | 1 A average forward current at δ = 0.5, 20 kHz - supports continuous operation in high-frequency SMPS outputs. |
| VF @ 1 A, 25 °C | 430–490 mV - enables <1.5 W conduction loss at full load, reducing heatsink requirements. |
| IR @ 40 V, 125 °C | 6–25 mA - limits standby power loss in always-on vehicle networks. |
| Rth(j-sp) | 6 K/W - allows direct thermal coupling to PCB copper, enabling >1.3 W dissipation without external heatsink. |
| trr | 4 ns step recovery - eliminates switching node ringing in synchronous rectifier circuits. |
| AEC-Q101 | Qualified - meets stress test requirements for automotive discrete semiconductors including HTGB, HTRB, and ESD. |
Pinout & Package
Encapsulated in CFP3-HP (SOD123HP) surface-mount plastic package: 2.80 mm × 1.80 mm × 0.90 mm body with exposed cathode thermal pad; standard footprint per Figure 16 (Nexperia doc 23-11-29).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Main current sink terminal; marked with bar; connects to thermal pad for heat extraction and circuit ground reference. |
| 2 | Anode (A) | Current source terminal; routed to input rail or switch node; minimal parasitic inductance due to short internal bond. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high temperature | 330 mV typ. at 1 A/125 °C - maintains efficiency in engine bay environments where ambient exceeds 85 °C. |
| High surge robustness | 50 A IFSM (8.3 ms half-sine) - withstands cranking transients and inductive kickback without degradation. |
| Exposed thermal pad | 6 K/W Rth(j-sp) - enables >2× higher power handling than standard SOD-123 equivalents on identical PCB layout. |
| AEC-Q101 qualification | Qualified per stress test standard - eliminates need for customer requalification in automotive Tier-1 designs. |
| Low Qrr | 2.5 nC - reduces switching losses and EMI in high-frequency buck converters operating above 500 kHz. |
Applications
| Automotive Body Control Module | USB-C Power Delivery Input Stage |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-1EQH04-M3/86A | 45 V VR, 1 A IF(AV), SOD-123 package, Rth(j-a) = 190 K/W (no exposed pad) | Lacks AEC-Q101 qualification and thermal pad - unsuitable for under-hood use above 85 °C ambient | Select only for non-automotive, low-power consumer applications with ample airflow |
| ON Semiconductor NSR0140P2T5G | 40 V VR, 1 A IF(AV), SOD-123 package, VF = 450 mV typ., Rth(j-a) = 180 K/W | No AEC-Q101 qualification; lower surge rating (30 A IFSM); no thermal pad | Acceptable for cost-sensitive industrial DC/DC where AEC compliance is not required |
Compared with PMEG4010EXE-QX, both alternatives lack the clip-bond thermal architecture and automotive qualification - resulting in higher thermal resistance, reduced surge margin, and mandatory requalification for automotive deployment.

FAQ
Is PMEG4010EXE-QX pin-compatible with standard SOD-123 diodes?
Yes - it uses the CFP3-HP variant of SOD123HP, which shares identical PCB footprint dimensions (2.80 mm × 1.80 mm) and 2-pin anode/cathode layout with JEDEC-standard SOD-123. The exposed cathode pad requires no layout change but improves thermal performance over legacy SOD-123 parts.
What is the maximum allowable solder point temperature during reflow?
The device is rated for peak reflow temperature of 260 °C per J-STD-020, with 60-second maximum time above 217 °C. The recommended stencil thickness is 0.1 mm, and the cathode thermal pad must be fully soldered to achieve specified Rth(j-sp) = 6 K/W.
Does PMEG4010EXE-QX support bidirectional current flow?
No - it is a unidirectional Schottky rectifier. Current flows only from anode to cathode; reverse bias beyond 40 V risks permanent breakdown. It is not rated for reverse conduction or AC rectification duty.
How does its thermal performance compare to standard SOD-123 Schottky diodes?
With Rth(j-sp) = 6 K/W, PMEG4010EXE-QX delivers >3× better thermal coupling than typical SOD-123 parts (Rth(j-a) ≈ 190 K/W). On identical FR4 PCBs, it sustains 1.3 W dissipation versus ~0.4 W for conventional equivalents - verified per Nexperia Figure 9 data.
