Product details
Overview
PMEG4010EJ-QX from Nexperia is a 40 V, 1 A planar Schottky barrier rectifier with integrated guard ring for stress protection, housed in an SOD323F (SC-90) surface-mount package. It delivers very low forward voltage (540–640 mV at 1 A), low reverse leakage (≤100 µA at 40 V), and is AEC-Q101 qualified for automotive-grade reliability in low-voltage DC/DC conversion and reverse polarity protection circuits.
For engineers reviewing the PMEG4010EJ-QX datasheet, PMEG4010EJ-QX pinout, PMEG4010EJ-QX application, or PMEG4010EJ-QX equivalent, key selection criteria include its ultra-low VF performance at 1 A, thermal resistance to solder point (150 K/W), junction temperature rating (150 °C), and SC-90 footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky rectifier uses a planar die structure with an integrated guard ring to suppress edge breakdown and improve ruggedness under transient stress. Its low barrier height enables VF as low as 540 mV at 1 A and 25 °C, while maintaining IR ≤100 µA at VR = 40 V.
Designed for reflow-solder-only assembly on FR4 PCBs, it exhibits Rth(j-sp) = 150 K/W with a 1 cm² cathode pad and supports repetitive peak forward current up to 7 A (tp ≤ 1 ms). Thermal runaway mitigation is required due to significant reverse power loss contribution at elevated temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 540–640 mV at IF = 1 A - enables >92 % efficiency in 3.3 V–12 V DC/DC output stages |
| Reverse Voltage (VR) | 40 V maximum - supports 24 V automotive rail clamping and 36 V nominal input systems |
| Reverse Leakage (IR) | ≤100 µA at VR = 40 V - minimizes standby power loss in battery-backed circuits |
| Junction Temperature (Tj) | 150 °C max - allows operation in under-hood automotive environments without derating |
| Thermal Resistance (Rth(j-sp)) | 150 K/W - defines temperature rise from junction to cathode solder point on standard FR4 layout |
| Diode Capacitance (Cd) | 43–50 pF at VR = 1 V - limits switching noise and EMI in high-frequency SMPS designs |
| Peak Forward Surge (IFSM) | 9 A (8 ms square wave) - withstands cold-start inrush and load-dump transients |
Pinout & Package
Encapsulated in the SOD323F (SC-90) plastic SMD package: 1.7 mm × 1.25 mm × 0.7 mm body, 2-lead, single-sided copper FR4 mounting, reflow-solder only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Primary current sink terminal; connects to output rail or ground return path; requires ≥1 cm² copper pad for thermal management |
| 2 | Anode (A) | Input-side terminal; accepts positive supply or switched node; polarity-sensitive for reverse polarity protection |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge breakdown during voltage transients, improving long-term reliability in automotive load-dump conditions |
| AEC-Q101 qualification | Validated for automotive use per stress test requirements including HTGB, HTRB, and TCT, enabling drop-in deployment in Tier-1 modules |
| Ultra-low VF at 1 A | Reduces conduction loss by ≥35 % vs. standard Schottky diodes in 5 V–12 V buck converter freewheel paths |
| Low Cd (43–50 pF) | Minimizes capacitive coupling and ringing in >500 kHz switching converters, easing EMI filter design |
| Reflow-only assembly | Eliminates risk of thermal damage during hand-soldering; ensures consistent joint integrity on fine-pitch SMT lines |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30 | Higher VF (700 mV typ. @ 1 A), same VR (40 V), larger SOD-123 package (3.5 mm × 1.6 mm) | Less suitable for space-constrained automotive modules; higher conduction loss reduces efficiency in thermally limited enclosures | Select when board real estate permits larger footprint and lower cost is prioritized over thermal performance |
| SS12 | Lower VR (20 V), same IF (1 A), VF = 550 mV typ., DO-214AC package (4.3 mm × 2.6 mm) | Not rated for 24 V automotive systems; unsuitable for reverse polarity protection on 12 V/24 V buses | Acceptable only in consumer-grade 5 V–12 V adapters where VR margin and AEC-Q101 compliance are not required |
Compared with RB050M-30 and SS12, PMEG4010EJ-QX offers superior thermal performance (150 K/W Rth(j-sp)), AEC-Q101 qualification, and smallest footprint-making it optimal for automotive and space-constrained industrial power rails where efficiency, reliability, and size are jointly critical.

FAQ
Is PMEG4010EJ-QX compatible with lead-free reflow soldering profiles?
Yes. The device is qualified exclusively for reflow soldering per J-STD-020, with peak temperature up to 260 °C. Hand soldering is not recommended due to thermal stress risks on the small SC-90 package. The datasheet specifies reflow as the only approved method, and the thermal profile must maintain time above liquidus within 60–90 seconds.
What is the maximum continuous forward current at 85 °C ambient?
At Tamb = 85 °C, the maximum continuous forward current is derated to approximately 0.7 A based on thermal resistance (Rth(j-a) = 350 K/W) and Tj(max) = 150 °C. This assumes standard FR4 PCB with single-sided copper and tin-plated traces per datasheet condition [1]. Derating curves are provided in Figure 1 of the official datasheet.
Does PMEG4010EJ-QX require external thermal vias for operation at 1 A?
No external thermal vias are required, but a minimum 1 cm² copper pad on the cathode side is mandatory to achieve the specified Rth(j-sp) = 150 K/W. The datasheet explicitly defines thermal performance using this pad area on FR4; reducing pad size increases junction temperature and may violate Tj(max) at full load.
Can PMEG4010EJ-QX be used in reverse-biased Zener-like clamp configurations?
No. As a Schottky rectifier, it lacks controlled reverse breakdown characteristics. Its reverse breakdown voltage is not specified, and operation near or beyond VR = 40 V risks irreversible avalanche damage. It must be used strictly as a unidirectional rectifier or polarity protection device-not as a voltage clamp or TVS substitute.
