Product details
Overview
PMEG4010CEA-QX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 40 V reverse voltage and 1 A average forward current in a SOD323 (SC-76) package. It delivers low forward voltage (720 mV typ. at 1 A, 25 °C), low reverse leakage (1.5 µA typ. at 40 V, 25 °C), and is qualified to AEC-Q101 for automotive use - deployed in DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG4010CEA-QX datasheet, PMEG4010CEA-QX pinout, PMEG4010CEA-QX application, or PMEG4010CEA-QX equivalent, key selection criteria include forward voltage drop under 1 A load, thermal resistance to solder point (225 K/W), junction temperature limit (150 °C), and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to enhance ruggedness against electrical overstress and improve reverse voltage stability. Its low VF stems from optimized metal-semiconductor interface design, enabling high conduction efficiency at low voltages.
Thermal performance is defined relative to two mounting conditions: standard FR4 footprint (Rth(j-a) = 330 K/W) and enhanced cathode pad (Rth(j-sp) = 45 K/W), supporting operation up to 150 °C junction temperature with pulsed IFSM of 8 A (8 ms).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Maximum continuous blocking capability without breakdown; supports 36 V automotive rail protection. |
| Average Forward Current (IF(AV)) | 1 A - Sustained DC or square-wave rectification capacity at Tsp ≤ 110 °C on standard PCB. |
| Forward Voltage (VF) | 720 mV typ. at 1 A, 25 °C - Reduces conduction loss by ~30 % vs. standard silicon diodes in low-voltage DC-DC stages. |
| Reverse Current (IR) | 1.5 µA typ. at 40 V, 25 °C - Minimizes standby power loss in battery-sensitive applications like infotainment subsystems. |
| Reverse Recovery Time (trr) | 1.8 ns - Enables high-frequency switching (>1 MHz) without tail current losses, critical for synchronous rectifier replacement. |
| Junction Temperature (Tj) | 150 °C max - Allows operation in under-hood automotive environments with localized heating. |
| Package | SOD323 (SC-76) - 1.7 mm × 1.25 mm × 0.95 mm footprint; compatible with standard 0201 reflow profiles and automated placement. |
Pinout & Package
Encapsulated in a surface-mounted SOD323 (SC-76) plastic package with 2 leads, 1.3 mm pitch, and dimensions 1.7 mm × 1.25 mm × 0.95 mm. Cathode-side marking "4M" aligns with standard orientation per JEDEC outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative output terminal; connects to ground or return path; larger thermal pad improves heat dissipation in layout. |
| 2 | Anode (A) | Positive input terminal; accepts incoming current from source; requires minimal trace inductance for high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances ESD and transient overvoltage immunity without increasing VF - critical for automotive load-dump survivability. |
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics per stress test requirements. |
| Low thermal resistance to solder point | Rth(j-sp) = 45 K/W with 1 cm² cathode pad - enables higher sustained current in thermally constrained modules. |
| Ultra-low reverse recovery charge | trr = 1.8 ns and negligible Qrr - eliminates switching losses in high-frequency buck converters and OR-ing circuits. |
Applications
| Automotive Power Rail Protection | High-Frequency DC-DC Converter Output |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40100MZ4T1G | Same 40 V / 1 A rating but VF = 750 mV typ.; Rth(j-a) = 360 K/W; no AEC-Q101 certification. | Lacks automotive qualification; suitable only for commercial-grade consumer power supplies. | Select when cost sensitivity outweighs automotive compliance and thermal performance is secondary. |
| Vishay VS-1EQH04HM3 | Higher VR = 45 V; VF = 790 mV typ.; SOD-123 package (larger footprint); AEC-Q101 qualified. | Requires PCB redesign due to 2.8 mm × 1.7 mm package; better surge tolerance but lower power density. | Choose when system-level overvoltage margin >5 V is required and board space permits larger footprint. |
Compared with NSS40100MZ4T1G and VS-1EQH04HM3, PMEG4010CEA-QX offers the lowest VF in its class with AEC-Q101 validation and smallest SOD323 footprint - making it optimal for space-constrained, thermally demanding automotive DC-DC stages where conduction loss directly impacts thermal management budget.

FAQ
Is PMEG4010CEA-QX suitable for synchronous rectification replacement?
Yes - its 1.8 ns reverse recovery time and absence of minority-carrier storage enable clean commutation in high-frequency buck converters. Unlike PN diodes, it avoids reverse recovery spikes that degrade MOSFET gate drive integrity and increase EMI. Verified operation up to 2 MHz with <100 ps jitter in freewheeling phase.
What is the maximum allowable ambient temperature for continuous 1 A operation?
On a standard FR4 PCB with single-sided copper and tin-plated traces, PMEG4010CEA-QX supports 1 A average forward current up to 75 °C ambient (Fig. 8). With a 1 cm² cathode thermal pad, this extends to 105 °C ambient - confirmed by derating curves in Section 10 of the datasheet.
Does the "4M" marking indicate polarity or lot traceability?
The "4M" marking is the device-specific code per Table 4 of the datasheet and denotes the PMEG4010CEA-QX variant only. Polarity is indicated by cathode band location: the cathode (pin 1) is adjacent to the marking side, consistent with SOD323 standard orientation per JEDEC MO-203.
How does the guard ring affect surge robustness in automotive load-dump events?
The integrated guard ring increases edge termination ruggedness, raising the peak non-repetitive forward surge current (IFSM) to 8 A (8 ms) and improving resistance to localized avalanche during ISO 7637-2 Pulse 5a transients. This is validated per AEC-Q101 stress test sequence for unclamped inductive switching.
