Product details
Overview
PMEG2010AEJ-QX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 20 V reverse voltage and 1 A forward current, featuring 480–550 mV forward voltage at 1 A, qualified to AEC-Q101 for automotive use in low-voltage DC/DC converters and polarity protection circuits.
For engineers reviewing the PMEG2010AEJ-QX datasheet, PMEG2010AEJ-QX pinout, PMEG2010AEJ-QX application, or PMEG2010AEJ-QX equivalent, key selection criteria include ultra-low VF performance, SOD323F package thermal resistance (Rth(j-sp) = 150 K/W), AEC-Q101 qualification, and 70 µA max reverse leakage at 20 V.
Technical Context
This Schottky diode employs a planar die structure with an integrated guard ring to enhance ruggedness against electrical overstress and transient voltage spikes. Its low-barrier metal-semiconductor junction enables fast switching (no minority-carrier storage) and minimal reverse recovery charge.
The device operates with junction temperatures up to 150 °C and is optimized for high-efficiency, space-constrained applications where thermal management relies on solder-point conduction (Rth(j-sp) = 150 K/W) rather than ambient convection (Rth(j-a) = 350 K/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum blocking capability without breakdown; defines usable input range in 12 V automotive systems. |
| Forward Current (IF) | 1 A continuous - Sustained conduction rating at ≤55 °C solder point temperature; supports compact power rail designs. |
| Forward Voltage (VF) | 480–550 mV @ 1 A - Directly reduces conduction loss and heat generation in high-current, low-VF paths. |
| Reverse Leakage (IR) | 15–70 µA @ 20 V - Low leakage preserves efficiency in standby and light-load conditions. |
| Diode Capacitance (Cd) | 40–50 pF @ 1 V - Enables fast switching with minimal capacitive loading in high-frequency SMPS feedback or sync rectifier nodes. |
| Thermal Resistance (Rth(j-sp)) | 150 K/W - Quantifies junction-to-solder-point thermal path; critical for PCB copper pad sizing in automotive under-hood layouts. |
| Junction Temperature (Tj) | 150 °C max - Specifies maximum allowable silicon operating temperature under sustained stress. |
Pinout & Package
Encapsulated in SOD323F (SC-90), a 1.7 mm × 1.25 mm × 0.7 mm surface-mount plastic package with flat leads and exposed cathode pad for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Output terminal for forward conduction; connects to PCB thermal pad for heat extraction and low-inductance return path. |
| 2 (A) | Anode | Input terminal for forward bias; routed with minimal trace length to reduce parasitic inductance in high-dI/dt applications. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances ESD and surge robustness without increasing VF or footprint-critical for automotive transients per ISO 7637-2. |
| AEC-Q101 qualification | Validated for automotive under-hood environments including temperature cycling, humidity, and mechanical shock testing. |
| Ultra-low VF at 1 A | 480–550 mV enables >95% efficiency in 3.3 V/5 V synchronous rectification stages with minimal heatsinking. |
| SOD323F package | 0.7 mm profile and 1.25 mm width allow placement beneath connectors or near ICs in ultra-thin modules. |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery (PD) Input Protection |
|---|---|
Use Scenario: Reverse polarity protection on 12 V supply rail feeding microcontroller and CAN transceiver subsystems. IC Role / Device Role / Timing Role: Unidirectional blocking diode preventing damage during battery jump-start misconnection. Use Value: 20 V VR rating covers load-dump transients; 1 A IF sustains peak BCM inrush; 550 mV VF limits voltage drop below MCU brown-out threshold. | Use Scenario: Input-side polarity guard for USB-C PD sink circuit accepting 5–20 V inputs. IC Role / Device Role / Timing Role: Series protection element placed before buck controller to block reverse current during hot-plug events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30TR | Higher VF (550–650 mV @ 1 A); larger SOD-123 package (3.5 mm × 1.6 mm) | Less suitable for ultra-thin modules; higher thermal resistance (Rth(j-a) ≈ 400 K/W) | Select when board space permits larger footprint and lower cost is prioritized over VF and thermal performance. |
| SS12HE3/5BT | Same 20 V/1 A rating but no AEC-Q101 qualification; VF 500–600 mV; SMA package (4.5 mm × 2.7 mm) | Not validated for automotive temperature cycling or humidity testing; unsuitable for under-hood deployment. | Choose only for non-automotive consumer or industrial applications where qualification is not required. |
Compared with RB050M-30TR and SS12HE3/5BT, PMEG2010AEJ-QX delivers superior thermal performance via SOD323F's low Rth(j-sp), tighter VF distribution, and guaranteed AEC-Q101 compliance-making it the preferred choice for space-constrained, mission-critical automotive and industrial power rails.

FAQ
What is the maximum junction temperature and how does it affect PCB layout?
The PMEG2010AEJ-QX has a maximum junction temperature of 150 °C. To maintain safe operation, the PCB must provide adequate thermal conduction-specifically, a 1 cm² cathode pad (per datasheet condition [2]) is required to achieve Rth(j-sp) = 150 K/W. Smaller pads increase thermal resistance and risk premature thermal shutdown or degradation.
Is the SOD323F package compatible with standard reflow profiles?
Yes-the SOD323F package is qualified for lead-free reflow soldering per JEDEC J-STD-020. The recommended peak temperature is 260 °C for ≤30 seconds, with ramp rates ≤3 °C/s. Figure 5 in the datasheet provides the exact solder land pattern (0.6 mm × 0.5 mm pads, 0.8 mm pitch) for reliable joint formation.
How does the guard ring improve reliability in automotive applications?
The integrated guard ring mitigates edge breakdown under high electric field stress, significantly improving resistance to ESD (IEC 61000-4-2 Level 4), load dump transients (ISO 7637-2 Pulse 5a), and repetitive voltage surges. This structural feature is verified through AEC-Q101 stress tests including HBM, MM, and TLP.
What is the typical reverse leakage at 85 °C and 20 V?
At 85 °C and 20 V reverse bias, the typical reverse leakage current is approximately 35 µA-derived from Figure 2 of the datasheet, which shows IR ≈ 35 µA at Tamb = 85 °C and VR = 20 V. This value remains well within the 70 µA maximum limit specified at 25 °C, confirming stable performance across automotive temperature ranges.
