Product details
Overview
PMEG2010AEH-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 a typ. 380 mV forward voltage at 1 A (pulsed), housed in an AEC-Q101-qualified SOD123F package for automotive low-voltage rectification and reverse polarity protection.
For engineers reviewing the PMEG2010AEH-QX datasheet, PMEG2010AEH-QX pinout, PMEG2010AEH-QX application, or PMEG2010AEH-QX equivalent, key selection criteria include its ultra-low VF performance at 1 A, thermal resistance of 150 K/W to solder point, AEC-Q101 qualification, and SOD123F footprint compatibility with space-constrained DC/DC converters.
Technical Context
This Schottky diode employs a planar junction structure with an integrated guard ring to enhance robustness against electrical overstress and improve reliability under transient conditions. Its low forward voltage minimizes conduction losses in high-efficiency power conversion stages where thermal management is constrained.
The device operates with a maximum junction temperature of 150 °C and exhibits reverse leakage currents as low as 15 µA at 5 V (25 °C), supporting stable operation in low-power automotive subsystems such as body control modules and sensor interfaces requiring minimal standby loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Supports input rails up to 16 V nominal with 25 % margin for automotive transients. |
| Forward Current (IF) | 1 A continuous at Tsp ≤ 55 °C - Enables use in compact 5–12 V DC/DC outputs without forced cooling. |
| Forward Voltage (VF) | 380–430 mV at 1 A (pulsed) - Reduces conduction loss to < 430 mW, critical for >90 % efficiency targets. |
| Reverse Current (IR) | 50–200 µA at VR = 20 V (25 °C) - Limits standby power drain in always-on vehicle networks. |
| Diode Capacitance (Cd) | 55–70 pF at VR = 5 V, 1 MHz - Minimizes switching node ringing in high-frequency (>500 kHz) buck converters. |
| Thermal Resistance (Rth(j-sp)) | 150 K/W - Enables direct thermal coupling to PCB copper pour for passive heat dissipation in SMT layouts. |
Pinout & Package
Encapsulated in a surface-mounted SOD123F plastic package (2.6 mm × 1.6 mm × 1.1 mm body), with cathode and anode terminals exposed on opposite ends for standard reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to output/load side; carries return current and defines reference for reverse blocking. |
| 2 | Anode (A) | Connected to input/source side; accepts forward-biased current flow toward cathode during conduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS power rails. |
| Integrated guard ring | Improves ruggedness against ESD and voltage transients without external clamping components. |
| Ultra-low VF at 1 A | Reduces I²R losses by ~40 % versus standard Schottkys with VF > 600 mV in same package. |
| SOD123F footprint | Compatible with automated placement and reflow processes; occupies < 4.2 mm² board area. |
Applications
| Automotive Body Control Module | USB-C Power Delivery Input Stage |
|---|---|
Use Scenario: Reverse polarity protection for 12 V supply rail feeding microcontroller and CAN transceiver. IC Role / Device Role / Timing Role: Unidirectional current gate preventing damage during battery misconnection. Use Value: 380 mV VF ensures < 0.4 W loss at 1 A, eliminating need for heatsinking in sealed enclosures. |
Use Scenario: Low-loss OR-ing diode in dual-input (adapter + battery) USB PD power path. IC Role / Device Role / Timing Role: Forward-biased conduction selector enabling seamless source switchover. Use Value: 55 pF capacitance minimizes high-frequency noise injection into CC logic lines during switching. |
| Industrial IoT Sensor Node | Low-Power Buck Converter Output Rectifier |
Use Scenario: Input protection for 3.3 V LDO powered from harvested energy (e.g., solar + supercap). IC Role / Device Role / Timing Role: Prevents backfeed from storage capacitor into harvester during low-light conditions. Use Value: 15 µA IR at 5 V enables >10-year shelf life in battery-backed nodes with µA-level quiescent budgets. |
Use Scenario: Synchronous rectifier replacement in 1 MHz, 3.3 V/500 mA buck converter for wearables. IC Role / Device Role / Timing Role: Freewheeling path during high-side FET off-time, defining minimum on-time limit. Use Value: 150 K/W Rth(j-sp) allows full 1 A rating with only 1 cm² cathode copper pad-no thermal vias required. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB055LAM-40TR | Higher VF (450 mV typ. @ 1 A), same 20 V VR, SOD-123 package but no AEC-Q101 qualification. | Acceptable for industrial consumer power supplies; not approved for automotive ECUs. | Select when AEC-Q101 is not mandated and 70 mV higher VF is tolerable in thermal budget. |
| SS12HE3/5BT | Lower IF rating (200 mA), higher VR (25 V), VF = 500 mV @ 200 mA, SMA package (larger footprint). | Suitable for low-current signal-line protection; cannot replace PMEG2010AEH-QX in 1 A DC/DC outputs. | Choose only for cost-sensitive, non-automotive designs with < 250 mA load and ≥25 V transient margin. |
Compared with RB055LAM-40TR and SS12HE3/5BT, PMEG2010AEH-QX uniquely delivers automotive-grade reliability, lowest VF at full 1 A rating, and smallest footprint-making it optimal for space- and efficiency-critical automotive power rails.

FAQ
What is the maximum allowable junction temperature for PMEG2010AEH-QX?
The absolute maximum junction temperature is 150 °C, validated per IEC 60134 limiting values. Operation above this threshold risks permanent degradation of the Schottky barrier. Derating is required above ambient temperatures exceeding 55 °C to maintain safe Tj under 1 A continuous load.
Does PMEG2010AEH-QX support reflow soldering per JEDEC J-STD-020?
Yes-it is qualified for standard lead-free reflow profiles (peak 260 °C, 30 s max), with recommended footprint dimensions published in Figure 6 of the datasheet (2.8 mm × 1.6 mm solder land, 1.1 mm pad extensions). Thermal relief design must respect the 150 K/W Rth(j-sp) path to cathode pad.
How does the integrated guard ring affect layout requirements?
The guard ring enhances ESD and transient immunity without altering PCB layout-no additional clearance or guard traces are needed. However, maintaining minimum 0.25 mm solder mask opening around the cathode pad ensures full thermal benefit from the specified Rth(j-sp) value.
Is PMEG2010AEH-QX suitable for synchronous rectification in DC/DC converters?
No-it is a unidirectional Schottky rectifier, not a synchronous MOSFET driver or controlled switch. It functions as a passive freewheeling diode; synchronous rectification requires active gate-controlled MOSFETs with timing circuitry. Its low VF and low Cd make it ideal as a high-efficiency asynchronous alternative.
