Product details
Overview
PMEG2020EH-QX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 20 V reverse voltage and 2 A forward current, featuring a typical forward voltage of 450 mV at 2 A and packaged in SOD123F for automotive-grade low-voltage rectification in DC-DC converters.
For engineers reviewing the PMEG2020EH-QX datasheet, PMEG2020EH-QX pinout, PMEG2020EH-QX application, or PMEG2020EH-QX equivalent, key selection criteria include its AEC-Q101 qualification, ultra-low VF performance at high current, thermal resistance to solder point (150 K/W), and SOD123F footprint compatibility with space-constrained automotive power rails.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to enhance ruggedness against electrical overstress and transient voltage spikes. Its low forward voltage stems from optimized metal-semiconductor junction design, enabling high conduction efficiency without compromising reverse leakage.
Thermal performance is defined by two distinct mounting conditions: Rth(j-a) = 330 K/W on standard FR4 and Rth(j-sp) = 150 K/W with extended cathode pad, directly supporting thermal management in compact automotive modules where solder-point cooling dominates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum continuous blocking voltage before breakdown; defines usable input range in 12 V automotive systems. |
| Forward Current (IF) | 2 A - Continuous DC current rating at Tsp ≤ 55 °C; supports sustained load in auxiliary power rails. |
| Forward Voltage (VF) | 450 mV typ. at 2 A - Enables <1 W conduction loss per diode in 2 A paths, critical for >95 % DC-DC efficiency. |
| Reverse Leakage (IR) | 45 µA max. at 20 V, 25 °C - Low leakage preserves battery standby life in always-on vehicle modules. |
| Diode Capacitance (Cd) | 50–60 pF at 5 V - Minimizes switching node ringing and EMI in high-frequency SMPS designs up to 2 MHz. |
| Junction Temperature (Tj) | 150 °C max - Allows operation in under-hood environments with ambient up to 125 °C when properly heatsinked. |
Pinout & Package
Encapsulated in the SOD123F surface-mount plastic package (2.6 mm × 1.6 mm × 1.1 mm body), this device features gull-wing leads optimized for reflow soldering on FR4 PCBs with standardized 2.9 mm × 1.6 mm land pattern.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Primary current exit terminal; connects to output rail or ground return; requires ≥1 cm² copper pad for optimal thermal dissipation. |
| 2 (A) | Anode | Current entry terminal; connects to input source or switching node; lower thermal mass than cathode pad. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS power supplies per discrete semiconductor stress test standard. |
| Guard ring integration | Improves surge robustness against ISO 7637-2 pulses and ESD events without external clamping components. |
| Ultra-low VF at 2 A | Reduces conduction losses by ~30 % versus comparable 20 V Schottkys, directly lowering thermal load in sealed enclosures. |
| SOD123F footprint | Enables board area reduction vs. SOD123 while maintaining compatibility with existing pick-and-place and reflow processes. |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Adapter |
|---|---|
Use Scenario: Reverse polarity protection on 12 V supply input to microcontroller-based lighting and door lock controllers. IC Role / Device Role: Unidirectional current gate preventing damage during battery jump-start misconnection.

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 NSS20201MZ4T1G | Same 20 V/2 A rating but higher VF (550 mV typ. at 2 A); SOD-123 package (not SOD123F). | Lacks AEC-Q101 qualification; not recommended for automotive production. | Select only for cost-sensitive industrial prototypes where qualification is not required. |
| Vishay VS-2EY20HM3/85A | Higher 200 V rating; larger SMC package; VF = 520 mV at 2 A; no guard ring. | Over-specified voltage rating increases board area and parasitic inductance in 12 V systems. | Use only if system requires >100 V transient tolerance and board space permits larger footprint. |
Compared with NSS20201MZ4T1G and VS-2EY20HM3/85A, PMEG2020EH-QX delivers the lowest conduction loss in automotive-qualified SOD123F form factor, with guard ring-enabled reliability that eliminates secondary protection components in 12 V power domains.

FAQ
What is the maximum allowable soldering temperature profile for PMEG2020EH-QX?
The device complies with JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles with peak temperature ≤ 260 °C for ≤ 30 seconds. The SOD123F package outline specifies 0.70 mm max lead thickness and 1.2 mm pad width, requiring controlled thermal ramp rates to avoid delamination.
Does PMEG2020EH-QX support bidirectional current flow?
No - it is a unidirectional Schottky rectifier with fixed anode (Pin 2) and cathode (Pin 1) polarity. Reverse conduction is blocked above 20 V, and intentional reverse bias beyond absolute maximum ratings causes permanent junction damage. It must be oriented correctly in series with the intended current path.
How does the guard ring affect layout requirements?
Layout must maintain ≥0.25 mm clearance between cathode pad edge and adjacent traces or planes to preserve guard ring effectiveness. The cathode pad should be isolated from other nets except its designated return path, and no vias should penetrate within 0.5 mm of the die attach region per Nexperia's SOD123F mechanical drawing.
Can PMEG2020EH-QX replace a standard PN junction diode in an existing design?
Yes - it can directly substitute 20 V/2 A PN diodes (e.g., 1N4001 variants) in low-voltage applications, reducing forward drop by ~400 mV and improving efficiency. However, reverse leakage will increase ~10×, so verify standby current budgets and ensure no sensitive analog references share the same return path.
