Product details
Overview
PMEG2020EJ-QX from Nexperia is a 20 V, 2 A planar Schottky barrier rectifier with integrated guard ring for stress protection, housed in an ultra-compact SOD323F (SC-90) surface-mount package. It delivers a typ. 450 mV forward voltage at 2 A and 25 °C, enabling high-efficiency low-voltage rectification in space-constrained automotive power rails and DC-DC converters.
For engineers reviewing the PMEG2020EJ-QX datasheet, PMEG2020EJ-QX pinout, PMEG2020EJ-QX application, or PMEG2020EJ-QX equivalent, key selection criteria include its AEC-Q101 qualification, 525 mV max VF at 2 A, 20 V VR rating, 9 A non-repetitive peak forward current, and thermal resistance of 150 K/W junction-to-solder-point on standard FR4 PCB.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low VF stems from optimized metal-semiconductor interface design and thin epitaxial layer, minimizing conduction loss in continuous 2 A operation up to 150 °C junction temperature.
The device operates within strict automotive-grade thermal limits: Rth(j-sp) = 150 K/W enables stable performance when soldered to a 1 cm² cathode pad on FR4, while its 360 mW total power dissipation at 25 °C ambient supports compact layout without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 450–525 mV at 2 A, 25 °C - enables <1.05 W conduction loss in 5 V/2 A buck converter output stage |
| Reverse Voltage (VR) | 20 V - supports 12 V automotive systems with 67 % safety margin against load-dump transients |
| Forward Current (IF) | 2 A continuous - rated for sustained operation at Tsp ≤ 55 °C on standard PCB footprint |
| Reverse Current (IR) | 45–200 µA at 20 V, 25 °C - ensures minimal leakage in battery backup and polarity protection circuits |
| Diode Capacitance (Cd) | 50–60 pF at 5 V, 1 MHz - reduces switching noise and EMI in high-frequency SMPS designs |
| Junction Temperature (Tj) | −40 to +150 °C - validated for under-hood automotive environments per AEC-Q101 stress testing |
| Thermal Resistance (Rth(j-sp)) | 150 K/W - defines temperature rise from junction to cathode solder point on 1 cm² copper pad |
Pinout & Package
Encapsulated in the SC-90 (SOD323F) package: 1.7 mm × 1.25 mm × 0.7 mm body, flat lead profile optimized for automated reflow assembly and minimal board area usage.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to negative rail or ground return path; carries full forward current and anchors thermal path to PCB copper |
| 2 | Anode (A) | Input terminal for positive supply; reverse-biased during freewheeling to block backfeed in polarity protection |
Key Features
| Feature | Design Value |

| Guard ring integration | Suppresses edge avalanche and improves long-term reliability under repetitive voltage transients in automotive 12 V systems |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and ESD per JEDEC JESD22 standards |
| Ultra-low VF profile | 200 mV typ. at 10 mA enables efficient biasing in low-power sensor interfaces and always-on circuitry |
| SOD323F footprint compatibility | Standardized 0.5 mm pitch, 0.6 mm pad width - supports IPC-7351B compliant layout and high-yield reflow |
| Low capacitance (50–60 pF) | Minimizes switching losses and RF coupling in 500 kHz–2 MHz DC-DC controllers |
Applications

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 | 30 V VR, 0.5 A IF, DO-214AC package (larger, higher VF ≈ 550 mV @ 0.5 A) | Not AEC-Q101 qualified; suitable only for industrial/commercial non-automotive use | Select only if higher reverse voltage margin is required and space constraints allow larger footprint |
| SS22 | 20 V VR, 2 A IF, SMA package (3.5 mm × 1.6 mm), VF ≈ 500 mV @ 2 A, no AEC-Q101 certification | Lacks automotive qualification; thermal resistance ~200 K/W on same PCB - limits continuous 2 A use | Acceptable for cost-sensitive consumer DC-DC where AEC-Q101 is not mandated and thermal headroom exists |
Compared with RB050M-30 and SS22, PMEG2020EJ-QX provides the only combination of AEC-Q101 compliance, SOD323F miniaturization, and sub-500 mV VF at full 2 A rating - making it uniquely suited for space- and reliability-critical automotive power nodes.

FAQ
What is the maximum continuous forward current for PMEG2020EJ-QX under standard PCB conditions?
The PMEG2020EJ-QX is rated for 2 A continuous forward current when soldered to a standard FR4 PCB with single-sided 1 oz copper and ambient temperature ≤25 °C. Derating applies above 55 °C solder point temperature per datasheet limiting values table.
Does PMEG2020EJ-QX support reflow soldering, and what is the recommended profile?
Yes - PMEG2020EJ-QX is qualified for lead-free reflow per J-STD-020. The recommended profile uses peak temperature ≤260 °C for ≤30 seconds, with ramp-up rate ≤3 °C/s and cooling rate ≤6 °C/s, matching the SOD323F package outline and thermal mass.
How does the integrated guard ring affect reliability in automotive applications?
The guard ring mitigates electric field crowding at the die edge, raising the effective breakdown voltage and improving resistance to ESD and load-dump transients. This directly extends lifetime in automotive 12 V systems where repetitive 40 V transients occur per ISO 7637-2.
Can PMEG2020EJ-QX replace standard PN-junction diodes in existing 12 V rectifier designs?
Yes - its 20 V VR and 2 A IF match common 1N400x and 1N5819 footprints in function, but requires verifying layout clearance due to SOD323F's smaller size and lower thermal mass. Forward voltage reduction from ~700 mV to ~450 mV improves efficiency by ~35 % at 2 A.
