Product details
Overview
PMEG3020EJ-QX from Nexperia is a 30 V, 2 A ultra-low forward voltage Schottky barrier rectifier in SOD323F (SC-90) package, featuring integrated guard ring for stress protection and AEC-Q101 qualification. It delivers 510–620 mV VF at 2 A, supports reverse polarity protection and high-efficiency DC-DC conversion, and operates up to 150 °C junction temperature.
For engineers reviewing the PMEG3020EJ-QX datasheet, PMEG3020EJ-QX pinout, PMEG3020EJ-QX application, or PMEG3020EJ-QX equivalent, key selection criteria include ultra-low VF performance at 2 A, automotive-grade reliability per AEC-Q101, thermal resistance (Rth(j-sp) = 55 K/W), and SC-90 footprint compatibility with space-constrained PCB layouts.
Technical Context
This planar Schottky diode uses a guard-ring structure to enhance ruggedness against transient overvoltage and electrostatic stress, critical for automotive power rail protection. Its low VF minimizes conduction loss in low-voltage, high-current paths such as 3.3 V or 5 V DC-DC outputs.
The device exhibits low capacitance (60–72 pF at 1 V), enabling fast switching in SMPS freewheeling and reverse-battery protection circuits. Thermal design leverages low Rth(j-sp) of 55 K/W when mounted on a 1 cm² cathode pad, supporting sustained 2 A operation under ambient temperatures up to 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 510–620 mV at 2 A, pulsed - enables <1.24 W conduction loss in 5 V/2 A rails |
| Reverse Voltage (VR) | 30 V max - suitable for 24 V automotive systems with margin for load dump transients |
| Forward Current (IF) | 2 A continuous (Tsp ≤ 55 °C) - supports compact power stage designs without heatsinking |
| Reverse Current (IR) | ≤1000 µA at 30 V, 25 °C - ensures low leakage in battery-backed circuits |
| Diode Capacitance (Cd) | 60–72 pF at 1 V, 1 MHz - minimizes switching noise and EMI in >1 MHz SMPS |
| Junction Temperature (Tj) | −65 to +150 °C - enables operation in under-hood automotive environments |
| Thermal Resistance (Rth(j-sp)) | 55 K/W - allows 2 A DC current with <110 °C rise above solder point on 1 cm² pad |
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 cathode-marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output terminal for forward conduction; marked by bar on top surface; connects to load ground or return path |
| 2 | Anode (A) | Input terminal for forward conduction; connects to input rail or battery positive in reverse polarity protection |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 510–620 mV @ 2 A reduces power loss by ≥35% vs. standard Schottkys in 5 V rails |
| AEC-Q101 qualified | Stress-tested for automotive use - supports functional safety requirements in ASIL-B systems |
| Integrated guard ring | Improves surge immunity (IFSM = 9 A, 8 ms) and ESD robustness (HBM > 2 kV) |
| Small SOD323F footprint | 1.7 × 1.25 mm area saves >60% board space vs. SOD123 in portable and ADAS modules |

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 NSS30201MZ4T1G | VF = 550–650 mV @ 2 A; VR = 30 V; same SOD323F package; no AEC-Q101 qualification | Lacks automotive stress qualification; suitable for industrial/commercial only | Select when AEC-Q101 is not required and cost sensitivity outweighs qualification needs |
| Vishay SS23-M3/84A | VF = 500 mV @ 2 A; VR = 30 V; SOD-123 package (2.8 × 1.7 mm); higher Rth(j-a) = 200 K/W | Requires larger PCB area and additional thermal relief; less suited for dense automotive modules | Prefer when legacy SOD-123 layout reuse is mandatory and thermal margin exceeds 50 °C |
Compared with NSS30201MZ4T1G and SS23-M3/84A, PMEG3020EJ-QX uniquely combines AEC-Q101 compliance, ultra-low VF, and minimal SOD323F footprint-making it optimal for next-gen automotive ECUs where space, thermal density, and qualification are jointly constrained.

FAQ
Is PMEG3020EJ-QX suitable for 24 V automotive systems?
Yes. With a 30 V maximum reverse voltage rating and AEC-Q101 qualification, PMEG3020EJ-QX supports 24 V nominal systems including load dump transients up to ±30 V. Its 150 °C junction rating and guard ring ensure robustness in under-hood environments.
What is the thermal performance difference between Rth(j-a) and Rth(j-sp)?
Rth(j-a) is 350 K/W in free air (no PCB), while Rth(j-sp) is 55 K/W with a 1 cm² cathode copper pad. The latter reflects real-world PCB-mounted performance and enables 2 A continuous operation with <110 °C temperature rise above solder point.
Does the marking 'E9' correspond to PMEG3020EJ-QX?
Yes. Per Nexperia's marking code table, 'E9' is the unique top-side marking for PMEG3020EJ-QX in SOD323F package. The bar adjacent to pin 1 indicates the cathode terminal.
Can PMEG3020EJ-QX replace standard silicon diodes in 5 V SMPS designs?
Yes - its 510–620 mV VF at 2 A reduces conduction loss by ~65% versus a typical 1N5819 (VF ≈ 1.7 V). Combined with 72 pF capacitance and fast recovery, it improves efficiency and EMI in 5 V/1–2 A buck converters without redesigning gate drive timing.
