Product details
Overview
PMEG3020EGW-QX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 30 V reverse voltage and 2 A average forward current, featuring low 510 mV typical forward voltage and 400 µA typical reverse leakage at 30 V, used in automotive-grade DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG3020EGW-QX datasheet, PMEG3020EGW-QX pinout, PMEG3020EGW-QX application, or PMEG3020EGW-QX equivalent, key selection criteria include VF vs. IF trade-off at 25–150 °C, thermal resistance to solder point (190 K/W), AEC-Q101 qualification status, and SOD123 footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky diode employs a planar junction structure with an integrated guard ring to suppress edge breakdown under transient stress, enabling stable operation up to 150 °C junction temperature. Its low VF stems from optimized metal-semiconductor interface engineering rather than barrier height reduction alone.
The device delivers 2 A average forward current under square-wave excitation (δ = 0.5, f = 20 kHz) with solder-point temperature limited to 115 °C, and supports repetitive peak currents up to 4.5 A (tp ≤ 1 ms) and non-repetitive surges of 9 A (tp = 8 ms).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum continuous blocking voltage before breakdown; defines usable input range in 24 V automotive systems. |
| Average Forward Current (IF(AV)) | 2 A - Sustained DC or pulsed-current capability with Tsp ≤ 115 °C on FR4 PCB; enables compact 12–24 V converter outputs. |
| Forward Voltage (VF) | 510 mV typ. @ 2 A - Directly reduces conduction loss in high-frequency switching paths; improves efficiency by ~0.5–1.2% over 700 mV alternatives. |
| Reverse Leakage (IR) | 400 µA typ. @ 30 V - Low leakage preserves battery life in always-on automotive modules; validated under pulsed test to avoid self-heating artifacts. |
| Thermal Resistance (Rth(j-sp)) | 190 K/W - Junction-to-solder-point resistance measured on 1 cm² cathode pad; informs thermal design margin for 1.5 W dissipation at max ambient. |
| Diode Capacitance (Cd) | 60 pF typ. @ 1 V - Enables fast switching with minimal ringing in >1 MHz DC-DC topologies; lower than comparable 30 V Si diodes. |
| Junction Temperature (Tj) | 150 °C - Maximum allowable operating junction temperature; supports under-hood automotive environments without derating. |
Pinout & Package
Encapsulated in the compact SOD123 surface-mount plastic package (2.675 mm × 1.6 mm × 1.15 mm body), with cathode marked by a bar on the device top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative output terminal; connects to load ground or return path; marking bar identifies this pin; requires ≥1 cm² copper pad for thermal management. |
| 2 | Anode (A) | Positive input terminal; connects to switched node or supply rail; carries full forward current and must be routed with low-inductance trace. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Prevents premature edge breakdown during voltage transients, improving reliability in automotive load-dump and ISO 7637-2 pulse conditions. |
| AEC-Q101 qualification | Validated per Stress Test Qualification for Discrete Semiconductors; includes HTGB, HTRB, ESD-HBM ≥ 2 kV, and temperature cycling. |
| Low VF / low IR balance | 510 mV @ 2 A and 400 µA @ 30 V achieved without compromising surge robustness-enables high-efficiency, low-heat designs. |
| SOD123 footprint | Standardized 2.675 mm × 1.6 mm outline compatible with automated placement and reflow; supports <0.5 mm pitch routing in space-constrained ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-2EJH03-M3/54 | 30 V VR, 2 A IF(AV), VF = 540 mV @ 2 A, Rth(j-a) = 320 K/W (free air), no AEC-Q101 certification | Not qualified for automotive use; suitable only for industrial/commercial power supplies where qualification is not mandated | Select when cost sensitivity outweighs automotive compliance and thermal performance is less critical. |
| ON Semiconductor NSR20F30NXT5G | 30 V VR, 2 A IF(AV), VF = 490 mV @ 2 A, Rth(j-sp) = 170 K/W, AEC-Q101 qualified, SOD-123FL package (slightly longer leads) | Lower VF and better thermal resistance, but SOD-123FL footprint differs slightly-requires layout review for pad compatibility | Select when maximizing efficiency and thermal margin is priority, and board revision supports SOD-123FL land pattern. |
Compared with VS-2EJH03-M3/54, PMEG3020EGW-QX provides AEC-Q101 assurance and 190 K/W Rth(j-sp) for tighter thermal control; versus NSR20F30NXT5G, it trades 20 mV higher VF for identical footprint and broader distributor availability.

FAQ
Is PMEG3020EGW-QX suitable for 48 V automotive systems?
No. With a 30 V maximum reverse voltage rating, PMEG3020EGW-QX is designed for 12 V and 24 V nominal automotive systems. For 48 V architectures, a 60 V or higher VR Schottky rectifier such as PMEG6020EH is required to maintain adequate voltage margin against transients.
What is the meaning of the 'Q' suffix in PMEG3020EGW-QX?
The 'Q' suffix denotes AEC-Q101 qualification per the Automotive Electronics Council standard. The 'X' in PMEG3020EGW-QX is a Nexperia internal revision or packaging variant identifier-not a functional or specification difference from PMEG3020EGW-Q.
Can PMEG3020EGW-QX replace a standard silicon rectifier in an existing 24 V SMPS?
Yes, provided the original design uses a 30 V or higher VR silicon diode rated ≥2 A. Due to its lower VF, PMEG3020EGW-QX will reduce conduction losses and junction temperature-but verify layout thermal relief, reverse recovery noise, and surge current handling, as Schottky devices lack minority-carrier recovery.
Does the SOD123 package support hand soldering for prototyping?
Yes, the SOD123 package is compatible with hand soldering using fine-tip irons and flux, but thermal management is critical: limit iron tip temperature to ≤350 °C, dwell time to <3 seconds per joint, and ensure cathode pad has adequate copper area to prevent delamination or voiding during rework.
