Product details
Overview
PMEG3005EGW-QJ from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 30 V reverse voltage and 0.5 A average forward current, featuring low 380 mV typical forward voltage and 40 µA typical reverse leakage at 30 V - deployed in automotive-grade DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG3005EGW-QJ datasheet, PMEG3005EGW-QJ pinout, PMEG3005EGW-QJ application, or PMEG3005EGW-QJ equivalent, key selection criteria include its AEC-Q101 qualification, SOD123 package thermal resistance (190 K/W to solder point), and low VF performance under pulsed 500 mA conditions at 25 °C.
Technical Context
This Schottky rectifier uses a planar die structure with an integrated guard ring to enhance ruggedness against electrical overstress and transient voltage spikes. Its low forward voltage drop stems from optimized metal-semiconductor junction design, enabling high efficiency in low-voltage power conversion stages.
The device operates with a maximum junction temperature of 150 °C and exhibits 55–70 pF diode capacitance at 1 V reverse bias, supporting fast switching in SMPS and reverse-battery protection where low stored charge and minimal recovery loss are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - defines maximum blocking capability in reverse-biased operation without breakdown. |
| Average Forward Current (IF(AV)) | 0.5 A - sustainable DC or square-wave current at Tsp ≤ 145 °C on FR4 PCB. |
| Forward Voltage (VF) | 380 mV typ. at IF = 500 mA - reduces conduction loss and improves efficiency in 3.3 V/5 V rail rectification. |
| Reverse Current (IR) | 40 µA typ. at VR = 30 V - minimizes standby power loss in battery-powered automotive modules. |
| Diode Capacitance (Cd) | 55–70 pF at VR = 1 V, f = 1 MHz - enables stable high-frequency switching up to several MHz in compact DC-DC designs. |
| Thermal Resistance (Rth(j-sp)) | 190 K/W - measured from junction to cathode solder point on standard FR4 footprint, guiding thermal pad layout. |
| Junction Temperature (Tj) | 150 °C max - sets upper limit for continuous operation in under-hood automotive environments. |
Pinout & Package
Encapsulated in a compact SOD123 surface-mount plastic package (2.675 mm × 1.6 mm × 1.15 mm body), with cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative output terminal; marking bar identifies this pin; connects to load ground or return path in reverse-polarity protection. |
| 2 | Anode (A) | Positive input terminal; ties to supply rail or switch node; carries full forward current during conduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and infotainment power supplies. |
| Guard ring integration | Improves ESD robustness and transient overvoltage tolerance without external clamping components. |
| Low VF at 500 mA | 380 mV typical drop enables >95% efficiency in 5 V → 3.3 V buck-derived rectifier stages. |
| SOD123 footprint | Standardized 2-pin outline compatible with automated placement and reflow processes on high-density PCBs. |
| 150 °C junction rating | Supports operation in under-dash and under-hood locations where ambient temperatures exceed 105 °C. |

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 NSSR0530MX | Same 30 V VR, 0.5 A IF(AV), but VF = 420 mV typ. at 500 mA; Rth(j-a) = 350 K/W (free air). | Lacks AEC-Q101 qualification; suitable for industrial but not automotive-critical systems. | Select when cost sensitivity outweighs automotive compliance and thermal performance is less constrained. |
| Vishay VS-30CTQ050-M3 | Higher 5 A IF(AV), TO-220AB package; VF = 470 mV typ. at 5 A; not SMD-compatible. | Designed for high-power AC-DC front ends, not low-profile DC-DC secondaries. | Choose only for through-hole legacy designs requiring higher current headroom and board-level heatsinking. |
Compared with NSSR0530MX and VS-30CTQ050-M3, PMEG3005EGW-QJ delivers superior thermal performance in SMD form factor, guaranteed automotive qualification, and lowest VF among 0.5 A-class Schottkys - making it optimal for space- and efficiency-critical automotive subsystems.

FAQ
Is PMEG3005EGW-QJ suitable for synchronous rectification?
No - PMEG3005EGW-QJ is a passive Schottky rectifier, not a MOSFET-based synchronous rectifier IC. It lacks gate drive interface or control logic. It functions as a freewheeling or output rectifier in non-synchronous topologies, where its low VF and fast recovery provide efficiency gains without control complexity.
What is the meaning of the 'QJ' suffix in PMEG3005EGW-QJ?
The 'QJ' suffix denotes Nexperia's automotive-grade variant with full AEC-Q101 qualification and extended temperature screening. It reflects tighter process controls, enhanced traceability, and additional reliability testing beyond the base 'Q' version, ensuring suitability for under-hood and safety-related vehicle systems.
Can PMEG3005EGW-QJ replace a standard silicon diode in a 5 V supply?
Yes - with VR = 30 V and VF ≈ 380 mV (vs. ~700 mV for silicon), it reduces conduction loss by >45% at 500 mA. However, ensure reverse leakage (40 µA at 30 V) is acceptable in your standby budget, and verify thermal design since Schottky junctions are more sensitive to ambient temperature rise than silicon.
Does the SOD123 package support hand soldering for prototyping?
Yes - the SOD123 footprint is compatible with fine-tip soldering irons and hot-air rework stations. Use the recommended reflow profile (peak 260 °C, 30 s max above 217 °C) and ensure adequate cathode pad area (1 cm² per Nexperia's thermal spec) to maintain reliability during manual assembly and thermal cycling.
