Product details
Overview
PMEG2005EGW-QJ from Nexperia is a 20 V, 0.5 A low forward-voltage Schottky barrier rectifier in SOD123 package, featuring typ. VF = 355 mV at 500 mA and typ. IR = 40 µA at 20 V, with integrated guard ring for stress protection and AEC-Q101 qualification for automotive use.
For engineers reviewing the PMEG2005EGW-QJ datasheet, PMEG2005EGW-QJ pinout, PMEG2005EGW-QJ application, or PMEG2005EGW-QJ equivalent, this device is selected for low-loss rectification in space-constrained DC-DC converters, reverse polarity protection circuits, and automotive body electronics where thermal robustness and low conduction loss are critical.
Technical Context
This MEGA Schottky rectifier uses a planar silicon structure with an integrated guard ring to enhance surge immunity and reduce leakage under high dv/dt or reverse-bias stress. Its low VF stems from optimized metal-semiconductor interface design rather than edge termination alone.
The device operates within a junction temperature range of −40 °C to 150 °C and delivers stable performance across automotive ambient conditions (−40 °C to 125 °C), supported by Rth(j-sp) = 29 K/W to cathode solder point on standard FR4 PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum continuous blocking voltage; defines safe operating ceiling in reverse-biased applications like reverse polarity protection. |
| Forward Current (IF) | 0.5 A - Continuous DC current rating at Tsp ≤ 55 °C; supports compact power rail designs without forced cooling. |
| Forward Voltage (VF) | 355 mV typ. at 500 mA - Low conduction loss reduces heat generation and improves efficiency in 3.3 V/5 V DC-DC output stages. |
| Reverse Current (IR) | 40 µA typ. at 20 V - Low leakage preserves battery life in always-on automotive modules and enables reliable low-power standby operation. |
| Diode Capacitance (Cd) | 66 pF typ. at 1 V - Enables fast switching in high-frequency SMPS (≥1 MHz) with minimal capacitive loading on gate drivers or feedback nodes. |
| Junction Temperature (Tj) | 150 °C max - Allows sustained operation in engine bay or under-hood environments without derating below rated current. |
| Thermal Resistance (Rth(j-sp)) | 29 K/W - Enables direct thermal coupling to PCB copper, supporting >0.4 A continuous current on 1 cm² cathode pad without heatsink. |
Pinout & Package
Encapsulated in the compact SOD123 surface-mount plastic package (2.675 mm × 1.6 mm × 1.15 mm), with cathode marked by a bar on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to negative output or ground reference; carries full forward current and serves as primary thermal path to PCB via soldered tab. |
| 2 (A) | Anode | Connected to input or positive rail; functions as current entry point during forward conduction and reverse-blocking node. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances ESD and transient overvoltage tolerance (e.g., ISO 7637-2 pulse 5a) without increasing VF or footprint. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, HAST, and mechanical shock per JESD22 standards. |
| Low thermal resistance | Rth(j-sp) = 29 K/W enables >0.45 A continuous current on standard FR4 with 1 cm² cathode pad, reducing need for thermal vias. |
| Small SOD123 footprint | 2.675 mm × 1.6 mm area allows placement in tight spaces such as LED driver PCBs or infotainment power rails. |
Applications
| Automotive Body Control Module | USB-C Power Delivery Protection |
|---|---|
|
Use Scenario: Reverse polarity protection for 12 V supply inputs in door module ECUs exposed to jump-start transients. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed between connector and LDO input to prevent damage from incorrect battery connection.

IC Role / Device Role / Timing Role: Low-VF Schottky rectifier enabling efficient power path selection without active control circuitry. Use Value: 355 mV VF minimizes voltage loss and self-heating during 3 A peak loads, preserving PD negotiation voltage margins. |
| Industrial Sensor Node Power Rail | Low-Power IoT Battery Management |
|

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 | Higher VF (450 mV typ. @ 0.5 A), same VR (20 V), larger SOD-123FL package (3.5 mm × 1.6 mm). | Less suitable for ultra-low-drop applications but offers higher IFSM (15 A) for surge-heavy industrial inputs. | Select RB050M-30 when surge robustness outweighs conduction loss in non-battery-powered systems. |
| SS22 | Lower IF rating (200 mA), lower VR (20 V), VF = 500 mV typ., SOD-123 package. | Not qualified to AEC-Q101; limited to consumer-grade portable devices with relaxed reliability requirements. | Choose SS22 only for cost-sensitive, non-automotive applications where 0.2 A current suffices and qualification is unnecessary. |
Compared with RB050M-30 and SS22, PMEG2005EGW-QJ uniquely balances AEC-Q101 compliance, 355 mV VF, and 0.5 A rating in the smallest SOD123 variant-making it optimal for space- and efficiency-critical automotive and industrial power rails.

FAQ
Is PMEG2005EGW-QJ suitable for reflow soldering?
Yes, PMEG2005EGW-QJ is qualified for lead-free reflow soldering per JEDEC J-STD-020, with peak temperature up to 260 °C. The SOD123 package outline and recommended footprint (Fig. 8 in datasheet) ensure reliable wetting and alignment during standard PCB assembly processes.
What is the meaning of the 'QJ' suffix in PMEG2005EGW-QJ?
The 'QJ' suffix denotes Nexperia's automotive-grade variant with full AEC-Q101 qualification, traceable lot coding, and extended temperature screening (−40 °C to 150 °C). It is functionally identical to PMEG2005EGW-Q but meets stricter automotive audit and documentation requirements.
Can PMEG2005EGW-QJ replace a standard PN-junction diode in existing designs?
Yes, provided reverse voltage and surge requirements are met: its 20 V VR and 10 A IFSM allow direct substitution for 1N4148 or 1N4001 in low-voltage, low-current paths-but the lower VF (355 mV vs. ~700–1100 mV) will reduce power loss and improve thermal margin without circuit modification.
Does PMEG2005EGW-QJ require external thermal management?
No external heatsink is required: with Rth(j-sp) = 29 K/W and Ptot = 400 mW at Tamb ≤ 25 °C, the device maintains Tj < 125 °C at 0.45 A continuous current on a 1 cm² cathode copper pad-enabling fully passive thermal design in most automotive and industrial PCB layouts.
