Product details
Overview
PMEG2005EJ from Nexperia is a 20 V, 0.5 A planar Schottky barrier rectifier in SOD323F (SC-90) package, featuring 355–390 mV forward voltage at 500 mA, integrated guard ring for stress protection, and optimized for low-voltage DC-to-DC conversion in space-constrained power rails.
For engineers reviewing the PMEG2005EJ datasheet, PMEG2005EJ pinout, PMEG2005EJ application, or PMEG2005EJ equivalent, key selection criteria include ultra-low VF, thermal resistance to solder point (55 K/W), reverse leakage ≤200 µA at 20 V, and compatibility with reflow-soldered FR4 PCBs using standard 1.7 mm × 1.25 mm footprints.
Technical Context
This MEGA Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown under high electric field stress, enabling reliable operation up to 150 °C junction temperature. Its low VF stems from optimized metal-semiconductor interface design rather than barrier height reduction alone.
The device exhibits pulsed forward current capability up to 10 A (8 ms square wave) and reverse recovery time effectively zero-critical for high-frequency switching topologies. Thermal performance is defined for two mounting conditions: standard footprint (Rth(j-a) = 350 K/W) and enhanced cathode pad (Rth(j-sp) = 55 K/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum blocking voltage before breakdown; defines usable input range in 12 V or 15 V rail protection circuits. |
| Forward Current (IF) | 0.5 A continuous - Rated for steady-state conduction at Tsp ≤ 55 °C; supports compact buck converter outputs. |
| Forward Voltage (VF) | 355–390 mV @ 500 mA - Enables <1% conduction loss in 3.3 V/5 V systems; reduces heat generation vs. standard Schottkys. |
| Reverse Leakage (IR) | ≤200 µA @ 20 V - Low leakage preserves battery life in always-on low-power applications like IoT sensors. |
| Diode Capacitance (Cd) | 66–80 pF @ 1 V - Minimizes switching node ringing in >1 MHz DC-DC converters; aids EMI control. |
| Junction Temperature (Tj) | 150 °C - Allows operation in thermally dense environments without derating below full current rating. |
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 package; connects to load ground or return path. |
| 2 | Anode (A) | Input terminal for forward conduction; connects to source rail or switch node in buck topology. |
Key Features
| Feature | Design Value |
|---|---|
| Very low forward voltage | 355–390 mV at 500 mA enables ≥95% efficiency in 3.3 V output buck converters with minimal heatsinking. |
| Integrated guard ring | Suppresses edge-related avalanche failure under transient overvoltage, improving reliability in unregulated input stages. |
| Flat lead SMD package | SOD323F footprint allows automated placement and reflow compatibility while minimizing board area versus SOD123. |
| Low thermal resistance to solder point | 55 K/W (cathode pad = 1 cm²) enables direct thermal coupling to PCB copper, reducing junction-to-board delta-T by >40% vs. standard layout. |
Applications
| USB Power Delivery Interface | Wearable Device Battery Charging |
|---|---|
Use Scenario: Reverse polarity protection at USB-C port input prior to buck-boost controller. IC Role / Device Role: Unidirectional current gate preventing damage from misinserted cables. Use Value: 355 mV VF limits voltage drop to <0.4% of 5 V rail, preserving headroom for downstream regulation. |
Use Scenario: Output rectification in miniature 500 mA buck charger IC for Li-ion coin cells. IC Role / Device Role: Synchronous rectifier replacement in low-IQ charging path. Use Value: 200 µA max IR at 20 V prevents >1 µA standby drain-critical for multi-year battery life. |
| Industrial Sensor Node Power Rail | Automotive Body Control Module (Non-Automotive Qualified) |
Use Scenario: Low-voltage rectification for 3.3 V microcontroller supply derived from 5 V CAN transceiver rail. IC Role / Device Role: Input protection and noise filtering element in isolated power domain. Use Value: 66–80 pF capacitance minimizes high-frequency coupling into sensitive analog sensor inputs. |
Use Scenario: Reverse polarity clamp in 12 V accessory circuit (e.g., LED interior lighting) during prototyping phase. IC Role / Device Role: Non-automotive-qualified safeguard against accidental battery reversal. Use Value: 150 °C Tj rating supports operation in enclosed enclosures near heat-generating ECUs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G | 30 V VR, 200 mA IF, VF = 370 mV @ 100 mA - lower current rating, higher voltage margin. | Preferred where 30 V headroom needed but load current <200 mA; unsuitable for 0.5 A DC paths. | Select when system input may exceed 20 V transiently but average current is low. |
| NSR0230HT1G | 30 V VR, 200 mA IF, VF = 360 mV @ 100 mA - same current limit, slightly higher Cd (100 pF). | Better for cost-sensitive consumer designs; higher capacitance increases switching node oscillation risk above 2 MHz. | Choose for non-critical 3.3 V rails where layout allows extra EMI filtering. |
Compared with PMEG2005EJ, RB520S-30T1G trades 0.5 A capacity for 10 V higher blocking voltage, while NSR0230HT1G offers identical VF but reduced current handling and higher capacitance-making PMEG2005EJ optimal for space-limited 0.5 A DC-DC outputs requiring minimal conduction loss and thermal resistance.

FAQ
What is the maximum continuous forward current for PMEG2005EJ?
The PMEG2005EJ is rated for 0.5 A continuous forward current at solder point temperature ≤55 °C. This rating assumes FR4 PCB mounting with standard footprint per datasheet condition [1]. Exceeding this current without thermal derating risks junction temperature exceeding 150 °C, triggering permanent degradation.
Does PMEG2005EJ have automotive qualification?
No. Per Nexperia's revision history (October 2022), PMEG2005EJ is explicitly designated as non-automotive qualified. It lacks AEC-Q101 stress testing and is not approved for safety-critical vehicle systems. Automotive alternatives must be selected from Nexperia's -Q qualified series, such as PMEG2005EH,115.
How does the integrated guard ring improve reliability?
The guard ring mitigates electric field crowding at the silicon periphery, suppressing premature edge breakdown under reverse bias transients. This extends operational lifetime in applications exposed to load dump or inductive kick events, particularly in DC-DC converters with unshielded inductors or long PCB traces.
What is the recommended reflow soldering footprint?
The official footprint specifies 0.5 mm × 0.6 mm solder lands for each terminal, with 0.6 mm solder resist openings and 0.5 mm paste apertures-detailed in Figure 5 of the datasheet. Deviating from this layout risks tombstoning or insufficient thermal transfer to the cathode pad, degrading Rth(j-sp) performance.
