Product details
Overview
PMEG2005AEA/DG,115 from Nexperia is a 20 V, 0.5 A Schottky barrier rectifier in SOD323 (SC-76) package, featuring 355–390 mV forward voltage at 500 mA, ≤200 µA reverse leakage at 20 V, and integrated guard ring for stress protection. It serves as a low-loss unidirectional current switch in compact DC/DC converters and polarity protection circuits.
For engineers reviewing the PMEG2005AEA/DG,115 datasheet, PMEG2005AEA/DG,115 pinout, PMEG2005AEA/DG,115 application, or PMEG2005AEA/DG,115 equivalent, key selection criteria include ultra-low VF performance, SOD323 thermal resistance (Rth(j-a) = 450 K/W), surge current capability (IFSM = 10 A), and non-automotive qualification status.
Technical Context
This 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 barrier height yields sub-400 mV conduction loss at rated current while maintaining <200 µA reverse leakage at full 20 V rating.
The device exhibits 66–80 pF junction capacitance at 1 V reverse bias and 1 MHz, supporting fast switching in high-frequency DC/DC topologies. Thermal design must account for Rth(j-sp) = 210 K/W to solder point and Rth(j-a) = 450 K/W on standard FR4, with thermal runaway considerations due to reverse power dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum blocking voltage before breakdown; defines safe operating range in clamping and reverse polarity protection. |
| Forward Current (IF) | 0.5 A continuous - Sustained conduction capability; sets maximum steady-state load current in power path applications. |
| Forward Voltage (VF) | 355–390 mV @ 500 mA - Directly determines conduction loss (Pcond ≈ 178–195 mW); critical for efficiency in low-voltage rails. |
| Reverse Current (IR) | 40–200 µA @ 20 V - Defines leakage-induced standby power loss and signal integrity in high-impedance nodes. |
| Junction Capacitance (Cd) | 66–80 pF @ 1 V, 1 MHz - Impacts switching speed and EMI in high-frequency rectification; limits usable frequency range. |
| Surge Current (IFSM) | 10 A @ 8 ms - Withstands short-duration inrush or fault currents without degradation; enables robust input stage design. |
| Thermal Resistance (Rth(j-a)) | 450 K/W - Indicates self-heating under ambient conditions; requires PCB copper area planning for thermal management. |
Pinout & Package
Encapsulated in a SOD323 (SC-76) surface-mount plastic package measuring 1.7 mm × 1.25 mm × 0.95 mm with 1.3 mm lead pitch and tin-plated terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to higher-potential node in forward bias; carries full load current and dissipates majority of heat in typical layout. |
| 2 (A) | Anode | Connected to lower-potential node; forms the return path; requires thermal relief consideration when routed to ground planes. |
Key Features
| Feature | Design Value |
|---|---|
| Very low forward voltage | VF = 355–390 mV @ 500 mA reduces conduction loss by >40% vs. standard silicon diodes in 3.3 V/5 V rails. |
| Integrated guard ring | Suppresses edge breakdown under mechanical or electrical stress, improving long-term reliability in compact layouts. |
| High surge current rating | IFSM = 10 A enables use in systems with high-capacitance inputs or transient overloads without derating. |
| Ultra-small SMD footprint | SOD323 package (1.7 × 1.25 mm) supports miniaturized designs in space-constrained wearables and IoT endpoints. |
Applications
| Low Voltage Rectification | High Efficiency DC/DC Conversion |
|---|---|
|
Use Scenario: Converting 3.3 V or 5 V USB-supplied power to intermediate rails in portable instrumentation. IC Role / Device Role / Timing Role: Unidirectional current switch providing low-loss forward conduction and reverse isolation. Use Value: 355–390 mV VF minimizes voltage drop and thermal rise, preserving regulation margin and battery runtime. |
Use Scenario: Output rectification in synchronous-buck-derived isolated flyback or buck-boost converters. IC Role / Device Role / Timing Role: Secondary-side freewheeling diode handling high-frequency switching transitions. Use Value: 66–80 pF Cd and low stored charge enable faster turn-off, reducing switching losses and EMI generation. |
| Voltage Clamping | Inverse Polarity Protection |
|
Use Scenario: Suppressing inductive kickback spikes across solenoids or relay coils in industrial control modules. IC Role / Device Role / Timing Role: Transient voltage clamp limiting peak reverse excursion to ≤20 V. Use Value: 20 V VR rating and guard ring ensure stable clamping behavior without avalanche degradation over time. |
Use Scenario: Protecting microcontroller-based sensor nodes from accidental reverse battery connection. IC Role / Device Role / Timing Role: Series-blocking element placed between power source and system input. Use Value: 0.5 A IF rating supports typical sensor node loads; low VF avoids unnecessary voltage loss in supply path. |
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, SOD-523 package (1.2 × 0.8 mm) | Lower current rating and smaller footprint; suitable only for sub-200 mA loads | Select when board space is more constrained than current capacity and 30 V margin is required. |
| SS12 | 20 V VR, 1 A IF, VF = 500 mV @ 1 A, SMA package (4.5 × 2.7 mm) | Higher current but larger size and higher VF; lacks guard ring | Choose for higher-current legacy designs where thermal mass outweighs footprint constraints. |
Compared with RB520S-30T1G and SS12, PMEG2005AEA/DG,115 uniquely balances 0.5 A capability, ultra-low 355–390 mV VF, and SOD323 miniaturization-making it optimal for space-limited, efficiency-critical 3.3 V/5 V power paths where guard ring reliability is required.

FAQ
Is PMEG2005AEA/DG,115 qualified for automotive applications?
No. The datasheet explicitly states this part is non-automotive qualified. It has not undergone AEC-Q101 testing or qualification. For automotive-grade alternatives, consult Nexperia's PMEG2005AEA-Q series, which features automotive qualification and extended temperature validation.
What is the maximum allowable junction temperature during continuous operation?
The absolute maximum junction temperature is 150 °C per IEC 60134. Continuous operation must remain within this limit, requiring thermal design that accounts for Rth(j-a) = 450 K/W on standard FR4 and power dissipation derived from VF × IF + IR × VR.
How does the integrated guard ring improve reliability?
The guard ring mitigates electric field crowding at the die edge, preventing premature breakdown under mechanical stress (e.g., PCB flexure) or high dv/dt transients. This extends operational lifetime in compact, high-density assemblies where edge effects dominate failure modes.
Can PMEG2005AEA/DG,115 replace a standard silicon diode in an existing design?
Yes-if reverse voltage requirements are ≤20 V and forward current ≤0.5 A. Its lower VF improves efficiency and reduces heating, but its higher reverse leakage (vs. silicon) may affect high-impedance bias networks or precision reference circuits.
