Product details
Overview
PMEG2005AEA from Nexperia is a 20 V, 0.5 A Schottky barrier rectifier in SOD323 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 path in compact DC/DC converters and reverse-polarity protection circuits.
For engineers reviewing the PMEG2005AEA datasheet, PMEG2005AEA pinout, PMEG2005AEA application, or PMEG2005AEA equivalent, key selection criteria include its ultra-low VF, 10 A non-repetitive surge rating, SOD323 footprint compatibility, and thermal resistance of 450 K/W (junction-to-ambient on FR4).
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low barrier height enables sub-400 mV conduction at rated current while maintaining 20 V reverse blocking capability.
The device operates within −55 °C to 150 °C ambient range, with junction temperature limited to 150 °C. Thermal resistance values-450 K/W (j-a), 210 K/W (j-sp), and 90 K/W (j-cathode tab)-are defined for specific PCB mounting conditions per IEC 60134 limiting values.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum continuous reverse bias before breakdown; defines safe operating ceiling in clamping and flyback snubber applications. |
| Forward Current (IF) | 0.5 A - Continuous DC current handling capacity; supports low-power rail rectification without derating at 25 °C ambient. |
| Forward Voltage (VF) | 355–390 mV @ 500 mA - Enables <175 mW conduction loss at full load, critical for >90% efficiency in 3.3 V or 5 V DC/DC stages. |
| Reverse Current (IR) | 40–200 µA @ 20 V - Low leakage preserves battery life in always-on low-power systems and minimizes standby loss. |
| Diode Capacitance (Cd) | 66–80 pF @ 1 V, 1 MHz - Limits high-frequency switching noise and EMI in synchronous rectifier and RF-coupled clamp circuits. |
| Surge Current (IFSM) | 10 A @ 8 ms - Withstands inrush and fault transients in USB-powered devices and hot-swap interfaces without failure. |
| Junction Temp (Tj) | 150 °C - Maximum allowable junction temperature; sets thermal design margin when used with 450 K/W j-a resistance on standard FR4. |
Pinout & Package
Encapsulated in SOD323 (SC-76) plastic surface-mount package: 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, tin-plated terminations compatible with reflow and wave soldering per Figures 5 and 6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to higher-potential node in forward conduction; primary heat path to PCB via cathode pad (Rth(j-sp) = 210 K/W). |
| 2 (A) | Anode | Connected to lower-potential node; carries full forward current; no thermal relief required due to low power dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Very low forward voltage | 355–390 mV at 500 mA reduces conduction loss by >40% vs. standard silicon diodes, directly improving light-load efficiency. |
| Integrated guard ring | Suppresses edge-related avalanche breakdown, enabling stable 20 V reverse operation without field plate redesign or layout margin increase. |
| High surge current rating | 10 A non-repetitive peak withstands USB inrush, capacitor charging spikes, and ESD-induced transients without parametric shift. |
| Ultra-small SMD package | SOD323 footprint (1.7 × 1.25 mm) allows placement in space-constrained wearables and IoT sensor nodes where board area is premium. |
Applications
| USB Power Input Protection | Low-Voltage DC/DC Output Rectification |
|---|---|
Use Scenario: Preventing damage from reversed USB cable insertion in portable chargers and BLE peripherals. IC Role / Device Role / Timing Role: Unidirectional current gate placed between VBUS and system input rail. Use Value: 355 mV VF ensures <0.2 V drop at 500 mA, preserving >96% of 5 V input for downstream LDOs or buck converters. |
Use Scenario: Secondary-side rectification in 3.3 V synchronous buck converter for microcontroller power rails. IC Role / Device Role / Timing Role: Freewheeling path during high-side switch off-time; replaces active MOSFET in cost-sensitive designs. Use Value: 66–80 pF capacitance minimizes switching node ringing and EMI generation at 1–2 MHz switching frequencies. |
| Voltage Clamping in Signal Lines | Inverse Polarity Protection for Coin Cell Devices |
Use Scenario: Protecting ADC inputs or GPIOs from ESD or overvoltage transients up to ±15 V. IC Role / Device Role / Timing Role: Clamp diode tied between signal line and supply/rail; conducts only during overvoltage events. Use Value: 20 V VR rating provides 5 V safety margin above 15 V max transient, while low IR avoids DC loading of sensitive analog nodes. |
Use Scenario: Blocking reverse current when CR2032 coin cell is inserted backward in medical sensors or remote controls. IC Role / Device Role / Timing Role: Series-connected anode-to-battery cathode, blocking reverse conduction path. Use Value: 40 µA typical IR at 3 V ensures <13 nA reverse leakage-negligible for multi-year battery life in 10 µA sleep-mode devices. |
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 - higher voltage rating but lower current capacity. | Better suited for 12 V rail protection; insufficient for sustained 500 mA loads without thermal derating. | Select when reverse voltage margin >10 V is required and average current stays below 200 mA. |
| SS12 | 20 V VR, 1 A IF, VF = 500 mV @ 1 A - larger SOD-123 package, higher VF, higher current rating. | Acceptable for same voltage class but occupies 2.5× more board area and dissipates ~40% more heat at 500 mA. | Choose only if 1 A continuous current is needed and SOD323 size constraint does not apply. |
Compared with RB520S-30T1G and SS12, PMEG2005AEA uniquely balances 0.5 A current, 20 V rating, ultra-low VF, and minimal SOD323 footprint-making it optimal for space- and efficiency-critical 3.3 V/5 V embedded power paths.

FAQ
What is the maximum allowable junction temperature for PMEG2005AEA?
The absolute maximum junction temperature is 150 °C per IEC 60134 limiting values. Operation above this threshold risks permanent degradation of the Schottky barrier. Derating is required above 85 °C ambient, especially when mounted on thin FR4 without thermal relief, due to its 450 K/W junction-to-ambient thermal resistance.
Can PMEG2005AEA be used in automotive applications?
No-PMEG2005AEA is explicitly marked as non-automotive qualified in its revision history (v.3, Jan 2023). It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation. For automotive use, Nexperia offers the PMEG2005AEA-Q variant, which undergoes additional stress testing and lot traceability.
How does the integrated guard ring affect PCB layout requirements?
The guard ring eliminates need for extra clearance around the die edges, allowing standard SOD323 land patterns (per Figure 5) without enlarged keep-out zones. Layouts may follow Nexperia's recommended 0.5 mm solder mask opening and 0.6 mm copper pad per terminal-no additional field-shaping copper pours or guard traces are required.
Is PMEG2005AEA suitable for high-frequency switching above 10 MHz?
Its 66–80 pF capacitance at 1 V reverse bias makes it usable up to ~50 MHz in clamping roles, but forward recovery time is not specified. For >10 MHz synchronous rectification, parasitic inductance of the SOD323 package becomes dominant; layout must minimize loop area, and alternative chip-scale packages like DFN1006 may offer better RF performance.
