Product details
Overview
PMEG2010EAZ from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, rated at 20 V reverse voltage and 1 A forward current, featuring ultra-low forward voltage (480–550 mV @ 1 A) and optimized for high-speed switching in space-constrained PCB layouts.
For engineers reviewing the PMEG2010EAZ datasheet, PMEG2010EAZ pinout, PMEG2010EAZ application, or PMEG2010EAZ equivalent, key selection criteria include low VF clamping performance, SOD323 thermal resistance (220 K/W on 10×10 mm FR4), reverse leakage (<50 µA @ 15 V), and diode capacitance (19–25 pF @ 5 V).
Technical Context
This Schottky diode employs a planar silicon structure with an integrated guard ring to enhance ruggedness against electrical overstress and transient voltage spikes. Its low barrier height enables fast recovery (ultra-high-speed switching) and minimal conduction loss.
Thermal design is constrained by junction-to-ambient resistance-220 K/W on small PCB pads and 180 K/W on larger 40×40 mm copper areas-requiring careful layout consideration for continuous 1 A operation at elevated ambient temperatures up to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V maximum - defines maximum blocking capability before breakdown in protection/clamping circuits |
| Forward Current (IF) | 1 A continuous - supports sustained power rail or signal path conduction without derating at 25 °C |
| Forward Voltage (VF) | 480–550 mV @ 1 A - reduces conduction loss and self-heating in high-efficiency DC/DC or OR-ing applications |
| Reverse Current (IR) | 10–50 µA @ 15 V - ensures low standby leakage in battery-powered or always-on systems |
| Diode Capacitance (Cd) | 19–25 pF @ 5 V - enables use in RF detection or high-frequency clamp circuits without excessive signal distortion |
| Junction Temperature (Tj) | 150 °C max - sets upper thermal limit for reliability under pulsed or continuous load conditions |
| Thermal Resistance (Rth(j-a)) | 220 K/W (10×10 mm FR4) - determines temperature rise per watt dissipated in typical compact PCB layouts |
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, this diode uses a two-terminal configuration optimized for automated placement and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to higher-potential node in forward bias; polarity-sensitive terminal for correct orientation in clamping or rectification paths |
| 2 (A) | Anode | Connected to lower-potential node in forward bias; directionally critical for ESD protection and reverse polarity safeguarding |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Improves robustness against ESD and voltage transients without external circuitry or layout overhead |
| Ultra-low VF | Enables >95% efficiency in low-voltage OR-ing and power-path selection at 3.3 V or 5 V rails |
| SOD323 footprint | Reduces board area by >60% vs. SOD123 while maintaining manufacturability on standard SMT lines |
| 150 °C junction rating | Supports operation in sealed enclosures or near heat-generating components without forced cooling |
Applications
| USB Power Path Protection | Low-Voltage DC/DC Output Clamp |
|---|---|
Use Scenario: Preventing backfeed and overvoltage during USB OTG or dual-power-source arbitration in portable devices. IC Role / Device Role: Reverse-polarity and overvoltage clamp diode placed between VBUS and system rail. Use Value: 480 mV VF minimizes voltage drop across the path, preserving regulated 5 V delivery under 1 A load. | Use Scenario: Suppressing flyback spikes from synchronous buck converter output stages during light-load discontinuous conduction mode. IC Role / Device Role: Snubber diode clamping inductor-induced voltage overshoot at the output capacitor node. Use Value: 25 pF capacitance and sub-1 ns recovery prevent resonance with output filter inductance, reducing EMI. |
| ESD-Sensitive Signal Line Clamping | Li-ion Battery Charging Path Isolation |
Use Scenario: Protecting I²C, UART, or GPIO lines from ±8 kV contact ESD events per IEC 61000-4-2. IC Role / Device Role: Low-capacitance shunt diode tied between signal line and ground or rail. Use Value: 19 pF capacitance avoids signal integrity degradation on 1 MHz I²C buses while clamping transients below 20 V. | Use Scenario: Enabling independent charging of parallel Li-ion cells while preventing cross-cell discharge during charge termination. IC Role / Device Role: OR-ing diode in series with each cell's charge path to enforce unidirectional current flow. Use Value: 10 µA max IR at 5 V ensures <1 µW standby loss per diode, extending shelf life in battery management modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode 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 | Better suited for low-current signal clamping where 20 V margin is insufficient | Select when reverse voltage headroom >20 V is required and average current stays below 200 mA |
| SS12 | 20 V VR, 1 A IF, VF = 550 mV @ 1 A, DO-214AC package - same ratings but larger footprint | Preferred for high-reliability industrial designs requiring manual rework or thermal mass | Choose when SOD323 size is impractical or when higher thermal mass improves long-term stability under cyclic loads |
Compared with RB520S-30T1G and SS12, PMEG2010EAZ delivers optimal balance of low VF, 1 A capability, and ultra-compact SOD323 packaging-making it ideal for modern portable electronics where board space and conduction loss are primary constraints.

FAQ
What is the maximum allowable peak forward surge current for PMEG2010EAZ?
The non-repetitive peak forward current (IFSM) is rated at 5 A for an 8.3 ms half-sine wave pulse with initial junction temperature at 25 °C. This value supports brief inrush or fault-current events but must not be exceeded repeatedly without thermal analysis to avoid permanent junction damage.
Can PMEG2010EAZ be used in automotive applications?
No-PMEG2010EAZ is explicitly marked as non-automotive qualified in its revision history. It lacks AEC-Q101 qualification and has not undergone automotive-grade stress testing. For automotive use, Nexperia offers the PMEG2010EA-Q series with full qualification and extended temperature validation.
How does the guard ring affect layout requirements?
The integrated guard ring enhances ESD robustness without requiring additional PCB guard traces or spacing. Layout follows standard SOD323 footprints (Fig. 5 and Fig. 6 in datasheet); no extra keep-out zones or isolation gaps beyond those specified for thermal management are needed.
Is the marking code 'E1' unique to PMEG2010EAZ?
Yes-the marking code 'E1' is assigned exclusively to PMEG2010EAZ per Nexperia's official marking table. It appears on the top surface of the SOD323 package and serves as the visual identifier for traceability and counterfeit prevention during assembly and inspection.
