Product details
Overview
PMEG1020EJ,115 from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 10 V reverse voltage and 2 A forward current, featuring ultra-low forward voltage (350–460 mV at 2 A) in a SOD323F (SC-90) surface-mount package. It serves as a low-loss unidirectional switch in DC-to-DC converters and polarity protection circuits for portable and battery-powered systems.
For engineers reviewing the PMEG1020EJ,115 datasheet, PMEG1020EJ,115 pinout, PMEG1020EJ,115 application, or PMEG1020EJ,115 equivalent, key selection criteria include forward voltage drop at 2 A, thermal resistance to solder point (150 K/W), reverse leakage at 5–10 V, diode capacitance (40–50 pF), and SOD323F footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky rectifier uses a planar die structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low VF stems from optimized metal-semiconductor interface and thin epitaxial layer design, enabling operation at junction temperatures up to 150 °C.
The device exhibits strong temperature dependence in both forward conduction (VF decreases with rising Tamb) and reverse leakage (IR increases >3× from −40 °C to 85 °C). Thermal performance is defined relative to two mounting conditions: standard FR4 footprint (Rth(j-a) = 350 K/W) and enhanced cathode pad (Rth(j-sp) = 150 K/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 10 V - Maximum blocking capability before avalanche onset; defines use in ≤10 V rail systems. |
| Forward Current (IF) | 2 A continuous - Sustained conduction limit at Tsp ≤ 55 °C; supports compact power stages. |
| Forward Voltage (VF) | 350–460 mV at 2 A - Ultra-low conduction loss; reduces heat generation vs. standard Schottkys. |
| Reverse Current (IR) | 0.7–3 mA at VR = 5–10 V - Low leakage preserves efficiency in standby and light-load modes. |
| Diode Capacitance (Cd) | 40–50 pF at VR = 5 V - Enables fast switching in high-frequency DC/DC topologies (≥1 MHz). |
| Thermal Resistance (Rth(j-sp)) | 150 K/W - Junction-to-solder-point value with 1 cm² cathode pad; guides thermal layout for <1 W dissipation. |
| Junction Temperature (Tj) | 150 °C max - Absolute limit for safe operation; requires thermal derating above Tamb = 25 °C. |
Pinout & Package
Encapsulated in a SOD323F (SC-90) plastic SMD package measuring 1.7 mm × 1.25 mm × 0.7 mm, with flat leads and standard footprint per Figure 5 in the datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative output terminal; connects to ground or return path; largest thermal pad area for heat extraction. |
| 2 | Anode (A) | Positive input terminal; carries forward current into load; smaller pad than cathode. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF at 2 A | 350–460 mV - Reduces conduction loss by ≥25% vs. comparable 10 V Schottkys, improving efficiency in 3.3 V/5 V buck converters. |
| Integrated guard ring | Edge termination structure - Suppresses premature breakdown at high dv/dt or reverse transients, enhancing ruggedness in noisy environments. |
| SOD323F package | 1.7 mm × 1.25 mm footprint - Enables high-density placement in space-constrained applications like wearables and IoT sensors. |
| Low Cd (40–50 pF) | Capacitance at 5 V reverse bias - Minimizes switching losses and EMI in MHz-range synchronous rectifiers. |
Applications
| USB Power Delivery Protection | Wearable Device Charging Circuit |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-30T1G | 30 V VR, 200 mA IF, VF = 370 mV @ 100 mA - Higher voltage rating but lower current capacity. | Designed for signal-level clamping and low-current bias rails, not 2 A power paths. | Select only when reverse voltage margin >20 V is required and load current remains ≤200 mA. |
| SS12 | 20 V VR, 1 A IF, VF = 500 mV @ 1 A - Larger SOD-123 package, higher VF, no guard ring. | Targeted at cost-sensitive industrial supplies where thermal density and transient immunity are secondary. | Choose if board space permits larger footprint and 500 mV VF is acceptable for 1 A loads. |
Compared with RB521S-30T1G and SS12, PMEG1020EJ,115 uniquely delivers 2 A current handling with sub-460 mV VF in the smallest SOD323F outline, making it optimal for miniaturized, high-efficiency 10 V-class power rails where thermal and space constraints dominate.

FAQ
What is the maximum allowable soldering temperature profile for PMEG1020EJ,115?
The device is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature of 260 °C for ≤30 seconds. The recommended footprint uses 0.5 mm × 0.6 mm solder lands per pad (Figure 5), and thermal relief must preserve the 1 cm² cathode pad for Rth(j-sp) = 150 K/W performance.
Can PMEG1020EJ,115 be used in automotive applications?
No - this part is explicitly marked non-automotive qualified in the revision history (v.6, 20250930). It lacks AEC-Q101 qualification, automotive-grade screening, and guaranteed operation over −40 °C to +125 °C extended ambient range. Use PMEG1020EJ-Q series for automotive designs.
How does forward voltage vary with temperature and current?
VF decreases with rising temperature: at 2 A, typical VF drops from ~460 mV at −40 °C to ~350 mV at 25 °C and ~280 mV at 85 °C (Fig. 1). At fixed temperature, VF rises logarithmically with current - e.g., 170–200 mV at 0.1 A, 280–350 mV at 1 A, and 350–460 mV at 2 A (Table 7).
Is the SOD323F package compatible with automated optical inspection (AOI)?
Yes - the SOD323F outline features coplanar flat leads and standardized marking "CB" (Table 4), enabling reliable AOI detection. The 0.25 mm lead thickness and 0.65 mm lead width (Fig. 4) meet IPC-A-610 Class 2/3 solder joint inspection criteria when using the recommended reflow footprint.
