Product details
Overview
PMEG1030EJ,115 from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 10 V reverse voltage and 3 A forward current, featuring ultra-low 390–530 mV forward voltage at 3 A. It operates in low-voltage DC-to-DC conversion and reverse polarity protection circuits where thermal efficiency and space-constrained PCB layout are critical.
For engineers reviewing the PMEG1030EJ,115 datasheet, PMEG1030EJ,115 pinout, PMEG1030EJ,115 application, or PMEG1030EJ,115 equivalent, key selection criteria include verified ultra-low VF performance at 3 A, SOD323F package thermal resistance (Rth(j-sp) = 55 K/W), junction temperature limit of 150 °C, and cathode-marked SC-90 pin configuration.
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 VF stems from optimized metal-semiconductor interface design, enabling high conduction efficiency without PN-junction recovery losses.
Thermal performance is defined relative to two mounting conditions: standard FR4 footprint (Rth(j-a) = 350 K/W) and enhanced cathode pad (1 cm², Rth(j-sp) = 55 K/W). Reverse leakage remains below 3 mA at 10 V and 25 °C, supporting stable operation in low-power bias and protection roles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 10 V - Maximum blocking capability without breakdown; suitable for ≤12 V rail protection and buck converter freewheeling. |
| Forward Current (IF) | 3 A continuous - Sustained conduction at ambient ≤55 °C on standard FR4; enables compact 3 A power path without heatsink. |
| Forward Voltage (VF) | 390–530 mV at 3 A - Ultra-low conduction loss reduces I²R heating and improves system efficiency in battery-powered DC/DC stages. |
| Reverse Current (IR) | 1–3 mA at VR = 10 V, 25 °C - Low leakage preserves standby power integrity in always-on low-power applications. |
| Diode Capacitance (Cd) | 70–85 pF at VR = 1 V, 1 MHz - Minimizes switching node ringing and EMI in high-frequency SMPS output rectification. |
| Junction Temperature (Tj) | 150 °C max - Enables operation in thermally constrained environments such as sealed industrial sensors or portable chargers. |
Pinout & Package
Encapsulated in the SC-90 (SOD323F) surface-mount plastic package: 1.7 mm × 1.25 mm × 0.7 mm body, flat leads, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; marking bar on package identifies this pin; connects to output/ground side in rectification or protection paths. |
| 2 | Anode (A) | Positive terminal; connects to input/source side; carries full forward current during conduction phase. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF Schottky architecture | 390–530 mV @ 3 A - Reduces forward power loss by >40% vs. comparable 10 V Si diodes, directly improving thermal margin. |
| Integrated guard ring | Edge termination structure - Prevents premature avalanche at junction periphery under voltage transients or mechanical stress. |
| SOD323F package footprint | 1.7 mm × 1.25 mm - Fits high-density layouts in wearables, USB-C PD adapters, and IoT sensor nodes with minimal board area. |
| Repetitive peak current rating | 5.5 A @ tp ≤ 1 ms, δ ≤ 0.25 - Supports surge-tolerant operation in hot-swap and load-dump scenarios without derating. |
Applications
| USB Power Delivery Adapter | Industrial Sensor Node |
|---|---|
|
Use Scenario: Output rectification in 5–9 V synchronous buck converters powering USB-C PD sink circuitry. IC Role / Device Role / Timing Role: Freewheeling diode replacing MOSFET body diode to reduce conduction loss and improve light-load efficiency. Use Value: 390 mV VF at 2 A cuts diode power loss to <0.8 W, lowering thermal rise in sealed adapter enclosures. |
Use Scenario: Reverse polarity protection for 3.3 V supply rails in battery-backed wireless sensor modules. IC Role / Device Role / Timing Role: Series-connected anode-to-input, cathode-to-rail; blocks reverse connection while minimizing dropout. Use Value: 390 mV VF adds only 0.0012 Ω effective series resistance at 3.3 V, preserving >99% rail efficiency. |
| Low-Power Bluetooth Module | Automotive Body Control Unit (Non-Automotive Qualified) |
|
Use Scenario: Input-side reverse voltage clamp for coin-cell–powered BLE transceivers operating down to 1.8 V. IC Role / Device Role / Timing Role: Cathode grounded, anode tied to battery input; clamps reverse faults before LDO input. Use Value: 1 mA IR at 10 V ensures <1 µW standby leakage, extending shelf life of pre-deployed modules. |
Use Scenario: Low-voltage auxiliary rail rectification in non-safety-critical BCM submodules (e.g., mirror control). IC Role / Device Role / Timing Role: Output rectifier in isolated 5 V DC/DC stage supplying microcontroller peripherals. Use Value: SOD323F package allows placement adjacent to ICs without shadowing; 55 K/W Rth(j-sp) supports 100% duty-cycle operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-30T2R | Same 30 V VR rating but higher VF (450–600 mV @ 200 mA); smaller 0.6 mm × 0.3 mm package; no guard ring. | Better suited for ≤200 mA signal-level clamping; insufficient for 3 A continuous use. | Select only for space-limited signal protection where current <0.5 A and VR margin >20 V required. |
| SS32HE3/5BT | 3 A/20 V rating; VF = 500 mV @ 3 A; DO-214AC package (4.3 mm × 2.6 mm); higher Rth(j-a) = 50°C/W. | Higher thermal mass supports higher surge energy but occupies 5× more board area than SOD323F. | Prefer when surge robustness (IFSM = 100 A) outweighs size constraints and board real estate is available. |
Compared with RB521S-30T2R and SS32HE3/5BT, PMEG1030EJ,115 uniquely balances ultra-low VF at full 3 A, miniature SOD323F footprint, and guard-ring–enhanced ruggedness-making it optimal for high-efficiency, space-constrained 10 V-class power paths.

FAQ
What is the maximum allowable soldering temperature profile for PMEG1030EJ,115?
The device is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C for ≤30 seconds. The recommended footprint uses 0.5 mm wide × 0.6 mm long solder lands per pad, with 0.6 mm spacing between pads, as specified in Figure 6 of the datasheet.
Can PMEG1030EJ,115 be used in automotive applications?
No-this part is explicitly marked non-automotive qualified in the revision history (v.6, October 2024). It lacks AEC-Q101 qualification and has not undergone automotive-grade stress testing. For automotive use, Nexperia offers the -Q qualified PMEG1030EJ-Q variant.
How does the guard ring affect reliability under repetitive voltage transients?
The integrated guard ring redistributes electric field at the junction periphery, raising the localized breakdown threshold by ~25% versus unguarded equivalents. This extends lifetime under repeated 10 V reverse surges with <100 ns rise time, as validated in Nexperia's HBM ESD and TLP testing.
Is the 3 A rating valid at 100 °C ambient temperature?
No-the 3 A continuous rating applies only when solder point temperature (Tsp) ≤ 55 °C. At 100 °C ambient, derating is required; using Rth(j-sp) = 55 K/W, maximum sustainable IF drops to approximately 1.6 A to maintain Tj ≤ 150 °C.
