Product details
Overview
PMEG3005EJ,115 from Nexperia is a 30 V, 0.5 A planar Schottky barrier rectifier in SOD323F (SC-90) package, featuring 380–430 mV forward voltage at 500 mA, <150 µA reverse leakage at 30 V, and 55–70 pF junction capacitance - optimized for low-loss DC/DC conversion and reverse polarity protection in space-constrained power rails.
For engineers reviewing the PMEG3005EJ,115 datasheet, PMEG3005EJ,115 pinout, PMEG3005EJ,115 application, or PMEG3005EJ,115 equivalent, this device serves as a high-efficiency, low-VF discrete diode for battery-powered systems, USB power paths, and compact SMPS where thermal performance and footprint are critical.
Technical Context
This MEGA Schottky rectifier uses a planar die structure with integrated guard ring for enhanced ESD and surge robustness. Its low forward voltage stems from optimized metal-semiconductor interface design, enabling operation up to 150 °C junction temperature without thermal runaway under defined PCB mounting conditions.
Thermal resistance is specified at 150 K/W (junction-to-solder point) and 350 K/W (junction-to-ambient), reflecting its dependency on cathode pad area (1 cm² recommended). Reverse current remains below 150 µA at rated 30 V, supporting stable blocking in low-power bias networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Reverse Voltage | 30 V - supports input rails up to 24 V nominal with 25 % safety margin against transients |
| Max Forward Current | 0.5 A continuous - suitable for output rectification in sub-1 W DC/DC converters |
| Forward Voltage (IF = 500 mA) | 380–430 mV - reduces conduction loss by >40 % vs. standard silicon diodes at same current |
| Reverse Leakage (VR = 30 V) | 40–150 µA - enables low-quiescent-current standby operation in always-on circuits |
| Junction Capacitance | 55–70 pF at 1 V - minimizes switching noise and improves efficiency in high-frequency (>1 MHz) buck converters |
| Thermal Resistance (j-sp) | 150 K/W - requires ≥1 cm² cathode copper pour for reliable 0.5 A operation at ambient ≤55 °C |
| Operating Junction Temp | −65 to +150 °C - qualified for industrial temperature range without derating below 55 °C ambient |
Pinout & Package
Encapsulated in SOD323F (SC-90), a 1.7 mm × 1.25 mm × 0.7 mm surface-mount plastic package with flat leads and cathode-marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output node for rectified current; marked by bar on top surface; connects to load ground or return path |
| 2 | Anode (A) | Input node for unidirectional current flow; ties to input rail or switch node in buck topology |
Key Features
| Feature | Design Value |
|---|---|
| Very low forward voltage | 380–430 mV @ 500 mA enables >95 % efficiency in 3.3 V → 1.8 V buck converters |
| Integrated guard ring | Improves ruggedness against ESD (IEC 61000-4-2 Level 4) and repetitive surge stress in portable electronics |
| Small SOD323F footprint | 1.7 mm × 1.25 mm area saves >60 % board space vs. SOD123 while maintaining solder joint reliability |
| Low junction capacitance | 55–70 pF minimizes reverse recovery charge (Qrr ≈ 0 nC), eliminating switching spikes in high-dV/dt environments |
Applications
| USB Power Input Protection | Low-Power DC/DC Converter Output |
|---|---|
|
Use Scenario: Preventing damage from reversed USB cable insertion in portable chargers and peripherals. IC Role / Device Role / Timing Role: Unidirectional current gate placed between USB VBUS and system input rail. Use Value: 380 mV VF limits voltage drop to <1 % of 5 V supply, preserving regulation margin for downstream LDOs. |
Use Scenario: Rectifying synchronous buck converter output in wearables and sensor nodes. IC Role / Device Role / Timing Role: Freewheeling diode replacing MOSFET body diode during low-side switch off-time. Use Value: Near-zero Qrr eliminates shoot-through risk and reduces EMI in 2–3 MHz switching designs. |
| Battery Backup Switchover | Reverse Polarity Protection |
|
Use Scenario: Seamless transition between main supply and coin-cell backup in real-time clocks and memory retention circuits. IC Role / Device Role / Timing Role: OR-ing diode isolating primary and backup power domains. Use Value: 40 µA max reverse leakage at 3 V ensures <1 µA total quiescent drain from backup cell over 10-year shelf life. |
Use Scenario: Protecting 3.3 V microcontroller inputs from accidental negative supply connection. IC Role / Device Role / Timing Role: Series-blocking diode on VDD line with cathode toward MCU. Use Value: 0.43 V forward drop allows full 3.3 V rail delivery while surviving −15 V reverse fault indefinitely. |
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 | Higher VF (450–520 mV @ 500 mA); same 30 V rating; SOD-523 package (smaller, 1.2 × 0.8 mm) | Less thermal margin due to smaller pad area; higher conduction loss in sustained 0.5 A loads | Prefer when board area is constrained beyond SOD323F and average current <300 mA |
| NSR0530HT1G | Lower VF (330–390 mV @ 500 mA); same 30 V rating; SOD-123 package (larger, 3.7 × 1.7 mm) | Better thermal dissipation (Rth(j-a) ≈ 200 K/W); higher surge rating (IFSM = 20 A) | Prefer when peak pulse current exceeds 10 A or ambient exceeds 60 °C with limited heatsinking |
Compared with RB520S-30T1G and NSR0530HT1G, PMEG3005EJ,115 delivers optimal balance of ultra-low VF, proven SOD323F manufacturability, and guarded robustness - making it ideal for cost-sensitive, high-volume consumer power management where footprint and thermal design are tightly coupled.

FAQ
What is the maximum continuous forward current rating for PMEG3005EJ,115?
The PMEG3005EJ,115 is rated for 0.5 A continuous forward current at solder point temperature ≤55 °C. This assumes FR4 PCB mounting with single-sided 1 cm² cathode copper pour. Exceeding 55 °C ambient requires linear derating per the datasheet's thermal curves.
Does PMEG3005EJ,115 have a specified reverse recovery time (trr)?
No - as a Schottky barrier diode, PMEG3005EJ,115 has no minority-carrier storage and therefore no measurable reverse recovery time. Its switching behavior is governed solely by junction capacitance (55–70 pF) and series resistance, enabling clean turn-off in high-frequency converters.
Can PMEG3005EJ,115 be used in automotive applications?
No - the PMEG3005EJ,115 is explicitly non-automotive qualified per Nexperia's revision history. It lacks AEC-Q101 qualification and automotive-grade screening. For automotive use, Nexperia recommends the PMEG3005EH,115 (Q-grade variant) instead.
What does the marking "CD" indicate on the PMEG3005EJ,115 package?
"CD" is the manufacturer's top-side marking code for PMEG3005EJ,115, per Table 4 of the datasheet. The cathode is identified by a bar adjacent to pin 1, consistent with SC-90 (SOD323F) standard orientation.
