Product details
Overview
PMEG3005EJF 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 portable power rails.
For engineers reviewing the PMEG3005EJF datasheet, PMEG3005EJF pinout, PMEG3005EJF application, or PMEG3005EJF equivalent, key selection criteria include ultra-low VF at low current, thermal resistance to solder point (55 K/W), cathode-marked SMD footprint compatibility, and non-automotive qualification status per revision history.
Technical Context
This MEGA-series Schottky diode uses a planar structure with integrated guard ring for robust ESD and surge stress protection. Its low VF stems from optimized metal-semiconductor interface design, enabling high efficiency in sub-1 W buck converters and battery-input circuits where conduction loss dominates.
Thermal performance is defined by two mounting conditions: Rth(j-a) = 350 K/W on standard FR4 and Rth(j-sp) = 55 K/W with 1 cm² cathode pad - critical for predicting junction temperature rise under pulsed IF = 7 A (IFRM) or IFSM = 10 A surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 500 mA | 380–430 mV - enables ≥92% efficiency in 3.3 V → 1.2 V buck stages at light-to-moderate load |
| VR | 30 V - supports input rails up to 24 V nominal with 25% derating margin |
| IR @ 30 V | 40–150 µA - limits standby power loss to <4.5 µW in always-on 3.3 V reverse-protection paths |
| Cd @ 1 V | 55–70 pF - ensures minimal switching node ringing in >1 MHz synchronous rectifiers |
| Rth(j-sp) | 55 K/W - allows 100 °C junction rise with only 5.5 W dissipation when using recommended 1 cm² cathode copper pad |
| IF(AV) max | 0.5 A continuous - rated for Tsp ≤ 55 °C ambient, requiring board-level thermal management in enclosed designs |
Pinout & Package
Encapsulated in SOD323F (SC-90), a 1.7 mm × 1.25 mm × 0.7 mm flat-lead surface-mount package with cathode indicated by a marking bar. The compact outline supports high-density PCB layouts in wearables and IoT edge nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output terminal for forward conduction; marking bar aligns with this pin for visual orientation during placement |
| 2 | Anode (A) | Input terminal; connects to higher-potential rail in rectification or reverse-protection configurations |
Key Features
| Feature | Design Value |
|---|---|
| Very low VF | 380–430 mV at 500 mA - reduces conduction loss by ~40% vs. standard Schottkys in 3.3 V systems |
| Integrated guard ring | Enhances ruggedness against ESD (IEC 61000-4-2 Level 4) and transient overvoltage without external clamping |
| Flat lead SMD package | SOD323F footprint enables 0.3 mm pitch routing and eliminates tombstoning risk in reflow assembly |
| Low Cd | 55–70 pF at 1 V - minimizes capacitive loading on high-frequency switch nodes in DC/DC controllers |
Applications
| USB Power Delivery Input Protection | Low-Voltage DC/DC Converter Output Rectification |
|---|---|
Use Scenario: Protects 5 V/9 V/15 V USB PD input rails from reverse connection in portable chargers and dongles. IC Role / Device Role / Timing Role: Unidirectional blocking element placed between connector and primary buck controller. Use Value: 380 mV VF limits voltage drop to <0.4% of 5 V rail, preserving PD negotiation headroom while blocking −5 V faults. |
Use Scenario: Synchronous rectifier replacement in 1.2 V/1.8 V output stages of PMICs powering microcontrollers. IC Role / Device Role / Timing Role: Low-loss freewheeling path during high-side FET off-time in 2–3 MHz buck converters. Use Value: 70 pF Cd avoids resonance with 100 nH parasitic inductance, preventing 100+ MHz ringing that disrupts feedback stability. |
| Battery Backup Switchover | Industrial Sensor Node Reverse Polarity Guard |
Use Scenario: OR-ing diode between Li-ion battery (3.0–4.2 V) and main 3.3 V system rail in always-on monitoring devices. IC Role / Device Role / Timing Role: Automatic power source selector ensuring seamless transition during AC loss. Use Value: 150 µA IR at 30 V reverse bias draws <0.5 µA from backup battery in storage, extending shelf life beyond 10 years. |
Use Scenario: Input protection for 24 V-powered field transmitters exposed to accidental wiring reversal in factory automation. IC Role / Device Role / Timing Role: First-line defense against −24 V transients before LDO or signal conditioner ICs. Use Value: Guard ring withstands 10 A IFSM surges per IEC 61000-4-5, eliminating need for upstream TVS in Class A installations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0530HT1G | VF = 450 mV @ 500 mA; VR = 30 V; same SOD-323 package but no guard ring | Lacks integrated stress protection - requires external TVS for IEC 61000-4-5 compliance | Prefer when cost sensitivity outweighs surge robustness requirements |
| Vishay SS32HE3/5BT | VF = 500 mV @ 500 mA; VR = 20 V; SMA package (larger footprint, higher Rth) | Lower VR rating restricts use to ≤12 V systems; 2× larger PCB area needed | Select only if existing SMA layout prohibits SOD323F redesign |
Compared with NSR0530HT1G and SS32HE3/5BT, PMEG3005EJF delivers the lowest VF in its class with built-in guard ring - making it optimal for space-limited, high-reliability 24 V industrial inputs and USB PD interfaces where thermal and surge margins are constrained.

FAQ
Is PMEG3005EJF qualified for automotive applications?
No. Per Revision History Table 8, PMEG3005EJF was explicitly changed to non-automotive qualification in the October 2022 release. Automotive-grade alternatives (e.g., PMEG3005EJ-Q) are listed on Nexperia's website and feature extended temperature range (−40 °C to 150 °C) and AEC-Q101 testing.
What is the maximum allowable PCB copper area for the cathode pad to achieve Rth(j-sp) = 55 K/W?
The datasheet specifies Rth(j-sp) = 55 K/W applies only when the cathode pad is 1 cm² of single-sided, tin-plated copper on FR4. Using smaller pads increases thermal resistance linearly - e.g., a 0.25 cm² pad raises Rth(j-sp) to ~110 K/W, limiting safe continuous current to ~0.25 A at 55 °C ambient.
Can PMEG3005EJF be used in place of a 1N5817 in a 5 V supply?
Yes, with caveats: PMEG3005EJF offers lower VF (380 mV vs. 450 mV) and smaller size, but its 30 V VR matches 1N5817's 20 V rating only with 50% margin. It is not a direct drop-in due to SOD323F vs. DO-41 footprint - PCB layout revision is required, and reverse leakage (150 µA) is higher than 1N5817's typical 10 µA.
Does the marking code 'CD' correspond exclusively to PMEG3005EJF?
Yes. Table 4 confirms 'CD' is the unique marking code for PMEG3005EJF per Nexperia's ordering information. No other type number shares this marking, and it appears adjacent to the cathode bar on the device body - enabling unambiguous visual identification during inspection and rework.
