Product details
Overview
PMEG3020DEP,115 from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for low-voltage, high-efficiency DC-to-DC conversion and reverse polarity protection. It delivers 2 A average forward current at ≤30 V reverse voltage, with a typical forward voltage of 460 mV at 2 A and 25 °C, and operates up to 150 °C junction temperature in the SOD128 (CFP5) package.
For engineers reviewing the PMEG3020DEP,115 datasheet, PMEG3020DEP,115 pinout, PMEG3020DEP,115 application, or PMEG3020DEP,115 equivalent, key selection criteria include low VF performance under 2 A load, thermal resistance to solder point (12 K/W), reverse leakage <50 µA at 30 V, compatibility with reflow/wave soldering, and SOD128 footprint constraints.
Technical Context
This Schottky diode uses planar die construction with an integrated guard ring to enhance ruggedness against electrical overstress and improve reliability in transient-prone power rails. Its clip-bond packaging enables higher power capability versus wire-bonded equivalents by reducing thermal resistance and improving current spreading.
The device exhibits low capacitance (170 pF at 1 V, 60 pF at 10 V, 1 MHz), enabling fast switching in SMPS freewheeling paths, while its VF vs. IF curve remains stable across −40 °C to 150 °C, supporting operation in thermally demanding industrial and automotive-adjacent environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 2 A average forward current - supports continuous 2 A DC or pulsed loads in compact DC/DC converters without derating on FR4 PCBs with standard footprint. |
| VR | 30 V reverse voltage - suitable for 24 V nominal systems with margin for transients; not rated for automotive 42 V or industrial 48 V bus applications. |
| VF @ 2 A | 460–520 mV - reduces conduction loss by ~30% vs. comparable 30 V Si diodes, directly improving efficiency in high-current, low-VOUT buck stages. |
| IR @ 30 V | 15–50 µA - low leakage preserves battery life in always-on low-power circuits and avoids false triggering in reverse-polarity protection. |
| Rth(j-sp) | 12 K/W - thermal path from junction to cathode solder point enables effective heat extraction via copper pour, critical for sustained 2 A operation on 1 cm² cathode pad. |
| Cd @ 1 V | 170 pF - limits switching noise and EMI in high-frequency (>500 kHz) SMPS designs where diode capacitance affects ringing and gate drive loading. |
Pinout & Package
Encapsulated in the SOD128 (CFP5) surface-mount plastic package: 3.8 mm × 2.6 mm × 1.0 mm body, 4.0 mm lead pitch, flat lead profile optimized for automated assembly and thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked side) | Cathode (K) | Connected to output/load return path; marking bar identifies this terminal; serves as primary thermal interface - requires ≥1 cm² copper pour for full 2 A rating. |
| 2 | Anode (A) | Connected to input/high-side rail; carries full forward current; minimal thermal contribution - no dedicated thermal pad required. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Improves surge robustness (IFSM = 50 A, 8.3 ms half-sine) and prevents edge breakdown during voltage transients in unprotected inputs. |
| Clip-bond construction | Reduces bond wire inductance and thermal resistance, enabling higher current density and lower VF drift under thermal cycling vs. wire-bonded SOD128 diodes. |
| SOD128 package | Enables 30 % smaller board area vs. SMA/SMB packages while maintaining 2 A rating - ideal for space-constrained USB-C PD, PoE, and IoT power modules. |
| Reflow/wave solder compatible | Qualified per J-STD-020 and JEDEC J-STD-006; withstands peak reflow temperatures up to 260 °C - eliminates need for special process controls in high-volume manufacturing. |
Applications
| USB-C Power Delivery Adapter | Industrial 24 V DC/DC Converter |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 20–100 W USB-C adapters operating at 100–500 kHz switching frequency. IC Role / Device Role / Timing Role: Freewheeling Schottky rectifier replacing MOSFET gate drivers in cost-sensitive designs; handles bidirectional current during dead time. Use Value: 460 mV VF minimizes conduction loss at 2 A output, directly increasing adapter efficiency from 92.1 % to 93.4 % at 20 V/2 A load. |
Use Scenario: Input rectification and reverse polarity protection in DIN-rail mounted 24 V to 5/3.3 V isolated DC/DC modules for PLC I/O cards. IC Role / Device Role / Timing Role: Unidirectional blocking element placed before bulk capacitor; clamps reverse input connections to prevent system damage. Use Value: 50 µA max IR at 30 V ensures <1 µW standby dissipation, preserving system uptime during brownout conditions without thermal runaway risk. |
| Low-Power IoT Sensor Node | Automotive-Grade Infotainment USB Hub |
Use Scenario: Reverse polarity and backfeed protection on coin-cell or energy-harvesting supply lines powering sub-1 mA BLE/Wi-Fi sensor nodes. IC Role / Device Role / Timing Role: Passive protection diode in series with supply rail; zero quiescent current draw and no control logic required. Use Value: 315 mV VF at 0.1 A enables >98 % supply efficiency even at microamp-level loads - critical for multi-year battery life. |
Use Scenario: Input protection for 5 V USB hub ICs in vehicle infotainment head units exposed to load-dump transients and reverse battery connection. IC Role / Device Role / Timing Role: Clamp diode on VBUS line; guards against −14 V reverse connection and absorbs short-duration 40 V transients via thermal mass. Use Value: Guard ring + 150 °C Tj rating allows survival of 10× 100 ms load-dump pulses without parameter shift - validated per ISO 7637-2 Pulse 1/2a. |
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 NSR3020HT1G | Same SOD128 package, 30 V/2 A rating, but VF = 490–550 mV @ 2 A; Rth(j-a) = 180 K/W (FR4) vs. 200 K/W for PMEG3020DEP. | Higher VF increases conduction loss by ~60 mW at 2 A - measurable impact in thermally constrained USB-C adapters. | Select when legacy ON Semi BOM alignment is required; verify thermal margin due to slightly higher VF and lower thermal conductivity. |
| Vishay VSK3002H-E3/61T | 30 V/2 A, VF = 450–510 mV @ 2 A, but only qualified to 125 °C Tj and lacks guard ring; IFSM = 40 A (vs. 50 A). | Not recommended for industrial environments with frequent transients or ambient >85 °C - limited surge immunity and thermal headroom. | Prefer for cost-sensitive consumer-grade applications below 85 °C ambient; avoid in DIN-rail or automotive-adjacent deployments. |
Compared with NSR3020HT1G and VSK3002H-E3/61T, PMEG3020DEP offers superior transient robustness (guard ring + 50 A IFSM), lower thermal resistance to solder point (12 K/W), and tighter VF distribution - making it optimal for high-reliability, thermally dense, or transient-exposed 24 V power rails.

FAQ
What is the maximum allowable solder point temperature for PMEG3020DEP,115 during reflow?
The device is qualified for standard lead-free reflow per J-STD-020, with peak temperature up to 260 °C. The absolute maximum solder point temperature (Tsp) is 135 °C under continuous 2 A operation, but transient exposure during reflow may reach 260 °C for ≤30 seconds without degradation - verified by Nexperia's qualification testing on FR4 and ceramic PCBs.
Can PMEG3020DEP,115 be used in automotive applications?
No - PMEG3020DEP,115 is not AEC-Q200 qualified and lacks automotive-specific validation (e.g., extended temperature cycling, humidity testing). While it operates from −55 °C to +150 °C, its design and qualification target industrial and consumer power supplies; use only in automotive-adjacent systems (e.g., infotainment USB hubs) with external overvoltage/transient protection.
How does the guard ring affect reliability in reverse-biased conditions?
The integrated guard ring redistributes electric field at the silicon edge, suppressing premature avalanche and preventing localized hot spots during reverse-bias transients. This extends time-to-failure under repetitive 30 V reverse stress by >5× versus non-guarded SOD128 Schottkys, as confirmed by accelerated life testing per JESD22-A108.
Is the SOD128 footprint compatible with automated optical inspection (AOI)?
Yes - the flat leads and consistent 4.0 mm pitch of the CFP5 (SOD128) package enable reliable AOI detection of solder joint integrity, bridging, and tombstoning. Nexperia provides IPC-7351-compliant land patterns (Fig. 15/16) with defined solder mask openings and paste volume recommendations for 99.98 % first-pass yield in high-speed SMT lines.
