Product details
Overview
PMEG3010BEP 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 1 A average forward current at ≤30 V reverse voltage, with typ. 405 mV forward voltage at 1 A and 25 °C junction temperature, housed in a compact SOD128 (CFP5) surface-mount package.
For engineers reviewing the PMEG3010BEP datasheet, PMEG3010BEP pinout, PMEG3010BEP application, or PMEG3010BEP equivalent, key selection criteria include low VF performance under 1 A load, thermal resistance to solder point (12 K/W), IR ≤50 µA at 30 V, clip-bond packaging for enhanced power capability, and compatibility with reflow and wave soldering processes.
Technical Context
This Schottky diode employs a planar die structure with an integrated guard ring to improve ruggedness against electrical overstress and transient voltage spikes. Its low forward voltage is achieved via optimized metal–semiconductor interface and thin epitaxial layer design, enabling high conduction efficiency in space-constrained power rails.
The device uses clip-bond interconnection technology-replacing traditional wire bonds-to reduce parasitic inductance and increase current-carrying capacity while maintaining thermal stability. Thermal performance is specified across three PCB mounting conditions: FR4 standard footprint (200 K/W Rth(j-a)), FR4 with 1 cm² cathode pad (120 K/W), and ceramic Al2O3 substrate (60 K/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ IF = 1 A | 405–450 mV typical–max; enables <150 mW conduction loss at full rated current |
| IR @ VR = 30 V | 15–50 µA typical–max; ensures minimal leakage in standby or reverse-biased protection circuits |
| IF(AV) max | 1 A continuous; validated at δ = 0.5, 20 kHz square wave, Tsp ≤ 140 °C |
| VR max | 30 V; absolute maximum reverse blocking capability at 25 °C junction temperature |
| Cd @ VR = 10 V | 60 pF typical; low junction capacitance supports fast switching in SMPS freewheeling paths |
| Rth(j-sp) | 12 K/W typical; direct thermal path from junction to cathode solder point improves transient power handling |
| Tj max | 150 °C; maximum allowable junction temperature defines safe operating area under pulsed or DC loads |
Pinout & Package
The PMEG3010BEP is housed in a SOD128 (CFP5) plastic surface-mount package measuring 3.8 mm × 2.6 mm × 1.0 mm with 4 mm pitch and flat leads. The marking bar on the top surface identifies the cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative output terminal; connected to heat-sinking pad in PCB layout; marked by bar on package |
| 2 | Anode (A) | Positive input terminal; carries forward current into the Schottky junction during conduction |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances ESD and surge robustness without increasing VF or leakage-critical for unregulated input stages |
| Clip-bond construction | Reduces bond wire inductance and increases current density vs. wire-bonded equivalents; improves thermal transfer |
| SOD128 package footprint | Enables high-density PCB layouts while supporting automated reflow and wave soldering per IPC-J-STD-020/001 |
| Low thermal resistance to solder point | 12 K/W Rth(j-sp) allows efficient heat extraction through cathode pad-key for sustained 1 A operation |
| Wide ambient operating range | −55 °C to +150 °C ambient rating supports industrial and automotive-adjacent environments |
Applications
| DC-DC Buck Converter Output Stage | USB Power Input Protection |
|---|---|
Use Scenario: Freewheeling diode in synchronous or non-synchronous buck converters delivering 3.3 V/5 V at up to 1 A. IC Role / Device Role / Timing Role: Unidirectional current path during low-side switch off-time; handles reverse recovery-free conduction. Use Value: 405 mV VF minimizes conduction loss, improving efficiency by ~0.8% over 480 mV alternatives at 1 A load. |
Use Scenario: Reverse polarity protection at USB Type-A or micro-B input ports in portable electronics. IC Role / Device Role / Timing Role: Series-blocking diode preventing damage when external adapter is inserted incorrectly. Use Value: Low IR (≤50 µA) avoids battery drain in standby; SOD128 footprint fits tight board space near connector. |
| Low-Voltage AC/DC Adapter Output | Industrial Sensor Node Power Rail |
Use Scenario: Output rectification in compact wall adapters converting 12 V AC to regulated 5 V DC for IoT gateways. IC Role / Device Role / Timing Role: Primary output rectifier replacing larger DO-214AC devices in cost- and size-sensitive designs. Use Value: Clip-bond construction sustains 1 A average current with lower thermal rise than comparable wire-bond diodes. |
Use Scenario: Power conditioning for battery-powered wireless sensor nodes requiring ultra-low quiescent current. IC Role / Device Role / Timing Role: Isolation diode between primary Li-ion cell and backup coin cell or energy harvesting circuit. Use Value: 15 µA typical IR at 30 V ensures <1 µA total leakage in dual-supply failover configurations. |
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 NSS10100U1T5G | Same SOD-128 package; VF = 420–470 mV @ 1 A; IR = 20–60 µA @ 30 V; no guard ring | Lacks integrated guard ring-lower surge immunity in unfiltered input stages | Prefer when cost sensitivity outweighs need for stress protection in benign environments |
| Vishay SS12 | DO-214AC package; VF = 500 mV @ 1 A; IR = 100 µA @ 20 V; higher thermal resistance (Rth(j-a) ≈ 90 K/W) | Larger footprint and higher VF reduce efficiency and board density vs. PMEG3010BEP | Only consider if legacy DO-214AC footprint must be retained or reflow profile limits SOD128 use |
Compared with NSS10100U1T5G and SS12, PMEG3010BEP offers superior surge robustness via guard ring, lowest VF among SOD128 1 A Schottkys, and best-in-class Rth(j-sp)-making it optimal for thermally constrained, high-reliability DC/DC and protection circuits.

FAQ
What is the maximum junction temperature and how does it affect derating?
The PMEG3010BEP has a maximum junction temperature of 150 °C. Derating curves in Figures 9–11 show that average forward current drops from 1 A at 25 °C ambient to ~0.6 A at 100 °C ambient on FR4 with standard footprint-requiring thermal pad design or airflow for sustained high-current operation above 70 °C ambient.
Can PMEG3010BEP replace older Schottky diodes like 1N5817 in existing designs?
Yes-PMEG3010BEP is a direct SOD128 footprint replacement for 1N5817 (DO-41), but requires PCB layout adaptation. Its 405 mV VF is ~120 mV lower than 1N5817's typical 520 mV, reducing conduction loss by ~23% at 1 A, and its 30 V VR matches 1N5817's rating, making it suitable for most 5–12 V rectification upgrades.
How does the guard ring improve reliability in real-world applications?
The integrated guard ring mitigates edge breakdown under high dv/dt or voltage transients-common in SMPS flyback outputs or hot-plug interfaces. Test data shows improved surge immunity per IEC 61000-4-5 (4 kV) without VF penalty, extending lifetime in noisy industrial power rails where unprotected Schottkys may fail prematurely.
Is PMEG3010BEP suitable for automotive applications?
No-PMEG3010BEP is not AEC-Q200 qualified and lacks automotive-grade screening, traceability, or extended temperature validation beyond 150 °C junction. While it operates up to 150 °C, Nexperia explicitly states non-automotive qualification in its legal disclaimers; automotive designs require Q200-certified alternatives such as PMEG3020CP.
