Product details
Overview
PMEG3015EH from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 30 V reverse voltage and 1.5 A forward current, featuring ultra-low 440–550 mV forward voltage at 1.5 A and housed in the compact SOD123F surface-mount package. It serves as a low-loss unidirectional power switch in DC-to-DC converters and polarity protection circuits.
For engineers reviewing the PMEG3015EH datasheet, PMEG3015EH pinout, PMEG3015EH application, or PMEG3015EH equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance to solder point (60 K/W), reverse leakage at 30 V (≤1000 µA), and SOD123F footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to enhance ruggedness against transient overvoltage and electrostatic stress. Its low VF enables reduced conduction losses in low-voltage, high-efficiency power paths where thermal management is constrained.
The device operates with junction temperatures up to 150 °C and exhibits typical diode capacitance of 60–72 pF at 1 V reverse bias, supporting fast switching in SMPS freewheeling and synchronous rectification roles. Thermal resistance from junction to solder point is 60 K/W under specified PCB mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum blocking capability before breakdown; defines usable input range in 24 V systems. |
| Forward Current (IF) | 1.5 A continuous - Sustained conduction rating at ≤55 °C solder point temperature. |
| Forward Voltage (VF) | 440–550 mV at 1.5 A - Directly reduces power loss (0.66–0.83 W) and heat generation in conduction mode. |
| Reverse Current (IR) | 400–1000 µA at 30 V - Limits standby power loss in reverse-biased protection applications. |
| Diode Capacitance (Cd) | 60–72 pF at 1 V - Enables <10 ns switching transitions; critical for high-frequency SMPS operation. |
| Thermal Resistance (Rth(j-sp)) | 60 K/W - Quantifies junction-to-solder-point thermal path; determines temperature rise per watt under PCB-mounted conditions. |
| Junction Temperature (Tj) | 150 °C max - Sets upper thermal limit for reliable long-term operation in sealed or high-ambient environments. |
Pinout & Package
The PMEG3015EH is housed in the SOD123F plastic surface-mount package (2.6 mm × 1.6 mm × 1.1 mm body), featuring flat leads optimized for reflow soldering and space-constrained layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative output terminal; marked by bar on package; connects to load/ground side in rectification or protection configurations. |
| 2 | Anode (A) | Positive input terminal; connects to source/VIN side; current flows from Pin 2 to Pin 1 when forward biased. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF Schottky architecture | 440–550 mV @ 1.5 A - Reduces conduction loss by >30% vs. standard silicon diodes in 3.3–12 V rails. |
| Integrated guard ring | Enhances ESD robustness and transient voltage immunity - improves reliability in noisy industrial or automotive-adjacent environments. |
| SOD123F package footprint | 2.6 mm × 1.6 mm outline with flat leads - supports automated placement and high board density without tombstoning risk. |
| Low thermal resistance to solder point | 60 K/W - Enables 1.5 A operation with minimal heatsinking on standard FR4 PCBs. |
Applications
| DC-DC Converter Freewheeling | Inverse Polarity Protection |
|---|---|
Use Scenario: Used as the freewheeling diode in buck converters delivering 3.3 V/1.5 A from a 12 V input. IC Role / Device Role / Timing Role: Unidirectional current path during low-side switch off-time; recirculates inductor current. Use Value: 440 mV VF minimizes conduction loss (0.66 W), improving efficiency by ~2.1% versus 800 mV alternatives at full load. | Use Scenario: Placed in series with VCC rail to block reverse connection of external 24 V power supply. IC Role / Device Role / Timing Role: Series-blocking diode; conducts only when anode voltage exceeds cathode by >440 mV. Use Value: Low VF ensures <550 mV voltage drop during normal operation, preserving >97% of supply headroom. |
| Low-Voltage Rectification | Low-Power Standby Supply |
Use Scenario: Rectifying 5 V AC-derived signal in USB-C auxiliary power path. IC Role / Device Role / Timing Role: Half-wave rectifier converting low-amplitude AC to pulsating DC for linear regulator input. Use Value: 255–290 mV VF at 100 mA enables clean rectification of sub-500 mV signals without clipping. | Use Scenario: Providing isolated 3.3 V standby power from main 5 V rail in always-on IoT node. IC Role / Device Role / Timing Role: Reverse-blocking element preventing backfeed from standby domain into main domain. Use Value: 400–1000 µA IR at 30 V limits standby current drain to <1 µA per diode in dual-rail isolation schemes. |
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 NSR30F30NXT5G | Same 30 V/1.5 A rating; VF = 450–580 mV; SOD-123FL package (slightly longer lead form). | Identical use in polarity protection; marginally higher VF increases conduction loss by ~0.05 W at 1.5 A. | Select if legacy design uses SOD-123FL footprint or requires ON Semi's AEC-Q200 qualified variants. |
| Vishay SS13HE3/5BT | 30 V/1.3 A; VF = 450–550 mV; SOD-123 package (no flat leads; 0.9 mm height vs. 1.1 mm). | Lower IF rating restricts use to ≤1.3 A continuous; acceptable in 1.2 A DC-DC outputs with derating. | Choose for cost-sensitive consumer designs where 200 mA margin is acceptable and standard SOD-123 is preferred. |
Compared with NSR30F30NXT5G and SS13HE3/5BT, PMEG3015EH offers the lowest Rth(j-sp) (60 K/W), enabling higher sustained current on thermally constrained boards, and its SOD123F flat leads improve solder joint reliability in vibration-prone applications.

FAQ
What is the maximum allowable solder point temperature for PMEG3015EH during reflow?
The device is rated for peak reflow temperatures up to 260 °C per JEDEC J-STD-020, with a maximum solder point temperature of 260 °C for ≤30 seconds. The SOD123F package is qualified for standard lead-free reflow profiles, and thermal resistance to solder point (60 K/W) assumes proper pad layout per Figure 6 in the datasheet.
Can PMEG3015EH be used in automotive applications?
No - PMEG3015EH is explicitly designated as non-automotive qualified in the 9 October 2024 revision. It lacks AEC-Q200 qualification and has not undergone automotive-grade stress testing. For automotive use, Nexperia offers the PMEG3015EH-Q variant, which meets AEC-Q200 requirements and is separately qualified.
How does the integrated guard ring affect reliability in real-world PCB layouts?
The guard ring mitigates edge breakdown under high dv/dt or localized ESD events by distributing electric field stress away from the active junction periphery. In practice, this increases the device's robustness against transient surges up to ±8 kV HBM without parameter shift, especially in layouts with insufficient clearance near high-noise switching nodes.
Is the 1.5 A forward current rating valid at ambient temperature?
No - the 1.5 A rating applies only when the solder point temperature (Tsp) is ≤55 °C, not ambient temperature. At Tamb = 25 °C with standard FR4 mounting (1 cm² cathode pad), derating begins above ~1.1 A due to thermal resistance; actual usable current depends on PCB copper area, airflow, and adjacent heat sources.
