Product details
Overview
PMEG3015EH-QX 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, housed in an AEC-Q101-qualified SOD123F package for automotive-grade low-voltage rectification and DC-to-DC conversion.
For engineers reviewing the PMEG3015EH-QX datasheet, PMEG3015EH-QX pinout, PMEG3015EH-QX application, or PMEG3015EH-QX equivalent, key selection criteria include its ultra-low VF performance at high current, thermal resistance (Rth(j-sp) = 60 K/W), AEC-Q101 qualification, and cathode-marked SOD123F footprint compatibility in space-constrained power rails.
Technical Context
This Schottky diode employs a planar junction structure with integrated guard ring to suppress edge breakdown and improve robustness under transient stress. Its ultra-low forward voltage stems from optimized metal-semiconductor interface design, enabling high conduction efficiency at low voltages without compromising reverse leakage.
Thermal performance is defined by two distinct mounting conditions: Rth(j-a) = 330 K/W on standard FR4 and Rth(j-sp) = 60 K/W with 1 cm² cathode pad-enabling accurate junction temperature estimation in both ambient-limited and solder-point-limited layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V maximum - defines maximum blocking capability in reverse-biased applications like polarity protection or freewheeling paths. |
| Forward Current (IF) | 1.5 A continuous at Tsp ≤ 55 °C - sets usable DC load current limit before thermal derating begins. |
| Forward Voltage (VF) | 440–550 mV at IF = 1.5 A - directly reduces conduction loss in high-efficiency buck converters and OR-ing circuits. |
| Reverse Current (IR) | 60–150 µA at VR = 10 V, 25 °C - low leakage preserves battery life in always-on low-power systems. |
| Diode Capacitance (Cd) | 60–72 pF at VR = 1 V, 1 MHz - minimizes switching node ringing and EMI in high-frequency SMPS designs. |
| Junction Temperature (Tj) | 150 °C maximum - supports operation in under-hood automotive environments with appropriate PCB thermal design. |
| Thermal Resistance (Rth(j-sp)) | 60 K/W - enables precise thermal modeling when cathode pad area is controlled per datasheet layout guidance. |
Pinout & Package
Encapsulated in the compact, flat-lead SOD123F surface-mount plastic package (2.6 mm × 1.6 mm × 1.1 mm), this device uses a 2-terminal configuration with cathode identified by a marking bar on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to lower-potential side of circuit; marking bar identifies this terminal for correct PCB orientation and polarity-sensitive placement. |
| 2 | Anode (A) | Connected to higher-potential side; serves as input for forward conduction path in rectification or freewheeling configurations. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics requiring extended temperature and reliability compliance. |
| Ultra-low VF (440–550 mV @ 1.5 A) | Reduces forward power loss by >30% vs. standard Schottkys, improving efficiency in 3.3 V/5 V DC-DC outputs and battery-fed systems. |
| Integrated guard ring | Suppresses edge-related avalanche and improves voltage stability under fast transients, enhancing surge immunity in noisy automotive power rails. |
| SOD123F footprint | Enables high-density layout with 2.6 mm × 1.6 mm body and standardized reflow-compatible solder land pattern per Figure 6. |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Input Protection |
|---|---|
Use Scenario: Reverse polarity protection at 12 V supply input of BCM modules exposed to jump-start or service misconnection events. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed in series with main power rail to prevent damage from −12 V transients. Use Value: 30 V VR rating and AEC-Q101 qualification ensure survivability across ISO 16750-2 test pulses; low VF minimizes voltage drop during normal operation. |
Use Scenario: OR-ing diode in dual-input USB-C PD front-end to select between adapter and battery sources without backfeed. IC Role / Device Role / Timing Role: Low-loss forward conduction path with fast recovery and minimal capacitance to avoid signal integrity issues on CC lines. Use Value: 60–72 pF Cd and sub-550 mV VF enable clean source handover while maintaining PD negotiation timing margins. |
| Industrial 24 V DC-DC Converter Output Stage | Smart Meter Battery Backup Circuit |
Use Scenario: Synchronous rectifier replacement in isolated flyback secondary side operating at 24 V output and 1.2 A load. IC Role / Device Role / Timing Role: Freewheeling diode conducting during MOSFET off-time to maintain continuous inductor current. Use Value: 1.5 A IF rating and 60 K/W Rth(j-sp) allow stable operation at full load without heatsink, reducing BOM count and board area. |
Use Scenario: Isolation diode between primary Li-ion battery and supercapacitor backup rail in utility meter with 10-year field life requirement. IC Role / Device Role / Timing Role: Leakage-suppressing blocking element preventing self-discharge of backup energy storage. Use Value: 60–150 µA IR at 10 V ensures <0.1% monthly self-discharge rate, extending maintenance-free operation beyond specification. |
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 but VF = 490–600 mV at 1.5 A; Rth(j-a) = 290 K/W (SOD-123). | Lacks AEC-Q101 qualification; suitable for industrial/commercial but not automotive-critical use. | Select when cost sensitivity outweighs automotive qualification and slightly higher VF is acceptable. |
| Vishay SS13HE3/5BT | 30 V/1.3 A; VF = 450–550 mV at 1.3 A; SOD-123 package; no AEC-Q101 claim in datasheet. | Lower IF rating limits use in sustained 1.5 A loads; unqualified for automotive stress testing. | Prefer only in non-automotive, thermally relaxed designs where 200 mA margin is acceptable. |
Compared with NSR30F30NXT5G and SS13HE3/5BT, PMEG3015EH-QX delivers tighter VF consistency, guaranteed AEC-Q101 compliance, and superior thermal resistance to solder point-making it the sole choice for automotive power rail protection and high-reliability industrial converters.

FAQ
What is the maximum allowable junction temperature for PMEG3015EH-QX?
The absolute maximum junction temperature is 150 °C, as specified in Table 5 (Limiting values). Operation above this temperature risks permanent degradation. Thermal design must ensure Tj remains within this limit using the provided Rth(j-sp) = 60 K/W value and measured solder point temperature under worst-case load and ambient conditions.
Is PMEG3015EH-QX compatible with lead-free reflow soldering profiles?
Yes-PMEG3015EH-QX is qualified for lead-free reflow per J-STD-020, with peak temperature tolerance up to 260 °C. The recommended reflow profile aligns with JEDEC Level 1 moisture sensitivity, and the SOD123F package outline in Figure 5 specifies exact solder land dimensions for reliable joint formation.
How does the integrated guard ring affect electrical performance?
The guard ring mitigates electric field crowding at the silicon periphery, raising the effective reverse breakdown voltage margin and improving robustness against ESD and load dump transients. It does not alter nominal VR (30 V) or VF but enhances long-term reliability in automotive environments where voltage spikes exceed steady-state ratings.
Can PMEG3015EH-QX be used in synchronous rectification topologies?
No-it is a passive Schottky rectifier, not a synchronous rectifier controller or MOSFET driver. However, it serves as a high-efficiency replacement for standard diodes in non-synchronous topologies (e.g., flyback, boost) where gate drive complexity must be avoided and ultra-low VF is prioritized over zero-voltage switching.
