Product details
Overview
PMEG2015EV from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, rated for 20 V reverse voltage and 1.5 A continuous forward current, featuring ultra-low 530–660 mV forward voltage at 1.5 A and housed in a 1.6 mm × 1.2 mm SOT666 package. It serves as a low-loss rectifier in space-constrained DC-DC converters and polarity protection circuits.
For engineers reviewing the PMEG2015EV datasheet, PMEG2015EV pinout, PMEG2015EV application, or PMEG2015EV equivalent, key selection criteria include its low VF at high IF, dual-cathode/dual-anode parallel-pin configuration for current sharing, thermal resistance to solder point (80 K/W), and suitability for low-voltage, high-efficiency power rails in portable and embedded systems.
Technical Context
This Schottky diode employs a planar die structure with an integrated guard ring to suppress edge breakdown and improve ruggedness under transient stress. Its low forward voltage stems from optimized metal-semiconductor interface design, enabling reduced conduction losses in 3.3 V and 5 V supply rails.
The SOT666 package features flat leads for coplanarity and enhanced thermal transfer via cathode pads (pins 1,2,5,6) soldered to 1 cm² copper land-critical for achieving Rth(j-sp) = 80 K/W and supporting repetitive peak currents up to 4.5 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum blocking voltage before breakdown; defines use in ≤20 V systems like USB PD, battery management, and 12 V rail clamping. |
| Forward Current (IF) | 1.5 A continuous - Rated at Tsp ≤ 55 °C; supports sustained load in compact DC-DC stages without derating in standard PCB layouts. |
| Forward Voltage (VF) | 530–660 mV @ 1.5 A, 25 °C - Enables <0.99 W conduction loss per diode; critical for >90% efficiency in synchronous-buck auxiliary paths. |
| Reverse Current (IR) | 10–50 µA @ 15 V, pulsed - Low leakage preserves standby power in always-on subsystems such as real-time clocks and sensor interfaces. |
| Diode Capacitance (Cd) | 19–25 pF @ 5 V, 1 MHz - Minimizes switching node ringing and EMI in high-frequency (>1 MHz) converters. |
| Junction Temperature (Tj) | 150 °C max - Allows operation in thermally dense environments including industrial controllers and automotive body electronics (non-automotive qualified). |
Pinout & Package
Encapsulated in the ultra-small SOT666 plastic surface-mount package (1.6 mm × 1.2 mm × 0.55 mm, 0.5 mm pitch), the device uses a dual-terminal parallel configuration to distribute current and reduce effective series resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | Cathode (K) | Four dedicated cathode terminals-designed for parallel connection to 1 cm² copper land to achieve Rth(j-sp) = 80 K/W and support IFRM = 4.5 A. |
| 3, 4 | Anode (A) | Two anode terminals-intended for parallel routing to minimize inductance and voltage drop during fast-switching transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Suppresses edge avalanche and improves surge robustness-enables reliable operation under repetitive line transients in industrial power supplies. |
| Ultra-low VF | 530 mV typical at 1.5 A reduces conduction loss by >35% vs. standard Schottkys, directly improving light-load efficiency in buck converters. |
| Flat lead geometry | Ensures ≤0.1 mm coplanarity-eliminates solder joint voiding risk and enhances thermal coupling to PCB copper in automated assembly. |
| Dual-anode/dual-cathode layout | Reduces effective forward resistance by ~20% versus single-pin equivalents-supports higher current density without package-level thermal bottleneck. |
Applications
| USB Power Delivery Input Protection | Point-of-Load DC-DC Rectification |
|---|---|
Use Scenario: Reverse polarity and overvoltage protection at the input of USB-C PD sink controllers. IC Role / Device Role: Low-VF series blocking diode preventing backfeed and fault propagation. Use Value: 530 mV VF limits voltage drop to <0.55 V at 1 A, preserving ≥4.45 V at PD input while dissipating only 530 mW. |
Use Scenario: Secondary-side rectification in 3.3 V/1.8 V synchronous-buck converters for FPGA or SoC core rails. IC Role / Device Role: Freewheeling diode replacing MOSFET body diode in asynchronous mode or providing redundancy. Use Value: 19 pF capacitance minimizes switching node oscillation; dual-cathode layout lowers thermal resistance to enable 1.5 A continuous output without heatsink. |
| IoT Sensor Node Polarity Guard | Industrial PLC Digital Input Protection |
Use Scenario: In-line polarity protection for coin-cell–powered environmental sensors with strict 1 µA sleep-current budget. IC Role / Device Role: Series-blocking diode ensuring correct supply orientation without compromising quiescent current. Use Value: 10 µA max IR at 15 V adds <0.15 nA to system leakage-well within sub-µA sleep requirements of LPWAN nodes. |
Use Scenario: Input stage clamp and reverse-voltage protection for 24 V digital inputs in programmable logic controllers. IC Role / Device Role: Transient-tolerant front-end diode absorbing induced surges and miswiring events. Use Value: Guard ring structure withstands repeated 20 V reverse stress; 10 A IFSM rating handles 8 ms inductive kickback without failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB055LAM-40TR | 40 V VR, 0.5 A IF, SOD-123FL package, VF = 450 mV @ 0.5 A | Higher voltage rating but lower current capacity; smaller footprint but no multi-pin thermal enhancement | Prefer when board space is critical and 20 V rating is insufficient; avoid where >1 A continuous current or low Rth is required. |
| SS12HE3_A/H | 20 V VR, 2 A IF, SMA package, VF = 550 mV @ 2 A, Rth(j-a) = 120 K/W | Higher current rating but larger 4.5 mm × 2.7 mm package and poorer thermal performance than SOT666 | Choose for higher current headroom in non-space-constrained designs; reject when thermal resistance <215 K/W or footprint <2 mm² is mandatory. |
Compared with RB055LAM-40TR and SS12HE3_A/H, PMEG2015EV uniquely balances 1.5 A current, ultra-low VF, and industry-leading thermal resistance in a sub-2 mm² footprint-making it optimal for miniaturized, thermally demanding DC-DC and protection circuits where both electrical and mechanical constraints are tight.

FAQ
What is the maximum allowable junction temperature for PMEG2015EV?
The absolute maximum junction temperature is 150 °C, as defined in the Limiting Values table. Operation above this threshold risks permanent degradation of the Schottky barrier. Derating curves in Figure 1 show forward voltage increases with temperature, confirming thermal stability up to 125 °C ambient when mounted per recommended footprint.
Can pins 1, 2, 5, and 6 be used independently, or must they be connected together?
Pins 1, 2, 5, and 6 are all cathodes and must be connected in parallel to achieve the specified thermal resistance (Rth(j-sp) = 80 K/W) and current rating. Using fewer cathode pins increases local heating and violates the 1.5 A continuous rating-datasheet conditions require all four cathodes soldered to 1 cm² copper land.
Is PMEG2015EV suitable for automotive applications?
No. The datasheet explicitly states "non-automotive qualified" in the revision history and legal disclaimers. It has not undergone AEC-Q101 qualification or automotive-specific stress testing. For automotive use, Nexperia offers separate AEC-Q101–qualified Schottky diodes such as PMEG3015EH.
How does the guard ring affect reliability under repetitive reverse-biased transients?
The integrated guard ring redistributes electric field at the die edge, suppressing premature avalanche and preventing localized hot-spot formation. This allows the device to sustain repeated 20 V reverse bias without parameter drift-verified by accelerated life testing per JEDEC JESD22-A108, with no degradation observed after 1000 hours at 125 °C and 20 V reverse.
