Product details
Overview
PMEG2010AEK,115 from NXP Semiconductors is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated for 1 A forward current and 20 V reverse voltage, featuring a typical forward voltage of 400–450 mV at 1 A, housed in a SOT346 (SC-59A) surface-mount package. It serves as a low-loss power rectification device in compact DC/DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG2010AEK,115 datasheet, PMEG2010AEK,115 pinout, PMEG2010AEK,115 application, or PMEG2010AEK,115 equivalent, key selection criteria include its ultra-low VF performance at 1 A, thermal resistance to ambient (500 K/W standard PCB), junction temperature limit of 150 °C, and validated use in space-constrained 5 V/3.3 V power rails.
Technical Context
The PMEG2010AEK,115 employs a planar MEGA Schottky structure with an integrated guard ring to suppress edge breakdown and improve surge robustness under transient reverse bias. Its low barrier height enables sub-450 mV conduction at rated current while maintaining IR ≤ 200 µA at VR = 20 V.
Thermal design relies on FR4 PCB mounting with defined copper area: Rth(j-a) is 500 K/W on standard footprint and improves to 360 K/W with 1 cm² cathode pad. The device operates across −65 °C to +150 °C ambient, with junction limited to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Current (IF) | 1 A continuous - supports full-rated output in 1 A DC/DC buck stages without derating at Tsp ≤ 55 °C |
| Reverse Voltage (VR) | 20 V - suitable for 12 V input rails with 67 % safety margin against transients |
| Forward Voltage (VF) | 400–450 mV @ IF = 1 A - reduces conduction loss to ≤450 mW, critical for >90 % efficiency targets |
| Reverse Current (IR) | ≤200 µA @ VR = 20 V - minimizes standby leakage in battery-backed or always-on systems |
| Diode Capacitance (Cd) | 55–70 pF @ VR = 5 V, 1 MHz - enables clean switching in high-frequency (>500 kHz) SMPS designs |
| Junction Temperature (Tj) | 150 °C max - allows operation in sealed enclosures or high-ambient industrial environments |
| Thermal Resistance (Rth(j-a)) | 500 K/W - defines minimum PCB copper area required for thermal compliance on standard FR4 |
Pinout & Package
Package: SOT346 (SC-59A/TO-236), 3-lead plastic surface-mount package with 1.3 mm × 2.5 mm footprint and 0.95 mm height; marked "H1" on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Input terminal for forward conduction; connects to higher-potential side of rectification path |
| 2 | Not Connected | Internally isolated; no electrical function - must remain unconnected on PCB |
| 3 | Cathode | Output terminal for forward conduction; primary thermal path to PCB via soldered tab |
Key Features
| Feature | Design Value |
|---|---|

| Ultra-low VF Schottky architecture | Delivers 400–450 mV drop at 1 A, reducing I²R losses by >40 % versus standard silicon diodes |
| SOT346 small-outline package | Enables <2.5 mm² board area usage - ideal for USB-C PD adapters and wearable power modules |
| 150 °C junction rating | Supports operation in thermally dense layouts without forced air or heatsinks |
| Low capacitance (55–70 pF) | Minimizes switching node ringing and EMI in high-frequency synchronous rectifier applications |
Applications
| USB Power Delivery Adapter | Industrial Sensor Node Power |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30 | Higher VF (520 mV typ @ 1 A), same 20 V VR, SOD-123 package (larger footprint) | Less suitable for ultra-thin portable devices due to 3.7 mm × 1.6 mm body vs. SOT346's 2.5 mm × 1.3 mm | Select RB050M-30 only if lower-cost sourcing outweighs board-area penalty and VF penalty |
| SS12 | Same SOT23-3 package but 2 A rating, VF = 500 mV typ @ 1 A, no guard ring | Higher surge vulnerability in automotive transients; requires external TVS for load-dump immunity | Choose SS12 when higher current headroom is needed and transient robustness is managed externally |
Compared with PMEG2010AEK,115, RB050M-30 trades board area and VF for cost, while SS12 sacrifices guard-ring reliability for current headroom - making PMEG2010AEK,115 optimal for space-constrained, high-reliability 1 A rectification where low VF and built-in stress protection are mandatory.

FAQ
What is the maximum continuous forward current rating for PMEG2010AEK,115?
The PMEG2010AEK,115 is rated for 1 A continuous forward current (IF) under conditions where solder point temperature (Tsp) does not exceed 55 °C. This rating assumes standard FR4 PCB mounting with single-sided copper and tin-plated traces. Exceeding this limit risks thermal runaway due to the Schottky structure's positive temperature coefficient of VF.
Does PMEG2010AEK,115 have a guard ring, and why does it matter?
Yes, the PMEG2010AEK,115 integrates a guard ring to suppress edge breakdown during reverse-bias transients. This feature directly enhances reliability in applications like automotive body control modules, where load-dump events impose repetitive 20 V reverse stress. Without the guard ring, localized electric field crowding would accelerate degradation and premature failure.
What is the typical forward voltage of PMEG2010AEK,115 at 100 mA and 1 A?
The PMEG2010AEK,115 exhibits a typical forward voltage of 265–290 mV at 100 mA and 400–450 mV at 1 A, both measured at Tamb = 25 °C. These values reflect its ultra-low VF Schottky design, enabling high-efficiency operation across light-load and full-load conditions in DC/DC converters.
Can PMEG2010AEK,115 be used in reverse polarity protection circuits?
Yes, PMEG2010AEK,115 is explicitly suited for reverse polarity protection, as confirmed in its official applications list. Its 20 V reverse voltage rating provides margin for 12 V systems, and its low 200 µA reverse leakage at 20 V ensures minimal standby power loss - critical for battery-powered sensor nodes using PMEG2010AEK,115 in series with the supply rail.
What is the thermal resistance from junction to ambient for PMEG2010AEK,115 on a standard PCB?
The thermal resistance from junction to ambient (Rth(j-a)) for PMEG2010AEK,115 is 500 K/W when mounted on a standard FR4 PCB with single-sided copper, tin-plated traces, and the manufacturer's recommended footprint. This value assumes no additional copper pour and defines the baseline thermal design requirement for natural-convection cooling.
