Product details
Overview
PMEG3005EB,115 from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated for 0.5 A forward current and 30 V reverse voltage, featuring a typical forward voltage of 430 mV at 500 mA and ultra-low capacitance (24–30 pF). It operates in DC-to-DC converters, reverse polarity protection circuits, and low-power supply rails where minimal conduction loss and fast switching are critical.
For engineers reviewing the PMEG3005EB,115 datasheet, PMEG3005EB,115 pinout, PMEG3005EB,115 application, or PMEG3005EB,115 equivalent, key selection criteria include verified VF at 500 mA, thermal resistance to solder point (75 K/W), SOD523 package footprint compatibility, and IR leakage under 500 µA at 30 V.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low VF stems from optimized metal-semiconductor interface design, enabling high efficiency in low-voltage (<5 V) power paths.
Thermal performance is defined by junction-to-solder-point resistance (75 K/W), reflecting direct heat transfer via the cathode tab-critical for PCB-level thermal management in space-constrained designs. Reverse recovery is effectively zero due to majority-carrier conduction, eliminating switching tail current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward current (IF) | 0.5 A continuous - supports sustained operation in compact DC/DC output stages without derating at Tsp ≤ 55 °C |
| Reverse voltage (VR) | 30 V maximum - suitable for 24 V nominal systems with margin for transients and ripple |
| Forward voltage (VF) | 430 mV typ. at 500 mA - reduces conduction loss to <215 mW, enabling >95% efficiency in 3.3 V buck outputs |
| Reverse current (IR) | 70 µA typ. at 30 V - ensures minimal standby leakage in battery-backed or always-on circuits |
| Diode capacitance (Cd) | 24 pF typ. at 1 V - enables clean high-frequency switching (>1 MHz) with negligible AC coupling or ringing |
| Thermal resistance (Rth(j-sp)) | 75 K/W - allows direct thermal path from junction to PCB copper, supporting 310 mW total dissipation on standard FR4 |
| Junction temperature (Tj) | 150 °C max - defines safe operating limit for thermal design in sealed or high-ambient environments |
Pinout & Package
Encapsulated in the SOD523 (SC-79) ultra-small surface-mount package (1.2 mm × 0.8 mm × 0.6 mm), this two-terminal device uses a standardized footprint with cathode marked by a bar on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to load ground or return path; marking bar identifies this terminal; primary heat extraction path via cathode tab |
| 2 (A) | Anode | Connected to input or switched node; carries full forward current; no thermal relief required on PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge breakdown under voltage transients, improving long-term reliability in unregulated input rails |
| Ultra-low VF at rated current | 430 mV typ. @ 500 mA - directly lowers I²R losses and thermal rise in high-duty-cycle applications |
| SOD523 package size | 1.2 mm × 0.8 mm footprint - enables placement in dense power IC layouts, including near PMICs and microcontrollers |
| Low reverse leakage | 70 µA typ. @ 30 V - minimizes quiescent drain in always-on subsystems such as real-time clocks or sensor biasing |
| Fast majority-carrier switching | No minority-carrier storage - eliminates reverse recovery time, preventing shoot-through in synchronous rectifiers |
Applications
| USB Power Delivery Input Protection | IoT Sensor Node Power Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G | Higher VF (490 mV typ. @ 500 mA); same 30 V VR; SOD-523 package | Acceptable where 60 mV higher conduction loss is tolerable for cost-sensitive volume production | Select if BOM consolidation with ON Semiconductor portfolio is prioritized over minimal VF |
| SS12 | Higher IF (1 A); larger SOD-123 package; VF = 500 mV typ. @ 1 A | Required only when >0.5 A average current or higher surge capability (IFSM = 25 A) is needed | Choose only when board space permits larger footprint and thermal mass justifies higher current rating |
Compared with RB520S-30T1G and SS12, PMEG3005EB,115 delivers the lowest VF in SOD523, making it optimal for space-constrained, low-voltage, high-efficiency applications where every millivolt of drop impacts system runtime or thermal budget.

FAQ
What is the maximum allowable soldering temperature profile for PMEG3005EB,115?
The device complies with JEDEC J-STD-020D reflow requirements for MSL1. Peak temperature must not exceed 260 °C for ≤ 30 seconds, with ramp-up rate ≤ 3 °C/s and ramp-down rate ≤ 6 °C/s. The recommended footprint matches Figure 6 in the datasheet: 0.5 mm wide × 1.4 mm long solder lands with 0.4 mm solder resist opening.
Does PMEG3005EB,115 have automotive qualification?
No. PMEG3005EB,115 is not AEC-Q200 qualified and is intended for industrial, consumer, and computing applications. Nexperia explicitly states in its legal disclaimers that non-automotive qualified products are unsuitable for safety-critical or automotive use without additional customer validation and risk assumption.
How does the guard ring affect long-term reliability under repetitive voltage stress?
The integrated guard ring redistributes electric field intensity at the die edge, reducing localized avalanche initiation. This extends operational lifetime under repeated 30 V reverse bias with fast dv/dt transients, as confirmed by accelerated life testing per JESD22-A108 and demonstrated in Nexperia's reliability reports for SOD523 Schottky series.
Can PMEG3005EB,115 replace a standard PN diode in a 5 V supply rail?
Yes-provided VR ≥ 30 V and IF ≤ 0.5 A. Its 430 mV VF cuts conduction loss by ~65% versus a typical 1N4148 (VF ≈ 1.2 V @ 10 mA), significantly reducing self-heating. However, reverse leakage (70 µA vs. 25 nA for 1N4148) must be evaluated in ultra-low-quiescent-current designs.
