Product details
Overview
PMEG4005AEV from Nexperia is a 40 V, 0.5 A planar Schottky barrier rectifier in SOT666 package, featuring integrated guard ring for stress protection and ultra-low forward voltage (420–470 mV at 500 mA). It serves as a low-loss unidirectional current path in compact DC/DC converters, reverse polarity protection circuits, and low-voltage rectification stages where thermal efficiency and space constraints are critical.
For engineers reviewing the PMEG4005AEV datasheet, PMEG4005AEV pinout, PMEG4005AEV application, or PMEG4005AEV equivalent, key selection criteria include its pulsed reverse current (≤100 µA at 40 V), junction-to-solder-point thermal resistance (80 K/W), dual-anode/dual-cathode parallel-pin configuration, and suitability for high-efficiency, low-power embedded power rails.
Technical Context
This Schottky diode uses a planar MEGA (Maximum Efficiency General Application) structure with an integrated guard ring to suppress edge breakdown under transient stress. Its low VF stems from optimized metal-semiconductor interface and thin epitaxial layer design, enabling operation at junction temperatures up to 150 °C without thermal runaway when reverse losses are managed.
The SOT666 package supports parallel connection of pins 3 & 4 (anode) and pins 1, 2, 5 & 6 (cathode), enabling 3.5 A repetitive peak forward current (IFRM) and 10 A non-repetitive surge (IFSM) under defined pulse conditions - critical for input-stage clamping and hold-up capacitor charging in portable power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V maximum - defines safe blocking capability in 3.3 V/5 V/12 V rail clamping and reverse-battery protection circuits. |
| Forward Voltage (VF) | 420–470 mV at 500 mA - reduces conduction loss by >30% vs. standard silicon diodes, directly improving DC/DC converter efficiency. |
| Reverse Current (IR) | 30–100 µA at 40 V - low leakage preserves battery life in always-on low-power systems and enables reliable voltage clamping. |
| Diode Capacitance (Cd) | 43–50 pF at 1 V - minimizes switching noise and EMI in high-frequency (>1 MHz) buck converters and load-switching applications. |
| Junction-to-Solder-Point Rth | 80 K/W - enables effective heat extraction via cathode tab soldering, supporting continuous 0.5 A operation on minimal PCB copper area. |
| Surge Current (IFSM) | 10 A (8 ms square wave) - withstands inrush currents during hot-plug events and capacitor pre-charge transients without degradation. |
Pinout & Package
Encapsulated in the ultra-small SOT666 plastic package (1.6 mm × 1.2 mm × 0.55 mm, 0.5 mm pitch), this device features six terminals with internal parallel anode and cathode connections for enhanced current handling and thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | K (Cathode) | Internally tied cathode terminals - enable multi-point PCB anchoring and lower effective thermal resistance to board. |
| 3, 4 | A (Anode) | Internally tied anode terminals - support parallel routing to reduce trace inductance and distribute current in high-dI/dt paths. |
Key Features
| Feature | Design Value |
|---|---|
| Very low forward voltage | 420–470 mV @ 500 mA - cuts conduction loss by ~65% versus 1N5819, extending battery runtime in wearables and IoT sensors. |
| Integrated guard ring | Edge termination structure - prevents premature avalanche at junction periphery, ensuring stable 40 V blocking under ESD and line-transient stress. |
| Ultra-small SMD package | SOT666 footprint (1.6 × 1.2 mm) - saves >50% board area vs. SOD-123, enabling dense power management in space-constrained modules. |
| High surge current rating | 10 A IFSM (8 ms) - sustains repeated hot-swap events in USB-C PD and industrial fieldbus interfaces without derating. |
Applications
| USB Power Delivery Input Protection | Wearable Device Battery Charging |
|---|---|
Use Scenario: Prevents reverse current flow and clamps voltage spikes during USB-C plug/unplug cycles in portable medical monitors. IC Role / Device Role / Timing Role: Reverse polarity protector and transient voltage clamp placed between USB-C receptacle and buck converter input. Use Value: 420 mV VF minimizes voltage drop across protection path, preserving ≥4.75 V input to downstream regulator even at 500 mA load. |

IC Role / Device Role / Timing Role: Transient voltage suppressor connected anode-to-ground, limiting negative excursions to −0.47 V. Use Value: Guard ring structure maintains 40 V VR rating under 2 kV ESD contact discharge, preventing latch-up in adjacent analog front-end ICs. |
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 | 30 V VR, 0.5 A IF, SOD-523 package, VF = 450 mV @ 500 mA | Limited to ≤30 V systems; smaller package but no guard ring; higher Rth(j-a) = 450 K/W | Select only if system VR < 30 V and board space is more constrained than thermal budget. |
| SS14 | 40 V VR, 1 A IF, SMA package, VF = 500 mV @ 1 A, no guard ring | Higher VF increases conduction loss; larger footprint (4.5 × 2.7 mm); lacks stress protection for industrial transients | Preferable only when 1 A continuous current is required and PCB layout allows larger footprint. |
Compared with RB050M-30 and SS14, PMEG4005AEV uniquely combines 40 V rating, ultra-low VF, integrated guard ring, and ultra-compact SOT666 packaging - making it optimal for space- and efficiency-critical 3.3–12 V embedded power rails where reliability under electrical stress is mandatory.

FAQ
Can PMEG4005AEV be used in automotive applications?
No. PMEG4005AEV is not AEC-Q200 qualified and lacks automotive-grade screening, temperature cycling validation, or guaranteed operation above 125 °C ambient. Its 150 °C junction limit applies only to controlled industrial environments - automotive under-hood use requires explicitly qualified alternatives like PMEG3010AEJ.
How should the SOT666 package be soldered for optimal thermal performance?
Follow Nexperia's reflow profile for SOT666: peak temperature 260 °C, time above 217 °C ≤ 60 s. Use the recommended solder land pattern (Fig. 5) with full copper fill under the cathode tab (pins 1,2,5,6) and thermal vias to inner ground planes to achieve the specified 80 K/W Rth(j-sp).
What is the significance of the guard ring in PMEG4005AEV?
The integrated guard ring redistributes electric field lines at the die edge, suppressing premature avalanche breakdown during voltage transients or ESD events. This extends operational life in applications exposed to load dump, inductive kickback, or connector hot-plug surges - confirmed by IEC 61000-4-2 testing up to ±8 kV contact discharge.
Why does the datasheet specify different IFRM and IFSM values depending on pin connection?
IFRM = 3.5 A and IFSM = 10 A are only valid when pins 3 & 4 (anode) and pins 1,2,5 & 6 (cathode) are externally paralleled on the PCB. Without parallel routing, the device defaults to single-pin current ratings (IF = 0.5 A continuous), as thermal and current-sharing paths are not fully utilized.
