Product details
Overview
PMEG3005EEFZ from Nexperia is a 30 V, 0.5 A planar MEGA Schottky barrier rectifier in an ultra-small DFN0603-2 (SOD972E) leadless SMD package, featuring low forward voltage (560–670 mV at 500 mA), low leakage current (2.1–15 µA at 30 V), and integrated guard ring for stress protection - deployed in mobile LED backlighting and high-efficiency DC-DC converters.
For engineers reviewing the PMEG3005EEFZ datasheet, PMEG3005EEFZ pinout, PMEG3005EEFZ application, or PMEG3005EEFZ equivalent, this diode is selected for ultra-thin portable power rails where <0.25 mm profile, sub-1 V forward drop, and fast reverse recovery (<2 ns) directly impact battery runtime and thermal margin in space-constrained designs.
Technical Context
This Schottky rectifier uses a planar MEGA structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient voltage stress. Its low junction capacitance (7–17 pF) and negligible reverse recovery time enable operation in high-frequency switching topologies up to several MHz.
The device operates with a maximum junction temperature of 150 °C and achieves thermal resistance of 35 K/W from junction to solder point when mounted on 1 cm² copper pads - critical for maintaining stable VF and IR performance in thermally dense PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - supports input rails up to 24 V nominal with 25 % safety margin against transients |
| Average Forward Current (IF(AV)) | 0.5 A - delivers continuous output in compact DC-DC buck stages powering baseband ICs or display drivers |
| Forward Voltage (VF) | 560–670 mV @ 500 mA - reduces conduction loss by >40 % vs. standard silicon diodes, improving efficiency in 1–3 W power blocks |
| Reverse Current (IR) | 2.1–15 µA @ 30 V - minimizes standby power drain in always-on mobile subsystems like touch controllers or RTC circuits |
| Reverse Recovery Time (trr) | <2 ns - eliminates switching tail current, enabling clean zero-voltage switching in synchronous rectifier-assisted topologies |
| Package Dimensions | 0.63 × 0.33 × 0.25 mm - fits within 0.75 mm × 0.85 mm reflow footprint, compatible with 0201-class placement equipment |
| Junction-to-Solder-Point Rth | 35 K/W - enables 570 mW power dissipation with ≤25 °C rise above solder point, supporting high-density thermal layout |
Pinout & Package
DFN0603-2 (SOD972E) is a 2-terminal, ultra-thin (0.25 mm typ.), leadless surface-mount package with exposed cathode and anode terminals on the bottom side. The cathode is marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to output rail or ground return path; requires full-copper thermal pad for heat extraction |
| 2 (A) | Anode | Connected to switch node or input rail; polarity-sensitive - reverse connection causes immediate conduction failure |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Prevents premature edge breakdown under repetitive surge conditions, extending lifetime in unregulated input stages |
| Ultra-low profile (0.25 mm) | Enables stacking under thin-film shields or beneath flex connectors in foldable/mobile form factors |
| Low leakage (2.1 µA typ.) | Reduces quiescent current in battery-backed circuits - critical for >1-year shelf life in IoT sensors |
| High-speed switching (trr <2 ns) | Eliminates need for snubbers in 1–3 MHz boost converters, simplifying BOM and layout |
| Thermal pad-compatible footprint | Supports direct thermal coupling to internal ground planes via solder mask defined pads, lowering junction temp by ≥15 °C |
Applications
| Mobile LED Backlighting | USB-C Power Delivery Snubber |
|---|---|
Use Scenario: Driving white LEDs in smartphone displays using a 5 V boost converter with PWM dimming. IC Role / Device Role / Timing Role: Output rectifier in asynchronous boost stage, conducting during low-side switch off-time. Use Value: Low VF minimizes voltage headroom loss, enabling full LED brightness at 4.2 V battery; 0.25 mm height avoids interference with touch sensor stack-up. |
Use Scenario: Clamp diode across USB-C CC line ESD protection array to prevent latch-up during hot-plug events. IC Role / Device Role / Timing Role: Fast clamping diode shunting transient energy to ground before TVS triggers. Use Value: Sub-2 ns trr ensures clamping response precedes 10/1000 µs surge waveform peak; low IR avoids DC loading on CC bias network. |
| Wearable Battery Charger IC Output | Low-Power BLE SoC Power Rail |
Use Scenario: Rectifying output of a 1.2 MHz buck-boost charger IC supplying 3.3 V to a Li-ion cell management circuit. IC Role / Device Role / Timing Role: Synchronous rectifier replacement in discontinuous conduction mode (DCM) operation. Use Value: 560 mV VF reduces average conduction loss by 120 mW vs. Si diode, extending charge cycle duration in coin-cell-powered wearables. |
Use Scenario: Reverse-polarity protection on 1.8 V supply rail feeding Bluetooth Low Energy radio and sensor fusion MCU. IC Role / Device Role / Timing Role: Series blocking diode preventing damage from accidental battery reversal during field servicing. Use Value: 2.1 µA IR ensures <1 µA total rail leakage, preserving >98 % of 10 µA sleep current budget; DFN0603-2 fits within 1.2 mm² board area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-30T2R | Higher VF (750 mV typ. @ 500 mA); same 30 V VR; SOD-523 package (0.9 × 0.7 × 0.5 mm) | Less suitable for ultra-thin mobile backlight due to 2× height and +190 mV VF penalty | Select only if legacy SOD-523 footprint compatibility is required over size/efficiency optimization |
| NSR0530HT1G | Same VF range (550–650 mV); higher IF(AV) = 0.6 A; SOD-123FL package (1.7 × 0.9 × 0.7 mm) | Too large for space-constrained wearable PCBs; better suited for industrial DC-DC modules | Choose when higher current headroom and thermal mass outweigh strict height constraints |
Compared with RB521S-30T2R and NSR0530HT1G, PMEG3005EEFZ provides the smallest footprint (0.21 mm²), lowest profile (0.25 mm), and best VF/size trade-off for mobile and wearable power rails - making it optimal where board thickness and conversion efficiency are co-constrained.

FAQ
Is PMEG3005EEFZ suitable for automotive applications?
No. PMEG3005EEFZ is not AEC-Q200 qualified and lacks automotive-grade screening, temperature cycling validation, or guaranteed operation beyond 125 °C ambient. It is specified for commercial and industrial portable electronics only - use Nexperia's PMEG3010AEB or PMEG6020AEB for automotive infotainment or ADAS power rails.
What is the recommended reflow profile for DFN0603-2 packaging?
The DFN0603-2 package requires a peak reflow temperature of 260 °C for ≤10 seconds, with ramp-up rate ≤3 °C/s and cooling rate ≤6 °C/s. Use the footprint in Figure 14 (0.28 × 0.75 mm lands, 0.19 mm solder paste stencil) to ensure void-free solder joints and mechanical reliability under thermal cycling.
Does PMEG3005EEFZ have polarity marking on the top surface?
Yes. A single bar marking on the top surface indicates the cathode terminal (Pin 1). This aligns with the simplified outline in Table 2 and the "Indication of Cathode" note in Figure 13 - essential for automated optical inspection (AOI) and manual verification during prototype assembly.
How does the guard ring affect surge robustness?
The integrated guard ring redistributes electric field intensity at the die periphery, raising the effective reverse breakdown voltage under transient conditions. Tested per IEC 61000-4-5, PMEG3005EEFZ withstands 1 A 8/20 µs surges without parameter shift - unlike non-guarded Schottkys that degrade after repeated 0.5 A events.
