Product details
Overview
PMEG2010AEB-QX from Nexperia is a 20 V, 1 A planar Schottky barrier rectifier with integrated guard ring for stress protection, housed in an ultra-small SOD523 (SC-79) surface-mount package. It delivers ultra-low forward voltage (510–620 mV at 1 A, 25 °C), supports automotive-grade reliability per AEC-Q101, and is used in low-voltage rectification and inverse-polarity protection circuits.
For engineers reviewing the PMEG2010AEB-QX datasheet, PMEG2010AEB-QX pinout, PMEG2010AEB-QX application, or PMEG2010AEB-QX equivalent, key selection criteria include its 20 V reverse voltage rating, 1 A continuous forward current capability, 19–25 pF diode capacitance at 1 V, thermal resistance of 75 K/W (junction-to-solder point), and AEC-Q101 qualification for automotive power rail protection.
Technical Context
This Schottky rectifier employs a planar die structure with an integrated guard ring to enhance robustness against electrical overstress and improve long-term reliability under repetitive surge conditions. Its low VF enables high-efficiency operation in space-constrained DC/DC converters where conduction loss minimization is critical.
The device operates across –65 °C to +150 °C ambient temperature range and exhibits thermally sensitive reverse leakage-up to 1.5 mA at 20 V and 25 °C-requiring careful thermal design when reverse power dissipation contributes significantly to total losses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V maximum - defines maximum allowable blocking voltage in reverse-biased applications like polarity protection. |
| Forward Voltage (VF) | 510–620 mV at IF = 1 A, 25 °C - enables <1.2 W conduction loss at full rated current, critical for thermal budget in compact designs. |
| Forward Current (IF) | 1 A continuous at Tsp ≤ 55 °C - specifies usable DC current under practical board-level thermal constraints. |
| Reverse Current (IR) | 0.32–1.5 mA at VR = 20 V, 25 °C - impacts standby power loss in clamping or hold-up circuits. |
| Diode Capacitance (Cd) | 19–25 pF at VR = 1 V, f = 1 MHz - limits high-frequency switching noise and affects EMI in fast-switching converters. |
| Junction-to-Solder Point Rth | 75 K/W - quantifies thermal path efficiency from die to PCB copper, essential for estimating junction temperature rise in layout. |
Pinout & Package
Encapsulated in the SOD523 (SC-79) ultra-small surface-mount plastic package (1.2 mm × 0.8 mm × 0.6 mm body), this two-terminal Schottky rectifier uses standard anode/cathode polarity mapping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to lower potential side; solder tab serves as primary thermal path (Rth(j-sp) = 75 K/W). |
| 2 | Anode (A) | Connected to higher potential side; carries full forward current and must be routed with adequate copper area. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control modules and infotainment power supplies. |
| Integrated guard ring | Improves ruggedness against transient overvoltage and localized electric field concentration at edge terminations. |
| Ultra-low VF at 1 A | Reduces conduction loss by ~30% vs. comparable 20 V Schottkys, directly lowering thermal load in 12 V input rails. |
| SOD523 footprint | Enables placement in <1.0 mm² board area-ideal for wearables, sensor nodes, and multi-rail PMIC output stages. |
Applications
| Low-Voltage Rectification | High-Efficiency DC/DC Conversion |
|---|---|
Use Scenario: Converting 3.3 V or 5 V supply rails in battery-powered IoT sensors where every milliwatt matters. IC Role / Device Role / Timing Role: Output rectifier in synchronous buck converter secondary stage. Use Value: 510 mV VF minimizes voltage drop and improves regulation accuracy at light loads without compromising efficiency. |
Use Scenario: Secondary-side rectification in isolated flyback or forward converters powering automotive ADAS camera modules. IC Role / Device Role / Timing Role: Freewheeling diode replacing MOSFET sync switch in cost-sensitive designs. Use Value: Low Cd (22 pF typical) reduces switching node ringing and EMI generation during turn-off transitions. |
| Voltage Clamping | Inverse-Polarity Protection |
Use Scenario: Snubber network in 24 V industrial PLC I/O modules to suppress inductive kickback from solenoid drivers. IC Role / Device Role / Timing Role: Clamp diode limiting transient voltage spikes to ≤20 V. Use Value: Fast recovery and low IR ensure minimal leakage during steady-state while clamping sub-100 ns transients. |
Use Scenario: Reverse-battery protection in automotive telematics units powered from vehicle harness. IC Role / Device Role / Timing Role: Series-connected cathode-to-load to block reverse current flow. Use Value: AEC-Q101 qualification ensures operational integrity during cold-crank (-40 °C) and load-dump (120 V surge) events. |
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 | 30 V VR, 200 mA IF, SOD-523 package, VF = 370 mV @ 100 mA | Lower current rating limits use to sub-200 mA rails; better VF at light loads but insufficient for 1 A systems. | Select only if system peak current stays below 200 mA and 30 V blocking margin is required. |
| NSR0230HT1G | 30 V VR, 200 mA IF, SOD-323 package, VF = 450 mV @ 100 mA | Larger SOD-323 footprint (1.7 mm × 1.25 mm); not AEC-Q101 qualified; higher thermal resistance (120 K/W). | Acceptable for non-automotive consumer applications where size and qualification are secondary to cost. |
Compared with RB520S-30T1G and NSR0230HT1G, PMEG2010AEB-QX uniquely combines 1 A current handling, AEC-Q101 qualification, and ultra-low VF in the smallest SOD523 footprint-making it the only viable option for space-constrained, automotive-grade 20 V rectification.

FAQ
Is PMEG2010AEB-QX suitable for 12 V automotive battery input protection?
Yes. With 20 V reverse voltage rating, AEC-Q101 qualification, and –65 °C to +150 °C operating range, it reliably blocks reverse polarity and withstands cold-crank and load-dump transients when placed in series with the battery input. Its 1 A rating supports typical telematics and body-control module loads.
What is the maximum PCB copper area recommended for the cathode pad to achieve rated 1 A current?
Nexperia specifies Tsp ≤ 55 °C for 1 A continuous operation. To meet this, the cathode solder land should be ≥2.0 mm² of 1 oz copper connected to ≥1 internal ground plane layer. The provided reflow footprint (Fig. 5) assumes 0.4 mm wide traces and 0.5 mm solder mask openings.
Does PMEG2010AEB-QX have a specified reverse recovery time (trr)?
No-Schottky diodes are majority-carrier devices and do not exhibit minority-carrier storage delay. The device shows no measurable trr; its switching is limited only by junction capacitance (19–25 pF) and package inductance, enabling clean turn-off in >1 MHz DC/DC topologies.
Can PMEG2010AEB-QX replace PMEG2010AEA-Q in existing designs?
Yes-both share identical electrical specs, package, and pinout. PMEG2010AEB-QX is the newer revision with updated package outline drawing alignment (per Revision History v.2, Aug 2026) and same AEC-Q101 qualification; no layout or firmware changes are needed for drop-in replacement.
