Product details
Overview
PMEG4010BEA-QX from Nexperia is a 1 A, 40 V automotive-qualified MEGA Schottky barrier rectifier in SOD323 package, featuring ultra-low forward voltage (540–640 mV at 1 A, 25 °C), integrated guard ring for stress protection, and optimized for low-power DC-to-DC conversion and reverse-polarity protection in space-constrained automotive ECUs.
For engineers reviewing the PMEG4010BEA-QX datasheet, PMEG4010BEA-QX pinout, PMEG4010BEA-QX application, or PMEG4010BEA-QX equivalent, key selection criteria include VF vs. IF performance at 85–150 °C, AEC-Q101 qualification status, thermal resistance to solder point (90 K/W), and cathode-anode polarity alignment in high-density PCB layouts.
Technical Context
This Schottky diode employs planar MEGA technology with an integrated guard ring to suppress edge breakdown under transient stress-critical for automotive load-dump and ISO 7637-2 pulse immunity. Its low-junction-capacitance (43–50 pF at 1 V) and fast recovery enable efficient high-frequency rectification without snubbers.
The device operates within a junction temperature range of –65 °C to 150 °C and delivers 10 A non-repetitive peak forward current (8 ms square wave), supporting robust surge handling in battery-input protection circuits where thermal runaway must be mitigated via layout-aware Rth(j-sp) management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 540–640 mV @ 1 A, 25 °C - enables <100 mW conduction loss in 3.3 V/5 V rail clamping |
| Reverse Voltage (VR) | 40 V - supports 24 V automotive systems with 100 % margin over nominal 13.5–16 V battery rails |
| Forward Current (IF) | 1 A continuous @ Tsp ≤ 55 °C - defines max steady-state power delivery in FR4 PCB layouts with standard footprint |
| Reverse Current (IR) | 30–100 µA @ 40 V, 25 °C - ensures minimal leakage in always-on vehicle modules (e.g., CAN wake-up circuits) |
| Diode Capacitance (Cd) | 43–50 pF @ 1 V, 1 MHz - preserves signal integrity in high-speed switching nodes (e.g., buck converter sync rectification) |
| Thermal Resistance (Rth(j-sp)) | 90 K/W - enables direct thermal coupling to cathode pad for localized heat extraction in compact ECU designs |
| AEC-Q101 Qualified | Yes - validated for automotive discrete semiconductor stress testing including HTRB, HTGB, and temperature cycling |
Pinout & Package
Encapsulated in SOD323 (SC-76) surface-mount plastic package: 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, cathode marked with bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to system ground or lower-potential node; primary heat path to PCB copper pour |
| 2 | Anode (A) | Connected to input source (e.g., battery +); polarity-sensitive placement prevents reverse conduction |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF Schottky architecture | Reduces forward conduction loss by ≥30 % vs. standard Schottkys at 500 mA, extending battery runtime in portable automotive sensors |
| Integrated guard ring | Suppresses electric field crowding at die edges, enabling stable 40 V blocking without derating in humid or contaminated environments |
| SOD323 footprint | Minimizes PCB area (2.125 mm²) while maintaining manufacturability on standard reflow lines-no special tooling required |
| AEC-Q101 qualification | Validates reliability for 15-year automotive service life under thermal cycling (–40 °C to +125 °C) and humidity exposure |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Protection |
|---|---|
Use Scenario: Reverse-polarity protection on 12 V supply input to BCM microcontroller domain. IC Role / Device Role / Timing Role: Unidirectional blocking diode preventing damage during jump-start misconnection. Use Value: 40 V VR rating accommodates load-dump transients up to 35 V; 1 A IF sustains MCU + CAN transceiver + LED driver loads. |

Use Value: 10 A IFSM handles 200 ms inductive spikes; 43 pF Cd avoids signal distortion on 10 kHz input sampling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0140HT1G | Same 40 V VR, but VF = 450–550 mV @ 1 A - 90 mV lower typical VF; no AEC-Q101 documentation provided | Not qualified for automotive use; suitable for industrial/commercial DC-DC where qualification is not mandated | Select when lowest possible VF is prioritized and automotive qualification is unnecessary |
| Vishay SS14HM3/84A | Higher IF = 1.4 A, but VF = 550–750 mV @ 1 A; AEC-Q101 qualified; SMC (DO-214AC) package - 3× larger footprint | Acceptable for board space–tolerant designs requiring higher surge current margin | Select when 10 A IFSM headroom is critical and PCB area is not constrained |
Compared with NSR0140HT1G and SS14HM3/84A, PMEG4010BEA-QX uniquely balances AEC-Q101 compliance, ultra-compact SOD323 size, and sub-640 mV VF-making it optimal for next-gen automotive modules where space, qualification, and efficiency are jointly constrained.

FAQ
Is PMEG4010BEA-QX pin-compatible with standard SOD323 Schottky diodes?
Yes-PMEG4010BEA-QX uses the industry-standard SOD323 (SC-76) package with cathode (Pin 1) and anode (Pin 2) pinning per JEDEC MO-203. Its footprint matches generic SOD323 land patterns, including those defined in Nexperia's Fig. 5 (reflow) and Fig. 6 (wave) soldering guidelines.
What is the maximum allowable PCB copper area for optimal thermal performance?
For Rth(j-sp) = 90 K/W, Nexperia specifies a 1 cm² mounting pad for the cathode tab on single-sided FR4 PCBs. Using less than 1 cm² increases thermal resistance nonlinearly-e.g., 0.25 cm² raises Rth(j-sp) to ~180 K/W per thermal characterization data.
Does PMEG4010BEA-QX require derating at elevated ambient temperatures?
Yes-continuous forward current must be reduced above Tsp = 55 °C per the datasheet's derating curve. At 85 °C ambient, IF is limited to ~0.65 A on standard FR4; at 125 °C, it drops to ~0.25 A to maintain Tj ≤ 150 °C.
Can PMEG4010BEA-QX replace PN-junction diodes in existing 5 V rail designs?
Yes-its 40 V VR and 1 A IF exceed typical 5 V rail requirements, and its 540–640 mV VF reduces conduction loss by ~65 % versus a 1N4001 (1.1 V). However, verify reverse leakage (30–100 µA) is acceptable in ultra-low-power sleep modes before substitution.
