Product details
Overview
PMEG4002EL-QYL from Nexperia is a 40 V, 0.2 A planar MEGA Schottky barrier rectifier in a leadless DFN1006-2 (SOD882) package, featuring low forward voltage (520–600 mV at 200 mA), AEC-Q101 qualification, and integrated guard ring for stress protection-used in automotive voltage clamping and low-power rectification circuits.
For engineers reviewing the PMEG4002EL-QYL datasheet, PMEG4002EL-QYL pinout, PMEG4002EL-QYL application, or PMEG4002EL-QYL equivalent, key selection criteria include forward voltage at 200 mA, reverse leakage at 40 V, thermal resistance (500 K/W), junction temperature rating (150 °C), and SOD882 footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky diode employs a planar MEGA structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress-critical for automotive load-dump and ESD-prone environments. Its ultra-low VF enables efficient operation in 3.3 V and 5 V rail protection and blocking applications.
Designed for surface-mount reflow assembly on FR4 PCBs with standard SOD882 footprints, it delivers power dissipation comparable to SOT23 while occupying only 0.6 mm² area. Thermal runaway risk is mitigated via controlled reverse current (<10 µA at 40 V, 25 °C) and specified junction-to-ambient thermal resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - supports 24 V automotive systems with margin against load-dump transients |
| Forward Current (IF) | 0.2 A continuous - suitable for low-power signal path and bias rail rectification |
| Forward Voltage (VF) | 520–600 mV at 200 mA - reduces conduction loss in battery-powered and energy-sensitive designs |
| Reverse Leakage (IR) | 0.7–10 µA at 40 V - ensures minimal standby current in always-on automotive modules |
| Diode Capacitance (Cd) | 14–20 pF at 1 V - enables use in <100 MHz clamping and high-speed switching circuits |
| Junction Temperature (Tj) | 150 °C max - qualified for under-hood automotive environments per AEC-Q101 |
| Thermal Resistance (Rth(j-a)) | 500 K/W - requires careful PCB copper area design to maintain safe operating temperature |
Pinout & Package
Encapsulated in a leadless DFN1006-2 (SOD882) plastic package measuring 1.0 mm × 0.6 mm × 0.48 mm with 0.65 mm pitch; cathode indicated by marking bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output/return node for forward conduction; marked side of package |
| 2 | Anode (A) | Input/anode terminal; connects to higher-potential source during conduction |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Prevents edge breakdown under high dv/dt and mechanical stress-enhances robustness in automotive transients |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTGB, HTRB, and temperature cycling per discrete semiconductor standard |
| Ultra-small footprint | 0.6 mm² board area-enables placement in space-constrained modules like camera ECUs and ADAS sensors |
| Low thermal resistance packaging | 500 K/W junction-to-ambient-supports thermal management without heatsinks in low-power applications |
| Pulsed forward current rating | 3 A non-repetitive peak (8 ms)-handles short-duration surge events such as ESD or inductive kickback |
Applications
| Automotive Camera Power Protection | USB Port Polarity Protection |
|---|---|
Use Scenario: Protecting 5 V power input of rear-view camera modules from reverse polarity connection during service. IC Role / Device Role / Timing Role: Blocking diode preventing damage to downstream LDOs and image sensors when external power is miswired. Use Value: Low VF minimizes voltage drop across protection path, preserving headroom for 4.75 V minimum camera supply requirement. |
Use Scenario: Preventing backfeed between dual USB power sources in portable diagnostic tools. IC Role / Device Role / Timing Role: Unidirectional current gate ensuring isolated power domains remain electrically separated. Use Value: 14–20 pF capacitance avoids signal integrity degradation on USB 2.0 data lines (480 Mbps). |

Use Scenario: Rectifying trickle-charge current from energy-harvesting piezoelectric sources powering wireless sensor nodes. IC Role / Device Role / Timing Role: Low-leakage rectifier capturing microamp-level AC pulses into DC storage capacitors. Use Value: Sub-1 µA IR at low VR enables >99% charge retention over multi-day idle periods. |
Use Scenario: Clamping 24 V digital input transients induced by relay coil flyback in factory automation controllers. IC Role / Device Role / Timing Role: Fast-turn-on Schottky clamp diverting >1 kV/µs spikes away from MCU GPIO pins.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-40T1G | Higher VF (600–700 mV at 200 mA); same 40 V VR; SOD-523 package (smaller, 1.2 mm²) | Less suitable for ultra-low-drop applications but offers better thermal performance due to larger pad exposure | Select when PCB layout permits SOD-523 and slightly higher VF is acceptable for improved manufacturability |
| NSR0240HT1G | Lower IF rating (0.12 A); identical VF range; same SOD-882 footprint and AEC-Q101 qualification | Not recommended for 200 mA continuous loads but sufficient for 100 mA signal-path clamping | Choose only for cost-sensitive, sub-100 mA applications where full 0.2 A capability is unnecessary |
Compared with RB520S-40T1G and NSR0240HT1G, PMEG4002EL-QYL uniquely balances 0.2 A current handling, lowest VF in its class, and AEC-Q101 compliance within the smallest standardized SOD882 footprint-making it optimal for space- and efficiency-critical automotive modules.

FAQ
What is the maximum allowable ambient temperature for continuous operation?
The PMEG4002EL-QYL is rated for ambient temperatures from −65 °C to +150 °C, but continuous operation at the upper limit requires strict adherence to thermal design guidelines-including minimum copper area per JEDEC Std. 51-3 and zero airflow assumptions. At 150 °C Tamb, derating to ≤0.1 A IF is recommended to maintain Tj ≤ 150 °C.
Does the cathode marking apply to both top-side silkscreen and physical package feature?
Yes-the cathode is unambiguously identified by a visible marking bar on the top surface of the DFN1006-2 package, aligned with Pin 1 per Table 2. No silkscreen is required on the PCB since the package itself provides orientation reference; this eliminates assembly ambiguity in automated placement.
Can this diode be used in reverse-biased Zener-like clamp configurations?
No-PMEG4002EL-QYL is a Schottky barrier rectifier, not a Zener diode. Its reverse breakdown voltage is not characterized or guaranteed; operation above 40 V VR risks irreversible damage. For clamping, it must be forward-biased (anode positive relative to cathode) or used in series-back configuration with another diode.
Is the 500 K/W Rth(j-a) value measured on a specific PCB layout?
Yes-this value is defined per IEC 60134 using standard SOD882 mounting conditions: FR4 board with 60 µm copper traces, no thermal vias, and free-air convection. Achieving lower thermal resistance requires adding thermal pads, solder-mask-defined copper, or thermal vias-designers should consult Nexperia's AN11120 for validated layout examples.
