Product details
Overview
PMEG4010CEH from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 40 V reverse voltage and 1 A forward current, featuring a typical forward voltage of 490 mV at 1 A and reverse leakage of only 6 µA at 40 V - deployed in low-voltage DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG4010CEH datasheet, PMEG4010CEH pinout, PMEG4010CEH application, or PMEG4010CEH equivalent, key selection criteria include ultra-low VF performance, SOD123F thermal resistance (Rth(j-sp) = 150 K/W), junction temperature limit of 150 °C, and cathode-marked SMD footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low forward voltage stems from optimized metal–semiconductor interface design, enabling efficient conduction at low voltages without significant thermal runaway risk.
Thermal performance is defined for two mounting conditions: standard FR4 footprint (Rth(j-a) = 330 K/W) and enhanced cathode pad (Rth(j-sp) = 150 K/W), supporting stable operation up to 150 °C junction temperature. Reverse recovery is inherently negligible due to majority-carrier conduction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 40 V - maximum blocking capability before avalanche onset; suitable for 24 V system rails with margin. |
| IF (Forward Current) | 1 A continuous - rated for sustained conduction at ambient ≤55 °C on standard FR4 PCB. |
| VF (Forward Voltage) | 490 mV typ. @ 1 A - reduces conduction loss by ~30% vs. standard silicon diodes, improving efficiency in 3.3–12 V DC-DC stages. |
| IR (Reverse Current) | 6 µA max @ 40 V, 25 °C - ensures minimal standby power loss in battery-backed or energy-sensitive applications. |
| Cd (Capacitance) | 69 pF typ. @ 1 V, 1 MHz - enables fast switching with low AC loss in high-frequency SMPS output rectification. |
| Rth(j-sp) | 150 K/W - thermal resistance to solder point with 1 cm² cathode pad; enables predictable derating in thermally constrained designs. |
Pinout & Package
Encapsulated in a compact SOD123F surface-mount plastic package (2.6 mm × 1.6 mm × 1.1 mm), with flat leads and cathode-bar marking for automated optical inspection and placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; marked by bar on package body; connects to output/ground side in rectifier or reverse protection configurations. |
| 2 | Anode (A) | Positive terminal; connects to input/power source side; carries full forward current during conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Very low VF Schottky architecture | 490 mV typ. @ 1 A - directly lowers I²R losses and improves power stage efficiency in space-constrained DC-DC modules. |
| Integrated guard ring | Suppresses edge-related breakdown - enhances robustness against voltage transients and layout-induced field concentration. |
| SOD123F package | 2.6 mm × 1.6 mm footprint with flat leads - supports high-density routing and reflow-compatible assembly without tombstoning risk. |
| Low reverse leakage | 6 µA max @ 40 V - minimizes quiescent current drain in always-on systems such as IoT sensors and backup power paths. |
Applications
| Low-Voltage Rectification | High-Efficiency DC-DC Conversion |
|---|---|
Use Scenario: Converting 5 V or 3.3 V USB-supplied power to regulated logic rails in portable electronics. IC Role / Device Role / Timing Role: Output rectifier in synchronous or asynchronous buck converter secondary stage. Use Value: 490 mV VF reduces conduction loss by >200 mW vs. standard Schottky alternatives, extending battery runtime. |
Use Scenario: Secondary-side rectification in isolated flyback or forward converters for industrial control modules. IC Role / Device Role / Timing Role: Unidirectional current path enabling efficient energy transfer during switch off-time. Use Value: 69 pF capacitance and negligible reverse recovery minimize switching node ringing and EMI generation. |
| Reverse Polarity Protection | Low-Power Consumption Systems |
Use Scenario: Preventing damage from incorrect battery insertion in handheld medical devices and wearables. IC Role / Device Role / Timing Role: Series-connected cathode-to-load protection diode in input power path. Use Value: Low 490 mV drop preserves >95% of 3.7 V Li-ion voltage under 1 A load, avoiding brownout in critical subsystems. |
Use Scenario: Always-on power monitoring circuitry in smart meters and environmental sensors. IC Role / Device Role / Timing Role: Isolation element in auxiliary supply rail to prevent backfeed during main power failure. Use Value: 6 µA IR at 40 V limits standby current to sub-microamp level, enabling >10-year battery life in coin-cell designs. |
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 NSS40100U1T6G | Same 40 V/1 A rating but VF = 550 mV typ. @ 1 A; higher IR = 10 µA @ 40 V. | Marginally lower efficiency in high-duty-cycle DC-DC; acceptable where thermal headroom exists. | Select when sourcing diversity is required and 60 mV VF penalty is tolerable for cost or lead-time reasons. |
| Vishay SS14HM3/84A | 40 V/1 A, VF = 500 mV typ., but SOD-123 package (not SOD123F); slightly larger footprint and higher Rth(j-a). | Compatible functionally but requires PCB land pattern revision; less optimal for ultra-thin or high-density assemblies. | Choose only if legacy SOD-123 footprint compatibility is mandatory and thermal derating is verified. |
Compared with NSS40100U1T6G and SS14HM3/84A, PMEG4010CEH delivers the lowest VF (490 mV) and tightest IR (6 µA), with SOD123F's optimized thermal path (Rth(j-sp) = 150 K/W) making it preferred for thermally aggressive, space-constrained 1 A rectification tasks.

FAQ
What is the maximum junction temperature for PMEG4010CEH?
The absolute maximum junction temperature is 150 °C, validated per IEC 60134 limiting values. Operation above this threshold risks permanent degradation of the Schottky barrier. Derating curves in the datasheet define safe IF vs. Tamb limits, especially critical when using the standard FR4 footprint (Rth(j-a) = 330 K/W).
Is PMEG4010CEH suitable for automotive applications?
No - this part is explicitly non-automotive qualified, as confirmed in the 2023 revision history. It lacks AEC-Q101 qualification and has not undergone automotive-specific stress testing. For automotive use, Nexperia offers the PMEG4010CEJ-Q variant, which is AEC-Q101 qualified and documented separately.
How does the SOD123F package differ from standard SOD-123?
SOD123F features flatter, more coplanar leads than SOD-123, reducing tombstoning risk during reflow and improving solder joint reliability. Its body height is 1.1 mm (vs. ~1.3 mm for SOD-123), enabling thinner end products. The thermal pad configuration also differs, supporting lower Rth(j-sp) = 150 K/W with a dedicated 1 cm² cathode pad.
What is the significance of the guard ring in PMEG4010CEH?
The integrated guard ring mitigates electric field crowding at the die edge, preventing premature avalanche breakdown under high dv/dt or mechanical stress. This improves surge robustness - particularly important in DC-DC converters exposed to input transients - and extends operational lifetime compared to guard-ring-free Schottky diodes.
