Product details
Overview
PMEG045V100EPDAZ from Nexperia is a 45 V, 10 A low forward-voltage MEGA Schottky barrier rectifier in a CFP15 (SOT1289) thermally enhanced SMD package, featuring integrated guard ring stress protection and clip-bonding for high power capability. It delivers VF = 420–490 mV at IF = 10 A and 25 °C, supports AEC-Q101 automotive qualification, and is used in DC-to-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG045V100EPDAZ datasheet, PMEG045V100EPDAZ pinout, PMEG045V100EPDAZ application, or PMEG045V100EPDAZ equivalent, key selection criteria include forward voltage at rated current, thermal resistance to solder point (Rth(j-sp) = 3 K/W), reverse leakage at 45 V (250–600 µA), AEC-Q101 qualification status, and CFP15 package footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky rectifier uses planar MEGA technology with an integrated guard ring to suppress edge breakdown and improve ruggedness under repetitive surge stress. Its clip-bonded construction directly connects the die to the cathode tab, minimizing thermal resistance and enabling high pulsed current handling (IFSM = 210 A).
The device exhibits ultra-low VF due to optimized metal-semiconductor interface and thin epitaxial layer design, while maintaining low trr (17–37 ns) and Cd (400–1190 pF) for high-frequency switching applications. Its thermal performance is defined across three mounting conditions: FR4 standard, FR4 with 1 cm² cathode pad, and Al₂O₃ ceramic PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 10 A | 420–490 mV at 25 °C - enables >95% efficiency in 5–12 V output DC/DC stages |
| VR | 45 V maximum - suitable for 36 V automotive rail and 24 V industrial bus systems |
| IF(AV) | 10 A average - supports continuous operation in compact 10–15 W power modules |
| Rth(j-sp) | 3 K/W - direct thermal path to solder point allows >2.15 W dissipation on ceramic PCB |
| trr | 17 ns (ramp), 37 ns (step) - minimizes switching losses in >500 kHz SMPS designs |
| IR @ 45 V | 250–600 µA at 25 °C - low leakage preserves battery life in always-on reverse protection |
| AEC-Q101 | Qualified - validated for automotive underhood temperature cycling and HTRB stress |
Pinout & Package
Encapsulated in a CFP15 (SOT1289) thermally enhanced ultra-thin SMD package (5.8 × 4.3 × 0.78 mm), with exposed cathode tab for direct PCB heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary anode connection; paralleled with Pin 2 for low-inductance, high-current input path |
| 2 | Anode | Secondary anode terminal; dual-anode layout reduces series resistance and improves current sharing |
| 3 | Cathode | Exposed metal tab - serves as main thermal and electrical return path; requires full-solder coverage for Rth(j-sp) = 3 K/W |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Prevents premature edge breakdown under high dv/dt and transient overvoltage, extending lifetime in noisy automotive environments |
| Clip-bonding technology | Eliminates wire bonds; reduces thermal resistance by >40% vs. conventional SOD packages and supports 210 A non-repetitive surge |
| Ultra-thin profile (0.78 mm) | Enables stacking in space-constrained modules (e.g., USB-C PD adapters, ECU power rails) without height interference |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling (−40 °C to +125 °C), HTRB, and ESD (HBM ≥ 2 kV) |
| Low VF temperature coefficient | VF drops to 330 mV at 125 °C - maintains high efficiency during thermal derating in enclosed enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-10SQ045ST | Same 45 V VR, 10 A IF(AV), but TO-277 package (higher Rth(j-a) = 45 K/W); VF = 480 mV typ at 10 A | Larger footprint and lower thermal performance; unsuitable for ultra-thin or high-power-density layouts | Select only when legacy TO-277 board reuse is required and thermal headroom exceeds 10 °C |
| ON Semiconductor NSR1045MW2T3G | CFP15-compatible, VF = 450 mV typ at 10 A, but not AEC-Q101 qualified; IR = 350 µA max at 45 V | Lacks automotive qualification and has higher leakage - limited to commercial-grade industrial use | Acceptable for cost-sensitive non-automotive 24 V systems where AEC compliance is not mandated |
Compared with VS-10SQ045ST and NSR1045MW2T3G, PMEG045V100EPDAZ uniquely combines AEC-Q101 qualification, lowest VF (420 mV), and best thermal resistance (Rth(j-sp) = 3 K/W), making it the preferred choice for space- and reliability-critical automotive and industrial power stages.

FAQ
What is the maximum junction temperature rating for PMEG045V100EPDAZ?
The absolute maximum junction temperature is 175 °C, verified per IEC 60134 limiting values. Operation up to this limit is permitted only under specified thermal conditions - e.g., with Rth(j-sp) ≤ 3 K/W on ceramic PCB and Tsp ≤ 155 °C. Derating curves in Figures 12 and 13 define safe IF(AV) limits across ambient and solder-point temperatures.
Does PMEG045V100EPDAZ support bidirectional current flow?
No - it is a unidirectional Schottky barrier rectifier. Current flows only from anode (Pins 1 and 2) to cathode (Pin 3). Reverse conduction is blocked up to 45 V, with leakage current limited to 600 µA at 45 V and 25 °C. It is not designed for synchronous rectification control or reverse-biased switching.
How does the dual-anode configuration affect PCB layout?
The dual-anode (Pins 1 and 2) must be routed as a single low-inductance node - typically connected via wide copper pour or parallel traces. Separating them introduces imbalance and localized heating. The cathode (Pin 3) requires ≥1 cm² soldered copper area for optimal thermal performance, per datasheet footnote [2] and Figure 10.
Is PMEG045V100EPDAZ compatible with lead-free reflow profiles?
Yes - it is qualified for standard lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C. The CFP15 package outline and solder footprint in Figure 18 specify land pattern dimensions, solder paste volume, and thermal relief design rules to prevent tombstoning and ensure void-free cathode tab soldering.
