Product details
Overview
PMEG045V100EIPE from Nexperia is a 45 V, 10 A planar low forward voltage Schottky barrier rectifier in a CFP15B (SOT1289B) thermally enhanced ultra-thin SMD package, designed for high-efficiency DC-to-DC conversion and freewheeling applications where low conduction loss and fast switching are critical. It delivers VF = 490–540 mV at 10 A/25 °C, IR ≤ 500 µA at 45 V, and supports IFSM = 210 A non-repetitive peak current.
For engineers reviewing the PMEG045V100EIPE datasheet, PMEG045V100EIPE pinout, PMEG045V100EIPE application, or PMEG045V100EIPE equivalent, key selection criteria include forward voltage at rated current, thermal resistance to solder point (Rth(j-sp) = 3 K/W), reverse leakage under full VR, and compatibility with high-frequency SMPS layouts requiring minimal footprint and low profile.
Technical Context
This Schottky rectifier uses clip-bond technology to achieve low VF and high power capability in a 5.8 × 4.3 × 0.95 mm flat-lead package. Its planar junction structure enables stable reverse recovery (trr ≤ 22 ns step, ≤ 15 ns ramp) and negligible minority-carrier storage, eliminating tail current during turn-off.
The device operates with Tj up to 175 °C and features dual anode terminals (Pins 1 & 2) and a cathode tab (Pin 3), enabling low-inductance PCB layout and direct thermal coupling to copper pour. Rth(j-a) = 90 K/W (standard FR4) and Rth(j-sp) = 3 K/W confirm its suitability for high-current, space-constrained power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 45 V maximum reverse voltage - defines safe blocking capability in OR-ing and reverse polarity protection circuits |
| IF(AV) | 10 A average forward current - sustained DC or square-wave (δ = 0.5, f = 20 kHz) rating under Tsp ≤ 170 °C |
| VF @ 10 A | 490–540 mV at 25 °C - enables <1.5 W conduction loss at full load, critical for >95% efficiency in 12 V/48 V DC-DC stages |
| IR @ 45 V | 100–500 µA at 25 °C - low leakage preserves battery runtime in always-on reverse-polarity protection |
| trr | ≤22 ns (step), ≤15 ns (ramp) - ensures clean commutation in synchronous rectifiers and high-frequency flyback snubbers |
| Rth(j-sp) | 3 K/W - allows direct thermal path from junction to solder point, supporting >2 W dissipation on 1 cm² cathode pad |
| IFSМ | 210 A peak (8.3 ms half-sine) - withstands inrush and transient overloads in industrial power supplies |
Pinout & Package

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-10BQ040-M3/45 | 40 V VR, 10 A IF(AV), VF = 480 mV @ 10 A, TO-277 package (3.05 mm height) | Lower VR rating limits use in 45 V systems; taller profile restricts ultra-thin designs | Select only if VR margin <5 V is acceptable and board height >3 mm is available |
| ON Semiconductor MBR1045CT | 45 V VR, 10 A IF(AV), VF = 620 mV @ 10 A, TO-220AB package (9.1 mm height) | Higher VF increases conduction loss by ~1.3 W; through-hole mounting incompatible with full SMT lines | Use only for prototyping or legacy through-hole designs where thermal mass outweighs efficiency penalty |
Compared with VS-10BQ040-M3/45 and MBR1045CT, PMEG045V100EIPE offers superior VR margin, lowest VF among SMD 45 V/10 A Schottkys, and the thinnest profile-enabling higher power density in modern DC-DC modules where thermal and spatial constraints dominate.

FAQ
What is the maximum junction temperature and how does it affect derating?
The PMEG045V100EIPE has a maximum junction temperature (Tj) of 175 °C. Derating follows ambient and solder point temperature curves in Figures 8–10 of the datasheet: at Tamb = 70 °C with standard FR4 footprint, IF(AV) drops to ~7.5 A; with 1 cm² cathode pad, it sustains ~9.2 A. Exceeding Tj = 175 °C risks permanent parametric shift or metallization failure.
Can this Schottky be used in place of a silicon PN diode in a 48 V input SMPS?
Yes-its 45 V VR rating provides adequate margin for 48 V nominal inputs with typical transients (e.g., ISO 7637-2 Pulse 1/2). With VF ≈ 500 mV vs. ~1.1 V for silicon, it reduces conduction loss by >50%, lowering thermal stress and improving light-load efficiency. Ensure layout minimizes parasitic inductance due to fast trr.
How does the dual-anode (Pins 1 & 2) configuration improve performance?
The dual-anode structure halves effective series resistance and inductance per path, distributing current evenly and reducing localized heating. In PCB layout, connecting both pins to the same high-current net lowers total loop inductance-critical for minimizing voltage spikes during fast switching in synchronous rectifier topologies.
Is the CFP15B package compatible with standard reflow profiles?
Yes-the CFP15B (SOT1289B) is qualified for lead-free reflow per J-STD-020. Recommended stencil thickness is 0.125 mm; cathode pad requires 1 cm² copper area for optimal thermal performance. Peak temperature must not exceed 260 °C for ≤30 seconds, with ramp rates within JEDEC Class 3 limits.
