Product details
Overview
PMEG045V050EPDAZ from Nexperia is a 45 V, 5 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 425–490 mV forward voltage at 5 A and 25 °C, enabling high-efficiency DC-to-DC conversion and freewheeling in automotive and industrial power supplies.
For engineers reviewing the PMEG045V050EPDAZ datasheet, PMEG045V050EPDAZ pinout, PMEG045V050EPDAZ application, or PMEG045V050EPDAZ equivalent, key selection criteria include its AEC-Q101 qualification, ultra-low VF, 0.78 mm profile, thermal resistance to solder point of 3 K/W, and dual-anode/cathode terminal configuration for high-current PCB routing.
Technical Context
This Schottky rectifier uses planar MEGA technology with an integrated guard ring to suppress edge breakdown and improve reliability under repetitive surge stress. Its clip-bonded construction directly connects the die to the cathode thermal pad, reducing Rth(j-sp) to 3 K/W and supporting 160 A non-repetitive peak forward current.
The device exhibits negligible reverse recovery (trr ≤ 19 ns step, ≤12 ns ramp) and low capacitance (190 pF at 10 V), making it suitable for high-frequency switching topologies up to several MHz. Its VF remains stable across temperature - 340 mV typical at 5 A and 125 °C - ensuring consistent conduction loss in thermally demanding environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 45 V - Maximum blocking capability without avalanche breakdown; supports 36 V nominal bus systems with 25 % margin. |
| Avg Forward Current (IF(AV)) | 5 A - Sustained DC or square-wave current at Tsp ≤ 170 °C on FR4 PCB; enables compact 25–50 W power stages. |
| Forward Voltage (VF) | 425–490 mV @ 5 A, 25 °C - Ultra-low conduction loss reduces heat generation by >30 % vs. standard Schottkys. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB055LAM-40 | 40 V VR, 5 A IF(AV), TO-277 package (3.5 mm height), VF = 450 mV @ 5 A | Larger footprint and height; lower thermal performance (Rth(j-a) ≈ 45 K/W vs. 40 K/W on ceramic) | Choose when board height >0.78 mm is acceptable and cost sensitivity outweighs thermal density requirements. |
| SS54H | 40 V VR, 5 A IF(AV), SMA package, VF = 550 mV @ 5 A, no AEC-Q101 qualification | Higher VF increases conduction loss by ~25 %; lacks automotive stress qualification and guard ring | Acceptable for consumer-grade 24 V adapters where AEC-Q101 and ultra-low VF are not required. |
Compared with RB055LAM-40 and SS54H, PMEG045V050EPDAZ offers superior thermal performance (3 K/W Rth(j-sp)), tighter VR margin (45 V vs. 40 V), AEC-Q101 validation, and lower VF - critical for automotive and high-density industrial power designs where thermal headroom and reliability are constrained.

FAQ
Is PMEG045V050EPDAZ pin-compatible with other CFP15-packaged Schottky diodes?
Yes - PMEG045V050EPDAZ uses the standardized CFP15 (SOT1289) footprint with 1–2–3 anode-anode-cathode pinning. Its dual-anode configuration matches industry-standard layouts for high-current Schottkys, and the solder land pattern aligns with Nexperia's official reflow footprint (7.5 × 4.96 mm). No PCB redesign is needed when substituting within the same package family.
What is the maximum continuous power dissipation at 70 °C ambient on a standard FR4 PCB?
At 70 °C ambient and using a standard FR4 PCB with single-sided 1 oz copper and the recommended footprint, PMEG045V050EPDAZ supports up to 2.15 W continuous power dissipation (per Table 5, condition [2]). This corresponds to ~4.3 A average forward current at 425 mV VF, assuming negligible reverse loss - verified in Figure 9 for δ = 0.5 duty cycle.
Does the integrated guard ring affect PCB layout or thermal design?
No - the guard ring is a monolithic die-level feature and requires no special PCB layout. However, thermal design must prioritize the cathode (Pin 3) tab: a 1 cm² copper pour is mandatory to achieve the rated 3.75 W dissipation. The dual-anode pins (1 and 2) should be routed with equal-length, wide traces to balance current sharing and minimize loop inductance.
Can PMEG045V050EPDAZ be used in reverse polarity protection with 5 A load current?
Yes - with a typical VF of 425 mV at 5 A and 25 °C, voltage drop remains below 0.5 V, preserving >95 % of input voltage for downstream circuitry. At 125 °C junction temperature, VF drops to 340 mV, further improving efficiency. Its 160 A IFSM rating also withstands brief inrush currents during hot-plug events without degradation.
