Product details
Overview
PMEG040V030EPDZ from Nexperia is a 40 V, 3 A low forward-voltage Schottky barrier rectifier in a CFP15 (SOT1289) thermally enhanced SMD package, featuring integrated guard ring stress protection and AEC-Q101 qualification for automotive use. It delivers VF = 425–490 mV at IF = 3 A and IR ≤ 120 µA at VR = 40 V, enabling high-efficiency low-voltage rectification in space-constrained power stages.
For engineers reviewing the PMEG040V030EPDZ datasheet, PMEG040V030EPDZ pinout, PMEG040V030EPDZ application, or PMEG040V030EPDZ equivalent, key selection criteria include ultra-low VF for minimal conduction loss, 175 °C junction rating for thermal robustness, clip-bonded construction for high power capability, and AEC-Q101 compliance for automotive-grade reliability.
Technical Context
This MEGA Schottky rectifier uses planar silicon technology with an integrated guard ring to suppress edge breakdown and improve surge robustness. Its clip-bonding interconnect and exposed cathode tab reduce thermal resistance to Rth(j-sp) = 3 K/W, supporting high pulsed currents up to IFSM = 120 A.
The device exhibits fast recovery (trr ≤ 13 ns) and low capacitance (Cd = 130 pF at VR = 10 V), making it suitable for high-frequency switching topologies. Reverse leakage remains tightly controlled across temperature - IR = 32–120 µA at VR = 40 V and Tj = 25 °C, rising to 18 mA at Tj = 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 40 V - Maximum DC blocking voltage; defines safe operating range in reverse-biased freewheeling or polarity protection roles. |
| IF(AV) (Avg. Forward Current) | 3 A - Continuous square-wave current handling at δ = 0.5, f = 20 kHz, Tsp ≤ 167 °C; supports sustained power delivery in compact DC/DC converters. |
| VF (Forward Voltage) | 425–490 mV at IF = 3 A, Tj = 25 °C - Ultra-low conduction loss reduces heat generation and improves system efficiency in low-voltage rails. |
| IR (Reverse Current) | 32–120 µA at VR = 40 V, Tj = 25 °C - Low leakage preserves battery life and minimizes standby power in always-on automotive modules. |
| Rth(j-sp) (Junction-to-Solder-Point) | 3 K/W - Exceptionally low thermal resistance enables direct heat transfer from die to PCB copper, critical for thermal management in dense layouts. |
| trr (Reverse Recovery Time) | ≤13 ns - Fast step-recovery behavior limits switching losses and EMI in high-frequency SMPS and synchronous rectifier applications. |
| AEC-Q101 Qualified | Yes - Validated for automotive under stress test conditions including HTGB, HTRB, and temperature cycling; supports functional safety-aware designs. |
Pinout & Package
Encapsulated in a thermally enhanced CFP15 (SOT1289) surface-mount plastic package measuring 5.8 × 4.3 × 0.78 mm, with exposed cathode pad for optimal heat dissipation and standard FR4-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Dual-anode configuration (pins 1 and 2 tied internally); enables parallel routing for lower inductance and higher current density layout. |
| 2 | Anode | Second anode terminal - electrically identical to pin 1; used for symmetric PCB trace routing and improved thermal symmetry. |
| 3 | Cathode | Exposed metal tab - primary thermal path to PCB; must be soldered to ≥1 cm² copper area to achieve rated Rth(j-sp) = 3 K/W. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 425–490 mV @ 3 A ensures <1.5 W conduction loss at full load, reducing heatsink requirements in 5–12 V output rails. |
| Guard ring integration | Planar MEGA structure with built-in guard ring suppresses edge avalanche, improving long-term reliability under repetitive surge stress. |
| Clip-bonded construction | Eliminates wire bonds; increases current capacity and thermal conductivity while lowering parasitic inductance vs. traditional SOD packages. |
| Thin-profile SMD | 0.78 mm max height enables use in ultra-low-profile automotive ECUs and portable industrial controllers where Z-height is constrained. |
| AEC-Q101 qualification | Validated for automotive ambient temperatures (−40 °C to +175 °C) and mechanical stress, supporting ASIL-B compatible subsystems. |

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 NSS40300DS | Same VR = 40 V, IF(AV) = 3 A, but VF = 490–550 mV (higher); TO-252 package (larger footprint, higher Rth(j-a)). | Lacks AEC-Q101 qualification; not validated for automotive temperature cycling or humidity testing. | Prefer for cost-sensitive industrial non-automotive use where thermal margin exists and qualification is not required. |
| Vishay VSK340A | VR = 40 V, IF(AV) = 3 A, VF = 430–500 mV; same CFP15 footprint but no guard ring; Rth(j-sp) = 4.5 K/W (higher). | Not AEC-Q101 qualified; higher IR (up to 200 µA) reduces battery-life suitability in always-on nodes. | Acceptable for consumer-grade DC/DC where surge immunity and long-term leakage stability are secondary concerns. |
Compared with NSS40300DS and VSK340A, PMEG040V030EPDZ offers superior thermal performance (Rth(j-sp) = 3 K/W), guaranteed AEC-Q101 compliance, and lower typical VF - making it the preferred choice for automotive and thermally constrained industrial applications demanding reliability and efficiency.

FAQ
What is the maximum allowable solder point temperature for PMEG040V030EPDZ during reflow?
The device supports standard lead-free reflow profiles with peak solder point temperature up to 260 °C for ≤30 seconds, per J-STD-020. The cathode tab must be fully soldered to a ≥1 cm² copper area to maintain thermal integrity and avoid exceeding Tsp = 167 °C during operation.
Does PMEG040V030EPDZ support bidirectional current flow?
No - it is a unidirectional Schottky rectifier. Current flows only from anode (pins 1 and 2) to cathode (pin 3). Reverse conduction is blocked up to VR = 40 V, and the device is not rated for reverse bias beyond that limit.
How does the dual-anode configuration affect PCB layout?
The dual-anode design allows symmetric trace routing from both pins 1 and 2 to the input node, reducing loop inductance and improving current sharing. It also enables placement flexibility when routing around adjacent components or thermal pads on dense automotive PCBs.
Is PMEG040V030EPDZ suitable for synchronous rectification circuits?
No - it is a passive Schottky rectifier, not a synchronous rectifier controller or MOSFET driver. However, its low VF and fast trr make it an excellent replacement for standard diodes in asynchronous rectification stages where gate drive complexity must be avoided.
