Product details
Overview
PMEG030V030EPE-QZ from Nexperia is a 30 V, 3 A planar low forward voltage Schottky barrier rectifier in a CFP15B (SOT1289B) surface-mount package, designed for high-efficiency DC-to-DC conversion and freewheeling in automotive power supplies. It delivers 400 mV typical forward voltage at 3 A and 25 °C, supports 120 A non-repetitive peak forward current, and is qualified to AEC-Q101 for under-hood applications.
For engineers reviewing the PMEG030V030EPE-QZ datasheet, PMEG030V030EPE-QZ pinout, PMEG030V030EPE-QZ application, or PMEG030V030EPE-QZ equivalent, key selection criteria include ultra-low VF performance, thermal resistance of 3 K/W (junction-to-solder point), reverse recovery time ≤16 ns, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Schottky rectifier uses planar die construction with clip-bond interconnect technology to minimize parasitic resistance and enhance thermal conduction from junction to solder point. Its dual-anode configuration (Pins 1 & 2) and single cathode (Pin 3) enable low-inductance, high-current routing in compact layouts.
The device operates with no minority-carrier storage, delivering near-zero reverse recovery charge (Qrr) and enabling high-frequency switching up to 20 kHz square-wave operation. Junction temperature is rated to 175 °C, with thermal resistance Rth(j-sp) = 3 K/W when mounted on a 1 cm² cathode pad - critical for sustained 3 A average current in constrained automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 3 A | 400–450 mV at 25 °C - enables >95% efficiency in 3.3 V/5 V buck converters |
| VR | 30 V maximum reverse voltage - suitable for 24 V automotive systems with transient margin |
| IF(AV) | 3 A average forward current - supported at Tsp ≤ 173 °C with 0.5 duty cycle, 20 kHz |
| trr | ≤16 ns step recovery - minimizes switching loss and EMI in high-frequency SMPS |
| Rth(j-sp) | 3 K/W - enables direct thermal coupling to PCB copper, reducing thermal derating |
| IR @ 30 V | 45–150 µA at 25 °C - low leakage preserves battery life in always-on modules |
| Qrr | Not specified - inherent Schottky behavior eliminates stored charge, eliminating tail current |
Pinout & Package
Encapsulated in a thermally enhanced CFP15B (SOT1289B) plastic SMD package: 5.8 × 4.3 × 0.95 mm body, 2.13 mm lead pitch, ultra-thin profile optimized for high-power density layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary anode connection; electrically tied to Pin 2 for parallel current sharing |
| 2 | Anode | Secondary anode; dual-anode structure reduces effective series resistance by ~30% |
| 3 | Cathode | Thermally and electrically dominant terminal; large tab provides low Rth(j-sp) = 3 K/W |
Key Features
| Feature | Design Value |
|---|---|
| Very low VF | 400 mV typ. @ 3 A, 25 °C - reduces conduction loss by ≥40% vs. standard Schottkys |
| Clip-bond construction | Enables 4.2 A DC forward current rating and 120 A IFSM - supports surge-tolerant designs |
| AEC-Q101 qualified | Validated for automotive under-hood use including temperature cycling, HTRB, and ESD |
| Ultra-thin SMD package | 0.95 mm max height - fits beneath low-profile heatsinks and in space-constrained ECUs |

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-3EY30-M3/54 | 30 V, 3 A; VF = 490 mV @ 3 A; TO-277A package; Rth(j-a) = 50 K/W | Larger footprint; higher VF increases conduction loss by 0.27 W at 3 A | Prefer when legacy TO-277A footprint compatibility is required over thermal performance |
| ON Semiconductor NSR3030HT1G | 30 V, 3 A; VF = 420 mV @ 3 A; SOD-123FL; Rth(j-a) = 110 K/W; no AEC-Q101 | Smaller package but lacks automotive qualification and thermal capability for sustained 3 A | Acceptable for consumer-grade 3 A applications below 85 °C ambient, not for automotive |
Compared with VS-3EY30-M3/54 and NSR3030HT1G, PMEG030V030EPE-QZ offers the lowest VF, best thermal resistance (Rth(j-sp) = 3 K/W), and only AEC-Q101-qualified option - making it the sole choice for thermally demanding, safety-critical automotive 3 A rectification.

FAQ
What is the maximum continuous forward current for PMEG030V030EPE-QZ at 100 °C ambient?
At Tamb = 100 °C on an FR4 PCB with 1 cm² cathode pad, PMEG030V030EPE-QZ supports 2.1 A average forward current (δ = 0.5, f = 20 kHz), per Figure 9. This derating ensures junction temperature remains ≤175 °C with adequate thermal margin.
Does PMEG030V030EPE-QZ have a specified reverse recovery charge (Qrr)?
No - as a Schottky barrier rectifier, PMEG030V030EPE-QZ exhibits majority-carrier conduction with no minority-carrier storage. Therefore, Qrr is effectively zero, eliminating reverse recovery losses and associated EMI in high-frequency switching applications.
Can PMEG030V030EPE-QZ be used in a 48 V automotive system?
No - its absolute maximum reverse voltage is 30 V. Applying 48 V exceeds rating and risks catastrophic failure. For 48 V systems, consider Nexperia's PMEG045V030EPK-Q (45 V VR) or equivalent 60 V-rated Schottkys with appropriate derating.
What is the recommended reflow profile for CFP15B (SOT1289B) package mounting?
Nexperia specifies a peak reflow temperature of 260 °C for 10–20 seconds, with stencil thickness of 0.125 mm and solder paste volume calibrated to the footprint in Figure 16. Preheat ramp rate must not exceed 3 °C/s to avoid package delamination or solder voiding.
