Product details
Overview
PMEG045V050EPDZ from Nexperia is a 45 V, 5 A low forward voltage MEGA Schottky barrier rectifier in a CFP15 (SOT1289) surface-mount package, featuring integrated guard ring stress protection and clip-bonding thermal enhancement. It delivers 425–490 mV forward voltage at 5 A and 25 °C, supports 160 A non-repetitive peak forward current, and is AEC-Q101 qualified for automotive-grade reliability in DC-DC converters and freewheeling paths.
For engineers reviewing the PMEG045V050EPDZ datasheet, PMEG045V050EPDZ pinout, PMEG045V050EPDZ application, or PMEG045V050EPDZ equivalent, key selection criteria include its ultra-low VF at high current, 0.78 mm profile for space-constrained power stages, thermal resistance as low as 3 K/W to solder point, and validated performance under pulsed and continuous duty cycles up to δ = 1.
Technical Context
This Schottky rectifier uses planar MEGA technology with an integrated guard ring to suppress edge breakdown and improve surge robustness. Its clip-bonded construction directly connects the die to the cathode tab, enabling efficient heat transfer to PCB copper or heatsinks.
It exhibits step-recovery trr of 19 ns and ramp-recovery trr of 12 ns at 25 °C, with diode capacitance of 580 pF at 1 V reverse bias - optimized for high-frequency switching in synchronous rectification and flyback topologies where low recovery loss and minimal ringing are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 5 A | 425–490 mV at 25 °C; enables <1.5 W conduction loss in 12 V output rails at full load |
| VR | 45 V maximum reverse voltage; suitable for 36 V nominal automotive and industrial bus systems |
| IF(AV) | 5 A average forward current; rated for continuous operation with δ = 0.5 square wave at Tsp ≤ 170 °C |
| IFS M | 160 A non-repetitive peak forward current; withstands short-circuit transients in SMPS primary-side clamping |
| Rth(j-sp) | 3 K/W junction-to-solder-point; allows >3.75 W total power dissipation on ceramic PCB with proper cathode pad layout |
| trr (step) | 19 ns reverse recovery time; minimizes switching loss and EMI in 500 kHz–1 MHz DC-DC converters |
| AEC-Q101 | Qualified per Automotive Electronics Council standard; validated for temperature cycling, HTRB, and ESD robustness |
Pinout & Package
The device is housed in a thermally enhanced CFP15 (SOT1289) plastic SMD package measuring 5.8 × 4.3 × 0.78 mm, with exposed cathode tab for direct thermal coupling to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary anode connection; paralleled with Pin 2 for lower inductance and higher current handling |
| 2 | Anode | Secondary anode terminal; dual-anode configuration reduces series resistance and improves thermal symmetry |
| 3 | Cathode | Exposed metal tab serving as cathode and primary thermal path; must be soldered to ≥1 cm² copper area for rated power |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 425 mV typ. at 5 A/25 °C - reduces conduction loss by ~30% vs. standard Schottkys in 5–12 V outputs |
| Guard ring integration | Planar edge termination prevents premature avalanche at high dv/dt - critical for reverse polarity protection circuits |
| Clip-bonding | Direct die-to-tab interconnect lowers thermal resistance by 60% vs. wire-bonded equivalents in same footprint |
| Thin profile | 0.78 mm max height - enables use in ultra-low-profile power modules and stacked PCB assemblies |
| AEC-Q101 qualification | Validated for automotive under-hood environments including 1000-cycle temperature cycling (-40 °C to +150 °C) |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0540HT1G | 40 V VR, 5 A IF(AV), VF = 450 mV @ 5 A, SOD-123FL package (1.7 mm height) | Larger height and lower VR limit suitability for 36 V bus systems | Select when board height >0.8 mm is acceptable and VR margin <10 V suffices |

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature is 175 °C, but continuous operation is limited by solder point temperature (Tsp ≤ 170 °C) and ambient conditions. At δ = 0.5 square wave, the device sustains 5 A average forward current up to 100 °C ambient on FR4 with 1 cm² cathode pad - verified per Table 8 limiting values and Figure 10 thermal derating curves.
How does the dual-anode pin configuration affect PCB layout?
Pins 1 and 2 are internally connected anodes, allowing parallel routing to reduce trace inductance and shared current sharing. Layout must maintain equal trace length and width to both pins; asymmetric routing risks current imbalance and localized heating. The cathode (Pin 3) requires a dedicated thermal pad with ≥1 cm² copper area for rated power dissipation.
Is PMEG045V050EPDZ suitable for reverse polarity protection in 24 V systems?
Yes - with 45 V VR rating and AEC-Q101 qualification, it reliably blocks reverse input up to –24 V while conducting forward current with only 425 mV drop at 5 A. Its guard ring prevents edge breakdown during fast polarity reversals, and the 160 A IFSM handles inrush surges during hot-plug events common in industrial 24 V systems.
What is the recommended reflow profile for CFP15 (SOT1289) mounting?
Per Nexperia's SOT1289 footprint guidelines (Fig. 18), use a standard lead-free reflow profile with peak temperature ≤ 260 °C, 60-second duration above 217 °C, and controlled ramp rates (<3 °C/s). The cathode tab must achieve full wetting; insufficient solder volume or voiding degrades thermal performance and may trigger early thermal runaway under high δ conditions.
