Product details
Overview
PMEG045V050EPE-QZ from Nexperia is a 45 V, 5 A planar Schottky barrier rectifier in CFP15B (SOT1289B) package, designed for high-efficiency DC-DC conversion and freewheeling in automotive power systems. It delivers typ. 440 mV forward voltage at 5 A and 25 °C, supports 160 A non-repetitive peak forward current, and is qualified to AEC-Q101 for under-hood applications.
For engineers reviewing the PMEG045V050EPE-QZ datasheet, PMEG045V050EPE-QZ pinout, PMEG045V050EPE-QZ application, or PMEG045V050EPE-QZ equivalent, key selection criteria include low VF performance at high ambient temperatures, thermal resistance to solder point (70 K/W), reverse recovery time (13 ns ramp), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Schottky rectifier uses clip-bond technology to achieve low thermal resistance and high power density in a 5.8 × 4.3 × 0.95 mm ultra-thin SMD package. Its planar junction structure enables stable forward voltage across -40 °C to 125 °C operating junction temperature range.
The device exhibits 185 pF diode capacitance at 10 V reverse bias and 540 pF at 1 V, supporting fast switching in OR-ing and reverse polarity protection circuits. Reverse recovery is step- and ramp-defined with trr = 18 ns (step) and 13 ns (ramp), confirming minimal switching loss in high-frequency SMPS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 5 A | 440–490 mV at 25 °C - enables <1.5 W conduction loss in 5 A continuous operation |
| VR | 45 V - supports 36 V automotive battery rail with 25 % margin against load dump transients |
| IF(AV) | 5 A at δ = 0.5, 20 kHz square wave - rated for sustained duty in DC-DC output stages |
| Rth(j-sp) | 70 K/W - low thermal resistance to cathode solder point enables efficient heat transfer to PCB copper |
| trr (ramp) | 13 ns - minimizes reverse recovery charge and EMI in >500 kHz switching converters |

FAQ
What is the maximum junction temperature for continuous operation?
The absolute maximum junction temperature is 175 °C, and the device is rated for continuous operation up to this limit when mounted on an FR4 PCB with a 1 cm² cathode thermal pad. Derating curves in Figures 8–10 confirm 5 A average forward current is sustainable at 100 °C ambient with δ = 0.5 duty cycle.
Does PMEG045V050EPE-QZ support bidirectional current flow?
No - it is a unidirectional Schottky rectifier with anode (Pins 1 & 2) and cathode (Pin 3) terminals. It conducts only from anode to cathode and blocks reverse current up to 45 V. Bidirectional operation would require external circuitry such as back-to-back configuration.
How does the dual-anode pinning improve performance?
Dual anode terminals (Pins 1 and 2) reduce effective series resistance and inductance by providing parallel current paths. This lowers conduction loss and improves thermal distribution across the die, enabling higher surge current handling (160 A IFSM) and more uniform power dissipation.
Can this diode replace a MOSFET-based ideal diode in OR-ing applications?
It serves as a passive alternative - offering simplicity and zero gate drive overhead - but lacks active control. For dynamic OR-ing with voltage monitoring and fast disable, a dedicated ideal diode controller + MOSFET remains necessary. PMEG045V050EPE-QZ excels where low VF and reliability outweigh controllability needs.
