Product details
Overview
50WQ06FNTR from Vishay is a surface-mount Schottky rectifier optimized for high-efficiency DC/DC conversion, reverse battery protection, and freewheeling in compact power supplies. It delivers 5.5 A average forward current at 132°C case temperature, 60 V maximum reverse voltage, and 0.54 V forward voltage drop at 5 A and 125°C junction temperature.
For engineers reviewing the 50WQ06FNTR datasheet, 50WQ06FNTR pinout, 50WQ06FNTR application, or 50WQ06FNTR equivalent, key selection criteria include low VF for thermal efficiency, D-PAK (TO-252AA) package compatibility with automated assembly, ruggedness via guard ring design, and suitability for 100 kHz–1 MHz switching topologies in industrial and automotive-grade power systems.
Technical Context
This Schottky rectifier uses a planar epitaxial construction with integrated guard ring to suppress edge breakdown and ensure stable operation up to 150°C junction temperature. Its low 25.5 mΩ forward slope resistance and 360 pF junction capacitance at 5 V support fast recovery and minimal switching loss in synchronous rectification and flyback converters.
The device is rated for 320 A non-repetitive surge current (5 μs sine), exhibits 10,000 V/μs dv/dt capability under rated VR, and maintains ≤35 mA reverse leakage at 125°C - enabling reliable performance in high-dI/dt, high-temperature environments without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 5.5 A at TC = 132°C, 50% duty cycle - supports continuous conduction mode in mid-power SMPS |
| VRRM | 60 V - suitable for 48 V nominal bus systems with 20% transient margin |
| VF @ 5 A, 125°C | 0.54 V - reduces conduction loss by ~35% vs. standard PN diodes at same current |
| IRM @ 125°C | 35 mA - limits standby power loss in battery-fed applications |
| RthJC | 3.0 °C/W - enables direct heatsinking to PCB copper pour for passive thermal management |
| CT @ 5 V | 360 pF - minimizes capacitive turn-on loss in high-frequency (>500 kHz) topologies |
| dv/dt Rating | 10,000 V/μs - withstands fast-switching SiC/GaN gate driver transients without false triggering |
Pinout & Package
D-PAK (TO-252AA) surface-mount package with exposed drain pad for thermal enhancement; 3-terminal configuration: Anode (Pin 1 & 4), Cathode (Pin 3), Base (Pin 2, electrically connected to cathode and thermal pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pins 1, 4) | Current entry point | Parallel anode connections reduce bondwire inductance and improve surge current sharing |
| Cathode (Pin 3) | Current exit point | Primary cathode terminal; ties directly to internal die cathode metallization |
| Base (Pin 2) | Thermal & electrical tie | Exposed metal pad soldered to PCB ground plane for thermal dissipation and low-inductance return path |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Prevents premature edge breakdown under high dv/dt and elevated TJ, extending lifetime in harsh environments |
| Low VF slope resistance | 25.5 mΩ enables predictable linear conduction loss modeling across load range |
| High-frequency operation | No minority-carrier storage delay - supports zero-voltage switching (ZVS) and resonant topologies |
| Reverse battery protection ready | Rated for 60 V reverse blocking with <35 mA leakage at 125°C - prevents system damage during polarity reversal |
| AEC-Q101 qualified | Validated for automotive powertrain and body electronics per stress test requirements |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS5L60SF | Same 60 V VRRM, 5 A IF(AV), but TO-277 package (no thermal pad); VF = 0.58 V @ 5 A, 125°C | Limited thermal performance due to higher RthJA; unsuitable for sustained >3 A operation without forced air | Select when board space is constrained and thermal budget allows 0.04 V higher VF penalty |
| ON Semi MBR560FCT | 60 V VRRM, 5 A IF(AV), D2PAK package; VF = 0.62 V @ 5 A, 25°C (degrades to ~0.69 V @ 125°C) | Higher VF drift with temperature reduces efficiency margin in high-ambient environments | Prefer for legacy D2PAK footprint compatibility where 5.5 A rating is not required |
Compared with STPS5L60SF and MBR560FCT, the 50WQ06FNTR offers superior thermal resistance (3.0 °C/W vs. ≥5.5 °C/W), lower VF at elevated temperature, and AEC-Q101 qualification - making it optimal for thermally dense, automotive-qualified, or high-reliability industrial power stages.

FAQ
What is the maximum junction temperature rating for the 50WQ06FNTR?
The 50WQ06FNTR has a maximum junction temperature (TJ) rating of 150°C, verified per Absolute Maximum Ratings in Vishay Bulletin PD-20525 rev. G. This allows continuous operation in high-ambient environments such as under-hood automotive modules or enclosed industrial power supplies, provided thermal design maintains TJ ≤ 150°C using the specified RthJC of 3.0 °C/W.
Does the 50WQ06FNTR have AEC-Q101 qualification?
Yes, the 50WQ06FNTR is explicitly qualified to AEC-Q101 standards, as confirmed in the Vishay datasheet (Bulletin PD-20525 rev. G, page 7). This qualification covers stress testing for temperature cycling, humidity bias, high-temperature operating life, and ESD - validating its suitability for automotive powertrain and body electronics applications.
What is the thermal resistance from junction to case (RthJC) for the 50WQ06FNTR?
The 50WQ06FNTR has a maximum thermal resistance of 3.0 °C/W from junction to case under DC operation, per Figure 4 and Thermal-Mechanical Specifications in the official datasheet. This value assumes full soldering of the exposed base pad (Pin 2) to a minimum 1-inch² copper area on the PCB, enabling efficient heat transfer to the board.
How does the forward voltage drop of the 50WQ06FNTR vary with temperature?
The 50WQ06FNTR exhibits a negative temperature coefficient for VF: it drops from 0.57 V at 25°C to 0.54 V at 125°C (measured at 5 A). This behavior - confirmed in Figure 1 of the datasheet - improves conduction efficiency at elevated temperatures, reducing thermal runaway risk compared to PN diodes with positive VF drift.
Is the 50WQ06FNTR compatible with lead-free reflow soldering processes?
Yes, the 50WQ06FNTR is rated for lead-free reflow soldering per JEDEC J-STD-020. Its package construction and internal metallization support peak reflow temperatures up to 260°C for 30 seconds, consistent with standard Pb-free assembly profiles. The device marking "FN" in the ordering code also indicates TO-252AA packaging with lead-free finish compliance.
