5pcs FR207 Diode

🔹 5PCS FR207 – 2A 1000V Fast Recovery Rectifier Diode

A high-efficiency, fast recovery rectifier diode designed for switching power supplies, inverters, and other high-frequency applications. The FR207 offers improved switching performance and reduced reverse recovery time compared to standard 1N5408 diodes, making it ideal for modern electronic circuits.

✅ Specifications:

• Part Number: FR207

• Type: Fast Recovery Rectifier Diode

• Max Repetitive Reverse Voltage (VRRM): 1000V

• Max Average Forward Rectified Current (IO): 2A

• Peak Forward Surge Current (IFSM): 70A (8.3ms single half-sine wave)

• Forward Voltage (VF): ~1.3V (Max at 2A)

• Reverse Recovery Time (trr): 500 ns (Typical) – Key fast recovery spec

• Package: DO-15 (Axial Lead, slightly smaller than DO-201AD)

• Lead Material: Tinned Copper

• Quantity: 5 pieces

⚙️ Key Features:

• Fast Recovery: The 500ns trr minimizes switching losses and noise in high-frequency circuits like switch-mode power supplies (SMPS).

• High Voltage & Current Rating: Robust 1000V / 2A rating suitable for offline power applications.

• Glass Passivated Junction: Ensures high reliability and stable performance under varying temperatures.

• Low Leakage Current: Improves efficiency in standby or low-power modes.

• Clearly Marked Polarity: Cathode band is distinct for easy circuit assembly.

📦 Typical Applications:

• Switch-Mode Power Supplies (SMPS): Used as the output rectifier in flyback, forward, and boost converters (e.g., PC power supplies, phone chargers).

• Freewheeling / Snubber Diodes: Critical in circuits with inductive loads (motor drives, relay controllers) to clamp voltage spikes and protect transistors/MOSFETs.

• High-Frequency Rectification: Inverters, UPS systems, and induction heating equipment where standard diodes would overheat.

• Reverse Polarity Protection: Effective protection in medium-current DC circuits.

• DIY & Repair: Essential for fixing or modifying modern electronic devices that operate at higher frequencies.

🔧 Polarity & Usage Notes:

• Cathode (-) End: Marked with a black or grey band around one end of the diode body.

• Anode (+) End: The unmarked end.

• Current Flow: From Anode (no band) to Cathode (banded end).

• Heatsinking: For continuous 2A operation, attach to a heatsink or use adequate PCB copper area to dissipate heat (~2.6W power loss).

• Replacement Tip: Can often replace slower 1N4007/1N5408 diodes in switching circuits for better performance, but check the forward voltage and current requirements.

⚠️ Important Considerations:

• Forward Voltage: Slightly higher (~1.3V) than standard diodes, which may affect very low-voltage circuits.

• Surge Current: Lower than 1N5408 diodes (70A vs 200A). Consider this for high-inrush applications.

• Frequency Advantage: Its main benefit is in circuits operating above 1 kHz. For 50/60Hz mains rectification, a standard 1N5408 may be more cost-effective.
