Ftd02p Datasheet | UPDATED — WORKFLOW |

| Parameter | Test Condition | Min | Typ | Max | Unit | | :--- | :--- | :--- | :--- | :--- | :--- | | Forward Voltage (( V_F )) | ( I_F = 1.0A ) | - | - | 1.0 | V | | Reverse Leakage Current (( I_R )) | ( V_R = 200V ), TA=25°C | - | - | 5 | µA | | Reverse Leakage Current (( I_R )) | ( V_R = 200V ), TA=100°C | - | - | 100 | µA | | Reverse Recovery Time (( t_rr )) | ( I_F = 0.5A, I_R = 1.0A, I_rec=0.25A ) | - | - | 50 | ns |

Crucial Note: A ( t_rr ) of 50ns (or less) indicates the Ftd02p is a Fast Recovery Diode (not a standard 2-4µs rectifier). This makes it suitable for high-frequency switching circuits (e.g., SMPS output stages or flyback clamps).

To help you decide if the Ftd02p is right for your project, here is a comparison table against common competitors. Ftd02p Datasheet

| Parameter | Ftd02p | 1N4002 (Standard) | 1N5819 (Schottky) | UF4002 (Ultrafast) | | :--- | :--- | :--- | :--- | :--- | | Forward Current | 2.0A | 1.0A | 1.0A | 1.0A | | Reverse Voltage | 200V | 100V | 40V | 100V | | Recovery Time | 50ns | 30µs | <1ns (no recovery) | 50ns | | Forward Voltage @ 1A | 0.85V | 1.1V | 0.45V | 1.0V | | Best For | 2A, 200V SMPS | 50/60Hz line | Low voltage, high efficiency | 1A ultrafast switching |

Verdict: Upgrade from 1N4002 for high frequency. Upgrade from 1N5819 for higher voltage. The Ftd02p fills the gap where a Schottky cannot survive the voltage, but a standard rectifier is too slow. | Parameter | Test Condition | Min |

Exceeding these values will destroy the component.

Key Insight: The Ftd02p is rated for 200V and 1A average current. The surge rating of 30A makes it robust for capacitive load startups.

The FT02P features a standardized Gravity interface (PH2.0 connector) as well as standard header pins for flexibility.
