1N4447 Description

Short technical summary and product information.

The 1N4447 is a small signal diode manufactured by On Semiconductor (onsemi). It is designed for general purpose rectification and switching applications. Key electrical specifications include a maximum repetitive reverse voltage of 100V, an average rectified forward current of 200mA, and a forward voltage of 1.0V at 20mA.

 

The diode offers a fast reverse recovery time of 4.0ns under test conditions (IF=10mA, VR=6V, Irr=1mA, RL=100Ω), making it suitable for high-speed switching. It has a low reverse leakage current of 25nA at 20V and a total capacitance of 2.0pF. The device can handle a non-repetitive peak forward surge current of 1.0A for a 1-second pulse.

 

Thermal characteristics include a power dissipation of 500mW and a junction-to-ambient thermal resistance of 300°C/W. The operating junction temperature range is up to 175°C, with storage temperature from -65°C to +200°C.

 

The 1N4447 is available in a through-hole DO-35 (DO-204AH) axial lead package. It is lead-free and halogen-free compliant as verified by the datasheet. The standard packaging is bulk bag with 5000 pieces.
