1N457TR Description

Short technical summary and product information.

The 1N457TR is a small signal diode from onsemi, designed for general purpose rectification and signal switching applications. It features a maximum repetitive reverse voltage of 70V and an average rectified forward current of 200mA. Forward voltage is typically 1V at 20mA, and reverse leakage current is only 25nA at 60V. Total capacitance is 8pF at 0V and 1MHz, supporting high-frequency operation.

 

Power dissipation is rated at 500mW with a junction-to-ambient thermal resistance of 300°C/W. The device can operate at junction temperatures up to 175°C and is stored between -65°C and +200°C. It is supplied in a through-hole DO-204AH (DO-35) package with axial leads, suitable for manual assembly and prototyping.

 

Standard packaging is bulk with 5000 units, and tape & reel options are available. Typical applications include low current rectification, signal detection, voltage clamping, and reverse polarity protection.
