1N6373 Description

Short technical summary and product information.

The 1N6373 is a unidirectional Zener transient voltage suppressor from On Semiconductor designed to protect sensitive electronic components from high-voltage, high-energy transients. With a peak pulse power rating of 1500 watts (1 ms), it provides robust clamping performance. The device features a reverse standoff voltage of 5V and a maximum clamping voltage of 9.4V, ensuring fast and effective suppression.

 

Key electrical characteristics include an ESD rating of Class 3 (>16 kV) per the Human Body Model, a typical response time of less than 1 nanosecond, and a maximum forward surge current of 200 A. The device also offers a steady state power dissipation of 5 watts (lead length 3/8", TL ≤75°C) and a thermal resistance junction-to-lead of 20 °C/W.

 

The 1N6373 comes in the void-free, transfer-molded, thermosetting plastic DO-201AD axial leaded package (Case 41A). It is through-hole mountable and has a cathode band for polarity identification. The operating temperature range spans -65°C to 175°C (junction temperature), making it suitable for a wide variety of industrial and communication applications.
