Product Description
Bourns CDSOD323-T03 is a high-performance 1-element uni-directional Transient Voltage Suppression (TVS) diode, designed to safeguard electronic circuits against voltage surges and transient spikes. Featuring a peak pulse power dissipation capability of 350 W and packaged in a compact 2-pin SOD-323 surface mount package, this diode is optimized for space-sensitive high-reliability applications.
The diode exhibits a stand-off voltage of 3.3V and a minimum breakdown voltage of 4V, with a maximum peak pulse current rating of 20A, making it effective for transient suppression in demanding environments. Its low typical capacitance of approximately 3pF ensures minimal signal distortion, ideal for high-frequency data lines and sensitive electronics.
Operating temperature range spans from -55°C to 150°C, supporting robust performance across harsh industrial, consumer electronics, and communication device conditions. The device fully protects one line or I/O port and is compliant with ESD standards including IEC 61000-4-2, IEC 61000-4-4, and IEC 61000-4-5, providing effective electrostatic and electrical fast transient protection.
Physically, the diode measures 1.9mm in length, 1.45mm in width, and 1.01mm in height, fitting compact PCB layouts and enabling automated assembly with standard pick and place machinery. It replaces 0805 MLV devices offering a more efficient and reliable alternative in power transient suppression.
Suitable applications include cellular phones, digital cameras, MP3 players, GPS devices, PDAs, notebooks, and USB interface circuits where board-level transient protection enhances device longevity and reliability.
Low capacitance of approximately 3pF typical minimizes signal interference. Peak pulse power dissipation of 350 W supports high energy transient suppression. Maximum peak pulse current of 20A ensures robust overvoltage handling capability.
Compact surface mount SOD-323 package enables space saving and efficient manufacturing. Operates in a wide temperature range from -55°C to 150°C for varied environments. Compliant with multiple IEC standards ensuring electrical and ESD protection.
Designed for protection of single line or I/O port circuits in consumer and industrial electronics. Discover the Bourns range of TVS Diodes at EnvMart for trusted protection solutions in electronics manufacturing and design.
