The SZ1SMB series TVS diode, specifically part number 27AK1599, is designed for transient voltage suppression in various applications. It features a peak power dissipation of 600W at a pulse width of 1 ms and a reverse standoff voltage of 12V. The maximum clamping voltage is rated at 19.9V, making it suitable for protecting sensitive components from high voltage transients. This unidirectional diode operates within a temperature range of -65¬8C to +150¬8C and has a fast response time of less than 1 ns. It is compliant with AEC-Q101 standards, making it suitable for automotive applications. The device is packaged in a DO-214AA (SMB) case style and is RoHS compliant. Its low leakage current of less than 5.0 ¬µA above 10V enhances its reliability in various electronic circuits.
The SZ1SMB series is designed to protect voltage sensitive components from high voltage, high energy transients. They have excellent clamping and high surge capability, as well as fast response time. The SZ1SMB series is supplied in the Littelfuse exclusive, cost-effective, highly reliable package and is ideally suited for use in communication systems, automotive, numerical controls, process controls, medical equipment, business machines, power supplies and many other industrial and consumer applications. Zener Transient Overvoltage Suppressors Working Peak Reverse Voltage Range − 5.0 V to 170 V for uni-directional, and 10 V to 75 V for bi-directional Standard Avalanche Breakdown Voltage Range −6.4 V to 209 V for uni-directional, 11.1 V to 92.07 V for bi-directional Peak Power rating of 600 W at 1 Ams ESD Rating of Class 3 (>16 kV) per Human Body Model Maximum Clamp Voltage at Peak Pulse Current Low Leakage < 5.0 μA Above 10 V Intended for UL 497B Type Protection Response Time Is Typically Below 1 ns Lead-free means second level interconnect contains no lead and the terminal finish material is tin (per IPC/JEDEC J-STD-609A.01).)
