SMX1J

SMX1J Transil™ Features ■ A Peak pulse power: – 85 W (10/1000 µs) – 800 W (8/20 µs) Stand off voltage 7.5 V Unidirectional Low leakage current: – 1 µA at 25 °C – 2 µA at 85 °C Operating Tj max: 150 °C High power capability at Tjmax: 78 W K ■ ■ ■ µQFN 2L Figure 1. Functional diagram (top view) ■ ■ Complies with the following standards ■ IEC 61000-4-2 level 4 – 15 kV (air discharge) – 8 kV (contact discharge) MIL STD 883G - Method 3015-7 Class 3B – 25 kV HBM (human body model) ■ Description The SMX1J7.5A www.DataSheet4U.com Transil has been designed to protect sensitive equipment against electro-static discharges according to IEC 61000-4-2, MIL STD 883 Method 3015, and electrical over stress such as IEC 61000-4-4 and 5. They are generally for surges below 85 W 10/1000 µs. The Planar technology makes it compatible with high-end equipment and SMPS where low leakage current and high junction temperature are required to provide reliability and stability over time. The SMX1J7.5A is packaged in µQFN 2 leads. TM: Transil is a trademark of STMicroelectronics November 2009 Doc ID 16180 Rev 2 1/11 www.st.com 11 Characteristics SMX1J 1 Table 1.
