Overview
The SMBJ series is designed to protect sensitive electronic equipment from voltage transients caused by lightning strikes and other transient voltage events.
Applications
- TVS components are ideal for protecting I/O interfaces, Vcc buses, and other vulnerable circuits in telecommunications, computer, industrial, and consumer electronics applications.
Key features
- 600 W peak pulse power capability at 10/1000 μs waveform, repetition rate (duty cycle): 0.01%
- Surface mount package for optimized board space
- Low dynamic resistance
- Typical failure mode: short circuit due to overvoltage or overcurrent
- IEC-61000-4-2 ESD 30 kV (air discharge), 30 kV (contact discharge)
- ESD protection for data lines per IEC 61000-4-2
- Whisker tested per JEDEC JESD201A Tables 4a and 4c, passes Level 1 and Level 2
- VBR @ TJ = VBR @ 25
- Cx(1 + αTx(TJ - 25)) (αT: temperature coefficient, typical value 0.1%)
- UL-recognized compound, meets V-0 flammability rating
- Matte tin lead-free plating
- Halogen-free and RoHS compliant
- Lead-free E3 denotes second-level interconnect lead-free, terminal finish material: tin (Sn) (IPC/JEDEC J-STD-609A.01)
- UL 497B recognized as isolating loop circuit protector
- Products manufactured outside China are available (parts with E suffix). Refer to the "Ordering and Packaging Options" section for details
