Introduction
The DF2B7AFS is a TVS diode (ESD protection diode) protects semiconductor devices used in mobile device interfaces and other applications to protect against static electricity and noise. Utilizing snapback characteristics, the DF2B7AFS provides low dynamic resistance and superior protective performance. Furthermore, the DF2B7AFS is housed in an ultra-compact package (1.0 mm×0.6 mm) to meet applications that require a small footprint.
Features
- Suitable for use with a 5 V signal line. (VRWM≤5.5 V)
- Protects devices with its high ESD performance. (VESD = ±30 kV (Contact / Air) @IEC61000 - 4 - 2)
- Low dynamic resistance protects semiconductor devices from static electricity and noise. (RDYN = 0.2Ω (typ.))
- Snapback characteristics realizing low clamping voltage protects semiconductor devices. (VC = 11 V @IpP = 4 A (typ.))
- Compact package is suitable for use in high density board layouts such as in mobile devices. SOD - 923: 1.0 mm×0.6 mm size
Applications
- Mobile Equipment
- Smartphones
- Tablets
