Tiny ESD protection diodes provides high surge capability

November 26, 2013 // By Paul Buckley
Vishay Intertechnology has a series of surface-mount ESD protection diodes in the low-profile SMF package. For portable electronics, SMFxxA series devices provide high surge capability of 200W at 10/1000 μsec.

With their low 1-mm profile, 'Low-Noise' technology, and fast response times, the devices are suitable for line transient voltage protection in space-constrained designs.

The SMFxxA series consists of 32 devices with working voltages from 5 to 58V. The devices offer a peak pulse current from 2.1A to 21.7A, clamping capability from 9.2 to 95V, low incremental surge resistance, and operating temperatures from -55°C to +150°C.

The protection diodes provide ESD capability of ±30 kV (air and contact discharge) in accordance with IEC 61000-4-2, support high-temperature soldering to 260°C / 10 sec at their terminals, and meet the MSL Level 1 standard per J-STD-020. The devices are RoHS-compliant, halogen-free, and Vishay Automotive Grade.
