The Littelfuse SMF4L series TVS diode, part number 31AC6955, is designed for unidirectional voltage transient protection. It features a peak pulse power dissipation of 2000W at an 8/20¬µs waveform and 400W at a 10/1000¬µs waveform, making it suitable for applications requiring robust surge protection. The device has a reverse stand-off voltage of 30V and a maximum clamping voltage of 48.4V, ensuring effective voltage clamping during transient events. This diode is housed in a SOD-123FL package, which is compatible with surface mount technology, optimizing board space. It operates within a temperature range of -55¬8C to 150¬8C and has a low thermal resistance, enhancing its reliability in various environments. The product is RoHS compliant and features a glass passivated junction for improved performance. It is ideal for protecting sensitive electronic components in portable devices, power supplies, and other consumer applications.
The SMF4L series of SOD-123FL small and flat lead lowprofile plastic package is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. 400 W peak pulse power capability at 10/1000μs, repetition rate (duty cycle): 0.01 % Compatible with industrial standard package SOD- 123FL Low inductance, excellent clamping capability For surface mounted applications to optimize board space Typical failure mode is short from over-specified voltage or current Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c IEC-61000-4-2 ESD 30 kV (Air), 30 kV (Contact) ESD protection of data lines in accordance with IEC 61000-4-2 EFT protection of data lines in accordance with IEC 61000-4-4 Fast response time typically below 1 ns from 0 V to Vbrmin
