Product Description

The SMF24A from Littelfuse is a SMF series 200W unidirectional transient voltage suppression diode in SOD-123FL package. The SMF series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. SMF package is 50% smaller in footprint when compare to SMA package and delivering one of the low height profiles (1.1mm) in the industry. SMF devices are ideal for the protection of I/O interfaces, VCC bus and other vulnerable circuit.
Reverse stand off voltage VR is 24V
Breakdown voltage VBR is 26.7V minimum and 29.5V maximum at 1mA
Maximum reverse leakage is 1µA
Maximum clamping voltage VC is 38.9V
Maximum peak pulse current is 5.1A
Operating temperature range from -65°C to +175°C, IEC-61000-4-2 ESD 30KV (air), 30KV (contact)
ESD protection of data lines with IEC 61000-4-2 and EFT protection with IEC 61000-4-4 standard
Low inductance, excellent clamping capability
Typical failure mode is short from over specified voltage or current
Built-in strain relief
