Overview of SMF4L5.0A by Littelfuse Inc.

The Littelfuse SMF4L5.0A is a Trans Voltage Suppressor Diode specifically designed to protect sensitive electronic circuits from voltage transients. This device features a reverse stand-off voltage (V_RWM) of 5V, making it suitable for applications where this specific voltage level is critical. The part is unidirectional, meaning it allows current to flow in only one direction, which is essential for mitigating unwanted voltage spikes without affecting normal operation.

With a maximum clamping voltage of 9.2V, the SMF4L5.0A provides excellent overvoltage protection, effectively clamping the transient voltage to a safe level during voltage surges. This diode is rated for a non-repetitive peak power dissipation of 2000W, ensuring it can handle significant energy levels inherent during transient events. The silicon-based construction of the diode contributes to its reliability and performance in various electronic applications.

It is also worth noting that the SMF4L5.0A is RoHS compliant, which addresses concerns regarding hazardous substances in electronic components. The device is available in an SOD-123FL package, featuring a small outline design that enhances its compatibility with surface mount technology. The operational temperature range extends from -55°C to 150°C, offering flexibility for use in diverse environmental conditions.
