Littelfuse, Inc. Tvs Smf4L 45V Uni, 7 Tr / Tr Rohs Compliant Littelfuse SMF4L45A

The Tvs Smf4L 45V Uni, 7 Tr / Tr is a uni-directional transient voltage suppressor (TVS) diode designed to protect sensitive electronic equipment from voltage transients caused by lightning and other transient events. It features a low-profile SOD-123FL package, making it suitable for surface mount applications where board space is a concern. This device has a peak pulse power dissipation capability of 400W at a 10/1000¬µs waveform and 2000W at an 8/20¬µs waveform. The operating and storage temperature range is from -55¬8C to 150¬8C. The breakdown voltage is specified at 50V, with a maximum reverse leakage current of 5.5¬µA at the reverse stand-off voltage. The device also offers excellent clamping capability and fast response times, typically less than 1.0ns. The SMF4L series is compliant with RoHS standards and features a glass passivated junction for enhanced reliability. It is suitable for applications including portable devices, power supplies, and data line protection. The product is packaged in tape and reel format for easy handling and assembly.
