The TPSMF4L10A is a 400W surface mount Zener TVS diode from Littelfuse, designed to protect sensitive electronic equipment from voltage transients. It features a clamping voltage of 17V and a peak pulse current of 23.5A under a 10/1000µs waveform. The device is AEC-Q101 qualified for automotive applications and meets IEC 61000-4-2 ESD protection standards with 30kV air and contact discharge capability.
Key electrical characteristics include a fast response time of less than 1.0ns from 0V to VBR min, and a wide operating temperature range from -55°C to 150°C. The diode is unidirectional with one channel, making it ideal for DC line protection. It is lead-free, halogen-free, and RoHS3 compliant, with MSL Level 1 for unlimited moisture sensitivity.
The component is housed in a low-profile SOD-123FL package with matte tin termination finish, suitable for surface mount assembly. Thermal resistance is 220°C/W junction-to-ambient and 100°C/W junction-to-lead, ensuring efficient heat dissipation in compact designs.
