The TPSMF4L series TVS diode, specifically part number 31AC7144, is designed for transient voltage protection in sensitive electronic applications, particularly in automotive environments. It features a unidirectional configuration and is AEC-Q101 qualified, ensuring high reliability. The device can handle 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 various transient events, including those caused by lightning. With a reverse stand-off voltage of 48V, the diode has a maximum clamping voltage of 77.4V and a breakdown voltage range that is compliant with RoHS standards. The operating temperature range is from -55¬8C to 150¬8C, allowing for versatility in different environments. The SOD-123FL package is optimized for surface mounting, which helps save board space. This diode is particularly effective for protecting data lines and other sensitive components in consumer electronics and automotive applications.
The TPSMF4L series of SOD-123FL small and flat lead low-profile plastic package is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events, and it’s especially suitable for high reliability and automotive application High-reliability and automotive-grade AEC-Q101–qualified 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
