The Vishay Dale TPSMA39AHE3_B/I is a surface-mount Transient Voltage Suppressor (TVS) diode designed for high-reliability applications. It features a 400W peak pulse power capability with a 10/1000 μs waveform and a uni-directional polarity.
This TVS diode has a working voltage of 33.3V and a clamping voltage of 53.9V at a peak pulse current of 7.4A. It operates over a wide temperature range of -65°C to 185°C, making it suitable for automotive and high-temperature environments. The device meets MSL level 1 requirements.
Packaged in a DO-214AC (SMA) case, the TPSMA39AHE3_B/I is ideal for protecting sensitive electronics against voltage transients induced by inductive load switching and lightning. Its junction passivation optimized design ensures high temperature stability and reliability.
Key electrical characteristics include a peak forward surge current of 40A (8.3 ms single half sine-wave) and a maximum instantaneous forward voltage of 3.5V at 25A. The device is designed for surface mounting.
