The Littelfuse Inc. TPSMB440A-A is a TVS (Transient Voltage Suppressor) Diode designed to protect sensitive electronic equipment from voltage transients. It offers a peak pulse power dissipation of 600W at a 10/1000 µs waveform.
This device features a working voltage of 376V and a breakdown voltage of 602V, with a peak pulse current rating of 1A. It is suitable for automotive applications and provides ESD protection up to 30 kV (Air and Contact) in accordance with IEC 61000-4-2.
The TPSMB440A-A is a surface mount component housed in a DO-214AA (SMBJ) package. It has a fast response time, typically less than 1.0 ns, and operates within a junction temperature range of -65°C to 150°C. The diode is also RoHS3 compliant and halogen-free.
Key electrical characteristics include a maximum instantaneous forward voltage of 5V at 50A for unidirectional use. The thermal resistance from junction to lead is 20 °C/W, and junction to ambient is 100 °C/W.
