| Working Peak Reverse Voltage |
The 1SMA40AT3G is a unidirectional TVS (transient voltage suppression) diode from Littelfuse Inc., designed to protect sensitive electronic circuits from high voltage transients. It features a working peak reverse voltage of 40V and a clamping voltage of 64.5V, with a peak pulse power dissipation of 400W (1ms pulse). The device can handle a peak pulse current of 6.2A and has a capacitance of 315pF at 1MHz.
This TVS diode is housed in a surface-mount DO-214AC (SMA) package, suitable for automated assembly. It operates over a wide temperature range of -65°C to 150°C. The part is intended for general-purpose applications and does not include power line protection.
Design engineers should note that the datasheet provided for this part number is incorrect (references the 1SMA10CAT3G series). Key electrical parameters such as breakdown voltage, reverse leakage current, and test current are not available from the current data sources. Verification of specifications from the manufacturer is recommended.
