Product Description
Taiwan Semiconductor SMBJ40A is a 1-element uni-directional transient voltage suppressor (TVS) diode built for high reliability in protecting sensitive electronic circuits from voltage spikes. This device features a peak pulse power dissipation capability of 600 W, enabling it to absorb high transient energy events effectively. Packaged in a compact 2-pin DO-214 surface mount format, it supports straightforward PCB assembly and space-saving installations.
The SMBJ40A offers excellent clamping voltage performance at 64.5 V and a minimum breakdown voltage of 44.4 V, with a maximum reverse stand-off voltage of 40 V. It can handle peak pulse currents up to 9.3 A, thus providing strong surge current handling capability in demanding environments.
With a wide operating temperature range from -55°C to 150°C and a low maximum reverse leakage current of only 5 microamperes, this diode is suitable for robust industrial and automotive systems where reliability is critical. Its single element glass-passivated junction design ensures fast response times and protects electronic circuits from Electrostatic Discharge (ESD) and other transient voltage events.
The small form factor with a length of 4.57 mm, width of 3.94 mm, and height of 2.237 mm makes this diode ideal for use in compact electronic assemblies requiring protection against surges and spikes.
This TVS diode complies with FBI standards and carries a UL94V-0 flammability classification for enhanced safety. It is an excellent choice for power supply lines, industrial controls, communication devices, and general electronic surge protection applications.
