The SMBJ170A is a 600W transient voltage suppression (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. It is part of the SMBJ series from Littelfuse and offers a reverse standoff voltage of 170V and a clamping voltage of 275V at a peak pulse current of 2.2A (10/1000μs waveform). The device is unidirectional with a single channel and is intended for general-purpose protection applications.
Key electrical characteristics include a peak pulse power dissipation of 600W under a 10/1000μs test waveform, a typical leakage current of less than 1μA for breakdown voltages above 12V, and fast response time typically less than 1.0ps from 0V to minimum breakdown voltage. The operating junction temperature range is -65°C to 150°C.
The SMBJ170A is housed in a surface-mount DO-214AA (SMB) package, making it suitable for automated assembly and space-constrained designs. The package features matte tin lead-free plating and meets MSL level 1 per J-STD-020. The device is halogen free, RoHS compliant, and has UL recognition for flammability classification V-0.
The reverse standoff voltage (Vrwm) is 170 V.
The clamping voltage is 275 V at the rated peak pulse current of 2.2 A.
The peak pulse current is 2.2 A for a 10/1000 μs waveform.
The device comes in a surface-mount DO-214AA (SMB) package.
The peak pulse power is 600 W for a 10/1000 μs waveform.
The operating junction temperature range is -65°C to 150°C.
It is a unidirectional TVS diode with one channel.
