No official successor is listed on the record, so replacement must be evaluated on a form-fit-function basis for the specific application. For BOM lines still calling out this exact MPN, independent distribution is the primary channel.
The breakdown voltage minimum is 4V, so the device remains non-conductive below that threshold. Peak pulse power is rated at 120W under an 8/20µs waveform, with a corresponding peak pulse current of 11A. The clamping voltage at that current is 10.9V max, which means a 2.5V signal line sees a transient clamped to under 11V – sufficient for many consumer-grade ICs but check the absolute maximum rating of the protected device.
Capacitance and package – layout constraints
Capacitance is 145pF at 1 MHz. This is a moderate value – fine for low-speed control signals or I2C, but too high for high-speed differential pairs like USB 2.0 (480 Mbps) or Ethernet, where loading above 5pF per line degrades signal integrity. The SOD-523 package (SC-79 equivalent) measures roughly 1.6 x 0.8 mm with a 0.6 mm height. It is a surface-mount footprint suited for automated assembly; manual rework is possible with a fine-tip iron and magnification. The small body limits thermal dissipation, so the 120W rating assumes a short-duration pulse, not continuous power.
