Transient suppression for 150 V rails
The SMCJ150CA-13: With a 150 V reverse standoff voltage, it stays transparent under normal line conditions and begins conducting at a minimum breakdown of 167 V, clamping the peak surge to 243 V at the rated 6.2 A peak pulse current (10/1000 µs waveform).
1.5 kW pulse handling in a surface-mount package
The bidirectional configuration (single channel) protects signal or power lines that swing both positive and negative relative to ground — common on AC-coupled data lines or bipolar supplies. The DO-214AB (SMC) package provides a low-inductance surface-mount footprint compatible with reflow soldering.
