It delivers 600W peak pulse power per the 10/1000µs waveform, with a clamping voltage of 69.4V at the peak pulse current of 8.6A. The bidirectional channel means it protects both positive and negative transients relative to ground, which matters for AC signal lines or DC rails where polarity reversal is possible. The SMBJ (DO-214AA) package is a surface-mount footprint larger than the SMA sibling, allowing higher pulse energy dissipation — a practical consideration when the PCB copper area is limited.
Temperature range and operating margin
Rated for continuous junction temperature from -65°C to 150°C, this TVS suits equipment exposed to outdoor temperature swings or elevated internal ambient, such as telecom cabinets or industrial control enclosures.
