1500 W bidirectional Zener TVS — clamping a 7.02 V rail
The 1.5KE8.2CA-B: It clamps transients on a 7.02 V reverse standoff rail to 12.1 V maximum, handling a peak pulse current of 125.6 A. The single bidirectional channel protects against both positive and negative surges in one package — useful for AC signal lines or DC buses where polarity reversal is possible.
Protection window and thermal envelope
Minimum breakdown voltage is 7.79 V, ensuring the device starts conducting before the protected circuitry sees damaging overvoltage. The 12.1 V clamping voltage limits the peak voltage across the load during a surge event. The DO-201AA (DO-27) axial-lead through-hole package fits existing PCB layouts and panel-mount surge protector designs. The bulk packaging suits low-to-medium volume assembly.
Sourcing and lifecycle posture
It remains suitable for both current production and new design-ins. No direct pin-compatible second-source is listed on the manufacturer's record.
