Surge protection for 136 V rails
The 1.5KE160CAHE3_A/C: It clamps transients at 219 V maximum while holding off a 136 V DC line under normal conditions — sized for 48 V battery systems, 120 VAC rectified rails, or any bus that sees a nominal 136 V or below. The DO-201AA axial-lead package suits through-hole mounting in power distribution modules, junction boxes, or engine-control units.
Clamping performance and pulse current
With a breakdown voltage of 152 V minimum and a clamping voltage of 219 V at 6.8 A peak pulse current, this device triggers above 152 V and holds the line below 219 V during a surge. The 6.8 A rating (10/1000 µs) is the current the diode can sink at the clamp voltage — useful for estimating margin against a given transient energy. Bidirectional construction means a single device protects both polarities on AC lines or DC buses subject to reverse-battery events. No power-line protection feature is built in — this is a discrete transient suppressor, not a filtered or coordinated protector.
