The clamping voltage at peak pulse current is 35.5V, which sets the upper limit the downstream circuitry must survive. The cathode band is clearly marked on the body, so orientation is straightforward under magnification. The 500W peak pulse power rating is specified with a 10/1000µs waveform — real-world pulse width and duty cycle affect derating, but for a 22V rail this part handles typical inductive-load or hot-plug spikes without issue. ## Peak pulse current and clamping voltage — the transient budget That current drives the clamping voltage to 35.5V, which is the voltage the protected IC sees during the transient. For a 22V rail, a 35.5V clamp gives about 13.5V of headroom above the rail — enough for most 30V-tolerant downstream parts, but check the absolute maximum rating of the load before committing.","metaTitle":"SMAJ22AE3/TR13 TVS Diode – 22V, 500W, DO-214AC","metaDescription":"SMAJ22AE3/TR13 Zener TVS diode, 22V reverse standoff, 500W peak pulse power, DO-214AC (SMA) surface mount.
