AEC-Q101 qualification confirms the device meets automotive-grade reliability screening — temperature cycling, high-temperature reverse bias, and ESD robustness — so it suits under-hood or chassis-mounted modules where the ambient temperature range spans -55°C to 175°C. ## Clamping voltage and current handling Breakdown occurs at 28.5V minimum, clamping the line to 41.4V maximum at the rated 38A peak pulse current. This clamping ceiling keeps downstream 40V-rated silicon (MOSFETs, linear regulators) inside their safe operating area during a transient event. The bidirectional configuration means the part clamps symmetrically on both polarities — useful for AC-coupled signal lines or power rails where reverse-voltage events are as likely as overvoltage. ## Package and handling for the storeroom Supplied in DO-201AA (DO-27) axial-lead package, tape-and-reel format. The through-hole body is straightforward to hand-solder or wave-solder; no moisture sensitivity level (MSL) concern for long shelf storage.","metaTitle":"1.5KE30CAH TVS Diode, 1500W, 25.6V, DO-201, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE30CAH bidirectional Zener TVS, 1500W peak pulse, 25.6V standoff, DO-201 axial, AEC-Q101 automotive grade.
