The 10/1000µs pulse condition is the industry-standard waveform for TVS rating — a 34A peak current at that pulse width means the device absorbs roughly 1500W for one millisecond without failing short. For shorter transients (like 8/20µs ESD pulses), the device handles significantly higher peak currents. ## Package and board integration for through-hole designs Housed in a DO-201AA / DO-27 axial leaded package (supplier device package DO-201), the 1.5KE33CA A0G mounts through-hole. The axial leads suit point-to-point wiring or PCB mounting with standard 0.100-inch pitch hole spacing. The junction operates from -55°C to 175°C, covering industrial enclosure ambient and moderate self-heating from repetitive surges. ## Bidirectional channel — one device protects both polarities A single bidirectional channel means the diode clamps positive and negative transients symmetrically. On a 24V DC rail, a positive-going surge above 45.7V and a negative-going surge below -45.7V both get clamped to the same absolute voltage.","metaTitle":"1.5KE33CA A0G TVS Diode, 1500W, 28.2V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE33CA A0G bidirectional TVS, 1500W peak pulse, 28.2V standoff, 45.7V clamp.
