Breakdown starts at 86.5 V minimum, and the clamping voltage is 125 V maximum at the 12.2 A peak pulse current. For a 72 V or 80 V DC bus, the 77.8 V standoff gives margin; the 125 V clamp protects downstream semiconductors rated for 150 V or higher. ## DO-201 axial — through-hole, hand-solder or wave The DO-201AA / DO-27 axial-lead package (supplier device package DO-201) is a standard through-hole form factor for high-power transient suppressors. It mounts into 1.0 mm to 1.3 mm diameter plated-through holes on a 0.5\" lead spacing. The junction temperature range is -55°C to +150°C, covering engine-bay, industrial cabinet, and outdoor enclosure thermal profiles.","metaTitle":"YAGEO 1.5KE91A/B Zener TVS, 1500 W, DO-201","metaDescription":"YAGEO 1.5KE91A/B Zener TVS diode, 1500 W peak pulse power, 77.8 V standoff, DO-201AA axial package.
