The 42 A peak pulse current (10/1000 µs) at the 37.5 V clamp level defines the surge capacity — useful for sizing the TVS against expected transient energy in industrial or automotive 24 V bus applications. ## DO-201 axial package — through-hole board fit Housed in the DO-201AA (DO-27) axial-lead package, the diode mounts through-hole and requires a 0.052-inch diameter lead hole on the PCB. The axial form factor is standard for high-power transient suppressors — the leads carry the 42 A surge without trace heating at the board interface.","metaTitle":"1.5KE27CA A0G TVS Diode, 1500W, 37.5V Clamp, DO-201","metaDescription":"1.5KE27CA A0G TVS diode from Taiwan Semiconductor, 1500W peak pulse power, 37.5V clamping, bidirectional, DO-201 axial.
