Breakdown occurs between 42.3 V (minimum) and the clamping ceiling — this window protects downstream silicon rated for 50–60 V without nuisance triggering on normal rail ripple. ## Through-hole fit and temperature range Unidirectional (single-channel) polarity — cathode band marks the anode for DC line protection. The part is not rated for power line protection (no bidirectional option), so it is intended for signal or DC bus transient suppression.","metaTitle":"Vishay 1.5KE47-E3/73 TransZorb TVS, 1500W, 38.1V Standoff","metaDescription":"Vishay 1.5KE47-E3/73 TransZorb TVS diode, 1500W peak pulse, 38.1V standoff, DO-201AA axial.
