The single bidirectional channel protects against both positive and negative transients on the same line. ## Clamping voltage and surge rating For a 214 V DC bus, this clamp leaves enough headroom for most downstream semiconductors rated at 400 V or higher. The 1500 W peak pulse rating is the product of clamp voltage and peak current at the specified waveform — derate this figure at elevated ambient temperatures per the manufacturer's curve. ## Obsolete — sourcing through surplus channels Vishay lists the 1.5KE250CA-/51 as obsolete. No official successor order code is recorded in the lifecycle data. Buyers should confirm lot traceability and date codes at RFQ. The TransZorb series includes many active 1.5 kW TVS variants in the same DO-201 package, but a pin-compatible replacement requires verifying the standoff voltage and bidirectional polarity match.","metaTitle":"1.5KE250CA-E3/51 Vishay TVS Diode, 1.5kW, 344V Clamp","metaDescription":"Vishay 1.5KE250CA-E3/51 TransZorb TVS, 1500W peak pulse, 214V standoff, 344V clamp, DO-201AA axial.
