Transient protection for 53 V rails
The P6KE62CA-T: This clamping voltage is the survival limit for the downstream circuitry — anything rated below 85 V on that rail sees the full transient energy.
Bidirectional — one device for AC or bipolar lines
A single bidirectional channel means the P6KE62CA-T protects both polarities in one DO-15 package. For a 53 V AC signal pair or a ±53 V DC rail, one part covers both directions without needing back-to-back series diodes — saving board space and reducing insertion loss compared to a unipolar pair. At 175°C the leakage current rises, but the clamping action remains within the 85 V ceiling.
Obsolete — sourcing through independent channels
Diodes Incorporated lists the P6KE62CA-T as obsolete. Tape and reel packaging supports automated insertion for volume builds if the reel quantity matches the line requirement.
