1.5kW bidirectional TVS — Vishay TransZorb 1.5KE36CA/54
The single bidirectional channel protects against both positive and negative transients on the same line, simplifying board layout for AC or bipolar DC rails.
Obsolete — sourcing through independent channels
No official successor is listed on the record.
Package and thermal envelope
Housed in a DO-201AA (DO-27) axial-lead package, it mounts through hole — the leads carry the transient current into the PCB copper pour, which acts as the primary heatsink. The junction temperature range spans -55°C to 175°C, covering industrial and military-grade thermal environments.
