1500W bidirectional TVS — obsolete, but still spec'd into BOMs
The 1.5KE160CA_R2_00001: It protects a single line against both positive and negative transients, clamping at 219V maximum when the surge current hits 6.8A. The 136V reverse standoff voltage means this part sits on a nominal 120V rail and stays off until the transient exceeds 152V minimum breakdown. The bidirectional construction eliminates polarity concerns during assembly — a single orientation covers both surge directions.
Obsolete — sourcing through independent channels
Panjit has marked the 1.5KE160CA_R2_00001 as obsolete. No official successor is listed.
Clamping voltage and surge current — the protection envelope
The 219V clamp at 6.8A peak pulse current defines the voltage the downstream circuitry sees during a surge. For a 120VAC line, the 136V standoff gives margin above the nominal peak of ~170V, so the TVS stays in standby during normal operation. Operating temperature spans -65°C to 175°C, covering military and industrial environments. The 1500W rating is derated above 25°C per the standard power-temperature curve — at 175°C the peak pulse power drops to near zero, so the part must be sized for the ambient condition.
