Obsolete TransZorb — last-time-buy sourcing
The 1.5KE160CHE3/54 is listed as Obsolete by Vishay. The part belongs to the Automotive, AEC-Q101 qualified TransZorb series — the AEC-Q101 certification covers the temperature and reliability stress profile for automotive-grade discrete semiconductors, including the -55°C to +175°C operating junction range.
The bidirectional channel clamps transients to 230 V maximum at 6.5 A peak pulse current — this sets the voltage stress the downstream circuitry sees during a surge event. The reverse standoff voltage is 130 V, meaning the diode does not conduct at normal 130 V DC bus levels; it starts avalanche breakdown at 144 V minimum. Through-hole DO-201AA axial package — the leaded form factor suits high-reliability point-to-point wiring or socketed boards where a surface-mount TVS would be mechanically weaker under vibration.
