Obsolete 600 W bidirectional TVS — sourcing reality
The P6KE200CA-T is a 600 W bidirectional TVS diode from Diodes Incorporated, now listed as obsolete by the manufacturer. It clamps transients at 274 V (max) from a 171 V reverse standoff, with a breakdown voltage starting at 190 V. The DO-15 axial package is through-hole, which simplifies board rework or replacement in existing designs.
What the voltage ratings mean for circuit protection
At 190 V the breakdown region begins, and at 274 V the diode clamps the surge to a safe level — that 274 V is the maximum voltage the downstream components will see during a 10/1000 µs pulse. The bidirectional configuration means a single device protects both polarities — useful on AC signal lines or DC rails where reverse transients are possible.
Temperature grade and deployment context
The junction temperature range spans -55°C to +175°C, covering industrial and some automotive under-hood environments. The DO-15 axial body is a standard through-hole footprint — it mounts into a PCB or can be soldered directly to terminal points in a panel or power supply.
