600W Zener TVS — the clamping profile for a 24V rail
The P6KE27A-T: Its 23.1V reverse standoff voltage sits just above a nominal 24V DC rail, so it conducts only when the line exceeds that threshold — the clamping voltage peaks at 37.5V at the rated 16A peak pulse current, which keeps downstream components inside a typical 40V absolute-maximum rating for 24V bus transients. The breakdown voltage range starts at a minimum of 25.7V, meaning the device begins to avalanche before the rail reaches 26V — tight enough to protect a 24V sensor or PLC input module from inductive kickback or surge coupling without nuisance clipping on normal ripple.
DO-15 axial — through-hole for high-reliability and rework
Housed in the DO-204AC (DO-15) axial leaded package, the P6KE27A-T is a through-hole part — the leads are soldered into plated through-holes on the PCB, which gives a stronger mechanical anchor than a surface-mount TVS in high-vibration or high-thermal-cycling environments. The junction temperature range spans -55°C to 175°C, covering most industrial and automotive under-hood profiles without derating at the upper end.
Obsolete — sourced from surplus and factory excess lots
Diodes Incorporated lists the P6KE27A-T as obsolete. Available through independent distribution from surplus and factory excess inventory — each lot is date-code and condition verified before offer.
