Obsolete — what this means for your BOM
That means the manufacturer has ended production and no further last-time-buy windows are open. For a production BOM, this part must be sourced through independent distribution — stock is fixed and finite. Every lot we quote is date-code verified and tested for authenticity before shipment; we do not ship mystery stock that surfaced years after the official last-time-buy closed.
Key ratings — what drives the fit
The minimum breakdown voltage is 28.5 V, and the clamping voltage at peak pulse current is 53.5 V max — so downstream components must survive that clamp ceiling. Peak pulse power is 1500 W, and the peak pulse current is rated at 187 A under the 8/20 µs waveform. That 187 A figure is the surge it can handle once; repetitive pulsing needs derating per the thermal curve, which the datasheet covers. Capacitance sits at 1450 pF at 1 MHz — fine for DC power rails and low-speed lines, but too high for high-speed data interfaces like USB 2.0 or Ethernet without signal degradation.
Package and mounting — through-hole axial
The 1.5KE30CARL comes in a DO-201AA / DO-27 axial-lead package, through-hole mount. The DO-201 footprint is standard for this power class — lead spacing and body diameter match the common 1.5KE family layout. No MSL concern for through-hole parts; just standard ESD handling during insertion. The axial leads suit point-to-point wiring on terminal blocks or PCB through-hole layouts, but the body is larger than an SMC or SMA surface-mount TVS, so board space is the trade-off.
