No official successor part number is published under the 1.5KE base series. For new designs or BOM maintenance, a parametric cross to another 1500 W, 10.2 V standoff Zener TVS in DO-201AD is the practical path. Confirming date-code consistency and original packaging is critical when sourcing from non-franchised supply. ## Package and mounting: DO-201AD axial leaded Through-hole DO-201AD axial package — the lead spacing and body diameter match industry-standard footprints for 1.5 kW TVS diodes. No special pad geometry beyond the usual 0.042-inch (1.07 mm) hole diameter for the leads. ## Sourcing the 1.5KE12AG today With the 1.5KE12AG classified Obsolete by onsemi, new-stock availability is limited to surplus inventories and distributor backlots. Pricing and lead time are lot-dependent — date-code spread and packaging condition (sealed reel vs. cut tape) drive the per-unit cost. Submit an RFQ with your target quantity and acceptable date-code window for a current-market assessment.","metaTitle":"1.5KE12AG onsemi Mosorb™ Zener TVS – 1500 W, DO-201AD","metaDescription":"onsemi 1.5KE12AG Zener TVS diode, 1500 W peak pulse power, 10.2 V standoff, DO-201AD axial.
