The typical recommended land pattern follows IPC-7521; the exposed metal pad on the bottom must be well-soldered across its full width, as it is the primary heat path from junction to board. No official successor or cross-reference appears in the ledger, so sourcing relies on the Diotec family channel and spot-market availability through independent distribution.","metaTitle":"Diotec 1.5SMCJ85C TVS Diode, 1500W Peak, 85V Standoff, SMC","metaDescription":"Diotec 1.5SMCJ85C unidirectional TVS diode, 1500W peak pulse, 85V standoff, 151V clamping, DO-214AB SMC surface-mount.
