The DO-214AB SMC package footprint is shared across the SMCJ family — the same land pattern serves the 5 V through 170 V standoff variants, so a BOM change for a different rail voltage does not require a board spin. ## Active production — no last-time-buy pressure The -55°C to +150°C junction temperature range covers the full industrial temperature envelope — a base-station power supply or a motor-drive control board that sees 85°C ambient still has 65°C of margin before the die reaches its rated limit.","metaTitle":"SMCJ45CA-13 Diodes Inc TVS Diode, 1500W, 45V Bidirectional","metaDescription":"SMCJ45CA-13 bidirectional TVS diode, 1500W peak pulse power, 45V standoff, 72.7V clamp.
