The -50 °C low end matters for outdoor or cold-start environments; a TVS that conducts at cold temperatures can clamp a supply rail below its normal operating point and cause a brown-out if the clamping current pulls the rail down. The 150 °C ceiling is the usual IPC ceiling for a lead-free solder joint on a FR-4 board running near thermal limits. Unidirectional, single bidirectional channel — it protects one polarity of fault. If the board runs a split-rail or bipolar supply, you need a complementary TVS for the negative rail or a bidirectional part; this one does not float across a bipolar node.","metaTitle":"Diotec 1.5SMCJ26C TVS Diode, 1500W, 26V","metaDescription":"Diotec 1.5SMCJ26C unidirectional Zener TVS diode, 1500W peak pulse, 26V standoff, DO-214AB SMC.
