The 2 pF junction capacitance at 0 V (1 MHz) keeps signal edges clean. ## Parametric deep-dive: leakage, forward drop, and capacitance Reverse leakage is 10 µA at 70 V — acceptable for most signal-level clamps, but if your circuit idles at elevated temperatures, remember that Schottky leakage doubles with every 10 °C rise. Forward voltage is 1 V max at 15 mA, typical for a small-signal Schottky. The 2 pF capacitance at zero bias means this diode can sit on a 10 MHz clock line without distorting the waveform. ## Lifecycle reality: obsolete, sourced to order STMicroelectronics lists the BAS70ZFILM as obsolete.","metaTitle":"BAS70ZFILM Schottky Diode, 70V 70mA SOD-123","metaDescription":"BAS70ZFILM Schottky diode: 70 V reverse, 70 mA forward, 2 pF capacitance, SOD-123.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Small Signal =< 200mA (Io), Any Speed","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Diode Type":"Schottky","Mounting Type":"Surface Mount","Package / Case":"SOD-123","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"BAS70","Capacitance @ Vr, F":"2pF @ 0V, 1MHz","Supplier Device Package":"SOD-123","Current - Reverse Leakage @ Vr":"10 µA @ 70 V","Voltage - DC Reverse (Vr) (Max)":"70 V","Current - Average Rectified (Io)":"70mA","Operating Temperature - Junction":"150°C(Max)","Voltage - Forward (Vf) (Max) @ If":"1 V @ 15 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f581b0738c7c110139d747675c05b4e5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BAS70ZFILM/alternatives.json"},"ai":{"faq":[{"question":"What is BAS70ZFILM's listed speed?","answer":"The speed classification is Small Signal =< 200 mA (Io), Any Speed — meaning it is rated for general-purpose small-signal switching, not ultra-fast recovery, but Schottky construction inherently gives fast turn-off."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/BAS70ZFILM","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/BAS70ZFILM when reusing this data.
