Reverse leakage is specified at 4 µA at 200 V, a figure that rises with junction temperature. The maximum junction temperature is 175°C, which gives headroom for high-ambient designs if the thermal pad is properly managed. STMicroelectronics lists the STTH802CB as obsolete.","metaTitle":"STTH802CB dual common-cathode fast recovery diode, 20 ns trr","metaDescription":"STMicroelectronics STTH802CB dual common-cathode fast recovery diode in DPAK. 200 V, 4 A per diode, 20 ns trr.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tube","Diode Type":"Standard","Mounting Type":"Surface Mount","Package / Case":"TO-252-3, DPak (2 Leads + Tab), SC-63","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH802","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"DPAK","Reverse Recovery Time (trr)":"20 ns","Current - Reverse Leakage @ Vr":"4 µA @ 200 V","Voltage - DC Reverse (Vr) (Max)":"200 V","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"1.1 V @ 4 A","Current - Average Rectified (Io) (per Diode)":"4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9fe8d7df2f9f19b21bb94b02425ea2ef.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH802CB/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STTH802CB?","answer":"No official replacement part number is recorded for the STTH802CB.
