Typical on-resistance is 31 mOhm, which keeps conduction losses low in battery-powered and point-of-load distribution — at 1 A the I²R loss is under 31 mW, negligible for most portable designs. Integrated fault protection includes fixed current limiting, over-temperature shutdown, and reverse-current blocking — the reverse-current protection prevents back-feed from the load side when the switch is off, a common requirement in multi-rail power sequencing. ## Control interface and load-discharge feature The switch is controlled by a single non-inverting On/Off logic input — a GPIO from a microcontroller or system controller directly enables the output rail without an external level shifter. A built-in load-discharge feature actively pulls the output to ground when the switch is turned off, preventing floating output rails that could cause erratic behaviour in downstream logic or hold-up in capacitive loads. ## Package and board integration — 6-WCSPE Supplied in a 6-UFBGA, WLCSP package (Toshiba designation WCSPE) with a body size of 0.80 mm x 1.2 mm — the 0.4 mm pitch ball grid array demands a controlled reflow profile and careful solder-paste stencil design to avoid bridging. Surface-mount assembly; the small footprint suits space-constrained PCBs in wearables, IoT modules, and handheld instruments.","metaTitle":"TCK1024G,LF Toshiba P-Channel Load Switch, 1.54 A, 31 mOhm","metaDescription":"Toshiba TCK1024G,LF P-channel high-side load switch, 1.54 A max, 31 mOhm typ Rds(on), 1.4-5.5 V, WCSPE package, active production, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Load Discharge","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"P-Channel","Switch Type":"General Purpose","Rds On (Typ)":"31mOhm","Mounting Type":"Surface Mount","Package / Case":"6-UFBGA, WLCSP","Voltage - Load":"1.4V ~ 5.5V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature, Reverse Current","Number of Outputs":"1","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 85°C (TA)","Current - Output (Max)":"1.54A","Supplier Device Package":"6-WCSPE (0.80x1.2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.54","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.54000","currency":"USD"},{"qty":10,"price":"$0.45700","currency":"USD"},{"qty":100,"price":"$0.31770","currency":"USD"},{"qty":500,"price":"$0.24808","currency":"USD"},{"qty":1000,"price":"$0.20165","currency":"USD"},{"qty":2000,"price":"$0.18026","currency":"USD"},{"qty":5000,"price":"$0.17109","currency":"USD"},{"qty":10000,"price":"$0.15887","currency":"USD"},{"qty":25000,"price":"$0.15521","currency":"USD"},{"qty":50000,"price":"$0.15125","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4c7aa707c9236dc09c52069ebbf333cf.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/toshiba/TCK1024GLF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/toshiba/TCK1024GLF when reusing this data.
