BRCS3400MC 是 BLUE ROCKET 推出的一款 SOT-23 封装 N 沟道绝缘栅场效应管(MOSFET),面向便携式和板级功率管理应用。其额定漏源电压为 30V,连续漏极电流可达 5.8A,低导通电阻与小尺寸封装的组合使其在功率开关、负载开关与同步整流等场景具有良好性价比。
BRCS3400MC 在中等电压(30 V)等级内提供较低的 RDS(on),且在 2.5 V 驱动下即可实现较好的导通性能,适合与低压逻辑或 MCU 直接驱动。典型阈值电压约 1.45 V,意味着在 2.5 V 门极电压附近开始导通,但要达到低 RDS(on) 需要满足足够的 Vgs。输入电容(Ciss)约 1.03 nF,开关时需注意门极驱动能量与开关损耗;Crss 为 77 pF,会影响米勒效应与关断过渡过程。
BRCS3400MC 适合对尺寸与成本敏感、但需在 30 V 以内实现数安培开关的应用。与同类器件相比,其在低门极电压(2.5 V)下提供 40 mΩ 的 RDS(on),对 MCU 直驱型应用较友好;若需要更低导通损耗或更高功率处理能力,应考虑更大封装或更低 RDS(on) 的替代型号。
总结:BRCS3400MC 在 SOT-23 小封装中平衡了导通损耗、驱动电压与成本,是便携电源管理与中低功率开关场景的实用选择。设计时关注热管理与开关瞬态保护,可发挥其最佳性能。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
