B772S 为一款小封装高增益 PNP 双极型晶体管,采用 SOT-23 封装,额定集电极电流 3A、集—射击穿电压 30V、耗散功率 1W。该器件在 Ic=1A、VCE=2V 条件下具有极高的直流电流增益(hFE≈400),同时具备 80MHz 的特征频率和较低的集电极漏电流,适用于便携电子、功率开关及信号放大等对体积与驱动能力有要求的场合。
封装为 SOT-23,体积小,适合集成 PCB。常见引脚排列(请以厂家原始资料为准):从标记面视角顺序 1、2、3 对应 B、E、C(不同封装脚位可能有差异,设计时务必核对数据手册)。SOT-23 的热阻较大,需通过 PCB 铜箔面积提升散热能力。
结语:B772S 以小体积、高增益和较高的电流能力,适合多种中低压、中大电流场合。最终设计与布局请参考 SHIKUES 官方完整数据手册与典型应用电路,以确保电气与热性能满足系统要求。

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.
