SPD9103W-2/TR 是 WILLSEMI(韦尔)推出的小封装双向 TVS 静电与浪涌保护器件,封装为 SOD-323,适用于对 3.3V 电源或信号线的瞬态过压防护。器件响应快、漏电流低、结电容小,专为接口、通信和低电压数字电路的 ESD/EFT/Surge 防护设计。
SPD9103W-2/TR 能在纳秒级响应瞬态脉冲,钳位性能在高能量浪涌下仍能保持有效电压限幅,保护下游器件不被超过绝对最大额定值。100 pA 的极低静态漏电结合约 1 pF 的结电容,使其在低功耗与高速信号通路(如 I2C、SPI、UART、串行接口及精密模拟输入)中表现良好。SOD-323 封装利于小面积布局和自动贴装。
SPD9103W-2/TR 以其小封装、低漏电、低电容及良好的钳位和浪涌承受能力,是 3.3V 系统和高速信号线可靠的瞬态保护选择。

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.
