SP1103C-01UTG 是 Littelfuse(美国力特)推出的一款双向瞬态抑制二极管(TVS),专为汽车级和工业级瞬态浪涌与静电放电(ESD)保护设计。器件满足 AEC‑Q101 汽车质量规范,并通过 IEC 61000‑4‑2(静电放电)、IEC 61000‑4‑4(电快速瞬变)和 IEC 61000‑4‑5(浪涌)等抗扰度等级,适用于车载电源线、传感器接口、通用低压电路的浪涌/ESD 防护场景。
以上参数反映了器件在8/20 μs浪涌脉冲测试条件下的瞬态承受能力与稳态特性,符合工业与车规应用对瞬态抑制的需求。
SP1103C-01UTG 是一款面向汽车与工业级应用的双向 TVS 抑制器,具备高达 720 W(8/20 μs)能量承受能力和 80 A 峰值冲击电流能力,封装紧凑且符合 AEC‑Q101。适用于对 3.3 V 电源与低速接口的浪涌与 ESD 保护,但在高速数据线应用中需慎重考虑其 130 pF 的结电容影响。合理的 PCB 布局与接地设计能够最大化其防护效率,确保系统在复杂电磁环境下的可靠性。

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.
