PESD2CAN 是一款针对车载与工业差分总线(如 CAN)设计的双路瞬态电压抑制(TVS)二极管,封装为 SOT-23,品牌 DOWO(东沃)。器件为双向结构,专用于在差分信号线上对静电放电(ESD)、电快速瞬变(EFT)和雷击/浪涌脉冲提供可靠的瞬态抑制保护,能在有限空间内实现高效防护,适合车载、工业控制、楼宇自控等需要对总线侧抗干扰的场合。
PESD2CAN(DOWO,SOT-23 双路双向 TVS)在体积小、双通道、对称保护、对差分总线友好等方面具备明显优势。其 8 A 脉冲电流与约 420–450 W 的脉冲功率(8/20 μs)使其能有效缓解 ESD、EFT 和浪涌带来的瞬态风险,同时约 30 pF 的结电容在多数 CAN 与差分应用中对信号影响较小。正确的 PCB 布局与配套保护元件(如熔断器、阻尼器)能进一步提升系统可靠性,是车载与工业总线防护的实用元件选择。若需针对具体系统进行仿真或选型建议,可提供系统工作电压、预期冲击类型与 PCB 限制等参数以获得更精确的方案。

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.
