5.0SMDJ16CA 是 DOWO(东沃)出品的一款双向瞬态电压抑制(TVS)二极管,封装为 SMC(DO‑214AB)。该器件专为高能量瞬态脉冲保护设计,能够在瞬时过电压或雷击/开关浪涌事件中快速钳位,保护下游敏感电子元件。它适用于汽车、工业控制、电源接口、通信和其他需要高能量冲击保护的场景。
这些参数表明该器件在 10/1000 µs 波形下能够吸收大能量冲击并将电压钳制在 26 V 左右,适合处理高能量的脉冲事件(例如雷击后的后续脉冲或工业开关产生的浪涌)。
5.0SMDJ16CA 使用 SMC(DO‑214AB)表面贴装封装,体积适中,便于自动贴片与回流焊工艺。SMC 封装具有较大的铜焊盘面积和导热路径,有利于在脉冲事件中将热量传导到 PCB,降低器件结温上升速度。设计 PCB 时应考虑宽敞的焊盘和热扩散铜层以增强散热能力,必要时可增加底层散热过孔或铜箔面积。
总结:5.0SMDJ16CA(DOWO)是一款面向高能量瞬态保护的双向 TVS 二极管,凭借 5 kW 的 10/1000 µs 吸收能力、较低的钳位电压(26 V)和宽温度适应范围,适合汽车与工业等严苛环境中的浪涌防护。选择与布局时应综合考虑工作电压、钳位裕度、能量分配与热管理,以确保长期稳定保护效果。

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.
