1.5KE43CA 为 DOWO(东沃)出品的双向瞬态抑制二极管(TVS),采用玻璃钝化芯片,封装为 DO-201AD。器件面向高能量瞬态浪涌保护,峰值脉冲功率能力 1500W(波形 10/1000μs,重复率/占空比 0.01%),适用于对电源线或信号线的强烈脉冲干扰防护。
适用于工业电源、通信线路、车载电子(非直接替代高压车规器件需核查)、逆变器控制回路、变频器输入/控制端、测试设备、接口保护(如串口、I/O 口)等需要承受高能量瞬态脉冲的场合。
DO-201AD 为轴向/大体积封装,便于通过孔安装,具有较好散热路径。推荐布板和安装注意:
玻璃钝化工艺提高了器件的长期稳定性与抗环境能力,工作温度范围宽(-55°C~+150°C),适合工业级应用。产品符合 RoHS 要求,实际应用中仍建议进行抗冲击/振动和温度循环测试以验证系统可靠性。
在选用 1.5KE43CA 时,确认系统允许的最大钳位电压与 Vrwm 匹配;若线路电压较低,可考虑 Vrwm 更小型号以获得更低钳位电压;若需更高脉冲能量或更低钳位电压,可并联/级联或选择更高功率等级的 TVS,同时注意并联时电流分配与热管理。若需单向保护,可选择对应的 1.5KE43CA 单向版本。
如需器件封装图、详细电气表格或样片信息,可提供进一步资料以便精准选型与布局建议。

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.
