SMAJ58CA 是一款双向瞬态电压抑制(TVS)二极管,采用 SMA(DO‑214AC)封装,由 DOWO(东沃)生产,专为对抗工业和电子设备中出现的瞬态过电压事件而设计。产品在 10/1000 μs 脉冲波形下可承受高达 400W 的峰值脉冲功率,适用于电源线、通信接口、继电器驱动回路和各种需要双向浪涌保护的场合。
(注:上述钳位电压与峰值电流给出典型与最大值,以便在设计时进行裕量评估。)
若系统最大持续工作电压接近或略低于 58 V,且需要双向瞬态保护,SMAJ58CA 是经济且可靠的选择。对于更高能量或更频繁的冲击场合,可考虑并联相同型号或选用更高功率等级的 TVS。关键工程参数应在样机验证阶段通过实测钳位电压、漏电流和热稳定性来最终确认。
如需进一步的封装尺寸图、曲线特性(I‑V、钳位随温度变化曲线)或可靠性测试报告,可提供具体需求以便获取详细资料。

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.
