SMAJ6.8CA 是 TECH PUBLIC(台舟电子)推出的一款单路单向瞬态电压抑制二极管(TVS),封装为 DO-214AC(SMA)。该器件反向截止电压 Vrwm 为 6.8V,峰值脉冲功率 Ppp 为 400W(按 8/20μs 标准脉冲测试),工作温度范围宽(-55℃ 至 +150℃),适合对电源浪涌与瞬态过压有防护要求的电子系统使用。
SMA(DO-214AC)为表面贴装封装,体积小、热阻适中,便于在有限板面积上实现稳固的浪涌保护。推荐按照厂商给出的 PCB 封装与焊盘尺寸进行设计,确保可靠焊接与热散。
若应用于严格的汽车或安全关键领域,请向厂商确认是否通过 AEC‑Q101 等行业认证或要求相应的可靠性验证报告。常规工业与通信应用可凭借宽温和高能量指标获得可靠保护效果。
型号示例:SMAJ6.8CA;品牌:TECH PUBLIC(台舟电子);封装:DO-214AC(SMA);通道数:单路单向;主要参数:Vrwm=6.8V,Ppp=400W(8/20μs),工作温度 -55℃~+150℃。订购时请核对完整型号、出货卷带/散装要求及批次测试报告。
总结:SMAJ6.8CA 以其 6.8V 的反向截止电压、400W 的短时吸收能力和 SMA 标准封装,适合为 5V/6V 直流电源及相关电子系统提供高效、快速的瞬态过压保护。在具体设计中应注意 PCB 布局、热管理与配套限流措施,以确保最佳的防护效果与可靠性。

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.
