SMAJ14A/TR13 为 Brightking(台湾君耀)推出的一款单向 TVS 晶体管,采用 SMA 表面贴装封装,专为抑制瞬态过压和防护敏感电子元件而设计。器件在14V 工作电压下具有快速钳位能力,适用于汽车电子、工业电源与通信接口等需要抗浪涌保护的场景。
以上参数表明该器件在标准突发脉冲条件下能够将过压快速钳制到约23.2V,从而保护后端电路免受瞬态能量侵害。
SMA 封装为常用的 DO-214AC 表面贴装形式,体积小、散热路径短,便于自动贴装与回流焊接。SMAJ14A/TR13 对 PCB 布局要求较低,但为保证可靠性建议靠近被保护节点放置,并为焊盘提供足够的铜面积以利散热。
SMAJ14A/TR13 是一款针对中等能量瞬态保护优化的单向 TVS 器件,具有 14V 工作点、23.2V 钳位和 400W 峰值脉冲功率的特点,适合对成本、尺寸与性能有平衡需求的电源与接口保护方案。合理的 PCB 布局与热管理能显著提升其保护效果与寿命。

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.
