SMCJ300A/TR13 是 Brightking(台湾君耀)推出的一款单向瞬态电压抑制二极管(TVS),采用SMC(DO-214AB)表面贴装封装,专为电路板空间受限且需高能量浪涌保护的场合设计。该器件具有高反向截止电压(Vrwm=300V)、优异的钳位能力(Vc≈486V)与高峰值脉冲功率能力(Ppp=1.5kW),可对电源线和信号线上的大幅度瞬态过电压进行有效吸收与钳制,保护后级器件免受损害。
SMCJ300A/TR13 的工作温度覆盖 -55 ℃ 至 +150 ℃,适用于工业级工作环境;玻璃钝化与内应力消除设计提高了在潮湿、振动及温度循环等恶劣环境下的长期可靠性。典型漏电和击穿特性保证在长期服役中具有稳定的保护性能。
SMCJ300A/TR13 是一款面向中高压电源与接口保护的单向 TVS 器件,结合 SMC 小外形封装、低电感和高能量吸收能力,适用于需要高效瞬态抑制且对 PCB 布局空间敏感的工业和电源应用。选型时请参考完整的数据手册以确认具体测试条件及浪涌波形下的额定值,确保在目标应用场景中提供可靠保护。若需进一步的电气参数曲线、封装尺寸或参考布局文件,可向 Brightking(台湾君耀)或其授权代理获取详细资料。

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.
