SMAJ28A是一种专业设计的瞬态电压抑制器(TVS),广泛应用于静电放电(ESD)和浪涌保护的场合。这种二极管的核心功能是保护电路免受瞬态过电压的损害,同时提供可靠的性能和极高的耐用性。其最大击穿电压为34.4V,反向工作电压Vrwm为28V,反向漏电流仅为1μA,大大降低了对电路的影响。SMAJ28A采用DO-214AC封装,方便集成到各种电子设备中。
SMAJ28A的主要技术参数如下:
这些参数共同定义了SMAJ28A在极端条件下的性能,确保其在各种应用下的可靠性和有效性。
SMAJ28A TVS二极管通过在瞬态过电压事件发生时迅速导通,从而把多余的电压引导至地线。与普通二极管不同的是,TVS二极管能够在极短的时间内响应电压突变,其反应时间通常在皮秒级别,有效地保护下游器件。
一旦电压超过其击穿电压,TVS 二极管便会被驱动进入导通状态,形成一个低阻抗的通路,将过量电压有效钳制在最大钳位电压(45.4V)下,从而保障电路中的敏感组件不会受到损害。
SMAJ28A广泛应用于各种产品及领域,包括:
高效保护:SMAJ28A的极低漏电流确保在正常工作条件下几乎不影响电路性能,从而提升系统的整体效率。
宽工作温度范围:其工作温度范围从-65℃到+150℃,使得SMAJ28A能够在各种恶劣环境中稳定工作,适用于工业和汽车等应用场合。
高脉冲承载能力:该元件能够承受高达400W的峰值脉冲功率和8.8A的峰值脉冲电流,使其在面对较为严峻的瞬态事件时依旧可靠。
小体积与简易集成:DO-214AC封装为设计师提供了便捷的安装方式,允许其在空间有限的情况下,还能实现有效保护。
总之,SMAJ28A作为一款高性能的TVS二极管,以其优异的电气特性和广泛的应用范围,将在现代电子设备中发挥极其重要的保护作用。无论是在家庭、工业还是汽车领域,SMAJ28A都能高效地为电路提供瞬态电压保护,是保证设备安全可靠运行的重要组成部分。通过采用SMAJ28A,设计师能够大幅提高其产品的抗干扰性能和稳定性。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
