SMBJ26CA 是 RUILON(瑞隆源) 出品的一款双向瞬态电压抑制器(TVS),封装为 DO-214AA(SMB)。该器件专为抑制瞬态过压、吸收浪涌能量设计,适用于对 ESD、EFT 等电磁瞬变有防护需求的电源与信号线路。器件符合 IEC 61000-4-2(静电放电)和 IEC 61000-4-4(电快速瞬变)等电磁兼容测试标准。
SMBJ26CA 的 Vrwm = 26 V 表明其适用于 24 V 及附近电压系统作为常态电压保护器件;当系统出现高能瞬态(如 10/1000μs 浪涌)时,器件能承受 600 W 的瞬态功率并限制电压在约 42.1 V,从而保护后级器件免受过压损坏。双向结构适合交流或无极性场合,对正负极均能提供对称保护。低漏电(1 μA)有利于低功耗应用和不影响精密测量。
如需替代或通用替换,关注关键参数匹配:Vrwm ≈ 26 V、Vbr ≈ 33 V、Vclamp ≤ 42 V(在相同 Ipp 条件下)、Ppp ≥ 600 W、双向结构及工作温度范围。选择时建议对比厂商器件的测试曲线与封装管脚兼容性。
SMBJ26CA 凭借 600 W 的瞬态吸收能力、较低的钳位电压和宽温度范围,适合对 24V 级电源与接口进行可靠的瞬态抑制。合理布局、恰当的热管理与按规范的焊接工艺可确保其在实际产品中发挥稳定保护作用。若需更详细的电气特性曲线或封装尺寸与回流焊建议,请参考 RUILON 提供的规格书。

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.
