SMCJ26A 是一种单向(极性:单向)瞬态电压抑制(TVS)二极管,封装为 SMC(DO-214AB),由 BORN(伯恩半导体)提供。该器件用于抑制瞬态过电压事件,如雷击、电气快速脉冲或感性负载开关引起的浪涌,保护下游电子设备免受过电压损坏。其主要电气参数包括反向额定工作电压 Vrwm = 26V、典型钳位电压 Vcl = 42.1V(在标准脉冲条件下)、峰值脉冲电流 Ipp = 35.6A(10/1000μs 波形),峰值脉冲功率 Ppp = 1.5kW(10/1000μs),击穿电压 Vbr ≈ 31.9V,静态反向漏电流 Ir ≈ 1μA。
注:10/1000μs 表示浪涌电流波形的上升时间为 10μs,下降到峰值的 50% 所需时间为 1000μs,是常用的工业浪涌试验波形。
总结:SMCJ26A(BORN)是一款面向 24V 级别系统的单向 TVS 器件,具备良好的瞬态能量吸收能力和较低漏电流,适用于工业电源与信号线的过压保护。在实际应用中应注意极性连接、PCB 布局与热管理,并根据系统浪涌能量选择合适的器件或配合其他保护元件使用。若需更详细的电压-电流特性曲线、温度特性或封装机械尺寸,请参考厂商数据手册。

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.
