SMBJ400CA/TR13是台湾君耀(Brightking)推出的双向瞬态抑制二极管(TVS),专为电子设备的过压瞬态防护设计,核心作用是在电路遭遇雷击浪涌、静电放电(ESD)、开关瞬态等异常过压时,快速导通并钳位电压至安全范围,保护后端敏感元器件(如MCU、传感器、通信芯片等)免受损坏。
该器件的参数适配场景包括:
SMBJ400CA/TR13的核心参数需结合TVS防护逻辑理解,关键指标如下:
SMBJ400CA/TR13采用SMB封装(DO-214AA),是表面贴装型封装,具备以下特点:
将TVS并联于电源正极(Vcc)与地(GND)之间:
针对RS485、CAN等差分接口,可将TVS跨接于差分线(A/B)与地之间,或跨接于差分线之间(双向防护),避免通信芯片因静电/浪涌损坏。
君耀SMBJ400CA/TR13符合多项可靠性标准:
该器件凭借双向防护、紧凑封装及高可靠性,成为中高压电路瞬态防护的优选方案。

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.
