SMBJ58CA是瑞隆源(RUILON)推出的一款小型化表面贴装双向TVS管,专为电子电路中的瞬态过压防护设计,凭借紧凑的SMB封装、宽温度范围耐受及稳定的浪涌防护能力,广泛适配消费电子、工业控制等多领域的高密度PCB布局需求。
SMBJ58CA属于瞬态抑制二极管(TVS) 范畴,核心功能是快速响应电路中的浪涌脉冲(如静电放电、雷击感应、开关瞬态等),将过电压钳位在安全范围内,避免后级敏感器件(如IC、传感器、接口电路)被击穿损坏。其双向极性设计无需区分正负极,简化了电路设计与焊接工艺,适配各类双向信号链路的防护场景。
SMBJ58CA的电气参数经过严格测试,核心指标直接决定其防护能力与适用场景:
反向漏电流(Ir=1μA):在Vrwm=58V下的漏电流仅1μA,远低于多数同类器件,长期工作时几乎不产生额外功耗,避免影响电路效率与稳定性。
SMBJ58CA采用SMB封装(DO-214AA标准),具备以下优势:
SMBJ58CA的参数特性使其适配多类场景:
核心应用优势:
SMBJ58CA的可靠性指标满足行业标准:
SMBJ58CA由国内知名过压保护器件厂商瑞隆源(RUILON) 生产,产品符合:
总结:SMBJ58CA作为一款高性价比的双向TVS管,以紧凑封装、稳定防护、宽温耐受为核心优势,是消费电子、工业控制等领域电路过压防护的可靠选择。
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.
