S-SMAJ30CA是乐山无线电(LRC)推出的双向瞬态抑制二极管(TVS),属于电路过压防护领域的核心器件。其核心作用是在电路遭遇瞬态浪涌(如静电放电、感应雷击、开关浪涌等)时,快速从截止状态切换为导通状态,将电压钳位至安全范围,避免后级敏感元件(如MCU、传感器、接口芯片)被击穿损坏。
双向设计是该器件的核心优势:无需区分正负极性,可同时抑制正、负方向的瞬态脉冲,简化电路设计与布线,尤其适合对极性无明确要求的防护场景(如USB接口、双向通信端口)。
该器件的参数经过中低压场景优化,核心参数及应用价值如下:
S-SMAJ30CA采用DO-214AC(SMA)贴片封装,具备以下实用优势:
基于双向防护、宽温范围及中低压参数,该器件适用于以下场景:
该器件由乐山无线电(LRC) 生产,LRC是国内知名半导体厂商,拥有数十年分立器件研发制造经验,产品符合RoHS、REACH等环保标准,封装工艺成熟,电气参数一致性好。
S-SMAJ30CA经过严格可靠性测试(温度循环、湿度老化、浪涌寿命测试等),可确保在长期使用中保持稳定防护性能,降低设备故障风险,适合对可靠性要求较高的商用与工业场景。
总结:S-SMAJ30CA是一款性价比高、适用场景广的双向TVS器件,双向防护、宽温设计与紧凑封装使其成为中低压电路过压防护的优选方案。

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.
