SMBJ36CA 产品概述

一、主要参数与特性

SMBJ36CA(RUILON/瑞隆源)是一款双向瞬态电压抑制(TVS)二极管,关键参数如下:钳位电压58.1V;工作温度范围-55°C ~ +150°C;击穿电压(Vbr)46V;反向截止电压(Vrwm)36V;峰值脉冲功率600W(10/1000µs);峰值脉冲电流Ipp 10.3A(10/1000µs);反向漏电流Ir 1µA;防护等级符合IEC 61000-4-4与IEC 61000-4-2;封装为DO-214AA(SMB),极性为双向。该器件适合对中高能量瞬态浪涌进行保护。

二、功能与典型应用

SMBJ36CA适用于24V/36V直流系统及需要双向保护的场合,例如工业控制电源输入、继电器驱动线路、通讯接口、逆变/太阳能微逆变器前端、车载外围电路(非关键安全回路)及一般工业设备的浪涌保护。双向结构使其在交流或极性不确定的场合表现优越。

三、工作原理与性能说明

在正常工作时,器件在Vrwm(36V)以下表现为高阻态,漏电流极低(典型1µA),不会影响电路。遇到瞬态过压时,器件进入雪崩导通,限流并将电压钳位到约58.1V,从而吸收脉冲能量(600W@10/1000µs,Ipp 10.3A),保护后端器件不被高电压击穿。

四、封装与热管理

DO-214AA(SMB)封装便于表面贴装与手工焊接,具有较好的热耗散能力。为了保证器件在多次或高能量冲击下性能可靠,建议在布局上将TVS尽量靠近入线端并缩短引线长度,增大铜箔面积或使用散热通孔以提高热扩散能力。

五、认证与可靠性

器件通过IEC 61000-4-2(静电放电)和IEC 61000-4-4(快速瞬变/脉冲群)等级认证,可满足工业级抗扰度要求。额定工作温度宽(-55~+150°C),适合苛刻环境使用,但需遵循能量循环与峰值限制,避免超规格重复冲击。

六、选型与工程注意事项

  • 确认工作电压不得超过Vrwm(36V);若系统工作电压接近或高于36V,应选择更高Vrwm等级。
  • 钳位电压58.1V为在规定脉冲条件下的典型值,设计时留有足够余量保护后级器件。
  • 对频繁高能冲击场合,考虑并联或选用更高Ppp等级器件,并配合熔断器/限流元件。
  • 双向TVS适合交流或极性不定线路;若为恒定极性直流,单向型通常有更低的钳位电压和漏电。

七、焊接与存储建议

遵循SMB封装的回流温度规范,避免长时间高温暴露;未使用元件应按防潮包装存放,避免湿气影响焊接质量。器件属于静电敏感元件,装配和测试时应采取ESD防护措施。

八、结语

SMBJ36CA凭借600W能量吸收能力、双向保护与工业级温度范围,是24V/36V级别系统中可靠的浪涌保护选择。在实际应用中,合理的PCB布局、热管理与与系统电压匹配是发挥其最佳保护效果的关键。若需进一步的曲线图或详细规格参数(如Vbr测试电流、钳位电压随脉冲电流的变化曲线),建议参考厂商完整数据手册或联系RUILON技术支持。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
