1N5919BRLG 稳压二极管产品概述

一、产品基本身份信息

1N5919BRLG是安森美(ON Semiconductor) 推出的独立式稳压二极管,属于通用型稳压器件。产品采用轴向DO-41封装,符合工业级插件安装规范,是电源电路、电压基准等场景的常用核心器件。

二、核心电气性能参数

该器件的电气参数经过严格标定,关键指标直接决定其应用场景:

  1. 稳压特性:标称稳压值为5.6V,实际工作波动范围为5.32V~5.88V(±5%公差),满足多数电路对稳压精度的基础要求;
  2. 反向漏电流:反向电压3V(远低于击穿电压)下,漏电流(Ir)仅5μA,静态损耗低,适合低功耗电路;
  3. 功率能力:最大耗散功率(Pd)为3W,可承受中等功率稳压场景,避免过载损坏;
  4. 动态阻抗:测试电流下动态阻抗(Zzt)仅2Ω,稳压线性度好,输出电压随负载波动小;
  5. 反向击穿前阻抗:击穿前阻抗(Zzk)为250Ω,确保未击穿时处于高阻状态,减少漏电流影响;
  6. 温度适应性:工作结温范围**-65℃~+200℃**,覆盖宽温区,可稳定工作于极端环境(如航空、工业高低温场所)。

三、封装与物理特性

1N5919BRLG采用轴向DO-41封装,具备以下物理优势:

  • 尺寸小巧:常规直径约2.7mm,长度约5.2mm,引线直径0.8mm,适合紧凑电路布局;
  • 材料可靠:玻璃-环氧树脂封装,绝缘性、耐腐蚀性强,机械强度高;
  • 安装便捷:轴向引出线兼容传统PCB通孔焊接,无需特殊设备,适合批量生产。

四、典型应用场景

基于电气参数和封装特性,该器件适用于以下场景:

  1. 电源稳压基准:为MCU、传感器等提供稳定5.6V参考电压,保障电路信号精度;
  2. 过压保护:利用反向击穿特性钳位瞬态过压,保护后端敏感器件(如通信模块、传感器);
  3. 仪器仪表参考源:在万用表、示波器中作为电压基准,提升测量精度;
  4. 工业控制电源:宽温范围+3W功率,适配变频器、PLC的辅助电源稳压模块;
  5. 通信设备辅助电路:基站、路由器中用于电压调节和浪涌抑制,应对复杂电磁环境。

五、产品优势与特点

  1. 高可靠性:安森美品牌器件经过温度循环、湿度老化等严格测试,故障率低,适合长期稳定工作;
  2. 宽温适应性:-65℃~+200℃结温范围,远超商用器件,可应对极端环境需求;
  3. 低损耗+高精度:5μA漏电流减少静态功耗,2Ω动态阻抗提升稳压精度,兼顾效率与性能;
  4. 易集成性:轴向DO-41封装兼容传统工艺,降低电路设计和生产难度。

六、使用注意事项

为确保器件稳定工作,需注意以下要点:

  1. 功率限制:耗散功率不得超过3W,需串联限流电阻(如负载电流100mA时,限流电阻≈50Ω);
  2. 极性识别:轴向封装中带色环端为阴极,需反向接入电路(稳压二极管工作于反向击穿状态);
  3. 焊接规范:焊接温度≤260℃,时间≤5秒,避免高温损坏器件;
  4. 结温控制:若电路功率较大,需加装散热片,避免结温超过200℃;
  5. 存储环境:存储温度-55℃~+150℃,湿度≤85%,避免长期暴露于潮湿环境。

该器件凭借平衡的性能与可靠性,成为工业、通信、仪器仪表等领域的经典稳压选择。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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.

Replenishment inquiry Typical RFQ workflow
