DL4749A_R1_10001 产品概述

一、产品简介

DL4749A_R1_10001 是强茂(PANJIT)出品的独立式稳压二极管,标称稳压值为 24V,适用于要求小功率、可靠稳压和浪涌钳位的各类电子设备。器件采用 DL-41 封装,结构紧凑,便于 PCB 布局与手工焊接。

二、主要参数与电气特性

  • 稳压值(标称):24V;允许范围:22.8V ~ 25.2V。
  • 反向电流 Ir:5μA @ 18.2V(低漏电特性,利于保持稳定参考)。
  • 耗散功率 Pd:1W(器件在良好散热条件下的最大耗散能力)。
  • 阻抗 Zzt(稳态阻抗):25Ω;阻抗 Zzk(动态/低电流处):750Ω。
  • 工作结温范围:-65℃ ~ +200℃,适应宽温度环境与高温工艺要求。
  • 封装:DL-41(独立式),品牌:PANJIT(强茂)。

三、主要特点

  • 稳压精度较好,输出电压在标称值附近波动小,适合作为参考源或局部稳压。
  • 低漏电流,有利于低功耗电路与高阻抗参考电路设计。
  • 阻抗参数清晰,方便估算负载影响与瞬态响应。
  • 宽温度与高结温能力,适合工业级与恶劣环境应用。
  • 小功率封装便于空间受限的电路板设计。

四、典型应用场景

  • 直流电源的局部稳压与参考(如 24V 旁路/辅助稳压)。
  • 抗干扰与浪涌钳位电路,保护后级敏感器件。
  • 汽车电子、工业控制、通信设备中的电压基准或保护元件。
  • 测试平台与教学电路中的标准稳压元件。

五、热性能与封装注意

DL-41 小型封装在 1W 功耗下对散热依赖明显,推荐在 PCB 上配备散热铜箔或通孔连接大面积地/电铜以提高散热效率。长期可靠工作时应按厂商热阻与环境温度进行功率降额,以避免结温超过允许范围。

六、设计与使用要点

  • 使用时通常串联限流电阻来控制二极管反向电流与功耗,计算时以最低工作电流和最大输入电压为依据。
  • 注意 Zzk 与 Zzt 表征的不同工作区间,低电流时阻抗较大,稳压能力下降,需保证工作点在合理电流范围内。
  • 在高温或长时间工作场合应考虑散热设计与必要的保护电路。

七、品质与采购提示

PANJIT(强茂)品牌在稳压二极管领域具有成熟制造与质量控制,适合要求稳定性与一致性的工程项目。订购时请确认完整料号 DL4749A_R1_10001、封装 DL-41 及所需的测试与出货文件(如必要的质量检验报告或规格书)。

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
