DL4746A_R1_10001 产品概述
一、产品简介
DL4746A_R1_10001 是强茂（PANJIT）出品的一颗独立式稳压二极管，封装为轴向 DL-41（类似 DO-41）。标称稳压值为 18V，公差 ±5%，稳压值范围 17.1V ~ 18.9V。器件设计用于作为精密电压参考、稳压与过压钳位等低功率场合的稳压元件。
二、主要电气参数
- 稳压值（标称）：18V（±5%）
- 反向电流 Ir：5 μA @ 13.7V（典型泄漏小，适合高阻负载）
- 最大耗散功率 Pd：1W（封装与散热条件相关）
- 稳压阻抗 Zzt：20 Ω（表征在测试电流下的动态阻抗）
- 阈/膝阻抗 Zzk：750 Ω（低电流区的特性，影响低电流下的稳压质量）
- 工作结温范围：-65°C ~ +200°C
三、产品特性与优势
- 低泄漏：在 13.7V 条件下反向电流仅 5 μA，有利于保持高阻抗回路的稳定。
- 适中功率能力：1W 额定耗散满足多数小功率稳压及基准应用。
- 宽温度范围：-65°C 至 +200°C 的结温范围，适应工业级及严苛环境。
- 稳压精度 ±5%：适合需要一定精度但对成本敏感的应用场景。
四、典型应用
- 低功耗参考电压源与分流式稳压器
- 电源噪声抑制与电压钳位保护
- 仪表与传感器前端的基准稳压
- 工业控制与通信设备中的局部稳压电路
五、使用建议与热管理
- 建议工作于额定功率以下并考虑热降额：在环境温度升高或散热受限时，应按线性降额方式限制耗散功率以保持器件结温安全。
- 轴向 DL-41 封装通过良好的 PCB 布局与散热铜箔可以改善散热性能。
- 在电路设计中配合合适的串联电阻以控制电流，避免在轻载或过载状态下器件进入过高耗散。
- 焊接与装配时注意不要超出封装允许的温度与时间，避免长期高温降低可靠性。
六、封装与选型信息
- 品牌：PANJIT（强茂）
- 封装：DL-41（轴向）
- 产品分类：稳压二极管（未分类）
在订购与替换时，请核对稳压值、公差、功率与封装尺寸，确保与系统热设计及性能要求匹配。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
