BAT42W_R1_00001 产品概述

一、产品简介

BAT42W_R1_00001 是强茂(PANJIT)生产的一款肖特基势垒二极管,采用 SOD-123 小封装,面向需要低正向压降与快速切换特性的便携式与消费类电子应用。器件具有良好的浪涌承受能力与较低的反向漏电流,适合做整流、保护、限幅及混合信号检测等功能。

二、主要电气参数

  • 工作结温范围:-35 ℃ ~ +125 ℃
  • 正向压降 Vf:1.0 V @ 0.2 A
  • 直流整流电流(额定):200 mA
  • 非重复峰值浪涌电流 Ifsm:4 A(单次脉冲)
  • 直流反向耐压 Vr:30 V
  • 反向电流 Ir:500 nA @ 30 V(典型/测试条件)
  • 封装:SOD-123

以上参数为典型/额定值,具体应用时应参考强茂官方技术资料与器件曲线图。

三、关键特性与优势

  • 低正向压降:在 0.2 A 电流下 Vf 约为 1 V,可降低整流损耗并提高效率,尤其适用于低压电源路径或电池供电系统。
  • 低反向漏电:30 V 条件下 Ir 仅 500 nA,有助于在待机或低功耗模式下减少漏电损耗。
  • 良好浪涌承受能力:4 A 的单次峰值浪涌能力使器件可应对电源开关瞬态或突发浪涌电流。
  • 小型封装:SOD-123 体积小、适于高密度 PCB 布局,同时具备一定的焊接可靠性,适合自动化装配。

四、典型应用场景

  • 电源二次整流与保护:用于低压整流、反向保护或电源路径二极管,降低压降并延长电池续航。
  • 反向电池保护与肖特基 ORing:在多电源切换场景中作为高效的方向选择器。
  • 快速钳位与过压保护:配合 RC/LT 网络用于抑制尖峰脉冲。
  • 信号检波与混合信号前端:在高频或脉冲信号处理中发挥低压降与快速响应优势。
  • 便携式与消费类产品:如移动电源、充电设备、手持终端与小功率适配器。

五、设计与布局建议

  • 热管理:SOD-123 为小型封装,散热能力有限。若长期工作在较高电流或高环境温度下,应做好 PCB 散热(加大铜箔面积或使用热过孔)并进行功耗/温升评估。
  • 串联/并联使用:若需要更高的整流电流或更低压降,可考虑并联多只器件,但需注意电流均分与寄生电阻匹配。
  • 腔体和封装选型:在空间允许时,优先选择与 PCB 焊盘匹配的封装图样,严格按制造商推荐的焊盘尺寸与丝印标识布局。
  • 回流焊温控:遵循 PANJIT 的回流焊工艺规范(推荐曲线与峰值温度),避免超出热循环限制以免影响可靠性。

六、可靠性与使用注意事项

  • 温度影响:肖特基二极管的反向漏电流随温度升高显著增加,需在高温工况下验证漏电与功率损耗是否满足系统要求。
  • 浪涌规范:Ifsm 为非重复峰值浪涌能力,仅适用于短脉冲条件。反复浪涌或长时间高电流工作会降低器件寿命。
  • 存储与抗潮:按供应商说明进行防潮包装、存储及回流前烘烤处理,保证焊接可靠性与长期性能稳定。
  • 规格核对:量产前应在目标电路与典型环境下,依据完整数据手册(曲线、极限值、封装图)进行验证。

七、包装与采购信息

  • 品牌:PANJIT(强茂)
  • 型号:BAT42W_R1_00001
  • 封装:SOD-123,小体积、适合贴片自动化生产
  • 采购建议:索取最新数据手册确认完整电气特性与封装尺寸;批量采购前建议进行样片评估与热/电特性验证。

如需具体电气曲线(V‑I 曲线、温度特性、瞬态响应)、封装尺寸图或回流焊建议,可提供目标应用电流/工作温度以便给出更具体的设计建议与选型对比。

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
