DB307S 产品概述
一、产品简介
DB307S 为钜兴（JUXING）出品的单相整流桥，属于DBS封装系列。该器件额定整流电流3A，设计用于交流-直流整流场合，适配工业电源、家用电器、小型开关电源及电池充电等应用。器件工作结温范围宽 (-55 ℃ 至 +150 ℃)，可满足严苛温度环境下的长期运行。
二、主要参数
- 型号：DB307S
- 类型：单相整流桥（桥式整流）
- 正向压降 Vf：1.1 V @ 3 A
- 额定整流电流：3 A（DC）
- 非重复峰值浪涌电流 Ifsm：80 A
- 直流反向耐压 Vr：1000 V
- 反向电流 Ir：5 μA @ 1000 V（常温标称）
- 工作结温范围：-55 ℃ ～ +150 ℃
- 封装：DBS
- 品牌：JUXING（钜兴）
三、特性与优势
- 低正向压降：1.1 V 在3A条件下有利于降低整流损耗和发热，提升整机效率。
- 高耐压性能：1 kV 反向耐压适合高压输入或有较大电压应力的电源系统。
- 良好浪涌能力：80 A 的非重复峰值浪涌电流可应对启动瞬态和充电冲击。
- 宽温度范围：适配工业级与户外设备的温度需求。
- 低反向漏流：5 μA @1kV 在高压条件下漏电小，有利于降低静态功耗和维持电压稳定。
四、封装与热管理
DBS 封装体积小且便于安装，但热阻相对较高。芯片在高电流或高环境温度下仍需可靠散热设计。建议在 PCB 上配合充足铜箔面积、热过孔或外加散热片使用，并遵循厂商的结温-环境温度导则进行电流热额定降额。
五、典型应用
- 交流输入的直流电源整流
- 工业控制与驱动电源
- 小型开关电源和适配器
- 电池充电器与功率模块
六、可靠性与使用要点
使用时应留有足够的耐压余量，防止尖峰电压导致击穿；注意高温下反向漏流随温度上升而增加，必要时进行温度测量和电流监控；浪涌电流为非重复峰值，若系统存在反复冲击需采取限制措施或选用更高浪涌等级器件。选型时参考整流电流、散热条件及线路浪涌特性，确保长期稳定运行。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
