DB107S 整流桥产品概述

一、产品简介

DB107S 是富芯森美(FUXINSEMI)推出的一款单相整流桥,封装为 DBS,面向通用电源整流应用。该器件由四只硅整流二极管组成,设计用于交流到直流的整流转换,具有高耐压、稳定的直流整流能力及良好的浪涌承受能力,适用于家用电器、工业电源及通用模块化电源设计。

二、主要参数

  • 正向压降 (Vf):1.1 V @ 1 A(单只二极管)
  • 直流反向耐压 (Vr):1000 V
  • 平均整流电流:1 A
  • 反向电流 (Ir):10 μA(典型测试条件)
  • 非重复峰值浪涌电流 (Ifsm):30 A
  • 工作结温范围:-55 ℃ ~ +150 ℃
  • 封装:DBS(整桥封装)
  • 类型:单相整流桥

三、特性与优点

  • 高耐压能力:1 kV 的反向耐压适合高电压输入或脉冲冲击较大的场合,提供良好的安全裕度。
  • 稳定的整流性能:1 A 的平均整流电流满足多数中低功率电源的要求;在瞬态条件下 30 A 的峰值浪涌能力保证充电、上电瞬间的安全性。
  • 低漏电流:10 μA 级别的反向电流在多数待机和高阻抗回路中有利于降低静态功耗。
  • 宽温度范围:-55 ℃ 到 +150 ℃ 的结温范围适合多种恶劣环境及工业级应用。
  • 封装紧凑,便于 PCB 布局和机械安装。

四、典型应用场景

  • 开关电源(对输入二次整流或辅助电源)
  • 线性电源适配器与充电器的整流部分
  • 小功率工业电源、仪器仪表电源
  • 家用电器、照明电源的AC→DC转换
  • 作为保护或整流组件嵌入电源模块

五、封装与热性能

DBS 封装便于焊接和散热,但在连续 1 A 工作条件下仍建议考虑散热管理。器件的结温受功耗(主要由正向压降与电流产生)影响明显,建议在 PCB 设计时增加铜箔面积以降低结温,或在高环境温度和长时间满载工作时采用散热片或强流通风条件。

六、使用建议与注意事项

  • 正向压降为 1.1 V(1 A),整桥导通时典型压降为两只二极管串联值,应在电压降和功耗预算中考虑两倍 Vf。
  • 对于高频整流或对反向恢复时间敏感的电路,建议选用快恢复或肖特基二极管以降低开关损耗与电磁干扰;DB107S 更适用于工频及低频整流场合。
  • 选型时保留足够的反向耐压裕度,防止瞬态尖峰超过 1 kV 而产生击穿。必要时配合抑制器件(如 TVS、RC 抑制网络)使用。
  • 长期工作环境温度高于 25 ℃ 时应按厂商热阻及结温限制进行电流降额,以保证可靠性。

七、品质与可靠性

富芯森美生产工艺与品质控制适配于工业级应用,器件经过常规环境与电气应力测试。推荐在量产前参考完整数据手册进行温度场、老化加速及电气应力试验,以验证在具体应用中的长期可靠性。

总结:DB107S 以其 1 A 的整流能力、1 kV 的高耐压和 30 A 的冲击承受力,适合通用电源与中低功率整流场景。合理的散热与电路保护设计可进一步提升系统稳定性与寿命。若需完整的电气特性曲线、引脚定义或封装尺寸图,请参考富芯森美官方数据手册或联系供应商获取样片验证。

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
