DB307S 产品概述

一、产品简介

DB307S 为 GOODWORK(固得沃克)出品的单相整流桥,采用 DBS 封装,面向中高压直流整流应用。器件在3A工作电流点具有较低正向压降,同时具备1kV的重复反向耐压和良好的浪涌承受能力,适用于要求可靠性与耐压性能并重的电源设计。

二、主要电气参数

  • 正向压降 (Vf):1.1V @ IF=3A
  • 直流反向耐压 (Vr):1000V
  • 整流电流 (IF):3A(连续)
  • 反向电流 (Ir):5µA @ VR=1000V
  • 非重复峰值浪涌电流 (Ifsm):80A
  • 工作结温范围:-65℃ ~ +150℃
  • 类型:单相整流桥;封装:DBS

三、关键特性与优势

  1. 低正向压降:在3A工作点1.1V的正向压降可降低功耗与发热,有利于提升系统效率。
  2. 高耐压与低漏电:1kV耐压配合5µA@1000V的低反向电流,适合高压整流与高阻抗负载场合。
  3. 强浪涌承受:80A的峰值浪涌能力,可应对启动冲击与短时过载。
  4. 宽温度范围:-65℃至+150℃的结温等级适合苛刻环境与工业级应用。

四、典型应用场景

适用于开关电源整流、整流模块、工业控制电源、高压直流电源、LED 驱动、仪器仪表及其他需要中高压可靠整流的场合。对于需要减小漏电和提高隔离耐压的设计尤为合适。

五、使用与热管理建议

  • 采用适当的散热措施:DBS 封装导热受限,推荐加装散热片或优化 PCB 铜箔面积与热镀通孔以降低结温。
  • 允许的连续电流应根据实际环境温度和散热条件进行降额;在高环境温度或有限散热时建议降低额定电流。
  • 在有较大反向应力或脉冲干扰的系统中,建议并联抑制器件(如 TVS)或在输入端增加限流器件以保护整流桥。
  • 焊接与回流时遵循常规元件温度曲线,避免超过封装允许温度并防止机械应力。

六、可靠性与注意事项

  • 注意极性连接错误可能导致器件损坏。
  • 长期在高压、高温环境下工作会加速老化,应留有裕量并进行温升验证。
  • 对于关键系统,建议进行整机级浪涌与耐压测试以确认设计稳健性。

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
