SS34C 产品概述
一、产品简介
SS34C 是 DOWO（东沃）推出的一款低压降、大电流整流二极管，采用 SMC 表贴封装，单只独立式结构。该器件针对开关电源、整流、反向保护及续流等应用进行了优化，兼顾低损耗与高浪涌承受能力，适合自动贴装生产线。
二、主要电气参数
- 正向压降 (Vf)：0.55V @ 3A（典型值）
- 直流反向耐压 (Vr)：40V
- 连续整流电流：3A
- 反向漏电流 (Ir)：500μA @ 40V
- 非重复峰值浪涌电流 (Ifsm)：70A
- 工作结温范围：-55℃ ~ +150℃
三、主要特性
- 低正向压降，降低导通损耗，提高系统效率；
- 高抗浪涌能力，能够承受启动/短路瞬态冲击；
- 低外形封装，适用于自动贴片（SMT）生产；
- 保护环（guard ring）设计，增强过压及边缘击穿耐受性；
- 符合 RoHS 要求，材料无卤，环保可靠。
四、典型应用场景
- 开关电源输出整流与续流二极管；
- DC-DC 转换器输入/输出整流；
- 电池充放电路径及反向保护；
- 适配器、电源模块、工控与通信设备的整流与保护电路；
- 对于一般汽车电子低压区段也可作为整流或保护元件（需按系统过压要求评估）。
五、封装与装配建议
- 封装：SMC 表贴，外形低矮，利于空间受限设计；
- 焊接：兼容无铅回流焊工艺，建议按厂家推荐的回流曲线进行；
- 散热：在额定连续电流下，器件功耗可达约 1.65W（0.55V × 3A），建议在 PCB 端使用较大铜箔面积与通孔散热，或在热沉区域安排散热铜箔/多层接地平面以降低结温，确保长期可靠性。
六、可靠性与合规
- 器件设计适应工业级工作温度范围（-55℃ 至 +150℃结温），适合宽温环境使用；
- 符合 RoHS 环保标准，材料无卤，满足现代电子产品的合规性需求；
- 推荐在出货之前结合实际应用条件（峰值电流、环境温升、脉冲次数等）做可靠性评估与寿命测试。
总结：SS34C（DOWO）以其低正向压降、3A 连续整流能力及 70A 峰值浪涌承受力，适合在多种电源与保护场景中替代传统整流器件。对于具体电路设计，建议参考完整数据手册以获取更详细的电气特性、封装尺寸与回流焊工艺参数。

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.
