SS34（GOODWORK 固得沃克）肖特基二极管 产品概述
一、产品简介
SS34 是一款单个独立封装的肖特基势垒二极管，由 GOODWORK（固得沃克）品牌生产，封装为 SMA（DO-214AC）。该器件面向需要低正向压降与快速开关响应的功率整流与保护应用，额定直流整流电流为 3A，直流反向耐压 40V，适合各种中功率电源及汽车、工业与消费电子场景。
二、主要电气参数
- 工作结温范围：-65℃ 至 +150℃
- 直流整流电流（IF）：3A
- 正向压降（Vf）：0.55V @ 3A
- 直流反向耐压（VR）：40V
- 反向漏电流（IR）：50µA（典型/条件见厂方资料）
- 非重复峰值浪涌电流（Ifsm）：80A
以上参数表明 SS34 在高电流瞬态条件下具有良好承受能力，同时保持较低的导通损耗，适用于高效率整流场合。
三、产品特点
- 低正向压降：0.55V @ 3A 降低导通损耗，提升电源效率，降低发热。
- 快速响应：肖特基结特性使得反向恢复极小，适合高频开关电源。
- 宽温度范围：支持 -65℃ 至 +150℃，可靠性高，适应恶劣环境。
- SMA 封装：体积小、易于自动贴装与回流焊接，适合批量生产。
四、典型应用
- 开关电源（整流、续流二极管）
- DC-DC 降压转换器输出整流
- 电源反向保护与 ORing 电路
- 汽车电子（车载充电、车灯驱动等）——须满足车规认证要求
- LED 驱动与充电器
- 通信设备与电池管理模块
五、封装与装配建议
- 封装型号：SMA（DO-214AC），适配常用 SMA PCB 尺寸及丝印。
- 焊接工艺：推荐采用标准回流焊温度曲线，遵循无铅/有铅工艺要求以避免热应力损伤。
- 散热建议：尽管器件支持 3A 连续电流，实际应用中应根据 PCB 铜箔面积与周围元件散热条件进行功耗分配与适度降额；必要时增加散热铜层或散热块。
六、可靠性与使用注意
- 注意反向漏电：在高温或高反向电压下，漏电流会增大，设计时预留裕量。
- 冲击电流处理：非重复峰值浪涌 80A 能承受短时冲击，频繁大电流冲击会影响寿命，建议避免长期过冲。
- ESD 与过压防护：在易受干扰场景建议配合 TVS 或其他抑制器件提高系统可靠性。
- 存储与焊接：在焊接前遵循厂方干燥与封装开封时间规定，防止潮湿引起焊接缺陷。
七、选型与替代方案
SS34 以其 40V、3A、低 Vf 的组合，适合大多数中功率整流场合。如需更高耐压或更低正向压降的方案，可考虑更高电压等级或采用并联/选择不同封装的肖特基器件。选择时应参考完整数据手册中的温升曲线、反向恢复特性及热阻等详细参数。

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.
