SS34 产品概述
一、产品简介
SS34 是一款常用的肖特基势垒二极管，由扬杰(YANGJIE)生产，采用 SMC (DO-214AB) 封装，额定整流电流为 3A，直流反向耐压为 40V。肖特基二极管以其低正向压降和快速恢复特性著称，适合用于开关电源、DC-DC 变换、电池保护与整流等需要高效率与低损耗的场合。
二、主要技术参数
- 正向压降 (Vf)：约 700 mV @ 3 A（典型 0.7 V）
- 直流反向耐压 (Vr)：40 V
- 最大整流电流：3 A（连续）
- 反向漏电流 (Ir)：500 µA @ 40 V
- 非重复峰值浪涌电流 (Ifsm)：70 A
- 工作结温范围：-55 ℃ ~ +125 ℃
- 封装：SMC (DO-214AB)
以上参数为典型/额定值，具体选型时应参考厂家详细数据手册以确认工作条件与限值。
三、产品特点
- 低正向压降：0.7 V 左右，有利于降低整流及开关损耗，提高系统效率。
- 快速响应：肖特基结构带来极短的恢复时间，适合高频开关环境。
- 高浪涌承受能力：70 A 峰值浪涌电流，满足瞬态大电流冲击要求。
- 宽温度范围：工作结温 -55 ℃ 到 +125 ℃，适用工业级环境。
- 封装可靠：SMC/DO-214AB 提供良好散热面积，便于 PCB 热设计。
四、典型应用场景
- 开关电源（SMPS）次级整流与自由轮二极管。
- DC-DC 转换器整流与续流路径。
- 充电与电源管理电路，降低功耗与发热。
- 电池保护、电源切换与反向保护。
- 一般 12V / 24V 电源系统中进行整流与防反接使用（在高压或特殊汽车瞬态条件下请按规范验证）。
五、封装与热管理
SMC (DO-214AB) 封装具有较大的焊盘面积和散热面，便于将热量传导至 PCB。设计时建议：
- 在 PCB 布局中提供适当的铜箔散热区（底层或多层过孔连接）。
- 根据实际散热需求选择合适的焊盘尺寸与过孔数量。
- 考虑到正向压降引起的功耗 P ≈ Vf × I，在持续 3A 工作下约 2.1 W，需评估结温并保证在额定范围内。
六、可靠性与使用注意事项
- 在高温或高反向电压下，漏电流会增加，应留有裕量。
- 浪涌电流虽高，但重复或长期超限会降低器件寿命，应避免频繁大幅冲击。
- 焊接时遵循厂商推荐的回流曲线，避免过热影响可靠性。
- 储存与搬运时注意防静电与防潮，开封后若未即刻使用建议回潮烘烤处理。
总结：扬杰 SS34（SMC 封装）是一款性能均衡、适用面广的 40V/3A 肖特基整流二极管，适合追求低损耗与高频特性的电源及保护电路。选型时请参考完整的数据手册并根据实际应用的电流、温度和浪涌条件进行热设计与可靠性评估。

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.
