XBS104V14R-G — TOREX (特瑞仕) 40V / 1A SOD-123 肖特基二极管产品概述
一、产品简介
XBS104V14R-G 是 TOREX（特瑞仕）推出的一款表面贴装肖特基整流二极管，封装为 SOD-123。该器件为单个独立二极管，面向空间受限的电源及开关应用，提供低正向压降和较好的浪涌承受能力，适用于各种中小功率整流、保护与续流场合。
二、主要电气参数
- 二极管类型：肖特基整流，单个独立式
- 最大直流整流电流（IF）：1 A
- 正向压降（Vf）：0.41 V @ 1 A
- 直流反向耐压（VR）：40 V
- 反向漏电流（IR）：2 mA @ 40 V
- 非重复峰值浪涌电流（Ifsm）：20 A（短脉冲）
这些参数表明 XBS104V14R-G 在 1A 工作点上具有很低的正向压降，有利于降低整流损耗；同时在短时冲击下有足够的浪涌承受能力。需要注意其在高反向电压下的漏电流相对较高，选型时应考虑工作电压与温度的影响。
三、封装与机械特性
- 封装形式：SOD-123（表面贴装）
SOD-123 封装占板面积小，适合自动贴装与回流焊加工。封装有助于散热到 PCB，适用于紧凑型电源模块与便携设备。选用时请参考厂商提供的焊盘推荐尺寸及回流曲线，以保证可靠焊接和热性能。
四、典型应用场景
- 开关电源（DC-DC）整流、续流二极管
- 电池充电器、移动设备电源管理
- 极性保护、倒灌保护与反向电压保护
- 输出整流、瞬态电流钳位与钳位保护
由于 Vf 低，XBS104V14R-G 特别适合需要降低功耗与发热的场合；在需要承受短时大浪涌（例如开机浪涌或电感反向冲击）的应用中，也能提供一定保护能力。
五、设计与使用建议
- 漏电流考虑：IR 为 2 mA@40 V，较高的反向漏电在高阻输入或休眠电路中会影响待机电流，应根据系统工作电压/温度评估实际漏电影响，必要时选用低漏电的替代型号。
- 热管理：尽管 SOD-123 有助散热，但在连续 1 A 工作时需考虑 PCB 散热、铜箔面积与过孔布置来降低结温。建议在板上为二极管旁留足铜箔并考虑热过孔。
- 浪涌能力：Ifsm=20 A 适合短脉冲浪涌（例如 8.3 ms 半正弦），但不适合长时间过流，需配合熔断或限流设计保护。
- 焊接与可靠性：遵循 TOREX 的回流焊曲线及焊盘设计，避免超过推荐温度与时长，以保证封装与电气性能稳定。
- 验证测试：在最终设计中进行温升与漏电随温度变化的验证，尤其是在高温或高工作电压条件下。
六、优势总结
XBS104V14R-G 结合了肖特基二极管的低正向压降与 SOD-123 的小型化封装，适用于对效率和版面空间有要求的中小功率应用。其短时 20 A 浪涌能力和 40 V 反向耐压，使其在多种电源保护与整流场合具有良好适应性。选型时需关注反向漏电与热设计，确保在目标应用下满足性能与可靠性要求。

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.
