RS1B 是江苏长电(CJ)推出的一款快恢复/高效率整流二极管,单只独立封装,型号常用于中低功率整流与开关恢复场合。器件设计侧重在较低正向压降与可控的反向恢复特性之间取得平衡,适合需要兼顾效率与成本的电源、马达驱动及保护电路。
RS1B 采用 SMAJ 封装,适合自动贴装与回流焊工艺,兼顾体积与散热能力。SMAJ 封装便于在紧凑电路板上实现多点布置,同时允许在一定程度上通过 PCB 铜箔进行散热管理。典型应用中无需额外散热器,但在高平均电流或高开关损耗场景下应合理增大铜箔面积或采用散热措施。
RS1B 的工作结温范围为 -55 ℃ 至 +150 ℃,适应工业级温度需求。非重复峰值浪涌电流为 30 A,适合短时浪涌保护,但不适合长期超额负载。使用前建议阅读厂方完整数据手册,关注最大额定值、热阻、典型曲线(Vf-T、Ir-V、Trr 与 di/dt 相关特性)以及推荐的回流焊温度曲线。最后,实际产品可靠性受 PCB 设计、冷却条件和实际工作环境影响,关键应用应做足温升和寿命评估。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
