SMD2920-150/60N 是 BORN(伯恩半导体)推出的一款表面贴装型保险器,面向需在有限空间内实现过流保护的电子设备。器件基于 SMD 2920 封装设计,兼顾体积与热性能,适用于多种消费及工业电子应用的短时过流保护与自恢复保护场景。
该型号在正常工作时保持低阻抗,最大限度减少功率损耗与电压降;当电流超过 Itrip 并在动作时间内持续,器件进入高阻态以限制故障电流。随后在故障解除并冷却后可恢复到低阻态,用于可复位过流保护(自恢复)场合。Rmin 与 R1max 的指标可用于计算动作前后电压降和热耗散。
2920 SMD 封装适合自动贴装与回流焊工艺;出厂前应遵循厂商的焊接温度曲线与回流限制,避免超过规定的温度对材料性能造成影响。长期工作在高温或频繁动作场景会影响器件寿命,应在设计中留有裕量并考虑定期检测或替换策略。
SMD2920-150/60N 以其紧凑封装、明确的保持/跳闸特性及宽工作温度范围,是需要空间受限且要求可复位过流保护应用的可靠选择。选择与布局时,请结合系统实际电流波形与热条件做最终确认。

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.
