SMD1206-200/16N 产品概述
一、概述
SMD1206-200/16N 为 BORN（伯恩半导体）推出的 1206 封装可恢复自恢复保险丝（PPTC），额定保持电流 2A，额定耐压 16V。器件尺寸为 3.4mm × 1.8mm × 1.3mm，适用于空间受限的表贴电路板，为电源线、USB、便携设备和板级保护提供重复保护功能。
二、主要参数
- 额定耐压 (Vmax)：16V
- 最大电流 (Imax)：40A（瞬态或短路条件下的最大承受值）
- 保持电流 (Ihold)：2A（器件在不动作时能长期承受的电流）
- 跳闸电流 (Itrip)：4A（在标准条件下触发动作的典型电流）
- 消耗功率 (Pd)：800mW（在 25°C 附近的最大功耗）
- 初始态阻值 (Rmin)：18mΩ（冷态低阻，影响压降）
- 跳断后阻值 (R1max)：100mΩ（动作后限制电流的高阻）
- 动作时间：500ms（在指定过流条件下的参考动作时间）
- 工作温度：-40°C ~ +85°C
- 封装：1206（SMD），尺寸 3.4 × 1.8 × 1.3 mm
- 品牌：BORN（伯恩半导体）
三、工作原理与关键术语说明
该器件为聚合物正温度系数（PPTC）自恢复保险丝。正常工作时呈低电阻（Rmin），通过较小电压产生最小发热；当电流超过 Itrip 或在高于指定时间累积能量时，器件内部加热使电阻迅速上升至跳断后阻值（R1max），从而限制故障电流。故障消除并冷却后可自动恢复到初始低阻态。Ihold 与 Itrip 的选择需参考环境温度与 PCB 热散条件。
四、典型应用场景
- USB 供电保护（便携设备、外设）
- 电池供电设备与电源管理模块的短路/过流保护
- LED 驱动器与小功率电源轨保护
- 家电控制板、工业控制板的板级保护（非高温发动机舱）
注意：工作温度上限为 +85°C，若用于高温环境需做额外热管理或选用更高温等级器件。
五、封装与安装建议
- 与标准 1206 焊盘兼容，建议采用常规 SMT 回流焊工艺（请遵循厂商回流曲线，避免长时间超过峰值温度）。
- PCB 布局时注意周围铜箔面积与散热环境会显著影响动作电流与时间：大铜箔有利散热会提高动作电流/延长动作时间。
- 留足电气间距与机械空间以利于散热和避免邻近元件受热影响。
六、可靠性与使用注意事项
- 选型时建议给予 20%~50% 电流裕度，避免长期在靠近 Ihold 的边界工作以延长寿命。
- 测试时务必在目标应用的真实温度和 PCB 条件下验证 Ihold 与 Itrip。
- 避免在超过规范的持续过载下使用，防止不可逆损坏。存储环境应干燥、避免强光与高温潮湿。

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.
