BT169D 产品概述
一、概述
BT169D 是一款单向晶闸管（可控硅），由 FUXINSEMI（富芯森美）推出，采用常见的 TO-92 直插封装，面向低功率交流/直流控制应用。器件具有较低的门极触发电流和较小的保持电流，适合对触发灵敏度有要求的小信号负载控制场合。
二、主要性能与参数
- 断态峰值电压 Vdrm：600 V
- 通态电流 It（额定）：800 mA
- 浪涌电流：8 A @ 50 Hz（单次浪涌能力，参考厂方脉冲规范）
- 门极平均耗散功率 PG(AV)：100 mW
- 通态峰值电压 Vtm：1.5 V（在额定电流下的压降峰值）
- 门极触发电流 Igt：200 µA（典型）
- 门极触发电压 Vgt：800 mV（典型）
- 保持电流 Ih：4 mA
- 封装：TO-92；品牌：FUXINSEMI（富芯森美）
三、典型应用
- 小功率灯光调光（相位切割）
- 小电流交流负载控制与整流侧开通
- 测试与保护电路（如可控启动、软启动）
- 小型交流电机转速控制与电子开关替代继电器
四、设计与使用要点
- 触发电路：门极触发电流仅 200 µA，门极灵敏，建议通过合适的门极电阻限制瞬态电流，并考虑抗噪滤波以避免误触发。
- 热管理：额定通态电流 800 mA，TO-92 封装散热能力有限；长时间大电流工作需降低电流幅值或采用散热措施并参照厂方热阻与结温限制进行额定值降额。
- 浪涌容限：标称 8 A @50Hz 的浪涌能力适合短时冲击，但不能作为重复脉冲额定值，设计时考虑限流或使用熔断/保护电路。
- 抗干扰与保护：在感性负载或有高 dv/dt 场合，建议并联 RC 吸收（snubber）或 TVS 保护，防止误触发与过压损坏。
- 焊接与可靠性：TO-92 直插器件易焊接，焊接温度和时间应遵循标准焊接曲线以保护器件内部结构；存储与安装注意静电防护。
五、封装与购置建议
BT169D 以 TO-92 单体封装供应，适用于原型与批量小批量装配。购买时建议索取并参照富芯森美完整数据手册以确认引脚排列、热阻、时限脉冲曲线（I2t）、包装形式及环境温度范围等详细规范，便于电路选型与可靠性评估。
本概述以器件典型参数与应用实践为导向，便于在设计初期快速评估 BT169D 是否满足系统需求；具体极限值与曲线应以厂方数据手册为准。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
