BT138S-800E 产品概述
一、概述
BT138S-800E 是一款适用于交流断续与相位控制的双向可控硅（TRIAC）模块，由 FUXINSEMI（富芯森美）生产，封装为 TO-252。器件工作温度范围宽 (-40℃ 至 +125℃)，设计用于耐受高电压与瞬态浪涌，适合家电、照明调光、加热器与电机速度控制等典型交流功率控制场景。
二、主要电气特性
- 断态峰值电压（Vdrm）: 800 V
- 通态峰值电压（Vtm）: 1.55 V
- 通态电流（It）: 12 A（连续额定）
- 浪涌电流: 95 A @ 50 Hz（可承受短时浪涌）
- 保持电流（Ih）: 30 mA
- 门极触发电流（Igt）: 10 mA
- 门极触发电压（Vgt）: 1.3 V
- 门极平均耗散功率（PG(AV)）: 500 mW
三、关键特性与优势
- 高耐压（800V）适应市电及工业环境中的过压要求。
- 低通态电压降（Vtm≈1.55V），有利于降低导通损耗与发热。
- 较强的浪涌能力（95A）可应对负载启动冲击。
- 宽工作温度范围，适合多种环境应用。
- TO-252 紧凑封装，便于模块化设计与散热处理。
四、封装与热管理
TO-252 封装体积小，导热面积有限。建议在连续 12A 工作时配合热垫或小型散热片使用，并注意按数据手册进行功耗与结温计算。门极驱动应避免长时间大电流脉冲，门极功耗 PG(AV) 仅 500 mW，需注意驱动电阻与触发脉冲宽度。
五、典型应用
- 灯光调光与相位控制
- 小功率交流电机速度控制
- 家用电器（烘干机、微波炉等）功率开关
- 固态继电器与功率控制模块
六、使用注意事项
- 设计时需加 RC 抑制网络以控制 dv/dt 和抑制振铃；对于感性负载，建议并联触发电阻或 snubber。
- 保持电流（Ih）较高，低电流工况下可能导通不稳定，应确保负载电流超过 Ih。
- 触发电流（Igt）与触发电压（Vgt）对驱动电路要求明确，建议留有裕量以保证可靠触发。
- 在高浪涌或反复开关场合需考虑热循环与长期可靠性影响，必要时做额外试验验证。

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.
