BTS3046SDL是英飞凌推出的单通道低侧功率开关,专为中小功率负载的智能控制设计,集成多重保护功能,适配汽车电子、工业控制等对可靠性要求较高的场景。其核心优势在于宽电压范围、低导通电阻与宽温适应性,无需外部额外保护电路即可实现负载的安全通断控制。
BTS3046SDL属于低侧功率开关(负载串联在电源与开关输出端之间,开关直接连接系统地),仅需1个通道即可实现单负载的精准控制。控制逻辑为高电平有效:当控制输入(IN)引脚接≥2V高电平时,开关导通;接≤0.8V低电平时,开关关断,无需复杂的驱动电路即可与MCU/PLC等数字控制器直接匹配。
BTS3046SDL集成3种关键保护,无需外部元件即可避免负载异常对器件的损坏:
当芯片结温超过典型阈值175℃时,自动关断输出;温度降至安全范围(约150℃)后自恢复导通,无需手动重启,有效防止热击穿。
当输入电压(Vcc)超过最大允许值11V时,立即关断输出,避免过压损坏内部MOSFET管。
输出端短路时,自动限制输出电流至安全水平(≤3.6A),避免大电流烧毁器件;短路解除后自恢复导通,提升系统容错性。
采用PG-TO252-3封装(表面贴装型,3引脚),体积小巧(约6.5×4.5mm),散热性能优于SOT-23等小封装,适合高密度PCB设计。引脚定义清晰:
BTS3046SDL凭借集成多重保护、宽电压范围、低导通电阻与宽温适应性,成为中小功率负载智能控制的理想选择,尤其适用于汽车电子、工业控制等对可靠性要求苛刻的场景,可简化电路设计、降低系统成本。

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