PT908-7C(BIN4) 是台湾亿光(EVERLIGHT)出品的通孔红外光敏晶体管,采用 NPN 结构,针对 860nm 附近的红外光具有良好响应。器件灵敏、暗电流低,适合短距离红外检测与开关应用(如遥控接收、对射/反射传感、编码器与光电隔断等)。封装为插件式,管长 L = 4.5mm,便于手工与波峰/通孔工艺组装。
PT908-7C 为通孔(插件)封装,管长 4.5 mm,适合传统 PCB 插装与手工焊接工艺。工作温度 -25 ℃ 至 +85 ℃,在恶劣环境(高湿、高温、有腐蚀性气体)中应采取防护措施(涂覆、密封或选择适配外壳)。
PT908-7C(BIN4) 属于标准低电流红外光敏晶体管系列,若需更高电流或更高功率耗散,应考虑其他型号或改用光电二极管配合运放/比较器的方案。选型时关注峰值波长、暗电流、最大 Ic 与 Pd 三者的匹配,确保在目标应用的光照与电源条件下工作在安全区间。
总之,PT908-7C(BIN4) 以其低暗电流、良好 860 nm 响应和通孔封装,适合多种短距红外感测与开关场合。设计时应优先考虑功耗和热限制,合理选择负载与光学配合,以保证稳定可靠的系统性能。

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.
