P0300SB 是一款由台湾君耀(Brightking)公司生产的高性能半导体放电管(Thyristor Surge Suppressor, TSS),采用 SMB(DO-214AA)封装。该产品专为保护电子设备免受瞬态电压和电流冲击而设计,广泛应用于通信、工业控制、消费电子等领域。
P0300SB 适用于多种需要过压保护的场合,包括但不限于:
P0300SB 是一种双向可控硅(Thyristor)器件,其工作原理基于 PNPN 结构。在正常工作电压下,TSS 处于高阻态,几乎不导通电流。当电路中出现瞬态过压时,TSS 迅速切换到低阻态,将过压能量泄放到地,从而保护后端电路。一旦过压消失,TSS 会自动恢复到高阻态,继续正常工作。
P0300SB 采用 SMB(DO-214AA)封装,具体尺寸如下:
这种紧凑的封装使得 P0300SB 在空间受限的应用中也能轻松集成。
P0300SB 是一款高性能、高可靠性的半导体放电管,适用于多种需要过压保护的场合。其快速响应、低漏电流和小封装等特点,使其成为电子设备保护电路中的理想选择。无论是在通信、工业控制还是消费电子领域,P0300SB 都能提供可靠的过压保护,确保设备的安全运行。

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.
