3.0SMCJ33CA_R1_00001 是 PANJIT(强茂)推出的一款双向瞬态电压抑制器(TVS),封装为 DO-214AB(SMC)。器件设计用于吸收电网浪涌与静电放电引起的高能瞬态,保护下游电子元件和电源系统。主要参数:反向截止电压 Vrwm = 33V,击穿电压 VBR = 42.2V,钳位电压 Vc = 53.3V(对应测试条件),峰值脉冲电流 Ipp = 56.2A(10/1000μs),峰值脉冲功率 Ppp = 3kW(10/1000μs),反向漏电流 Ir = 3μA,工作温度范围 -55℃~+150℃。
SMC(DO-214AB)为中功率表面贴装封装,具有良好的散热路径。实际应用中应尽量靠近可能受扰动的连接器或输入端放置 TVS,同时在焊盘设计中增大铜箔面积、添加热过孔或接地平铺,以利于脉冲能量分散与热耗散,避免反复高能脉冲导致器件过热。
器件工作温度范围宽(-55℃~+150℃),适合苛刻环境。尽管单次脉冲能力强,但不建议长期承受重复大能量冲击,必要时需进行脉冲能量管理与器件级联保护;使用前请参阅完整数据手册以获取浪涌测试条件、能量吸收曲线和寿命评估。采购时确认批次与温度系数要求,按实际系统余量选择合适 Vrwm 与钳位等级。

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.
