SMF20CA 是一款二极管,属于瞬态抑制二极管(TVS Diode)的类别,常用于电压抑制和过压保护。该产品由台湾迪嘉(TWGMC)制造,采用 SOD-123FL 封装,具有良好的热性能和电气性能,广泛应用于各种电子设备中以保护敏感元件免受电涌和过电压损害。SMF20CA 采用高性能材料制造,保证其在极端工作条件下的可靠性和稳定性。
额定电压(V_RWM): SMF20CA 的最高工作电压为 20V。此电压等级使其特别适用于低压电路中,用于保护电子设备免受突波电压的影响。
击穿电压(V_BR): 在特定的测试条件下,该元器件的击穿电压范围通常在 22V 至 25V 之间,这为主要被保护的电路提供了充分的保护余地。
峰值脉冲功率(P_P): SMF20CA 的峰值脉冲功率可达 400W(在 8/20μs 波形下),这使得它可以在瞬态过电压和电流异常情况下有效地消耗多余的能量。
反向漏电流: SMF20CA 在标称的工作电压下,反向漏电流相对较低,一般为几微安,延长了电路的使用寿命并降低了功耗。
封装特性: SOD-123FL 封装体积小,适合高密度布板设计,且有良好的焊接性能和散热能力。该封装的尺寸大约为 2.6mm x 1.6mm x 1.1mm,便于在狭小空间内集成。
SMF20CA 由于其优异的电气特性和小巧的封装,广泛应用于多种电子设备,如:
消费类电子产品: 包括智能手机、平板电脑和个人电脑,SMF20CA 可以防止因外部冲击或电源波动导致的设备损坏。
通讯设备: 在基站、路由器等通讯设备中,用以保护敏感的信号处理模块,防止静电放电(ESD)和电压瞬变对电路的影响。
工业设备: 在工业控制和自动化设备中,SMF20CA 能有效地保护控制电路,确保设备的长期稳定运行。
汽车电子: 随着汽车电子化的发展,SMF20CA 也逐渐被用于汽车电子控制单元(ECU)中,以防止高压冲击对电控系统的损害。
快速响应: SMF20CA 能够在微秒级别响应过电压事件,有效减小电压尖峰对后续电路的影响。
稳定性高: 尽管在高温和高湿环境下,SMF20CA 也能稳定工作,确保系统的可靠性。
小巧便捷: 其 SOD-123FL 封装使得在电子设计中占用极少空间,是高密度电子设备的不二选择。
良好的兼容性: SMF20CA 能与多种电路设计兼容,提供灵活的应用选项。
SMF20CA 是一款设计精良、性能卓越的保护元器件,适用于各类电子设备,尤其是在需要抗电压突变和过电压保护的场合。选择 SMF20CA 能够有效提升产品的可靠性,增强用户体验。同时,其小巧的封装设计为现代电子产品的紧凑性带来了极大的便利。对于寻求优化电路保护方案的工程师来说,SMF20CA 无疑是一个值得考虑的理想选项。

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.
