ER2G_R2_00001是PANJIT(强茂) 推出的2A/400V超快速恢复整流器,属于中功率整流器件,针对高频开关电路、高密度集成场景优化设计。核心特性可总结为5点:
参数设计直接决定器件的应用场景与可靠性,以下是核心参数的实际意义:
在额定连续电流(2A)下,正向压降仅1.7V,显著低于普通硅整流管(如1N4007在2A时Vf约1.9V以上)。该参数可直接降低整流过程中的导通损耗,提升电源转换效率——例如在12V/2A LED驱动中,每小时可减少约0.7Wh的功率损耗,长期使用更节能。
满足110V/220V交流输入的整流需求(交流峰值电压约155V/311V),留有约30%的安全余量,避免反向击穿风险,适配多数中压应用场景。
额定连续工作电流为2A,可稳定承载中等功率负载,适配5V/4A、12V/2A等常见电源输出规格的整流级,无需额外并联器件即可满足需求。
在额定反向电压下,漏电流仅150μA,可减少反向功率损耗,提升器件长期工作稳定性——尤其在高温(如125℃)环境下,漏电流仍保持低水平,降低发热风险。
具备较强的浪涌耐受能力,可应对开机瞬间、负载突变或电源波动带来的突发大电流(如适配器开机时的浪涌电流通常≤30A),减少器件损坏概率,提升系统可靠性。
覆盖工业级宽温要求,可在极端低温(如户外设备冬季-40℃)或高温(如电源内部密集散热区120℃)环境下稳定工作,无需额外降额设计。
采用SMB封装(DO-214AA标准),具备以下优势:
结合参数特性,ER2G_R2_00001主要应用于以下场景:
如手机、笔记本电脑、平板等便携设备的电源适配器,超快速恢复特性适配高频开关(50kHz~200kHz),减少开关损耗;2A电流与400V耐压满足多数消费级电源需求。
中功率LED照明(10~50W球泡灯、面板灯)的整流模块,低正向压降可降低电源损耗,提升LED发光效率;宽温范围适配户外照明(路灯、庭院灯)的环境变化。
PLC、变频器、伺服驱动器的辅助电源整流,宽温特性适配工业现场的温度波动(-20℃~85℃),高浪涌能力应对电机启动时的电流冲击。
车载充电器、仪表盘辅助电源,-55℃~150℃的宽温范围适配车辆启动时的低温(北方冬季-30℃)和运行时的高温(发动机舱附近100℃),满足车载环境的可靠性要求。
PANJIT(强茂)作为专业半导体制造商,ER2G_R2_00001符合RoHS环保标准(无铅无卤),并通过多项可靠性测试:
参数设计留有足够余量(如反向耐压400V高于220V交流峰值311V),可有效降低实际应用中的失效风险,适合对可靠性要求较高的商用与工业场景。
综上,ER2G_R2_00001凭借超快速恢复、低损耗、宽温耐受等特性,成为中功率整流场景的高性价比选择。
Request for quote
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.
