S-LBAS16HT1G 产品概述
一、产品简介
S-LBAS16HT1G 是乐山无线电（LRC）推出的一款车规级小功率二极管，采用 SC-76（SOD323）封装，适用于空间受限且要求可靠性的汽车电子与消费电子场合。器件具有高反向耐压与低反向漏电、快速恢复特性，适合作为保护、开关与整流用途的通用型器件。
二、主要参数
- 正向压降 Vf：1.25V @ IF = 150mA
- 直流反向耐压 Vr：75V
- 最大耗散功率 Pd：200mW
- 反向电流 Ir：1µA @ Vr = 75V
- 反向恢复时间 Trr：4ns（快速恢复）
- 工作结温范围 Tj：-55℃ ~ +150℃（车规级）
- 非重复峰值浪涌电流 Ifsm：5A（脉冲冲击能力）
- 封装：SC-76（SOD323）
三、特性与优势
- 车规温度等级：宽工作结温支持汽车级环境，与车载电子可靠性要求匹配。
- 高耐压、低漏电：75V 的反向耐压和 1µA 的反向电流适合高压侧保护与低泄漏要求场景。
- 快速恢复：4ns 的反向恢复时间适合高频开关与快速脉冲环境，减少反向恢复损耗与干扰。
- 小尺寸封装：SOD323 占板面积小，适合高密度 PCB 设计与便携设备。
注：器件标称连续工作电流为 200mA，但需结合 Pd 与 Vf 评估实际稳态电流。按 Pd = 200mW 与 Vf = 1.25V 估算，稳态最大电流约为 160mA；在 150mA 条件下的耗散约 187.5mW，接近器件耗散上限，实际设计应留有裕量并考虑散热。
四、典型应用
- 汽车电子：传感器保护、电源反接与跨接保护、车载模块输入保护。
- 开关电源与驱动电路：快速开关、续流路径、钳位与整流。
- 消费类电子：便携设备保护、指示灯/显示驱动回路、信号隔离保护。
- 一般用途：过压/反向保护、低功耗高耐压整流场合。
五、设计与封装注意事项
- 热管理：由于 Pd 仅 200mW，建议在 PCB 布局中采用较大焊盘或铜箔以提升散热，必要时增加散热铜皮或金属底座。
- 焊盘设计：遵循 SOD323/SC-76 推荐焊盘与回流工艺，确保良好焊接与可靠性。
- 浪涌与脉冲：Ifsm = 5A 提供短时间冲击能力，但需避免频繁大电流脉冲以防热失效。
- 电流裕度：长期工作电流应低于按 Pd 计算的稳态上限，留足安全裕量。
六、可靠性与选型建议
S-LBAS16HT1G 提供车规级温度范围与快速恢复特性，适合对体积与性能有综合要求的应用。在选型时，重点评估最大耗散功率、工作电流与 PCB 散热条件，必要时通过仿真或样品测试验证在目标环境下的热稳态与寿命。若需更高连续电流或更低 Vf，可考虑封装更大或不同结构的器件。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
