Keep Low Voltage Lines Stable
A low voltage rectifier diode helps you protect compact AC/DC input stages from unstable polarity and reverse current stress. With 50V, 100V and 200V ratings, you can select a device that fits the real operating voltage of your board. This keeps your circuit dependable while helping you avoid paying for unnecessary high-voltage parts.
Reduce Sourcing Work
When you need several current ratings in one order, this low voltage rectifier diode range helps simplify sourcing. You can match 1A, 2A, 3A and higher-current designs under one supplier, with axial and SMD package choices. Lian Tuo supports datasheet checks, replacement model suggestions, sample requests and export packing for bulk orders.
Applications
Adapters And Chargers
For adapters and chargers, a low voltage rectifier diode gives you stable rectification in compact power input and DC output stages. You can choose 50V to 200V ratings for low-voltage designs, then match the current rating to your load. This helps you control cost while keeping everyday charging products reliable.
LED Driver Boards
In LED driver boards, the low voltage rectifier diode supports consistent current direction and dependable power conversion. Low leakage and practical package options help you manage heat and board space. If your project uses automated placement, SMD parts such as S1A to S1D help you keep assembly efficient.
Appliance Control Boards
Appliance control boards often need stable rectification in limited PCB space. This low voltage rectifier diode range gives you axial and SMD choices for relay drives, auxiliary power inputs and control circuits. You can source common series in bulk and keep replacement models aligned across multiple appliance programs.

FAQ
Q1: What is a low voltage rectifier diode used for?
A low voltage rectifier diode is used to convert AC to DC or control one-way current flow in lower-voltage circuits. You will commonly use it in adapters, chargers, LED drivers, appliance control boards and compact DC power input stages where 50V to 200V reverse-voltage ratings are enough.
Q2: How do I choose between 50V, 100V and 200V ratings?
Choose a rating above the maximum reverse voltage your circuit can see, including transient margin. If your board runs at very low DC voltage, 50V or 100V may be enough. If your input has wider fluctuation, a 200V low voltage rectifier diode gives you a safer margin.
Q3: Which package should I select for my PCB?
For through-hole assembly, DO-41, DO-15 and DO-201AD packages are common choices. For automated SMT production, SMA, SMB and SMC packages can save space and labor. You can send your current, voltage, board size and assembly method, and we will help you match the package.
Q4: Can you supply OEM marking and packing?
Yes. Lian Tuo can discuss OEM marking, tape packaging, bulk packing and export carton requirements according to your order quantity. You can also request model cross-reference support when replacing existing low voltage rectifier diode parts from another supplier.
Q5: What information should I send for a quotation?
Please send the part number, target voltage, current rating, package, quantity, delivery country and any packing requirement. If you do not have a fixed model, share the application and electrical limits so we can suggest a suitable low voltage rectifier diode series.
