Product Description
This DB bridge rectifier series is for compact boards that need full-wave rectification at low current. You can compare DB101, DB105, DB107, DB207 and DB310 for meters, small adapters and auxiliary AC/DC circuits. The value is a small through-hole footprint that fits close to transformers or AC input pins. Lian Tuo helps you check average current, voltage class, body height, pin spacing and replacement markings before sampling, so your small bridge rectifier does not become the weak point in a tight board layout. It also helps purchasing avoid weak equivalent choices.
Our DB Bridge Rectifier Options
| DB101 Bridge Rectifier | Low-voltage DB option for small auxiliary rectifier paths. Best fit for meter power inputs when board space is tight. |
| DB105 Bridge Rectifier | Common DB package for compact general AC input boards. Fits small adapter boards where heat margin needs an early check. |
| DB107 Bridge Rectifier | 1000V small bridge for adapters and control circuits. Useful in auxiliary AC/DC circuits if replacement approval must stay simple. |
| DB207 Bridge Rectifier | Higher-current DB family part for small power modules. Choose it for meter power inputs when assembly routing cannot change late. |
| DB310 Bridge Rectifier | 3A bridge choice for slightly stronger compact boards. Helps small adapter boards when repeat purchasing needs clearer stock choices. |

Respect Current Limits
A DB bridge rectifier is small, so current and heat should be checked carefully. Voltage rating alone does not prove the package is safe. You can reduce risk by comparing average current, capacitor charging and board temperature before choosing a DB101, DB107 or DB310 style part. It also helps purchasing avoid weak equivalent choices.
Keep Layout Tight
DB packages are useful when the bridge must sit near a transformer, connector or small fuse. The compact body helps your layout stay simple. Before sample approval, confirm pin spacing and body height so the replacement does not crowd nearby components. That keeps the RFQ tied to the real board condition.
Support Auxiliary Rails
Small auxiliary rails often need a dependable bridge rectifier without high power cost. The DB bridge rectifier series gives you a practical option for meters, control boards and low-current adapter circuits. Lian Tuo can help you compare voltage bins and available models. This makes repeat orders easier to check internally.
Avoid Wrong Upgrades
A larger bridge may not be the best upgrade for a DB package. If the PCB is fixed, changing package size can slow approval or require layout work. It is better to choose the correct DB rating and confirm heat margin first. It also protects the layout from late package changes.
Vertical Product Applications
Meter Power Inputs
Use a DB bridge rectifier in meter power inputs when the current is low and PCB space is limited. The small body keeps the AC input simple. You can check voltage rating and temperature rise before approving the bridge for repeated meter production. This makes repeat orders easier to check internally.
Small Adapter Boards
Small adapter boards often need a compact bridge near the transformer or AC pins. A DB bridge rectifier gives enough rectification for light-load designs. Confirm capacitor size and enclosure heat so the bridge does not run beyond its safe current. It also protects the layout from late package changes. This gives your sample review more evidence before approval.
Auxiliary AC/DC Circuits
Auxiliary AC/DC circuits inside appliances or controls can use DB bridge rectifiers to create low-current DC rails. The package is easy to place and replace. You can share the board photo and target current for a focused equivalent recommendation. This gives your sample review more evidence before approval. It also helps purchasing avoid weak equivalent choices.
FAQ
When should I use a DB bridge rectifier?
Use a DB bridge rectifier for low-current full-wave rectification where PCB space is tight. It is common in meters, small adapters and auxiliary AC/DC circuits. Always check average current and temperature, not only voltage rating. That keeps the RFQ tied to the real board condition.
Can DB107 replace other DB bridge parts?
It can replace some DB parts if the voltage, current and package match your board. You should still confirm pin spacing, body height and thermal condition before using DB107 as a direct substitute. This makes repeat orders easier to check internally.
Why is current rating critical for DB bridges?
DB bridge packages are compact, so heat can rise quickly if the load current is too high. A high voltage rating does not solve current or thermal stress. Check the real load and capacitor charging before approval. It also protects the layout from late package changes.
What information helps quote DB bridge rectifiers?
Send the old model, current, voltage, package size, application and quantity. A board photo helps confirm whether the layout needs a DB, DBS or another small bridge package. This gives your sample review more evidence before approval. It also helps purchasing avoid weak equivalent choices.
Can I replace DB with GBU bridge rectifiers?
Only if the board has space for the larger package and different pin arrangement. GBU bridges provide more current, but they are usually not drop-in replacements for compact DB layouts. It also helps purchasing avoid weak equivalent choices. That keeps the RFQ tied to the real board condition.
Does Lian Tuo support DB bridge equivalents?
Yes. We can compare DB101, DB105, DB107, DB207 and DB310 style options with your old part. We check rating and package details before suggesting a replacement. That keeps the RFQ tied to the real board condition. This makes repeat orders easier to check internally.
