Bridgold DB107 Glass Passivated Bridge Rectifier 1000V 1A
The Bridgold DB107 is a single-phase, four-pin bridge rectifier designed for PCBs. It delivers a peak inverse voltage of up to 1000 V and a forward current around 1 A, making it suitable for compact power supplies and conversion stages. The glass-passivated construction reduces leakage and improves reliability under varying temperatures, with features oriented toward low reverse leakage and solid surge handling for modest load profiles.
FMHXG DB107 Inline Rectifier Bridge Stack 1000V 1A
This inline rectifier stack provides the DB107 family with a 1000 V maximum reverse voltage and 1 A forward current. It is described as a four-pin, glass-passivated bridge suitable for printed circuit boards. Its specifications emphasize predictable operation across a wide temperature range (-55 to +150 degrees Celsius) and low leakage, making it a pragmatic choice for compact, low-noise DC power sections.
Bridgold KBJ3510 Glass Passivated Bridge Rectifier
The KBJ3510 offers high-current handling in a 4-pin package, with a robust 35A surge rating and 1000V blocking voltage. Its glass-passivated construction minimizes leakage and improves reliability for induction cookers and other high-demand rectifier applications. The device is positioned as a cost-efficient, PCB-friendly option for moderate-to-high current rails in compact designs.
GBJ5010 50A 1000V Bridge Rectifier Diode
The GBJ5010 by HUABAN is a high-current, 1000V bridge rectifier in a glass-passivated design. It targets applications requiring more substantial current handling in single-phase circuits, with RoHS compliance emphasized. The part is well-suited for power adapters and other positive rail rectification tasks where reliability is essential across broader operating conditions.
TL400G-T2-B Bridge Rectifier – 4A 50V
The TL400G-T2-B from TAITRON COMPONENTS INC is a glass-passivated bridge rectifier rated at 4 A and 50 V, packaged in the TL form factor. This device is notable for small-footprint applications such as low-voltage power supplies and compact devices where a robust, glass-passivated rectifier is required. Its straightforward performance makes it a reliable choice for hobbyist and professional circuits alike.
Buying Guide: Key Purchase Considerations
When choosing a glass passivated bridge rectifier, consider the following factors to ensure alignment with your design goals:
- Voltage rating: Match the maximum repetitive peak reverse voltage (VRRM) to your supply and any potential transients. Higher VRRM provides margin in surge-rich environments but may increase package size.
- Current rating: Select a device whose forward current (IF) and surge current (IS) accommodate peak load plus startup spikes. Over-specing can improve reliability but may impact cost and form factor.
- Package and mounting: Decide between compact four-pin bridge packages for tight PCB layouts and larger, higher-current formats for rugged environments. Consider heat dissipation requirements and mounting style.
- Leakage and recovery: Glass-passivated designs typically offer low leakage and stable performance over temperature. Evaluate leakage specs in your DC bus design to minimize noise.
- Temperature range: Some parts specify broad operating temperatures (e.g., -55 to +150 C). Applications in industrial or outdoor settings benefit from wider ranges.
- RoHS compliance and materials: Ensure the part meets RoHS requirements if you’re designing for consumer electronics or medical devices subject to regulatory standards.
- PCB compatibility: Look at lead spacing and pin configuration to match existing footprints and assembly processes.
- Cost vs. performance: Higher current and voltage capabilities typically increase cost. Balance performance needs with budget constraints for the project at hand.
In summary, select a bridge rectifier that provides a suitable voltage and current margin, reliable performance under your operating conditions, and a package that fits your PCB layout and assembly method. For hobbyist projects, smaller four-pin glass-passivated rectifiers are convenient, while industrial designs may demand higher current variants like the KBJ3510 or GBJ5010.
