Product details
Overview
GBL410 from Diodes Incorporated is a 4A glass passivated single-phase bridge rectifier rated for 1,000V peak repetitive reverse voltage (VRRM), with 150A non-repetitive surge capability (IFSM) and low forward voltage drop of 1.0V at 2.0A per element - used in AC/DC front-end conversion for industrial power supplies and LED drivers.
For engineers reviewing the GBL410 datasheet, GBL410 pinout, GBL410 application, or GBL410 equivalent, key selection criteria include thermal resistance (RθJC = 4.2°C/W), reverse leakage (5 µA @ 25°C), RMS reverse voltage rating (700V), and UL 94V-0 molded plastic package suitability for high-reliability PCB mounting.
Technical Context
The GBL410 integrates four silicon diodes in a single-phase full-wave bridge configuration with glass passivated junctions to suppress surface leakage and enhance long-term stability under humid or contaminated environments. Its 1,000V VRRM rating supports universal-input (85–265VAC) designs without derating.
Thermal performance is defined relative to a 50×50×1.6mm copper heatsink (RθJA = 10°C/W), enabling 4.0A average forward current (I(AV)) operation; without heatsink, I(AV) drops to 2.4A due to RθJA increase. Junction-to-lead thermal resistance is 4.0°C/W, supporting direct PCB copper pour conduction paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1,000 V - Withstands peak reverse voltage up to 1 kV in AC line applications without breakdown. |
| I(AV) | 4.0 A - Maximum continuous DC output current with heatsink; enables compact 50–100W power supply designs. |
| IFSM | 150 A - Single half-sine surge rating (8.3ms) allows robust inrush handling during cold-start conditions. |
| VFM | 1.0 V @ 2.0A - Low forward drop per diode reduces conduction loss and improves efficiency vs. standard silicon bridges. |
| RθJC | 4.2 °C/W - Enables predictable junction temperature rise when mounted on copper heatsink for thermal design validation. |
| IR | 5 µA @ 25°C - Ultra-low reverse leakage ensures minimal standby power loss in offline SMPS standby circuits. |
Pinout & Package
GBL410 uses the GBL molded plastic package (UL 94V-0), measuring 20.5 × 10.9 × 3.5 mm (L × E × A), with matte tin-plated terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ~AC1 | AC Input Terminal 1 | One leg of AC input; connects to live or neutral depending on board layout orientation. |
| ~AC2 | AC Input Terminal 2 | Second AC input leg; forms full-wave bridge input pair with ~AC1. |
| +DC | Positive DC Output | Anode common point of two series-connected diodes; delivers rectified positive rail. |
| -DC | Negative DC Output | Cathode common point of two series-connected diodes; serves as return path for DC load. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU4K (ON Semiconductor) | Same 4A/1000V rating but higher VFM (1.1V) and RθJA (12°C/W); GBL410 offers 0.1V lower conduction loss. | Less efficient in thermally constrained layouts; requires larger heatsink area for same I(AV). | Prefer GBL410 where board space or thermal budget is limited. |
| KBU4M (Comchip) | Identical VRRM and IFSM, but higher IR (10 µA @ 25°C); GBL410 provides 2× lower leakage. | Slightly higher standby power in energy-sensitive applications like IoT gateways. | Choose GBL410 for ultra-low leakage-critical standby modes. |
Compared with GBU4K and KBU4M, the GBL410 delivers superior thermal resistance (4.2°C/W vs. ≥5.0°C/W), lower forward voltage (1.0V vs. ≥1.1V), and tighter reverse leakage (5 µA vs. ≥10 µA), making it optimal for space-constrained, high-efficiency AC/DC converters requiring long-term reliability.

FAQ
What is the maximum operating temperature for GBL410?
The GBL410 has a specified junction and storage temperature range of –55°C to +150°C. Its thermal resistance values (RθJC = 4.2°C/W, RθJA = 10°C/W) mean that at 4.0A I(AV) with heatsink, junction temperature remains within safe limits up to 60°C ambient - exceeding typical industrial requirements.
Can GBL410 be used without a heatsink?
Yes - the GBL410 supports 2.4A average forward current without a heatsink, based on its RθJA = 10°C/W rating and thermal derating curve. This makes it viable for low-power LED drivers or auxiliary supplies where board-level copper area replaces discrete heatsinks.
Is GBL410 compatible with lead-free reflow processes?
Yes - the GBL410 features matte tin-plated terminals qualified per MIL-STD-202 Method 208 and compliant with JEDEC J-STD-020 moisture sensitivity Level 1, supporting standard Pb-free reflow profiles up to 260°C peak temperature without delamination or solder joint defects.
How does GBL410's glass passivation improve reliability?
Glass passivation seals the silicon die surface against moisture ingress and ionic contamination, reducing surface leakage current and preventing premature breakdown under high humidity or pollution. This extends service life in outdoor or factory-floor environments where standard epoxy-passivated bridges may degrade.
