Product details
Overview
GBL08 from Taiwan Semiconductor is a 4A, 800V repetitive peak reverse voltage (VRRM) standard bridge rectifier in GBL package, featuring glass-passivated junctions, <1.1V forward voltage at 4A/25°C, <500µA reverse current at 125°C, and UL Recognized File # E-326243 - used in AC/DC front-end stages of industrial SMPS and lighting ballasts.
For engineers reviewing the GBL08 datasheet, GBL08 pinout, GBL08 application, or GBL08 equivalent, key selection criteria include VRRM=800V, IF=4A at TC=50°C, IFSM=150A surge rating, RθJC=8°C/W thermal resistance, and AEC-Q101 qualification availability (GBL08H variant).
Technical Context
The GBL08 integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode and common-anode terminals. Its glass-passivated junction ensures stable leakage performance up to 125°C and supports high-reliability operation in thermally constrained PCB layouts.
Thermal design is enabled by low junction-to-case resistance (RθJC = 8°C/W) and defined mounting options: direct PCB pads (0.5"×0.5" copper) or heatsink (2"×3"×0.25" Al-plate). Junction capacitance is 40pF per diode at 1MHz/4V, supporting moderate-frequency switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - maximum non-repetitive reverse voltage the bridge withstands without breakdown |
| IF (TC = 50°C) | 4 A - continuous forward current rating with heatsink at 50°C case temperature |
| IFSM (8.3ms) | 150 A - surge capability for line-start transients and inrush limiting |
| VF (IF = 4A, TJ = 25°C) | ≤1.1 V - total forward drop across two series diodes in conduction path |
| IR (TJ = 125°C) | ≤500 µA - total reverse leakage across all four diodes at elevated junction temperature |
| RθJC | 8 °C/W - enables thermal interface design using standard heatsink mounting or copper pad layout |
| CJ (per diode) | 40 pF - limits high-frequency noise coupling and affects EMI filter sizing |
Pinout & Package
GBL08 uses the GBL molded plastic package (UL 94V-0 rated), 15.7mm × 11.2mm × 4.2mm, with matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker testing.

Applications
| Industrial SMPS Front-End | LED Driver Power Stage |
|---|---|
Use Scenario: AC mains rectification in 50–200W off-line switch-mode power supplies for PLCs and motor drives. IC Role / Device Role / Timing Role: Primary bridge rectifier converting 85–265VAC input to unregulated DC bus prior to PFC and DC/DC conversion. Use Value: 800V VRRM provides 2× safety margin over 400VDC peak from 230VAC input, reducing risk of catastrophic failure during line surges. | Use Scenario: Rectifying AC input in constant-current LED drivers for streetlights and high-bay fixtures. IC Role / Device Role / Timing Role: Full-wave bridge delivering ripple-suppressed DC to buck or flyback controller ICs driving high-power LED strings. Use Value: Low VF (≤1.1V) minimizes conduction loss at 4A, improving driver efficiency and reducing thermal load on aluminum PCBs. |
| Universal Input Adapters | Automotive Lighting Modules |
Use Scenario: Dual-voltage (100–240VAC) AC/DC adapters for consumer and medical peripherals. IC Role / Device Role / Timing Role: Input-stage rectifier enabling wide-input-range operation with minimal derating across global mains voltages. Use Value: 150A IFSM handles cold-start inrush into bulk capacitors, preventing fuse blow and ensuring robust startup behavior. | Use Scenario: On-board AC rectification in headlamp or fog lamp modules powered from vehicle 12V/24V systems with external AC sources (e.g., service tools). IC Role / Device Role / Timing Role: Bridge rectifier in auxiliary power supplies meeting AEC-Q101 requirements when specified as GBL08H variant. Use Value: AEC-Q101 qualification ensures survivability under automotive temperature cycling (-40°C to +125°C ambient) and mechanical vibration profiles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBU8K | Same 800V VRRM, 4A IF, but TO-220AC package; RθJC = 5°C/W, higher thermal performance but larger footprint | Preferred where heatsinking is critical and board space allows TO-220 mounting | Select GBU8K if thermal budget is tighter and PCB real estate permits larger through-hole package |
| ON Semiconductor GBPC1208 | 800V VRRM, 12A IF rating, GBPC package (larger); higher current capacity but higher VF (~1.2V @ 4A) | Suitable for future-proofing or parallel designs requiring headroom beyond 4A | Choose GBPC1208 only when system-level current demand exceeds 4A or dual-device redundancy is required |
Compared with GBL08, GBU8K offers superior thermal resistance but requires TO-220 layout changes and lacks AEC-Q101 option; GBPC1208 delivers higher current headroom at cost of increased conduction loss and board area - GBL08 remains optimal for space-constrained, cost-sensitive 4A industrial and lighting rectification.

FAQ
What is the maximum junction temperature rating for GBL08?
The GBL08 has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments such as enclosed LED drivers or industrial enclosures. Derating curves confirm usable current down to 0A at 150°C case temperature. Thermal design must respect RθJC = 8°C/W to avoid exceeding this limit under 4A load.
Does GBL08 support AEC-Q101 qualification?
Yes - the GBL08H variant is AEC-Q101 qualified, while standard GBL08 is not. The "H" suffix denotes automotive-grade stress testing including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. For automotive lighting or body control modules, specify GBL08H; GBL08 remains suitable for industrial and commercial applications.
What is the forward voltage drop of GBL08 at full rated current?
The GBL08 exhibits a maximum forward voltage (VF) of 1.1 V per diode at IF = 4 A and TJ = 25°C. Since a full-wave bridge conducts through two diodes in series, the total forward drop is ≤2.2 V. At elevated temperatures (125°C), VF decreases slightly, but conduction losses remain predictable for thermal modeling using the published derating curve.
How does GBL08 compare to GBL06 in terms of reverse voltage rating?
The GBL08 is rated for 800 V repetitive peak reverse voltage (VRRM), whereas GBL06 is rated for 600 V. Both share identical IF = 4 A, IFSM = 150 A, and thermal characteristics. Select GBL08 when designing for 230VAC-derived DC buses with >2× safety margin or for regions with high line-voltage transients - GBL06 suffices for 115VAC or well-regulated 230VAC inputs.
What packaging and reel options are available for GBL08?
GBL08 is supplied in tube packaging: 25 units per tube. Tape-and-reel is not offered for the GBL package. Lead finish is matte tin per J-STD-002, and devices meet JESD201 Class 2 whisker resistance. Date code and factory marking follow standard GBL outline: "GBL08", "G", YYWW, and factory code "F".
