Product details
Overview
GBLA06 from Taiwan Semiconductor is a 4A, 600V repetitive peak reverse voltage (VRRM) standard bridge rectifier in GBL package, featuring glass-passivated junctions, UL recognition (E-326243), and AEC-Q101 qualification option. It delivers 120A surge current (IFSM), 10°C/W junction-to-lead thermal resistance, and typical reverse leakage <5µA at 25°C - used in compact AC/DC front-ends for LED drivers and industrial adapters.
For engineers reviewing the GBLA06 datasheet, GBLA06 pinout, GBLA06 application, or GBLA06 equivalent, key selection criteria include VRRM=600V, IF=4A at TC=50°C, TJ max=150°C, RθJL=10°C/W, and GBL package compatibility with PCB-mount thermal pads per JESD201 Class 2 whisker testing.
Technical Context
The GBLA06 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 reverse characteristics up to 125°C, where IR remains ≤500µA under rated VR.
Thermally optimized for PCB mounting on 0.5"x0.5" copper pads or heatsinked 2"x3"x0.25" aluminum plates, it supports continuous conduction mode operation with I²t rating of 59A²s for 8.3ms surges and meets UL 94V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum non-repetitive reverse voltage the device blocks without breakdown; defines minimum input AC peak voltage support (e.g., 420V RMS) |
| IF (TC = 50°C) | 4 A - average forward current sustainable at case temperature 50°C; requires thermal management via PCB copper or heatsink |
| IFSM (8.3ms) | 120 A - peak surge current capability; enables robust startup handling in SMPS with high inrush |
| RθJL | 10 °C/W - junction-to-lead thermal resistance; enables direct thermal path to PCB copper pads for efficient heat dissipation |
| IR (TJ = 25°C) | <5 µA - low reverse leakage per diode; preserves efficiency in high-impedance bias networks and standby modes |
| CJ (1MHz, VR = 4V) | 40 pF - junction capacitance for GBLA06–GBLA10 variants; impacts EMI filtering design and high-frequency switching losses |
Pinout & Package
GBLA06 uses the GBL molded plastic package (UL 94V-0), with matte tin-plated leads solderable per J-STD-002 and polarity marked on top surface. Dimensions conform to standard GBL outline per Taiwan Semiconductor datasheet Rev E2103.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ~AC1 | AC input terminal 1 | One leg of AC input; connects to line or neutral side of transformer secondary or bridge input |
| ~AC2 | AC input terminal 2 | Second leg of AC input; completes full-wave rectification path with ~AC1 |
| +DC | Positive DC output | Common cathode node; supplies filtered positive rail to downstream capacitors and regulators |
| -DC | Negative DC output / return | Common anode node; serves as circuit ground reference for rectified output |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6K (ON Semiconductor) | Same 600V VRRM, 6A IF rating, but larger GBU package (RθJA=35°C/W vs GBLA06's 47°C/W); no AEC-Q101 option | Higher current headroom but requires more PCB area; less suitable for ultra-compact designs | Select GBU6K only when >4A continuous current or lower ambient thermal resistance is required |
| DF006S (Diodes Inc.) | 600V VRRM, 1A IF rating, smaller DF-S package; CJ=35pF, RθJL=15°C/W; RoHS/halogen-free compliant | Limited to low-power applications (<10W); not rated for 4A continuous operation | Choose DF006S only for space-constrained, low-current auxiliary rails - not a functional replacement for GBLA06's 4A capability |
Compared with GBU6K and DF006S, the GBLA06 uniquely balances 4A current capacity, compact GBL footprint, 10°C/W thermal performance, and AEC-Q101 availability - making it optimal for mid-power industrial and automotive-qualified AC/DC converters where board space and reliability are jointly constrained.

FAQ
What is the maximum junction temperature rating for GBLA06?
The GBLA06 has a maximum junction temperature (TJ) rating of +150°C, with storage temperature range from –55°C to +150°C. This allows reliable operation in high-ambient environments such as enclosed LED drivers or industrial enclosures, provided thermal design maintains actual TJ below this limit using the specified 10°C/W junction-to-lead resistance and appropriate PCB copper area.
Does GBLA06 have AEC-Q101 qualification?
Yes - the GBLA06H variant is AEC-Q101 qualified, while the base GBLA06 is not. The "H" suffix denotes full automotive-grade stress testing including temperature cycling, high-temperature reverse bias (HTRB), and unbiased highly accelerated stress test (UHAST). For automotive applications, specify GBLA06H to ensure compliance.
What is the forward voltage drop of GBLA06 at rated current?
The GBLA06 exhibits a maximum forward voltage (VF) of 1.0 V per diode at IF = 4 A and TJ = 25°C, measured under pulsed conditions (PW = 0.3 ms). At elevated temperatures or continuous DC operation, VF may rise slightly due to positive temperature coefficient, but remains within design margins for typical 4A applications.
How does the junction capacitance of GBLA06 affect EMI performance?
The GBLA06 has a typical junction capacitance (CJ) of 40 pF per diode at 1 MHz and VR = 4.0 V. This value influences high-frequency noise generation during commutation; lower CJ (vs. earlier GBLA005–04 variants at 95 pF) reduces capacitive coupling into control circuits, easing EMI filter design in 65–100 kHz SMPS applications.
What packaging and marking details apply to GBLA06?
The GBLA06 is supplied in GBL package with matte tin-plated leads, packed 25 units per tube. Marking includes "GBLA06" as the code, "G" for green compound, YWW date code, and factory identifier "F". Polarity is indicated by a cathode bar adjacent to the +DC terminal on the top surface.
