Product details

Overview

GBL04H from Taiwan Semiconductor is a 4A, 400V AEC-Q101 qualified standard bridge rectifier in GBL package, featuring glass passivated junctions, <1.1V forward voltage at 4A/25°C, <5µA reverse current at 25°C, and 150A surge rating. It serves as the AC-to-DC input stage in automotive-grade power supplies.

For engineers reviewing the GBL04H datasheet, GBL04H pinout, GBL04H application, or GBL04H equivalent, key selection criteria include peak reverse voltage (400V), thermal resistance (R_θJL = 13°C/W), AEC-Q101 qualification status, and UL recognition (E-326243).

Technical Context

This quad-diode bridge integrates four silicon junctions in a single GBL molded package with matte tin-plated leads. Its glass passivation ensures stable reverse leakage (<5 µA @ 25°C) and high dielectric strength, supporting reliable operation in harsh ambient conditions up to 150°C junction temperature.

The device delivers 4A average forward current at TC = 50°C and withstands 150A non-repetitive surge (8.3ms half-sine). Thermal performance is defined by R_θJC = 8°C/W and R_θJA = 32°C/W, enabling PCB-mount designs with minimal heatsinking for SMPS front-end rectification.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - Maximum repetitive reverse voltage per diode; defines safe AC input voltage range (e.g., 280 V_RMS mains).
I_F	4 A - Continuous forward current at case temperature 50°C; supports compact 2"x3" heatsink or copper-pad PCB mounting.
I_FSM	150 A - Peak surge current handling for 8.3 ms; enables robust startup and line-transient immunity in offline converters.
V_F	1.1 V max @ 4A/25°C - Low conduction loss per diode; reduces total bridge dissipation to ≤4.4 W at full load.
I_R	5 µA max @ 25°C - Ultra-low reverse leakage; critical for low-power standby and high-impedance bias networks.
R_θJL	13 °C/W - Junction-to-lead thermal resistance; allows direct thermal coupling to PCB copper for efficient heat extraction.
T_J max	150 °C - Maximum operating junction temperature; supports under-hood automotive environments without derating.

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/400V rating but TO-220AC package; higher R_θJA (40°C/W); no AEC-Q101 qualification.	Preferred for cost-sensitive consumer power supplies where automotive qualification is unnecessary.	Select GBU4K only when AEC-Q101 is not required and TO-220 mounting is acceptable.
DF04M (Vishay)	4A/400V, GBL-compatible footprint; RoHS/halogen-free; AEC-Q101 qualified; slightly higher V_F (1.15 V max @ 4A).	Drop-in replacement in existing GBL layouts; validated for same automotive and industrial use cases.	DF04M offers identical mechanical fit and qualification-ideal for dual-sourcing where Taiwan Semiconductor supply is constrained.

Compared with GBL04H, GBU4K lacks automotive qualification and has inferior thermal resistance, while DF04M matches its AEC-Q101 status and GBL footprint but trades marginal forward voltage increase for second-source assurance.

FAQ

What is the peak repetitive reverse voltage rating for GBL04H?

The GBL04H has a peak repetitive reverse voltage (V_RRM) of 400 V, as confirmed in the Absolute Maximum Ratings table of Taiwan Semiconductor's K2103 datasheet. This rating applies per diode within the bridge and determines the maximum AC input voltage it can safely rectify-e.g., up to 280 V_RMS sine wave. Exceeding this value risks avalanche breakdown and permanent damage to the GBL04H.

Is GBL04H qualified to AEC-Q101, and what does that mean for automotive use?

Yes, GBL04H is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and confirmed in the FEATURES section of the datasheet. This qualification validates the GBL04H for use in automotive power electronics-including engine control units, body control modules, and onboard chargers-under extended temperature, vibration, and lifetime reliability requirements beyond commercial-grade components.

What is the forward voltage drop of GBL04H at rated current?

The GBL04H exhibits a maximum forward voltage (V_F) of 1.1 V per diode at 4 A and 25°C junction temperature, per the Electrical Specifications table. Since a bridge rectifier conducts through two diodes in series during each half-cycle, the total conduction drop is ≤2.2 V, directly impacting conduction loss and thermal design in the GBL04H-based power stage.

Does GBL04H have UL recognition, and what is the file number?

Yes, GBL04H is UL Recognized under File # E-326243, as stated in the FEATURES section of the official datasheet. This certification confirms compliance with UL 60950-1 and UL 62368-1 for use in power supplies requiring reinforced insulation, enabling simplified safety approvals for end equipment using the GBL04H in primary-side rectification.

What package type and lead finish does GBL04H use?

GBL04H uses the GBL molded plastic package with matte tin-plated leads, verified in the MECHANICAL DATA and ORDERING INFORMATION sections. The leads meet J-STD-002 solderability requirements and JESD 201 Class 2 whisker resistance, ensuring reliable reflow soldering and long-term interconnect integrity in both industrial and automotive PCB assemblies containing the GBL04H.
