Product details

Overview

GBU806H from Taiwan Semiconductor is an AEC-Q101 qualified 8A, 800V standard bridge rectifier in GBU package, featuring 200A surge current capability, 1500VRMS dielectric strength, and typical reverse leakage <5µA at 25°C - used in automotive-grade AC/DC front-ends and industrial SMPS.

For engineers reviewing the GBU806H datasheet, GBU806H pinout, GBU806H application, or GBU806H equivalent, key selection factors include peak reverse voltage (800V), thermal resistance (R_θJC = 2°C/W), AEC-Q101 qualification status, and junction capacitance (94pF @1MHz).

Technical Context

This quad-configuration bridge rectifier integrates four silicon diodes in a single GBU molded package with matte tin-plated leads. It operates across -55°C to +150°C junction temperature range and supports 8.3ms non-repetitive surge currents up to 200A.

Electrical behavior is defined by forward voltage ≤1.1V at 8A/25°C, reverse current ≤500µA at 125°C, and junction-to-case thermal resistance of 2°C/W - enabling high-density PCB layouts with minimal heatsinking in space-constrained power supplies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	800 V - maximum repetitive reverse voltage the device blocks without breakdown
I_F	8 A - continuous average forward current rating at case temperature ≤75°C
I_FSM	200 A - peak non-repetitive surge current for 8.3ms half-sine wave
R_θJC	2 °C/W - thermal resistance from junction to case, critical for heatsink sizing
V_F @ 8A	≤1.1 V - forward voltage drop determining conduction loss and thermal load
I_R @ 125°C	≤500 µA - reverse leakage current affecting standby efficiency and thermal runaway risk
C_J	94 pF - junction capacitance per diode at 1MHz/4V, influencing EMI and switching noise

Pinout & Package

Package: GBU - molded plastic case with 4-pin inline configuration (AC1, AC2, +, –), UL 94V-0 rated, 4.00g weight, matte tin-plated solderable leads per J-STD-002.

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 8A/800V rating, but not AEC-Q101 qualified; R_θJC = 2.5°C/W	Suitable for commercial/industrial SMPS where automotive qualification is not required	Select GBU806H when AEC-Q101 compliance or lower thermal resistance is mandatory
ON Semiconductor GBPC806	8A/800V, AEC-Q101 qualified, but GBU package replaced by GBPC (4-pin DIP); R_θJC = 2.2°C/W	Requires PCB footprint change; higher profile may limit airflow in low-profile designs	Choose GBU806H for drop-in replacement in existing GBU-layout boards with tighter height constraints

Compared with GBU806H, GBU8K lacks automotive qualification and has higher thermal resistance, while GBPC806 requires mechanical redesign due to different package outline - making GBU806H optimal for AEC-Q101-compliant, space-constrained GBU-footprint upgrades.

FAQ

What is the peak repetitive reverse voltage rating of the GBU806H?

The GBU806H has a peak repetitive reverse voltage (V_RRM) rating of 800 V. This value is specified in the Absolute Maximum Ratings table and defines the maximum AC voltage the device can block during normal operation without entering avalanche breakdown. It corresponds to the "806" in the part number, where "6" indicates the 800V grade within the GBU801–GBU807 family.

Is the GBU806H suitable for automotive applications?

Yes, the GBU806H is AEC-Q101 qualified, as explicitly stated in the ordering information and features list. This qualification confirms it has passed stress tests for temperature cycling, humidity, mechanical shock, and high-temperature reverse bias - making it suitable for under-hood and powertrain-adjacent automotive systems such as on-board chargers and DC/DC converters.

What is the thermal resistance from junction to case for the GBU806H?

The junction-to-case thermal resistance (R_θJC) of the GBU806H is 2°C/W, as published in the Thermal Performance section. This low value enables efficient heat transfer to an external heatsink or metal-core PCB, supporting continuous 8A operation at elevated ambient temperatures when properly mounted.

How does the junction capacitance of the GBU806H compare to lower-voltage variants?

The GBU806H has a junction capacitance (C_J) of 94 pF per diode at 1 MHz and 4.0 V reverse bias, as confirmed in the Electrical Specifications table. This is significantly lower than GBU801–GBU804 (211 pF), reflecting optimized doping profiles for higher-voltage operation and reduced high-frequency switching noise.

What packaging and marking format does the GBU806H use?

The GBU806H is supplied in the GBU package with 20 units per tube. Its marking includes "GBU806" followed by "G" (green compound), date code (YWW), and factory code (F), as shown in the Marking Diagram. The leads are matte tin-plated and compliant with J-STD-002 for reliable solderability.
