Product details

Overview

GBU607-K from Taiwan Semiconductor is a 6A, 1000V repetitive peak reverse voltage (V_RRM) standard bridge rectifier in GBU package, configured as a quad diode arrangement for full-wave AC-to-DC conversion. It delivers 175A non-repetitive surge current (I_FSM), operates up to 150°C junction temperature, and exhibits typical reverse leakage <5 µA at 25°C - used in high-reliability offline SMPS front-ends.

For engineers reviewing the GBU607-K datasheet, GBU607-K pinout, GBU607-K application, or GBU607-K equivalent, key selection criteria include V_RRM = 1000V, I_F = 6A, thermal resistance R_θJC = 2°C/W, and UL recognition (E-326243) for safety-critical power conversion designs.

Technical Context

The GBU607-K implements a monolithic quad-diode bridge configuration with common-cathode/common-anode topology, enabling single-package full-wave rectification without external interconnects. Its 1000V V_RRM rating supports universal-input (85–265V_AC) and high-line industrial AC inputs, while the 2°C/W junction-to-case thermal resistance enables direct heatsink mounting for sustained 6A conduction.

Electrical behavior is defined by low forward voltage drop (≤1.1V at 6A, 25°C), tight reverse leakage control (≤5 µA at 25°C, ≤500 µA at 125°C), and 211pF junction capacitance per diode (GBU604-K variant), reduced to 94pF for GBU605–GBU607-K - critical for EMI suppression in high-frequency SMPS.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - supports 700V RMS input; enables use in 400V DC bus and 3-phase rectifier auxiliary stages
I_F	6 A continuous average forward current - sustains 75W+ output in compact open-frame adapters
I_FSM	175 A (8.3ms half-sine) - withstands cold-start inrush into bulk capacitors without failure
R_θJC	2 °C/W - allows direct thermal interface to heatsink; enables >50% derating margin at 100°C case temp
I_R @ 25°C	<5 µA - minimizes standby power loss in energy-efficient no-load modes
UL File #	E-326243 - certified for primary-side isolation in Class II power supplies without additional creepage reinforcement

Pinout & Package

GBU607-K uses the industry-standard GBU molded plastic package (19.0 × 15.0 × 12.0 mm), with matte tin-plated leads compliant with J-STD-002 solderability and UL 94V-0 flammability rating. Polarity is marked on top surface.

Key Features

Feature	Design Value

Alternative Part	Technical Difference	Application Difference	Selection Advice
GBU6J (ON Semiconductor)	V_RRM = 1000V, I_F = 6A, but R_θJC = 3.5°C/W and no UL recognition	Lacks UL E-326243; higher thermal resistance requires larger heatsink area	Prefer GBU607-K where safety certification or thermal headroom is critical
KBU6K (Shindengen)	V_RRM = 1000V, I_F = 6A, I_FSM = 150A (vs. 175A), R_θJC = 2.5°C/W	Lower surge rating and slightly higher thermal resistance; different marking and date code format	Select GBU607-K when 175A surge immunity or minimal thermal resistance is required

Compared with GBU6J and KBU6K, the GBU607-K offers superior thermal performance (2°C/W), certified UL safety compliance, and highest surge robustness (175A), making it optimal for space-constrained, safety-critical, or high-inrush industrial power supplies.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for GBU607-K?

The GBU607-K has a maximum repetitive peak reverse voltage (V_RRM) of 1000 V, as confirmed in the Absolute Maximum Ratings table across all official Taiwan Semiconductor documentation versions (E2103). This rating defines its capability to block reverse voltage during each AC half-cycle without breakdown, making it suitable for 700V RMS input applications such as industrial 3-phase auxiliary supplies or universal-input SMPS.

Does GBU607-K have UL safety certification?

Yes, the GBU607-K is UL Recognized under File # E-326243, as explicitly stated in the FEATURES section of the official Taiwan Semiconductor datasheet. This certification applies to the entire GBU604-K through GBU607-K family and validates compliance with UL 60950-1/62368-1 for use in primary-side isolation circuits without additional creepage or clearance reinforcement.

What is the forward voltage drop (V_F) of GBU607-K at rated current?

The GBU607-K exhibits a maximum forward voltage drop (V_F) of 1.1 V at 6 A and 25°C, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss per diode pair in the bridge - critical for calculating total rectifier power dissipation in thermal design.

Can GBU607-K be mounted directly to a heatsink?

Yes, the GBU607-K supports direct heatsink mounting due to its low junction-to-case thermal resistance of 2°C/W and insulated GBU package construction. The datasheet specifies mounting torque ≤ 0.56 N·m and confirms the case meets UL 94V-0 flammability rating - enabling secure mechanical attachment and reliable thermal transfer without additional insulating hardware in most designs.

What is the junction capacitance (C_J) of GBU607-K?

The junction capacitance (C_J) of GBU607-K is 94 pF per diode at 1 MHz and 4.0 V reverse bias, as specified in the Electrical Specifications table for GBU605-K through GBU607-K variants. This lower capacitance versus GBU604-K (211 pF) reduces high-frequency noise coupling and improves EMI performance in fast-switching power converters.
