Taiwan Semiconductor Corporation KBL607G

Overview

KBL607G from Taiwan Semiconductor is a 6A, 1000V repetitive peak reverse voltage (V_RRM) standard quad-bridge rectifier in KBL package, featuring glass-passivated junctions and UL Recognized construction (File #E-326243), designed for high-reliability AC/DC conversion in off-line power supplies.

For engineers reviewing the KBL607G datasheet, KBL607G pinout, KBL607G application, or KBL607G equivalent, key selection criteria include V_RRM = 1000V, I_F = 6A, I_FSM = 175A, R_θJL = 7.5°C/W, and RoHS-compliant matte tin-plated leads suitable for J-STD-002 soldering.

Technical Context

The KBL607G integrates four silicon diodes in a single-phase bridge configuration with common-cathode and common-anode terminals, enabling full-wave rectification without external interconnection. Its glass-passivated junction ensures stable reverse leakage (<500 µA at 125°C) and robust surge tolerance (I²t = 127 A²s).

Thermally optimized for PCB mounting, it delivers 6A average forward current with 1.1V max forward voltage at 6A/25°C and operates across –55°C to +150°C junction temperature range, supported by UL 94V-0 molding compound and JESD201 Class 1A whisker resistance.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) of the KBL607G?

The KBL607G has a V_RRM rating of 1000 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version H2308). This value is specific to the KBL607G variant and distinguishes it from lower-voltage members of the KBL60xG family such as KBL601G (50 V) or KBL605G (600 V). The KBL607G must be used where sustained reverse voltage exceeds 700 V.

Does the KBL607G meet RoHS and UL requirements?

Yes, the KBL607G is RoHS compliant and UL Recognized under File #E-326243, as stated in the FEATURES section of the Taiwan Semiconductor datasheet. The UL recognition applies to the entire KBL601G–KBL607G series and covers flammability (UL 94V-0), terminal plating, and construction integrity-enabling direct use in certified end equipment without additional system-level safety testing.

What is the forward voltage (V_F) of the KBL607G at full rated current?

The KBL607G exhibits a maximum forward voltage of 1.1 V at I_F = 6 A and T_J = 25°C, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss at full load. At elevated junction temperatures, V_F decreases slightly, but thermal design must account for this 1.1 V drop to calculate power dissipation and temperature rise.

Can the KBL607G replace KBL605G or KBL606G in an existing design?

Yes, the KBL607G is a direct drop-in replacement for KBL605G (600 V) and KBL606G (800 V) because all share identical KBL package dimensions, pinout, thermal characteristics, and electrical parameters except V_RRM. No PCB or schematic changes are needed. Using KBL607G increases reverse voltage margin without affecting layout, thermal performance, or bill-of-materials cost in most applications.

What is the junction-to-lead thermal resistance (R_θJL) of the KBL607G?

The KBL607G has a typical junction-to-lead thermal resistance of 7.5°C/W, as specified in the Thermal Performance section of the datasheet. This parameter is critical for estimating junction temperature rise when mounted on a PCB without a heatsink. It assumes proper soldering of all four leads to adequate copper area and is independent of ambient conditions-enabling accurate thermal modeling in natural-convection environments.
