Diodes Incorporated KBP206G

Overview

KBP206G from Diodes Incorporated is a 2.0A standard recovery bridge rectifier with 600V peak repetitive reverse voltage (VRRM), 1.1V forward voltage drop at 2A, and 5µA maximum reverse leakage current at 25°C. It features glass-passivated die construction, 1,500 VRMS case dielectric strength, and is rated for 65A non-repetitive surge current - used in AC/DC front-end conversion for industrial power supplies and LED drivers.

For engineers reviewing the KBP206G datasheet, KBP206G pinout, KBP206G application, or KBP206G equivalent, key selection criteria include VRRM margin for line-voltage transients, thermal resistance (RθJC = 14°C/W), surge rating for inrush handling, and UL recognition (E95060) for safety-compliant designs.

Technical Context

This single-phase, full-wave bridge rectifier integrates four silicon diodes in a molded KBP package with tin-plated leads. It operates under resistive or inductive loads at 60Hz, with derating required for capacitive loads (−20% IO). The device is characterized for junction temperatures from −55°C to +150°C and exhibits 25pF typical junction capacitance per element at 4V/1MHz.

Thermal performance is defined with mounting on a 75mm × 75mm × 1.6mm copper heatsink: RθJC = 14°C/W (junction-to-case), RθJL = 18°C/W (junction-to-lead), and RθJA = 40°C/W (junction-to-ambient). Reverse breakdown voltage is guaranteed at 600V minimum with 5µA test current.

FAQ

What is the maximum operating temperature for KBP206G?

KBP206G has a specified operating junction temperature range of −55°C to +150°C. Its thermal resistance values (RθJC = 14°C/W, RθJA = 40°C/W) allow it to sustain 2.0A average current at TC = +105°C when properly heatsinked. Ambient operation beyond +75°C requires derating per the forward current curve in Figure 1 of DS21205.

Is KBP206G suitable for use in automotive applications?

KBP206G is not AEC-Q200 qualified and is not recommended for automotive under-hood or safety-critical systems. While Diodes offers AEC-Q200-qualified alternatives in the KBP family (e.g., KBP206G-A), this standard version lacks PPAP documentation, extended temperature validation, and IATF 16949-controlled manufacturing traceability required for automotive deployment.

How does the KBP package differ from KBPC or GBU packages?

The KBP package is a 4-pin single-in-line (SIP) molded plastic housing measuring 14.5mm × 10.4mm × 4.0mm, distinct from KBPC (larger, 4-pin, rectangular base) and GBU (smaller, 4-pin, rounded body). KBP uses straight leads optimized for through-hole PCB mounting and manual rework, whereas KBPC supports higher current (3.0A+) and GBU targets compactness over thermal mass.

Can KBP206G replace KBP204G in an existing design?

Yes - KBP206G is a direct upgrade from KBP204G (400V VRRM) with identical pinout, package, and thermal characteristics, offering increased reverse voltage margin (600V vs. 400V) without layout changes. Conduction loss (VF = 1.1V) and surge rating (65A) remain unchanged, making it suitable for designs needing enhanced transient immunity on 230VAC lines.
