Taiwan Semiconductor Corporation GBPC1506

Overview

GBPC1506 from Taiwan Semiconductor is a 15A, 600V standard single-phase bridge rectifier in GBPC package with quad diode configuration, glass-passivated junctions, and integrally molded heatsink; delivers ≤1.1V forward voltage at 7.5A and <5µA reverse leakage at rated voltage, used in AC-DC conversion stages of industrial power supplies.

For engineers reviewing the GBPC1506 datasheet, GBPC1506 pinout, GBPC1506 application, or GBPC1506 equivalent, key selection criteria include peak repetitive reverse voltage (600V), average forward current (15A), surge capability (300A @ 8.3ms), thermal resistance (1.5°C/W), and UL recognition (E-326243).

Technical Context

The GBPC1506 implements a monolithic quad-diode bridge configuration with glass-passivated silicon junctions for stable high-voltage blocking and low leakage. Its integrally molded heatsink enables direct PCB mounting while maintaining R_θJC = 1.5°C/W for efficient thermal transfer to external heat sinks.

Rated for operation from –55°C to +150°C junction temperature, it supports high-reliability AC-DC front-end designs where surge immunity (300A I_FSM) and low IR (<5µA) are critical-particularly in switching mode power supplies operating at 50/60Hz input with transient line surges.

Key Specifications

Pinout & Package

GBPC1506 uses the standard GBPC through-hole package: 4-pin, single-in-line (SIL) layout with integrally molded heatsink base, matte tin-plated leads, UL 94V-0 molding compound, and cathode polarity marked on case.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving global industrial, computing, and consumer markets since 1979.

The GBPC series was designed specifically for high-current, high-reliability AC-DC conversion in industrial power supplies and equipment where thermal robustness, surge immunity, and safety certification are mandatory.

FAQ

What is the maximum junction temperature rating for GBPC1506?

The GBPC1506 has a maximum junction temperature (T_J) of +150°C and a minimum of –55°C. This wide operating range allows reliable deployment in enclosed industrial enclosures or high-ambient environments. Thermal design must ensure that actual junction temperature stays within this limit under worst-case load and ambient conditions. The GBPC1506's 1.5°C/W R_θJC enables precise heatsink sizing to maintain safe TJ during 15A continuous operation.

Is GBPC1506 UL recognized and RoHS compliant?

Yes, GBPC1506 is UL Recognized under file #E-326243 and fully RoHS compliant per EU Directive 2011/65/EU. The molding compound meets UL 94V-0 flammability rating, and terminals pass JESD 201 Class 1A whisker testing. These certifications validate its suitability for safety-critical industrial and commercial power equipment where regulatory compliance is mandatory. GBPC1506 documentation confirms both qualifications explicitly in the Mechanical Data and Ordering Information sections.

What does the "06" suffix indicate in GBPC1506?

The "06" in GBPC1506 specifies the peak repetitive reverse voltage rating: 600V. Per Taiwan Semiconductor's ordering convention, "005" = 50V, "01" = 100V, "02" = 200V, "04" = 400V, "06" = 600V, "08" = 800V, and "10" = 1000V. Thus, GBPC1506 is the 15A/600V variant of the GBPC15xx family. This coding applies uniformly across GBPC15, GBPC25, and GBPC35 series.

Can GBPC1506 be mounted directly to a heatsink?

Yes, GBPC1506 features an integrally molded heatsink base designed for direct mechanical attachment to external heatsinks using standard mounting hardware (max torque: 20 in-lbs). Its R_θJC of 1.5°C/W is measured from junction to case surface, enabling effective thermal transfer. No insulating washer is required unless electrical isolation from the heatsink is needed. Mounting must follow the specified torque to avoid case cracking or thermal interface degradation.

What is the forward voltage drop of GBPC1506 at rated current?

The GBPC1506 exhibits a typical forward voltage drop of ≤1.1 V per diode at 7.5A and 25°C junction temperature, measured under pulsed conditions (PW = 0.3ms). As a full-wave bridge, total conduction loss is approximately 2.2V at peak current. This value increases with temperature and current-designers should consult the Typical Forward Characteristics curve (Fig.4) for derating at elevated T_J or higher I_F. The GBPC1506's low V_F contributes directly to reduced power dissipation and improved system efficiency.
