Taiwan Semiconductor Corporation GBPC1502

Overview

GBPC1502 from Taiwan Semiconductor is a 15A, 200V standard single-phase bridge rectifier in GBPC package with quad diode configuration, glass-passivated junctions, and integrally molded heatsink; used in AC-DC conversion stages of switching mode power supplies where low thermal resistance (1.5°C/W) and high surge capability (300A IFSM) are critical.

For engineers reviewing the GBPC1502 datasheet, GBPC1502 pinout, GBPC1502 application, or GBPC1502 equivalent, key selection criteria include peak reverse voltage (200V), average forward current (15A), forward voltage drop (≤1.1V at 7.5A), reverse leakage (≤5µA), and thermal performance for convection-cooled industrial SMPS designs.

Technical Context

The GBPC1502 integrates four silicon diodes in a single-phase full-wave bridge configuration with common cathode and anode terminals. Its glass-passivated junction ensures stable reverse characteristics and low IR (<5µA at rated VRRM), while the molded heatsink enables direct PCB mounting with 1.5°C/W junction-to-case thermal resistance.

This device operates across -55°C to +150°C junction temperature range and supports repetitive 8.3ms half-sine surge currents up to 300A. It meets UL 94V-0 flammability rating and JESD201 Class 1A whisker resistance, with matte tin-plated leads compliant to J-STD-002 solderability.

Key Specifications

Pinout & Package

FAQ

What is the maximum junction temperature rating for GBPC1502?

The GBPC1502 has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version M2211). This rating defines the upper thermal limit for reliable operation; sustained operation above this temperature risks permanent degradation of the glass-passivated junction. Derating curves in the datasheet specify reduced current capability above +100°C case temperature. Thermal design must ensure GBPC1502 stays within this limit under worst-case load and ambient conditions.

Does GBPC1502 have UL recognition and what is the file number?

Yes, GBPC1502 is UL Recognized under File # E-326243, as confirmed in the "Features" section of the Taiwan Semiconductor GBPC15/25/35 Series datasheet (Version M2211). This recognition applies to the GBPC package family and validates compliance with UL 60950-1 and UL 62368-1 for use in end-equipment safety certification. The molded compound also meets UL 94V-0 flammability requirements, supporting its use in commercial and industrial power supplies.

What is the forward voltage drop specification for GBPC1502 and under what test conditions?

The GBPC1502 has a maximum forward voltage drop (VF) of 1.1 V per diode, measured at IF = 7.5 A, TJ = 25°C, with pulse test conditions (PW = 0.3 ms), as stated in the "Electrical Specifications" table of the Taiwan Semiconductor datasheet. This value reflects conduction loss in one diode leg during half-cycle conduction; total bridge drop is twice this under full-wave operation. At elevated temperatures or higher currents, VF increases-designers should consult the "Typical Forward Characteristics" curve (Fig.4) for accurate loss estimation.

Is GBPC1502 compatible with lead-free reflow soldering processes?

GBPC1502 features matte tin-plated leads qualified to J-STD-002 for solderability, but it is a through-hole device intended for wave or hand soldering-not lead-free reflow. Its GBPC package is not rated for SMT reflow profiles; peak temperatures exceeding 200°C risk molding compound damage or internal bond degradation. For lead-free assembly, use wave soldering with preheat ≤100°C and contact time ≤5 seconds. Refer to Taiwan Semiconductor's recommended soldering profile in the "Mechanical Data" section of the datasheet.

How does the GBPC1502 differ from GBPC1504 or GBPC1506 in terms of voltage rating?

The GBPC1502 is rated for 200 V repetitive peak reverse voltage (VRRM), whereas GBPC1504 is rated for 400 V and GBPC1506 for 600 V-all sharing identical 15 A IF(AV), 300 A IFSM, and GBPC package. The numeric suffix indicates voltage grade: "02" = 200 V, "04" = 400 V, "06" = 600 V. Selection depends on required safety margin over peak input voltage; GBPC1502 is appropriate for 120 VAC systems (170 V peak), while higher grades suit 230 VAC (325 V peak) or PFC-stage applications.
