Vishay General Semiconductor - Diodes Division GBL02-E3/45

Overview

GBL02-E3/45 from Vishay General Semiconductor is a glass passivated single-phase bridge rectifier in GBL package, rated for 200 V repetitive peak reverse voltage (VRRM), 4 A average forward output current (IF(AV)), and 150 A non-repetitive surge current (IFSM). It delivers 1.0 V forward voltage at 4.0 A and exhibits only 5 μA DC reverse current at rated voltage, making it suitable for AC/DC full-wave rectification in compact power supplies.

For engineers reviewing the GBL02-E3/45 datasheet, GBL02-E3/45 pinout, GBL02-E3/45 application, or GBL02-E3/45 equivalent, key selection criteria include its 200 V VRRM rating, 4 A thermal-current capability with PCB or heatsink mounting, UL E54214 recognition, RoHS-compliant matte tin leads, and compatibility with J-STD-002 solderability standards.

Technical Context

This device implements a standard in-line single-phase bridge configuration with four series-connected diodes arranged as two anti-parallel pairs - enabling full-wave rectification of AC input without center-tapped transformers. Its glass passivation ensures stable junction characteristics under humidity and thermal cycling.

Thermal performance is defined by RθJC = 3.5 °C/W (junction-to-case) and RθJA = 22 °C/W (junction-to-ambient, PCB-mounted), supporting operation up to TJ = 150 °C. The 95 pF typical junction capacitance per diode at 4.0 V / 1 MHz influences high-frequency ripple behavior in switching applications.

FAQ

What is the maximum junction temperature rating for GBL02-E3/45?

The GBL02-E3/45 has a maximum junction temperature (TJ max.) of +150 °C. This rating defines the upper thermal limit for reliable operation and must be respected under all conditions - including worst-case ambient, power dissipation, and heatsinking. Derating curves in the Vishay datasheet (Document Number 88609) specify allowable IF(AV) reduction above 50 °C case temperature. Thermal design must ensure TJ remains ≤150 °C across the full lifetime of the GBL02-E3/45.

Does GBL02-E3/45 support lead-free reflow soldering?

Yes, GBL02-E3/45 supports lead-free reflow soldering per industry standards. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102, and the package withstands solder dip up to 275 °C for 10 seconds. While optimized for wave soldering, it is compatible with standard Pb-free reflow profiles (peak ~260 °C) when mounted on appropriate copper pads (0.5" x 0.5", 12 mm x 12 mm) as specified in the GBL02-E3/45 thermal data.

What does the "E3/45" suffix mean in GBL02-E3/45?

The "E3" suffix indicates RoHS-compliant construction with JESD 201 Class 1A whisker resistance, and "/45" denotes tube packaging with 20 units per tube. This ordering code identifies both environmental compliance and logistics format - critical for procurement, traceability, and assembly line setup. The GBL02-E3/45 is distinct from GBL02E (enhanced moisture resistance) and GBL02-E3/51 (anti-static tray packaging).

Is GBL02-E3/45 pin-compatible with other GBL-series rectifiers?

Yes, all GBL-series rectifiers - including GBL005-E3/45, GBL01-E3/45, GBL02-E3/45, GBL04-E3/45, etc. - share identical GBL package dimensions, lead spacing, and 4-pin in-line pinout (AC1, AC2, +, –). This allows direct substitution across voltage ratings (50 V to 1000 V) without PCB layout changes, provided thermal and surge requirements are verified for the specific application.

What is the typical junction capacitance of GBL02-E3/45 and how does it affect circuit performance?

The GBL02-E3/45 exhibits 95 pF typical junction capacitance per diode at 4.0 V and 1 MHz. This capacitance contributes to high-frequency reverse recovery behavior and influences EMI generation during commutation. In switch-mode supplies, it interacts with snubber networks and transformer leakage inductance - potentially increasing switching losses or requiring tighter EMI filtering. Designers should verify noise performance using actual GBL02-E3/45 measurements under operating conditions.
