Product details
Overview
GBL01 from Vishay General Semiconductor is a glass passivated single-phase bridge rectifier with 100 V maximum repetitive peak reverse voltage (VRRM), 4 A average forward rectified output current (IF(AV)), and 150 A peak forward surge current (IFSM). It features 1.0 V forward voltage drop at 4.0 A, 5 μA DC reverse current at rated voltage, and operates from –55 °C to +150 °C junction temperature. It is used in AC/DC full-wave rectification for SMPS, adapters, and audio equipment.
For engineers reviewing the GBL01 datasheet, GBL01 pinout, GBL01 application, or GBL01 equivalent, key selection criteria include VRRM rating, thermal resistance (RθJC = 3.5 °C/W), PCB-mountable GBL package, UL E54214 recognition, and compatibility with J-STD-002 solderability standards.
Technical Context
The GBL01 implements a standard single-phase full-wave bridge configuration using four silicon diodes in an in-line GBL case. Its glass passivation ensures stable reverse leakage (<5 μA at 25 °C) and high dielectric strength under transient conditions.
Thermal performance is defined for two mounting conditions: PCB-mounted (RθJA = 22 °C/W) and heatsink-mounted on aluminum plate (RθJC = 3.5 °C/W). The device supports surge currents up to 150 A (8.3 ms sine wave) and fusing I²t of 93 A²s.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBL01E | RoHS-compliant (E3 suffix), same VRRM/IF(AV)/IFSM ratings, identical GBL package and pinout | No functional difference; intended as direct replacement for new designs requiring RoHS compliance | Select GBL01E for commercial-grade, lead-free assembly; verify solder profile compatibility with matte tin plating |
| GBU4K | Same 100 V VRRM and 4 A IF(AV), but GBU package (larger footprint, higher RθJA = 35 °C/W) | Less suitable for space-constrained PCBs; requires larger copper area or heatsink for equivalent thermal performance | Choose GBU4K only if GBL footprint unavailable; expect ~11 °C/W higher junction-to-ambient resistance |
Compared with GBL01, the GBL01E offers identical electrical and mechanical performance with RoHS compliance, while the GBU4K provides equivalent ratings in a physically larger package with reduced thermal efficiency-making GBL01 optimal for compact, thermally managed designs.

FAQ
What is the maximum operating temperature for GBL01?
The GBL01 has a specified operating junction and storage temperature range of –55 °C to +150 °C. This allows reliable use in environments such as enclosed power supplies or industrial enclosures where ambient temperatures may exceed 85 °C. Derating curves in the datasheet define safe current limits above 50 °C case temperature. The GBL01 must be mounted per recommended PCB pad layout or heatsink to maintain TJ ≤ 150 °C under full load.
Is GBL01 compatible with lead-free soldering processes?
Yes, the GBL01 features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, supporting both SnPb and lead-free reflow profiles. Maximum solder dip temperature is 275 °C for 10 seconds per JESD 22-B106. For GBL01, ensure peak reflow temperature does not exceed 260 °C for ≤ 30 seconds to preserve passivation integrity and avoid delamination.
Does GBL01 have UL safety certification?
Yes, the GBL01 carries UL recognition under file number E54214, confirming compliance with UL 60950-1 and UL 62368-1 for use in information technology and audio/video equipment. This certification covers flammability (UL 94 V-0), dielectric strength, and construction requirements-critical for end-product safety approvals when using GBL01 in regulated power supplies.
What is the forward voltage drop of GBL01 at rated current?
The GBL01 exhibits a maximum instantaneous forward voltage drop of 1.0 V per diode at 4.0 A and 25 °C. Since a bridge conducts through two diodes in series during each half-cycle, the total forward drop across the GBL01 is approximately 2.0 V under full-load conduction. This value increases with temperature and must be factored into efficiency calculations and thermal design for the GBL01.
How does GBL01 differ from GBL01E?
The GBL01E is the RoHS-compliant version of GBL01, featuring the E3 suffix indicating compliance with JEDEC JESD201 Class 1A whisker testing and lead-free plating. Electrically and mechanically identical-including pinout, package dimensions, and all ratings-the GBL01E replaces GBL01 in new designs requiring environmental compliance. The GBL01 remains available for legacy builds where RoHS exemption applies.
