Product details
Overview
GBU6J-M3/51 from Vishay General Semiconductor is a glass passivated single-phase bridge rectifier with 6.0 A average forward current, 600 V maximum repetitive peak reverse voltage, and 175 A non-repetitive surge capability. It features a GBU case, matte tin-plated leads, halogen-free RoHS-compliant construction (M3 suffix), and is designed for AC/DC full-wave rectification in switching mode power supplies and consumer electronics.
For engineers reviewing the GBU6J-M3/51 datasheet, GBU6J-M3/51 pinout, GBU6J-M3/51 application, or GBU6J-M3/51 equivalent, key selection criteria include its 600 V VRRM rating, 1.0 V forward voltage at 6.0 A, 5 μA reverse leakage at 25 °C, thermal resistance of 20 °C/W (RθJA), and compatibility with PCB mounting using 12 mm × 12 mm copper pads.
Technical Context
The GBU6J-M3/51 implements a standard in-line single-phase bridge configuration with four diodes arranged as two anti-parallel pairs across AC inputs and DC outputs. Its glass passivation ensures stable junction performance under thermal cycling and humidity exposure.
Rated for operation from –55 °C to +150 °C junction temperature, it supports high-surge applications with 127 A²s fusing I²t rating and 1500 VRMS dielectric strength between case and terminals - critical for isolation integrity in mains-connected power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - blocks up to 600 V repetitive reverse voltage, suitable for 420 V RMS input lines (e.g., 240 VAC systems with margin) |
| IF(AV) | 6.0 A at TC = 90 °C - continuous DC output current when heatsink-mounted; derates to 3.8 A at TA = 40 °C on PCB |
| VF @ 6.0 A | 1.0 V - total forward drop across two series diodes in conduction path, defining conduction loss in rectifier stage |
| IFSM | 175 A - withstands single half-sine surge without failure, supporting inrush current in SMPS input stages |
| IR @ 600 V | 5 μA at 25 °C - low leakage preserves efficiency and stability in high-impedance hold-up circuits |
| RθJA | 20 °C/W - thermal resistance from junction to ambient under PCB-mount conditions (12 mm × 12 mm copper pads) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6J-E3/51 | Same electrical specs and package; RoHS-compliant but contains brominated flame retardants (not halogen-free) | Acceptable where halogen-free requirement is not mandated (e.g., non-EU commercial shipments) | Select GBU6J-E3/51 only if M3 environmental compliance is not required; identical thermal and electrical behavior |
| KBU6J | Same 600 V VRRM, 6 A IF(AV), and GBU package; differs in lead finish (lead-free vs. matte tin) and JEDEC qualification level | Approved for automotive-grade extended temperature testing; higher screening cost and longer lead time | Choose KBU6J only for AEC-Q101 qualified designs; otherwise GBU6J-M3/51 offers optimal cost/performance balance for industrial/consumer use |
Compared with GBU6J-E3/51, the GBU6J-M3/51 adds halogen-free compliance without sacrificing electrical or thermal performance; versus KBU6J, it omits automotive qualification but delivers identical rectification capability at lower cost and broader availability for non-automotive applications.

FAQ
What is the maximum operating temperature for GBU6J-M3/51?
The GBU6J-M3/51 has a specified operating junction temperature range of –55 °C to +150 °C. Its maximum storage temperature matches this range. Derating curves show that average forward current drops from 6.0 A at TC = 90 °C to 3.8 A at TA = 40 °C under PCB-mount conditions, confirming thermal limits must be respected in layout design. The GBU6J-M3/51 must be mounted with appropriate copper area or heatsinking to avoid exceeding TJ max.
Does GBU6J-M3/51 support wave soldering?
Yes, the GBU6J-M3/51 supports wave soldering per JESD 22-B106: maximum solder dip temperature is 275 °C for up to 10 seconds. Its matte tin-plated leads comply with J-STD-002 for solderability, and the GBU package's UL 94 V-0 molding compound resists thermal degradation during soldering. Proper preheating and flux selection are recommended to avoid thermal shock or delamination.
What does the "M3" suffix mean in GBU6J-M3/51?
The "M3" suffix in GBU6J-M3/51 indicates halogen-free, RoHS-compliant construction meeting JEDEC J-STD-20 and JESD201 Class 1A whisker test requirements. Unlike the E3 variant, M3 uses non-brominated flame retardants in the epoxy molding compound. This makes GBU6J-M3/51 suitable for markets enforcing strict halogen restrictions, such as EU WEEE and certain automotive Tier 1 specifications.
Can GBU6J-M3/51 replace GBU6J-E3/51 in existing designs?
Yes, GBU6J-M3/51 is a direct form-fit-function replacement for GBU6J-E3/51: identical package dimensions, pinout, electrical ratings, and thermal characteristics. The only difference is the halogen-free molding compound in the M3 version. No PCB or firmware changes are needed; however, requalification may be required for safety certifications referencing material composition.
What is the typical junction capacitance of GBU6J-M3/51?
The typical junction capacitance (CJ) of GBU6J-M3/51 is 68 pF per diode at 4 V and 1 MHz, as measured in the Vishay datasheet. This value impacts high-frequency noise coupling and EMI filter design in SMPS inputs. Because the GBU6J-M3/51 contains four diodes in bridge configuration, total input-to-output capacitance is not additive but remains dominated by individual diode junctions referenced to common nodes.
