Product details
Overview
BU1506-E3/51 from Vishay General Semiconductor is a 600 V, 15 A average current, enhanced isoCink+™ single-in-line bridge rectifier in BU package with glass-passivated junctions, rated for 200 A non-repetitive surge and 0.87 V forward voltage at 7.5 A and 125 °C, used in AC/DC full-wave rectification for switching power supplies and white-goods motor drives.
For engineers reviewing the BU1506-E3/51 datasheet, BU1506-E3/51 pinout, BU1506-E3/51 application, or BU1506-E3/51 equivalent, key selection factors include peak reverse voltage (600 V), thermal resistance (2.5 °C/W junction-to-case), RoHS-compliant matte tin leads, UL E312394 recognition, and compatibility with 60 W heatsinks for sustained 15 A operation.
Technical Context
The BU1506-E3/51 implements a four-diode full-bridge configuration in a thin single-in-line (SIL) package with internal isoCink+™ thermal architecture, enabling superior heat transfer from silicon to case. Its glass-passivated chip junction ensures stable reverse leakage (<5 μA at 25 °C) and robust surge handling (200 A IFSM, 160 A²s I²t).
Designed for high-reliability AC/DC conversion, it supports continuous operation up to 150 °C junction temperature and meets JESD 22-B106 solder dip requirements (275 °C, 10 s). Polarity is marked on body with beveled corner indicating positive lead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands repetitive reverse voltage up to 600 V without breakdown, suitable for 230 VAC mains-derived designs with safety margin. |
| IF(AV) | 15 A at TC = 80 °C - Delivers 15 A average forward current when case temperature is maintained at 80 °C, typically with 60 W heatsink. |
| IFSM | 200 A - Handles 8.3 ms single half-sine surge, supporting inrush current limiting in SMPS input stages. |
| VF @ 7.5 A, 125 °C | 0.87 V - Low conduction loss improves efficiency and reduces thermal stress in high-temperature environments. |
| RθJC | 2.5 °C/W - Enables precise thermal design: 15 A operation at 80 °C case requires ≤17.5 W dissipation (P = IF × VF ≈ 13.1 W typical). |
| IR @ 25 °C | ≤5 μA - Ensures minimal leakage in standby or low-power modes, critical for energy-efficient appliance standby compliance. |
| UL File No. | E312394 - Certified for safety-critical applications requiring recognized isolation and dielectric strength (1500 V). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU15J-E3/51 | Same 600 V VRRM, 15 A IF(AV), but GBU package (larger footprint, 3.5 mm height vs BU's 5.3 mm), RθJA = 35 °C/W (vs 20 °C/W for BU1506). | Less thermally efficient in constrained spaces; requires larger PCB area and heatsink for same current. | Select when legacy GBU layout exists or when higher mechanical robustness is prioritized over thermal density. |
| GBU15K-E3/51 | 800 V VRRM (vs 600 V), identical IF(AV), IFSM, and package; VF slightly higher (0.92 V typ @ 7.5 A, 125 °C). | Supports 400 VAC industrial inputs or designs requiring extra reverse margin; minor efficiency trade-off. | Select for universal-input (90–264 VAC) or 400 VAC three-phase rectification where 600 V margin is insufficient. |
Compared with GBU15J-E3/51 and GBU15K-E3/51, BU1506-E3/51 offers optimal thermal density (2.5 °C/W RθJC) in a low-profile BU package for space-limited white-goods, while GBU15K-E3/51 trades 0.05 V higher VF for 200 V extra reverse rating-critical for universal-input SMPS.

FAQ
What is the maximum junction temperature rating for BU1506-E3/51?
The BU1506-E3/51 has a maximum operating junction temperature of +150 °C, validated across its full electrical specification range. This rating enables reliable operation in sealed, high-ambient environments such as refrigerator control modules or enclosed power supplies. Derating curves in the datasheet define safe current limits at elevated temperatures, and the device must be mounted with appropriate thermal interface to avoid exceeding TJ max during sustained 15 A conduction.
Does BU1506-E3/51 support lead-free reflow soldering?
Yes, BU1506-E3/51 is qualified for lead-free reflow per JESD 22-B106: it withstands solder dip at 275 °C for up to 10 seconds. Its matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards, and the E3 suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance-making it suitable for modern automated SMT lines using Pb-free processes.
How does the isoCink+™ technology improve thermal performance in BU1506-E3/51?
isoCink+™ technology in BU1506-E3/51 enhances thermal conductivity between silicon die and package case, achieving a junction-to-case thermal resistance (RθJC) of 2.5 °C/W. This is significantly lower than standard bridge packages, allowing more efficient heat transfer to external heatsinks. As a result, BU1506-E3/51 sustains 15 A average current with a smaller 60 W-rated heatsink, reducing system size and cost in space-constrained applications like compact power adapters.
Is BU1506-E3/51 certified for safety-critical applications?
Yes, BU1506-E3/51 carries UL recognition file number E312394, confirming compliance with UL 60950-1/62368-1 for dielectric strength (≥1500 V), flammability (UL 94 V-0), and construction safety. This certification permits direct use in Class I and Class II isolated AC/DC systems without additional insulation barriers, simplifying safety approvals for home appliance and industrial power supply designs.
What is the difference between BU1506-E3/51 and BU1506-M3/51?
BU1506-E3/51 and BU1506-M3/51 share identical electrical and thermal specifications, but differ in material composition: E3 denotes RoHS-compliant commercial grade with standard molding compound, while M3 adds halogen-free formulation alongside RoHS compliance. Both meet JESD 201 Class 1A whisker testing and have identical packaging (paper tray, 250 units), making M3 preferred for environmentally sensitive markets requiring halogen-free declarations.
