Product details
Overview
BU1006-E3/45 from Vishay General Semiconductor is a 600 V, 10 A average current, enhanced isoCink+™ single-in-line bridge rectifier in BU package with glass-passivated junctions and UL E312394 recognition. It delivers 0.88 V forward voltage at 5.0 A and 125 °C, supports 120 A non-repetitive surge, and is rated for -55 °C to +150 °C operation - used in AC/DC full-wave rectification for switching power supplies and white-goods motor drives.
For engineers reviewing the BU1006-E3/45 datasheet, BU1006-E3/45 pinout, BU1006-E3/45 application, or BU1006-E3/45 equivalent, key selection criteria include peak reverse voltage (600 V), thermal resistance (3.0 °C/W junction-to-case), RoHS-compliant matte tin leads, UL safety approval, and compatibility with 60 W heatsinks for sustained 10 A output.
Technical Context
The BU1006-E3/45 integrates four silicon diodes in a single-in-line (SIL) configuration with internal + ~ ~ − and − ~ ~ + polarity layout, enabling full-wave bridge rectification without external interconnects. Its isoCink+™ construction improves thermal conduction from junction to case versus standard epoxy-packaged bridges.
Designed for high-reliability AC input stages, it features glass-passivated junctions for moisture resistance, JESD 22-B106-compliant solderability (275 °C, 10 s), and JESD 201 Class 1A whisker resistance on matte tin leads. The device operates up to 150 °C junction temperature with 5 μA max reverse leakage at rated VRRM and 25 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU10K-E3/45 | Same 10 A/600 V rating but GBU package (larger, 22.5 mm length); RθJA = 35 °C/W vs. BU's 20 °C/W | Better suited for PCB layouts with space for larger footprint and less aggressive thermal management | Select GBU10K-E3/45 if board real estate permits and heatsinking is less constrained |
| DB106S-E3/51 | Smaller SMD DB package (4.8 × 4.2 mm); lower IF(AV) = 1.0 A; not drop-in - requires layout redesign | Targeted at compact, low-power auxiliary supplies rather than main power rails | Choose DB106S-E3/51 only for space-constrained, sub-2 A applications where BU1006-E3/45 is over-specified |
Compared with GBU10K-E3/45 and DB106S-E3/51, the BU1006-E3/45 offers optimal balance of thermal performance (3.0 °C/W RθJC), compact SIL form factor, and UL safety certification - making it preferred for mid-power industrial and appliance designs requiring reliable through-hole mounting and proven field lifetime.

FAQ
What is the maximum junction temperature rating for BU1006-E3/45?
The BU1006-E3/45 has a maximum operating junction temperature of +150 °C, as specified in the Vishay datasheet Document Number 84801. This rating enables reliable operation in high-ambient environments like enclosed appliance cabinets or industrial enclosures. Derating curves show usable current drops linearly above 92 °C case temperature, and thermal design must respect the 3.0 °C/W RθJC limit to avoid exceeding TJ max during sustained 10 A load conditions. The BU1006-E3/45 must not be operated beyond this absolute maximum.
Is BU1006-E3/45 RoHS-compliant and halogen-free?
The BU1006-E3/45 is RoHS-compliant per EU Directive 2011/65/EU, as indicated by the "E3" suffix in its part number. However, it is not halogen-free - that designation applies only to the "M3" variant (e.g., BU1006-M3/45). The E3 version uses standard molding compound meeting UL 94 V-0 flammability rating but contains brominated flame retardants. For halogen-free requirements, BU1006-M3/45 must be specified instead; BU1006-E3/45 does not meet IEC 61249-2-21 or JEDEC JS709 definitions of halogen-free.
What is the forward voltage drop of BU1006-E3/45 at rated current?
The BU1006-E3/45 exhibits a typical forward voltage drop of 0.88 V per diode at IF = 5.0 A and TJ = 125 °C, as confirmed in the Electrical Characteristics table of Vishay Document 84801. Since the device contains four series-connected diodes in bridge configuration, total conduction loss across the conducting pair is approximately 1.76 V at that condition. At 25 °C, VF rises to 0.98 V typical per diode, resulting in ~1.96 V total drop - critical for calculating power dissipation and thermal design margins in BU1006-E3/45 applications.
Does BU1006-E3/45 require a heatsink for 10 A continuous operation?
Yes - the BU1006-E3/45 requires a 60 W air-cooled heatsink to sustain 10 A average forward current continuously, as stated in the Maximum Ratings table (Note 1). Without heatsink (free-air condition), its derated IF(AV) drops to 3.2 A at 25 °C ambient. The 3.0 °C/W RθJC value means even modest power dissipation (e.g., 10 A × 0.88 V ≈ 8.8 W) generates >26 °C junction-to-case rise - necessitating effective heatsinking to maintain TJ ≤ 150 °C. BU1006-E3/45 cannot operate at full 10 A rating without thermal management.
What safety certifications does BU1006-E3/45 hold?
The BU1006-E3/45 carries UL recognition under file number E312394, confirming compliance with UL 60747-1 for discrete semiconductors and validating dielectric strength ≥1500 V RMS. It also meets JESD 22-B106 (solder dip), JESD 22-B102 (solderability), and JESD 201 Class 1A (tin whisker resistance). These certifications apply directly to the BU1006-E3/45 unit - no additional testing or qualification is needed for end-equipment safety approvals when used per Vishay's recommended mounting and insulation guidelines.
