Product details
Overview
B380C1500G-E4/51 from Vishay Semiconductors is a glass passivated single-phase bridge rectifier in WOG package, rated for 600 V repetitive peak reverse voltage (VRRM), 1.5 A average forward output current (IF(AV)), and 50 A non-repetitive peak surge current (IFSM), used in AC/DC full-wave rectification for consumer power adapters and lighting ballasts.
For engineers reviewing the B380C1500G-E4/51 datasheet, B380C1500G-E4/51 pinout, B380C1500G-E4/51 application, or B380C1500G-E4/51 equivalent, key selection criteria include VRMS rating (380 V), thermal resistance (RθJA = 36 °C/W), maximum junction temperature (125 °C), and RoHS-compliant silver-plated leads solderable per J-STD-002.
Technical Context
This device implements a four-diode full-wave bridge configuration with common-cathode/common-anode topology, enabling bidirectional AC input conversion to unidirectional DC output without center-tapped transformers. Its glass passivation ensures stable reverse leakage (IR ≤ 10 μA at rated VRRM) and high dielectric strength under humid or contaminated PCB environments.
The WOG package features molded UL 94 V-0 compound and 0.375" lead lengths mounted on 5.5 mm × 5.5 mm copper pads, supporting thermal derating curves specific to capacitive loads up to 200 μF and resistive/inductive loads across -40 °C to +125 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse voltage the bridge withstands without breakdown during AC line transients. |
| VRMS | 380 V - Maximum RMS input voltage for R- and C-load operation, defining safe AC mains interface capability. |
| IF(AV) | 1.5 A - Average DC output current sustainable at TA = 45 °C with free-air convection cooling. |
| IFSM | 50 A - Peak surge current tolerance for one 60 Hz half-cycle, critical for inrush protection in capacitor-input supplies. |
| VF @ 1.5 A | 1.0 V - Forward voltage drop per diode, determining total bridge conduction loss (≈2.0 V at full load). |
| TJ max. | 125 °C - Maximum junction temperature limit, constraining thermal design margin in enclosed adapters. |
| RθJA | 36 °C/W - Junction-to-ambient thermal resistance on standard PCB layout, used to calculate temperature rise under load. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6K-E4/51 | Same WOG package, 600 V VRRM, but rated IF(AV) = 6 A and IFSM = 175 A; VF = 1.1 V @ 6 A. | Higher current capacity suits higher-power supplies (>30 W); larger thermal mass requires different PCB copper layout. | Select when scaling output power while retaining same footprint and mounting method. |
| DB107S | Smaller SMD DB-1 package, 1000 V VRRM, IF(AV) = 1.0 A, IFSM = 30 A; VF = 1.1 V @ 1.0 A. | Surface-mount form factor reduces assembly cost but lowers surge rating and thermal dissipation vs. axial WOG. | Choose for space-constrained designs where 30 A surge and 1.0 A average current suffice. |
Compared with GBU6K-E4/51 and DB107S, B380C1500G-E4/51 delivers optimal balance of surge robustness (50 A), thermal performance (36 °C/W), and compact axial-leaded form for mid-power (<20 W) consumer-grade AC/DC supplies.

FAQ
What is the maximum allowable VRMS for B380C1500G-E4/51 in continuous operation?
The B380C1500G-E4/51 is rated for a maximum RMS input voltage of 380 V under R- and C-load conditions at TA = 25 °C. This value is derived from its 600 V VRRM rating and accounts for standard AC line tolerances and waveform crest factors. Operation above 380 V RMS risks exceeding reverse voltage limits during peak cycles and must be avoided unless validated with derating per Figure 2 in the datasheet.
Does B380C1500G-E4/51 support lead-free soldering processes?
Yes, B380C1500G-E4/51 features silver-plated leads compliant with J-STD-002 and JESD22-B102, qualified for lead-free soldering up to 275 °C for 10 seconds. The "E4" suffix confirms RoHS-compliant construction, and the device is compatible with standard reflow and wave-solder profiles meeting IPC-J-STD-020 moisture sensitivity level (MSL) requirements.
What is the typical reverse leakage current of B380C1500G-E4/51 at rated voltage and temperature?
The B380C1500G-E4/51 exhibits a maximum reverse current (IR) of 10 μA per diode at 600 V VRRM and TA = 25 °C. At elevated junction temperatures (e.g., 100 °C), IR increases exponentially but remains below 100 μA due to glass passivation, ensuring stable performance in thermally stressed consumer power supplies.
How does the WOG package of B380C1500G-E4/51 affect thermal management on PCB?
The WOG package of B380C1500G-E4/51 provides a junction-to-ambient thermal resistance (RθJA) of 36 °C/W when mounted on 5.5 mm × 5.5 mm copper pads with 0.375" lead lengths. This value assumes standard FR-4 board thickness and no internal copper planes; adding thermal vias or increasing pad area can reduce RθJA by up to 30 % in production layouts.
Can B380C1500G-E4/51 be used in capacitive-input filter configurations?
Yes, B380C1500G-E4/51 is explicitly characterized for capacitive-load operation, with a maximum rated load capacitance (CL) of 200 μF at 380 V VRMS. The datasheet provides derating curves (Figure 2) showing reduced IF(AV) versus CL, and recommends minimum series resistance (RT = 12 Ω) to limit inrush current and prevent contact welding in high-C applications.
