Product details
Overview
B380C1000G-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), 1.0 A average forward output current (IF(AV)) under capacitive load at TA = 45 °C, and 45 A non-repetitive peak surge current (IFSM); used in AC/DC full-wave rectification for consumer appliance power supplies and lighting ballasts.
For engineers reviewing the B380C1000G-E4/51 datasheet, B380C1000G-E4/51 pinout, B380C1000G-E4/51 application, or B380C1000G-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 per J-STD-002.
Technical Context
This device implements a monolithic four-diode bridge configuration with common-cathode and common-anode terminals, enabling full-wave rectification without external interconnection. Its glass passivation ensures stable reverse leakage (IR ≤ 10 μA at rated VRRM) and high dielectric strength across the case.
The WOG package features 0.22" × 0.22" (5.5 mm × 5.5 mm) copper pad layout compatibility and supports solder dip up to 275 °C for 10 s (JESD 22-B106). Thermal performance is defined for free-air operation with specified derating curves for R-, L-, and C-load conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6K | 600 V VRRM, 6 A IF(AV), larger GBU package (18.5 mm × 13.5 mm) | Higher current capacity but requires more PCB area; higher thermal mass slows transient response | Select when >1.0 A continuous load or enhanced surge margin is required; verify footprint compatibility |
| DB107S | 1000 V VRRM, 1.0 A IF(AV), smaller SMD DO-214AA package | Higher voltage rating suits universal-input designs; lower VRMS (700 V) and different thermal profile | Prefer for space-constrained layouts where 1000 V isolation is mandatory; check CL derating for C-load stability |
Compared with B380C1000G-E4/51, GBU6K offers higher current headroom at the cost of size and thermal inertia, while DB107S trades voltage margin and package miniaturization for reduced thermal dissipation capability and altered capacitance loading limits.

FAQ
What is the maximum allowable ambient temperature for continuous operation of B380C1000G-E4/51?
The B380C1000G-E4/51 is rated for continuous operation up to 45 °C ambient temperature under capacitive load conditions to maintain its 1.0 A IF(AV) rating. At higher ambient temperatures, derating is required per Figure 2 in the datasheet; for example, at 70 °C ambient, the usable IF(AV) drops to approximately 0.75 A for C-load configurations with typical PCB copper pad layout.
Does B380C1000G-E4/51 support lead-free reflow soldering?
Yes, B380C1000G-E4/51 features E4-suffix RoHS-compliant silver-plated leads qualified to J-STD-002 solderability standards. It supports lead-free reflow profiles with peak temperatures up to 260 °C and is also rated for solder dip at 275 °C for 10 seconds per JESD 22-B106, making it compatible with both automated SMT assembly and selective soldering processes.
What is the minimum recommended series resistor for B380C1000G-E4/51 in a 380 V RMS capacitive-input application?
For VRMS = 380 V (±10 %), the datasheet specifies a minimum series resistor RT of 12 Ω for B380C1000G-E4/51 to limit inrush current and ensure safe charging of the bulk capacitor. This value assumes worst-case line voltage tolerance and accounts for the device's 45 A IFSM rating and thermal time constant under typical PCB mounting conditions.
How does the junction-to-ambient thermal resistance of B380C1000G-E4/51 compare to similar bridge rectifiers in SOIC-8 packages?
B380C1000G-E4/51 has a typical RθJA of 36 °C/W when mounted on a PCB with 0.22" × 0.22" (5.5 mm × 5.5 mm) copper pads. This is significantly lower than most SOIC-8 bridge rectifiers (typically 50–70 °C/W), due to the WOG package's larger thermal pad area and optimized leadframe design-enabling higher power density without heatsinking in consumer-grade applications.
Can B380C1000G-E4/51 be used in place of B250C1000G in an existing design?
Yes, B380C1000G-E4/51 is a direct upgrade from B250C1000G with identical WOG package, pinout, and thermal characteristics, but offers higher VRMS (380 V vs. 250 V) and VRRM (600 V vs. 400 V). No PCB changes are needed; however, system-level validation of surge immunity and filter capacitor stress under 380 V RMS operation is recommended before deployment.
