Product details
Overview
B125C1000G-E4/51 from Vishay Semiconductors is a glass passivated single-phase bridge rectifier in WOG package, rated for 125 V repetitive peak reverse voltage (VRRM), 1.0 A average forward output current (IF(AV)), and 45 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 B125C1000G-E4/51 datasheet, B125C1000G-E4/51 pinout, B125C1000G-E4/51 application, or B125C1000G-E4/51 equivalent, key selection criteria include VRRM = 125 V, IF(AV) = 1.0 A at TA = 45 °C (C-load), VF = 1.0 V at 1.0 A, IR = 10 μA at rated VRRM, and thermal resistance RθJA = 36 °C/W with PCB copper pads.
Technical Context
This device integrates four silicon diodes in a single-phase bridge configuration with common-cathode and common-anode terminals, enabling full-wave rectification without external wiring. Its glass passivation ensures stable reverse leakage (IR ≤ 10 μA) and high dielectric strength across temperature.
The WOG package features silver-plated leads solderable per J-STD-002 and JESD22-B102, with UL 94 V-0 molding compound and polarity marked on body. Thermal performance is specified for 0.22" × 0.22" (5.5 mm × 5.5 mm) copper pads and 0.375" (9.5 mm) lead length.
Key Specifications

| VRRM | 125 V - maximum repetitive reverse voltage the bridge withstands without breakdown |
| IF(AV) | 1.0 A - average DC output current under capacitive load at TA = 45 °C |
| IFSM | 45 A - peak non-repetitive surge current capability for single half-sine wave |
| VF | 1.0 V at IF = 1.0 A - forward voltage drop per diode, defining conduction loss at rated load |
| IR | 10 μA at VRRM - total reverse leakage current of the bridge at rated voltage and 25 °C |
| RθJA | 36 °C/W - junction-to-ambient thermal resistance with specified PCB copper pad layout |
| TJ max. | 125 °C - maximum allowable junction temperature for continuous operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU2K | VRRM = 200 V, IF(AV) = 2.0 A, larger GBU package (RθJA ≈ 40 °C/W) | Higher voltage margin and current capacity; suited for 230 V AC regions or higher-power designs | Select when >125 V reverse stress or >1.0 A sustained load is required; PCB footprint differs |
| DB107S | VRRM = 1000 V, IF(AV) = 1.0 A, SMD SMB package (no leads) | Ultra-high VRRM for surge-prone environments; surface-mount only, no through-hole option | Choose for space-constrained layouts or where 1 kV isolation is mandated; not drop-in for WOG footprint |
Compared with B125C1000G-E4/51, GBU2K offers higher voltage/current headroom but requires layout change, while DB107S provides extreme VRRM in SMD form but lacks axial-leaded mechanical robustness and thermal path of WOG.

FAQ
What is the maximum ambient temperature for continuous operation of B125C1000G-E4/51?
The B125C1000G-E4/51 is rated for operation up to +45 °C ambient temperature when delivering its full 1.0 A average forward current under capacitive load. At higher ambient temperatures, derating is required per Fig. 1 in the datasheet; the absolute maximum junction temperature remains 125 °C. Thermal design must account for RθJA = 36 °C/W and PCB copper pad layout to ensure safe operation.
Does B125C1000G-E4/51 support 230 V AC input applications?
No, B125C1000G-E4/51 is rated for 125 V RMS input (VRMS = 125 V) and 125 V repetitive peak reverse voltage (VRRM = 125 V), making it suitable for 120 V AC regions only. For 230 V AC systems, a higher-voltage variant such as B250C1000G (VRRM = 400 V, VRMS = 250 V) is required to maintain safe reverse margin and avoid breakdown.
What does the "E4/51" suffix mean in B125C1000G-E4/51?
The "E4" suffix denotes RoHS-compliant, lead-free termination per EU directive; "51" is Vishay's preferred package code indicating bulk packaging in plastic bags (100 units per bag). This ordering code confirms commercial-grade qualification, silver-plated leads, and compliance with J-STD-002 solderability standards - all verified for B125C1000G-E4/51.
Can B125C1000G-E4/51 be used in place of a discrete diode bridge?
Yes, B125C1000G-E4/51 replaces four discrete 1N4007-type diodes in a single WOG package, offering identical full-wave bridge functionality with reduced assembly cost, improved reliability, and consistent matching of VF and IR across all four diodes. Its pinout (~, ~, +, −) maps directly to standard bridge layouts, simplifying PCB redesign.
Is thermal relief required for the leads of B125C1000G-E4/51 during PCB layout?
Yes, thermal relief is recommended for the + and − DC terminals of B125C1000G-E4/51 when connecting to large copper planes, as these carry full load current and contribute significantly to heat dissipation. The datasheet specifies thermal resistance based on 0.22" × 0.22" copper pads; unrestricted plane connections without relief may alter thermal performance and solder joint integrity during reflow.
