Product details
Overview
W10G-E4/51 from Vishay General Semiconductor is a glass passivated single-phase bridge rectifier with 1000 V peak reverse voltage, 1.5 A average forward current, and 50 A surge capability, used in AC/DC full-wave rectification for consumer power adapters and lighting ballasts.
For engineers reviewing the W10G-E4/51 datasheet, W10G-E4/51 pinout, W10G-E4/51 application, or W10G-E4/51 equivalent, key selection criteria include VRRM = 1000 V, IF(AV) = 1.5 A, VF = 1.0 V at 1.0 A, IR = 5.0 μA at 25 °C, and WOG package thermal resistance RθJA = 36 °C/W.
Technical Context
This device implements a quad-diode bridge configuration in a single WOG molded package, enabling full-wave rectification without external interconnection. It supports resistive, inductive, and capacitive loads per JEDEC-standard derating curves.
Thermal performance is defined by RθJA = 36 °C/W and RθJL = 11 °C/W (at 9.5 mm lead length on 5.5 mm × 5.5 mm PCB copper), with junction temperature rated from –55 °C to +150 °C and fusing I²t = 10 A²s.
Key Specifications

| IF(AV) | 1.5 A - average forward rectified current at 25 °C with 9.5 mm lead length; sets continuous DC output capability |
| IFSM | 50 A - non-repetitive peak surge current; withstands inrush during cold-start of switch-mode supplies |
| VF | 1.0 V at 1.0 A - forward voltage drop per diode; determines conduction loss and thermal load at nominal current |
| IR | 5.0 μA at 25 °C - maximum DC reverse leakage per diode; ensures low standby power in off-state |
| TJ max. | +150 °C - maximum operating junction temperature; enables use in enclosed, thermally constrained environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU10K-E4/51 | Same 1000 V VRRM and 1.5 A IF(AV), but GBU package (larger footprint, higher RθJA = 45 °C/W) | Better suited for forced-air-cooled or lower-power-density layouts where larger pad area is acceptable | Select when board space permits larger package and thermal design accommodates higher junction rise |
| KBP1010-E4/51 | 1000 V VRRM, 1.0 A IF(AV), smaller KBP package, RθJA = 40 °C/W | Limited to ≤12 W continuous output; lower surge rating (30 A vs. 50 A) | Choose only for space-constrained, lower-power applications where 50 A surge immunity is not required |
Compared with GBU10K-E4/51 and KBP1010-E4/51, the W10G-E4/51 delivers superior thermal efficiency (RθJA = 36 °C/W) and higher surge resilience (50 A) in a compact WOG outline, making it optimal for cost-sensitive, medium-power consumer and industrial rectification where PCB real estate and transient robustness are balanced.

FAQ
What is the maximum junction temperature rating for W10G-E4/51?
The W10G-E4/51 has a maximum junction temperature (TJ max.) of +150 °C, allowing reliable operation in thermally demanding environments such as enclosed power adapters or high-ambient industrial control panels. This rating is validated per JEDEC test conditions and supports derated current operation up to 125 °C ambient with appropriate PCB copper area. The W10G-E4/51 must be mounted with 0.375" (9.5 mm) lead length on a minimum 5.5 mm × 5.5 mm copper pad to achieve specified thermal resistance.
Does W10G-E4/51 meet RoHS requirements?
Yes, the W10G-E4/51 is RoHS-compliant, as indicated by the "E4" suffix in its ordering code. It conforms to EU Directive 2011/65/EU and subsequent amendments, with lead-free terminations and halogen-free molding compound meeting Vishay's material categorization standard (document 99912). The W10G-E4/51 is rated for commercial-grade applications and carries UL recognition file E54214.
What is the forward voltage drop of W10G-E4/51 at rated current?
The W10G-E4/51 exhibits a maximum instantaneous forward voltage (VF) of 1.0 V per diode at IF = 1.0 A and TA = 25 °C. Since the device contains four series-connected diodes in bridge configuration, total conduction loss across the bridge is approximately 2.0 V at 1.0 A DC output. This VF value is measured under pulsed conditions and remains stable over the –55 °C to +150 °C operating range, supporting predictable thermal design for the W10G-E4/51.
Can W10G-E4/51 replace W08G-E4/51 in a design?
Yes, the W10G-E4/51 can directly replace W08G-E4/51 because both share identical WOG package, pinout, IF(AV) = 1.5 A, IFSM = 50 A, and thermal characteristics, differing only in VRRM (1000 V vs. 800 V). The higher reverse voltage margin of the W10G-E4/51 improves surge tolerance in 230 VAC regions and extends design lifetime. No PCB or schematic changes are needed when upgrading from W08G-E4/51 to W10G-E4/51.
What is the reverse leakage current specification for W10G-E4/51?
The W10G-E4/51 specifies a maximum DC reverse current (IR) of 5.0 μA per diode at rated VDC = 1000 V and TA = 25 °C. At elevated temperature (TA = 125 °C), IR increases to 500 μA - a typical behavior for silicon rectifiers. This low leakage supports energy-efficient standby modes in modern power supplies. The W10G-E4/51 achieves this performance via glass passivation and optimized junction design, verified per the 88769 datasheet.
