Product details
Overview
VS-GBPC2512W from Vishay Semiconductors is a single-phase bridge rectifier with 25 A average forward current, 1200 V maximum repetitive peak reverse voltage (VRRM), and glass-passivated diode chips in an electrically insulated, thermally efficient GBPC package. It delivers reliable AC-to-DC conversion in industrial power supplies and instrumentation front-ends where high surge immunity and UL E300359 safety approval are required.
For engineers reviewing the VS-GBPC2512W datasheet, VS-GBPC2512W pinout, VS-GBPC2512W application, or VS-GBPC2512W equivalent, key selection criteria include its 1200 V blocking capability, 400 A non-repetitive surge rating at 10 ms, 1.7 K/W junction-to-case thermal resistance, and wire-lead (W) termination for through-hole PCB mounting with center-hole mechanical fixation.
Technical Context
This device implements a full-wave single-phase bridge configuration using four glass-passivated silicon diodes integrated into a molded plastic case with electrically insulated baseplate. Its thermal design supports DC operation up to 60 °C case temperature while maintaining 25 A output under resistive/inductive loads.
The VS-GBPC2512W features nickel-plated wire leads compatible with Pb-free soldering (SAC305, 260–275 °C), UL E300359 safety certification, and a rated RMS isolation voltage of 2700 V between baseplate and terminals - enabling use in mains-connected equipment requiring reinforced insulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IO | 25 A average DC output current at TC = 60 °C - defines continuous power handling under standard heatsinking |
| VRRM | 1200 V maximum repetitive peak reverse voltage - enables direct rectification of 850 V AC line inputs |
| IFSM | 400 A non-repetitive surge current (10 ms, no voltage reapplied) - withstands inrush and fault transients in industrial SMPS |
| RthJC | 1.7 K/W junction-to-case thermal resistance - determines minimum heatsink requirement for thermal management |
| VF | 1.1 V maximum forward voltage drop at TJ = 25 °C and IFM = IF(AV) - sets conduction loss and efficiency at rated load |
| VINS | 2700 V RMS isolation voltage (50 Hz, 1 s) - satisfies reinforced insulation requirements per safety standards |
Pinout & Package
VS-GBPC2512W uses the GBPC...W package: a compact, molded plastic housing with four insulated wire leads (AC1, AC2, (+), (−)) and a metal baseplate for heatsink mounting. Dimensions: 28.55 mm × 17.9 mm × 14.2 mm (L×W×H), weight ≈ 16 g, center mounting hole Ø2.4 mm.
| Pin/Terminal | Circuit Role | Design Meaning |

FAQ
What is the maximum allowable case temperature for continuous operation of the VS-GBPC2512W?
The VS-GBPC2512W supports continuous operation at a maximum case temperature (TC) of 60 °C when delivering its rated 25 A average forward current under resistive or inductive load conditions. Exceeding this temperature requires derating per the datasheet's current vs. case temperature curve, and thermal design must ensure the baseplate remains within this limit via adequate heatsinking.
Does the VS-GBPC2512W require external insulation when mounted to a grounded heatsink?
No - the VS-GBPC2512W features an electrically insulated case with a rated 2700 V RMS isolation voltage between terminals and baseplate. This allows direct mounting to grounded metal heatsinks without mica washers or insulating pads, simplifying thermal design and reducing assembly cost while maintaining safety compliance.
What soldering profile is recommended for the wire leads of the VS-GBPC2512W?
The VS-GBPC2512W wire leads are nickel-plated and qualified for Pb-free soldering using Sn/Ag/Cu (SAC305) alloy at peak temperatures between 260 °C and 275 °C. Reflow or wave soldering must comply with JEDEC J-STD-020 moisture sensitivity level (MSL) guidelines; the device is not moisture-sensitive and does not require baking prior to soldering.
How does the VS-GBPC2512W compare to the VS-GBPC3512W in terms of thermal performance?
The VS-GBPC2512W has a junction-to-case thermal resistance (RthJC) of 1.7 K/W, while the VS-GBPC3512W is rated at 1.4 K/W. Although the 35 A version offers lower thermal resistance, the VS-GBPC2512W maintains sufficient thermal margin for 25 A applications and provides tighter voltage drop consistency (1.1 V max) due to optimized die sizing - making it more efficient at its rated current.
Is the VS-GBPC2512W certified for use in safety-critical applications such as medical or automotive systems?
The VS-GBPC2512W carries UL E300359 recognition per UL/CSA 60950-1 and IEC/EN 62368-1, qualifying it for industrial and consumer power equipment. However, it is not AEC-Q101 qualified nor specifically designed for life-sustaining medical or automotive safety-critical systems; Vishay explicitly states that its products are not intended for such applications unless formally qualified in writing.
