Product details

Overview

VS-GBPC2506A from Vishay Semiconductors is a single-phase bridge rectifier with 25 A average DC output current, 600 V maximum repetitive peak reverse voltage (V_RRM), and glass-passivated diode chips in an electrically insulated GBPC package. It delivers reliable AC-to-DC conversion in industrial power supplies and instrumentation front-ends where thermal stability and high surge tolerance are required.

For engineers reviewing the VS-GBPC2506A datasheet, VS-GBPC2506A pinout, VS-GBPC2506A application, or VS-GBPC2506A equivalent, key selection criteria include its 1.7 K/W junction-to-case thermal resistance, UL E300359 approval, 400 A non-repetitive surge rating at 10 ms, 2700 V RMS isolation voltage, and compatibility with Pb-free soldering (SAC305, 260–275 °C).

Technical Context

This device implements a full-wave single-phase bridge configuration using four glass-passivated silicon diodes integrated into a compact, molded plastic case with electrically insulated baseplate. Its thermal design supports direct mounting to heatsinks via center-hole fixing and achieves stable operation across -55 °C to +150 °C junction temperature range.

The VS-GBPC2506A exhibits dual forward voltage characteristics: low-level threshold voltage (V_F(TO)1) of 0.76 V and high-level slope resistance (r_t2) of 6.8 mΩ at T_J = 150 °C - enabling accurate power loss estimation under both resistive and capacitive load conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
I_O	25 A average DC output current at T_C = 60 °C - defines continuous conduction capability for mains-frequency rectification.
V_RRM	600 V maximum repetitive peak reverse voltage - sets safe AC input voltage limit (≈424 V RMS) before breakdown risk.
I_FSM	400 A non-repetitive surge current (10 ms, 50 Hz, no voltage reapplied) - determines short-circuit withstand capability during startup or fault events.
R_thJC	1.7 K/W junction-to-case thermal resistance - enables precise heatsink sizing for thermal management in enclosed power systems.
V_INS	2700 V RMS isolation voltage (50 Hz, 1 s) - certifies reinforced insulation between terminals and baseplate for safety-compliant designs.
V_F	1.1 V maximum forward voltage drop at T_J = 25 °C and I_FM = I_F(AV) - directly impacts conduction losses and efficiency in 50/60 Hz applications.
T_J	-55 °C to +150 °C operating junction temperature range - supports deployment in harsh industrial environments without derating penalties.

Pinout & Package

VS-GBPC2506A uses the GBPC...A package: a 4-terminal, insulated plastic housing with center mounting hole (Ø2.4 mm), dimensions 28.55 × 17.9 × 14.2 mm, and nickel-plated fast-on terminals rated for SAC305 soldering (260–275 °C). The case is electrically isolated from all terminals.

Pin/Terminal	Circuit Role	Design Meaning

AC2	AC input terminal 2	Second leg of AC input; connects to transformer secondary or neutral/line return; shares internal node with D3 anode and D4 cathode.
(+)	DC positive output	Full-wave rectified positive output node; formed by D1 and D3 cathodes; must connect to bulk capacitor or load positive rail.
(-)	DC negative output	Full-wave rectified negative output node; formed by D2 and D4 anodes; serves as system ground or return path reference.

Key Features

Equivalent & Alternatives

The following parts are listed as comparable options for similar bridge rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
GBPC2506W	Same electrical specs but wire-lead (W) instead of fast-on (A) terminals; lacks center mounting hole and insulated baseplate.	Suitable for PCB-mounted or chassis-wire applications; not recommended for direct heatsink mounting without external insulation.	Select GBPC2506W only when leaded termination and lower mechanical rigidity are acceptable; avoid in thermally demanding or safety-critical mounts.
VS-GBPC3506A	Higher 35 A I_O, lower 1.4 K/W R_thJC, same 600 V V_RRM, identical GBPC-A package footprint and pinout.	Enables future-proofing or margin expansion in high-load applications; requires no PCB layout change but may need larger heatsink for full utilization.	Choose VS-GBPC3506A when designing for >25 A continuous loads or when extended thermal headroom is needed for ambient temperature derating.

Compared with GBPC2506W, VS-GBPC2506A offers superior thermal management and safety isolation for heatsink-mounted designs; versus VS-GBPC3506A, it provides optimal cost-performance balance for 25 A-rated systems without over-spec'ing thermal capacity.

FAQ

What is the maximum allowable case temperature for continuous operation of the VS-GBPC2506A?

The VS-GBPC2506A supports 25 A average DC output current at a maximum case temperature (T_C) of 60 °C. Exceeding this temperature requires linear derating per Figure 6 in the datasheet - for example, at 80 °C T_C, the usable I_O drops to approximately 18 A. Thermal design must ensure the baseplate remains within this limit under worst-case ambient and airflow conditions.

Does the VS-GBPC2506A require external insulation when mounted to a metal heatsink?

No - the VS-GBPC2506A features an electrically insulated case rated for 2700 V RMS isolation. This allows direct mounting to grounded or floating heatsinks without additional insulating pads or hardware, simplifying thermal interface design and improving thermal transfer efficiency compared to non-insulated alternatives.

What soldering profile is recommended for the VS-GBPC2506A terminals?

The VS-GBPC2506A terminals are nickel-plated and qualified for Pb-free SAC305 (Sn/Ag/Cu) soldering at peak temperatures of 260–275 °C. Reflow profiles must comply with JEDEC J-STD-020, limiting time above 217 °C to ≤60 seconds and avoiding thermal shock during cooling to prevent package cracking or terminal delamination.

How does the VS-GBPC2506A compare to standard KBPC2506 bridge rectifiers in terms of reliability?

The VS-GBPC2506A uses glass-passivated diode chips and UL E300359-approved materials, delivering higher moisture resistance and longer operational life than epoxy-passivated KBPC variants. Its 1.7 K/W R_thJC and -55 °C to +150 °C T_J range further enhance reliability in thermally aggressive industrial deployments where KBPC2506 may exhibit premature failure.

Can the VS-GBPC2506A be used in 277 V AC lighting applications?

Yes - with a 600 V V_RRM, the VS-GBPC2506A supports peak line voltages up to ≈392 V, comfortably covering 277 V AC (392 V peak) with margin. Its UL E300359 approval and 2700 V isolation also meet safety requirements for commercial LED lighting systems operating on high-voltage AC distribution networks.
