Product details

Overview

GBPC2504 from Diodes Incorporated is a 25A glass passivated single-phase bridge rectifier with 400V peak repetitive reverse voltage (VRRM), 1.1V forward voltage per diode at 12.5A, 300A non-repetitive surge rating, and metal-base thermal design for heatsink mounting in industrial power supplies and AC/DC converters.

For engineers reviewing the GBPC2504 datasheet, GBPC2504 pinout, GBPC2504 application, or GBPC2504 equivalent, key selection factors include its 400V blocking capability, 25A average output current at TC = 60°C, 1.3°C/W junction-to-case thermal resistance, and UL-recognized isolation rating of 1500V.

Technical Context

This discrete bridge rectifier integrates four silicon diodes in a single molded plastic package with internal heatsink, configured as a full-wave Graetz bridge. It operates under single-phase, half-wave 60Hz AC input with resistive or inductive loads, requiring 20% current derating for capacitive loads.

Thermal performance relies on mechanical mounting via #10 screw to an external heatsink; case-to-terminal isolation is rated at 1500V, and junction temperature must remain within –65°C to +150°C across operation and storage.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	400 V - Maximum peak reverse voltage each diode can block without breakdown
IO @ TC=60°C	25 A - Continuous DC output current achievable with case temperature maintained at 60°C
VFM @ IF=12.5A	1.1 V - Forward voltage drop per diode leg, directly determining conduction loss in power stage
IFSM	300 A - Peak surge current tolerance for 8.3ms half-sine wave, critical for inrush handling
RθJC	1.3 °C/W - Thermal resistance from junction to case, defining minimum heatsink requirement for thermal management
Isolation Voltage	1500 V - Dielectric strength between case and terminals, enabling safe mains-side mounting
CT @ 1MHz	300 pF - Total junction capacitance per diode, influencing EMI behavior in high-frequency switching environments

Pinout & Package

Package: GBPC - Molded plastic case with integrated metal baseplate for screw-mount heatsinking (UL 94V-0), dimensions 28.3–28.8 mm × 7.4–8.25 mm × 16.1–17.1 mm, weight ≈20 g.

Pin/Terminal	Circuit Role	Design Meaning
AC1 / AC2	AC Input Terminals	Two alternating current inputs accepting full-wave bridge input; electrically symmetrical

Applications

Industrial AC/DC Power Supplies

Motor Drive Front-End Rectification

Use Scenario: Converting 230VAC mains to unregulated DC bus in DIN-rail mounted power supplies for PLCs and I/O modules.

IC Role / Device Role / Timing Role: Discrete bridge rectifier providing full-wave AC-to-DC conversion at 25A continuous load.

Use Value: 400V VRRM safely accommodates 230VAC ±10% with margin; metal base enables compact heatsink integration in space-constrained enclosures.

Use Scenario: Rectifying single-phase AC input feeding DC link capacitors in HVAC blower and pump inverters.

IC Role / Device Role / Timing Role: Primary front-end rectifier converting utility AC into stable DC bus prior to PWM inverter stage.

Use Value: 300A IFSM handles motor inrush currents; low 1.1V VFM reduces conduction loss and thermal stress during continuous operation.

Welding Equipment Power Stages

Uninterruptible Power Supply (UPS) Input Stage

Use Scenario: High-current rectification in portable arc welding units operating from 115/230VAC generators or grid sources.

IC Role / Device Role / Timing Role: Main AC input rectifier delivering high-pulse DC current to energy storage and inverter sections.

Use Value: 25A IO rating supports intermittent high-duty-cycle loads; 1500V isolation ensures operator safety during high-voltage transients.

Use Scenario: Mains rectification in line-interactive UPS systems where battery backup engages during brownouts or outages.

IC Role / Device Role / Timing Role: Input-stage bridge converting utility AC to DC for charging battery and powering inverter during normal operation.

Use Value: Glass passivation ensures low IR drift over time, maintaining efficiency and thermal stability across 10+ year deployments.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
GBJ2504	Same 400V VRRM and 25A IO rating, but GBJ package uses insulated plastic body without metal baseplate; RθJC = 1.8°C/W vs. 1.3°C/W	Lower thermal performance requires larger heatsink area or forced-air cooling in high-ambient environments	Select when isolation from heatsink is required or when board-level mounting replaces screw-mount configuration
KBPC2504	Identical electrical specs (400V/25A/300A), but KBPC package has different mechanical footprint and terminal geometry; no UL recognition	Lacks UL E94661 listing, limiting use in certified industrial equipment requiring safety agency approval	Select only for cost-sensitive, non-certified consumer-grade power supplies where UL compliance is not mandated

Compared with GBJ2504 and KBPC2504, GBPC2504 uniquely combines UL recognition, lowest thermal resistance (1.3°C/W), and screw-mount metal base-making it optimal for thermally demanding, safety-certified industrial rectification where heatsink integration and regulatory compliance are mandatory.

FAQ

What is the maximum allowable case temperature for continuous operation of GBPC2504?

The datasheet specifies a maximum case temperature (TC) of 60°C for rated 25A average output current. Exceeding this temperature requires linear derating per Figure 1: at TC = 100°C, IO drops to approximately 15A. Thermal design must ensure heatsink interface resistance and ambient conditions maintain TC ≤ 60°C under full load.

Can GBPC2504 be used with capacitive loads without modification?

No. The datasheet explicitly requires a 20% derating of average output current when driving capacitive loads due to higher peak charging currents. For example, at TC = 60°C, IO must be limited to 20A instead of 25A. Additional input filtering or inrush limiting may be necessary to prevent overstress.

Does GBPC2504 have lead-free and RoHS-compliant construction?

Yes. GBPC2504 features lead-free finish and complies with RoHS Directive 2011/65/EU (as revised March 2013), including exemptions for glass and high-temperature solder per EU Annex Notes 5 and 7. This is confirmed in Note 4 of the DS21209 datasheet.

How is polarity marked on the GBPC2504 package?

Polarity is physically marked on the case: "+" and "–" symbols identify the DC output terminals, while "AC" labels (or dual "~") indicate the two AC input terminals. The standard GBPC orientation places "+" at top-right and "–" at top-left when viewing the device with terminals facing upward and marking side visible.
