Product details

Overview

GBPC1504 from Diodes Incorporated is a 15A glass passivated single-phase bridge rectifier with 400V peak repetitive reverse voltage (VRRM), 1.1V forward voltage at 7.5A per diode, and 300A non-repetitive surge rating. It features electrically isolated metal base for heatsink mounting, UL recognition (E94661), and RoHS-compliant lead-free finish. Used in AC/DC power supplies for industrial motor drives requiring high surge tolerance and thermal stability.

For engineers reviewing the GBPC1504 datasheet, GBPC1504 pinout, GBPC1504 application, or GBPC1504 equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (5.0°C/W junction-to-case), case isolation voltage (1500V), and through-hole mounting compatibility with #10 screw.

Technical Context

This bridge rectifier integrates four silicon diodes in a single molded plastic package with internal heatsink, configured as a full-wave Graetz circuit. Its glass passivated die construction ensures low reverse leakage (5.0μA at 25°C) and stable operation up to 150°C junction temperature.

The device is rated for 15A average output current at TC = 70°C with mandatory derating for capacitive loads (−20% current). Thermal performance relies on mechanical mounting to an external heatsink via its isolated metal base, enabling efficient power dissipation under continuous conduction mode.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	400 V - Maximum peak reverse voltage each diode withstands without breakdown; defines safe AC input range for 280V RMS systems.
IO @ TC=70°C	15 A - Continuous DC output current capability when case temperature is held at 70°C using heatsink mounting.
VFM @ IF=7.5A	1.1 V - Forward voltage drop per diode at half-rated current; determines conduction loss (≈16.5W total at full load).
IFSM	300 A - Single half-sine surge current rating (8.3ms); supports inrush limiting in transformer-coupled supplies.
RθJC	5.0 °C/W - Junction-to-case thermal resistance; requires heatsink design achieving ≤55°C case rise for 15A operation at 150°C max TJ.
Isolation Voltage	1500 V - Dielectric strength between case and terminals; enables safe mounting on grounded heatsinks in Class I equipment.
IR @ 25°C	5.0 μA - Reverse leakage per diode at rated blocking voltage; critical for low-power standby circuits and precision DC references.

Pinout & Package

Package: GBPC (glass passivated bridge rectifier in molded plastic case with integrated heatsink and isolated metal base; UL 94V-0 rated; mounting via #10 screw through central hole).

Pin/Terminal	Circuit Role	Design Meaning
AC1	AC Input Terminal	One of two alternating current inputs; connected internally to anode of D1 and cathode of D2 in full-wave bridge configuration.
AC2	AC Input Terminal	Second AC input; connected internally to cathode of D1 and anode of D2 - forms center-tapped input pair.

−	DC Output Cathode	Negative DC output node; common anode connection of D2 and D4 - serves as return path and system ground reference.
Case	Electrically Isolated Heatsink Interface	Metal base is insulated from all terminals (1500V isolation); must be mounted to external heatsink for thermal management.

Key Features

Feature	Design Value

UL Recognized (E94661)	Fulfills safety certification requirements for end-equipment compliance in North American industrial power supplies.
RoHS-compliant finish	Lead-free silver-plated terminals meet EU Directive 2002/95/EC and support automated soldering processes.

Applications

Industrial Motor Drives

Uninterruptible Power Supplies

Use Scenario: AC line rectification feeding DC bus for 3-phase IGBT inverters in HVAC compressors and conveyor systems.

IC Role / Device Role / Timing Role: Bridge rectifier converting 230VAC single-phase input to ~325VDC bus; operates continuously at 12–15A with forced-air cooling.

Use Value: 5.0°C/W RθJC and 300A IFSM ensure robust startup under locked-rotor conditions and sustained thermal stability during overload.

Use Scenario: Mains-powered battery charger and inverter stage in offline UPS units with dual-mode operation (line-interactive and double-conversion).

IC Role / Device Role / Timing Role: Primary AC/DC conversion stage delivering regulated DC to battery charging circuitry and inverter H-bridge; handles 15A peak load currents.

Use Value: Low 1.1V VFM minimizes conduction loss during extended backup runtime, while 1500V isolation simplifies grounding architecture in dual-isolation designs.

Programmable Logic Controller Power

Industrial Lighting Ballasts

Use Scenario: Embedded 24VDC power supply within DIN-rail mounted PLC modules accepting universal 85–264VAC input.

IC Role / Device Role / Timing Role: Input-stage rectifier preceding PFC controller and buck converter; operates at partial load with high efficiency across wide input range.

Use Value: Glass passivation ensures <5μA IR at elevated temperatures, preserving no-load regulation and reducing standby power consumption.

Use Scenario: Electronic ballast for HID lamps in factory high-bay lighting, requiring high-voltage DC bus generation from 277VAC line.

IC Role / Device Role / Timing Role: Full-wave rectifier feeding resonant LLC converter operating at 200kHz; subjected to frequent hot-switching and thermal transients.

Use Value: 400V VRRM provides 30% margin over 277VAC RMS (392V peak), and 150°C max TJ rating sustains reliability in enclosed luminaires.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay GBU15J	Same 15A/400V rating but TO-220AB package; RθJC = 4.0°C/W; no integrated heatsink or case isolation.	Requires external insulating pad and separate heatsink; unsuitable for direct-chassis mounting.	Select when board space is constrained and discrete heatsink integration is preferred over modular mounting.
ON Semiconductor GBPC1504	Identical specifications and GBPC package; same pinout, thermal, and isolation ratings; manufactured under different fab process.	No functional difference; validated for drop-in replacement in legacy Diodes-designed systems.	Choose for supply chain diversification where Diodes' lead time exceeds 12 weeks.

Compared with GBU15J, GBPC1504 offers integrated isolation and simplified mechanical design at the cost of larger footprint; versus ON's GBPC1504, it provides identical performance but distinct traceability and qualification history for aerospace-qualified builds.

FAQ

What is the maximum allowable case temperature for continuous 15A operation?

The datasheet specifies 15A average output current at TC = 70°C. Exceeding this requires linear derating per Figure 1: at TC = 100°C, IO drops to ~9.5A. Sustained 15A operation demands active cooling or oversized heatsinking to maintain TC ≤ 70°C.

Can GBPC1504 be used with capacitive input filters without additional protection?

No. The datasheet explicitly requires 20% current derating for capacitive loads due to high inrush current. For 15A-rated use, limit to 12A with bulk capacitance; add NTC thermistors or active inrush limiters to prevent IFSM exceedance during cold start.

Is the metal case electrically connected to any internal terminal?

No. The metal base is fully isolated from all four terminals (AC1, AC2, +, −) with 1500V dielectric strength. This allows direct mounting to grounded heatsinks without shorting risk - confirmed by UL file E94661 and test Note 3.

Does the "W" suffix in GBPC1504W indicate a different electrical specification?

No. GBPC1504W uses wire leads instead of Faston terminals but shares identical electrical ratings, thermal performance, and isolation characteristics. Only mechanical termination differs; both versions have same VRRM, IO, IFSM, and RθJC values per the datasheet table.
