Product details
Overview
GBPC1508W from Diodes Incorporated is a 15A glass passivated single-phase bridge rectifier with 800V peak repetitive reverse voltage (VRRM), 1.1V forward voltage at 7.5A per diode, and 300A non-repetitive surge rating - used in AC/DC power supplies for industrial motor drives and HVAC control systems.
For engineers reviewing the GBPC1508W datasheet, GBPC1508W pinout, GBPC1508W application, or GBPC1508W equivalent, key selection criteria include thermal resistance (5.0°C/W junction-to-case), case isolation voltage (1500V), and wire-lead mounting compatibility with #10 screw heatsink attachment.
Technical Context
This device integrates four silicon junction diodes in a single molded plastic package with internal heatsink, configured as a full-wave bridge to convert AC input (e.g., 560V RMS) into pulsating DC output. Its glass passivated die construction ensures low reverse leakage (5.0μA at 25°C) and stable operation up to +150°C junction temperature.
The GBPC1508W is rated for 15A average forward current at TC = 70°C when mounted on a 220 × 220 × 50 mm aluminum heatsink, with derating required for capacitive loads (−20% current). Total capacitance is 300pF at 1MHz and 4V reverse bias, supporting moderate-frequency switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Maximum peak reverse voltage the bridge withstands without breakdown; defines usable AC input range (≤560V RMS). |
| IO @ TC=70°C | 15 A - Continuous DC output current capability when case temperature is held at 70°C via heatsinking. |
| VFM @ IF=7.5A | 1.1 V - Forward voltage drop per diode leg; determines conduction loss (≈16.5W total at full load). |
| IFSM | 300 A - Single half-sine surge rating (8.3ms); supports inrush current handling in transformer-coupled supplies. |
| RθJC | 5.0 °C/W - Thermal resistance from junction to case; requires ≥100 cm² heatsink area for safe 15A operation. |
| IR @ 25°C | 5.0 μA - Reverse leakage per diode; enables low standby power in offline SMPS front-ends. |
| Case Isolation | 1500 V - Dielectric strength between metal base and terminals; satisfies reinforced insulation requirements. |
Pinout & Package
Package: GBPC-W - Molded plastic case with internally mounted heatsink and wire leads (no Faston terminals); UL 94V-0 rated; weight ≈14 g; mounting via #10 screw through central hole (5.08–5.59 mm diameter).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 / AC2 | AC Input Terminals | Accept bidirectional AC line input; electrically symmetric; no polarity sensitivity. |
| + | Positive DC Output | Full-wave rectified anode-side output node; connects to bulk capacitor positive terminal. |
| − | Negative DC Output | Full-wave rectified cathode-side return path; ties to bulk capacitor negative and system ground reference. |
| Metal Base | Thermal & Electrical Reference | Electrically isolated (1500V) metal heatsink surface; must be grounded or floated per safety design. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enables stable 5.0μA reverse leakage at 25°C and 500μA at 125°C - critical for high-temp reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU15J (ON Semiconductor) | Same 15A/800V rating but GBU package (lower RθJC = 3.5°C/W); no case isolation voltage specified. | Requires external insulating pad for grounded heatsink mounting; better thermal performance in space-constrained layouts. | Select when thermal budget is tighter and isolation can be managed externally. |
| KBP1508 (Comchip) | Identical electrical specs and GBPC-W footprint; RoHS compliant but not UL recognized (E94661). | Not suitable for end-equipment requiring UL Component Recognition; acceptable for internal PCB-level designs. | Select for cost-sensitive industrial OEMs where UL listing is not mandated. |
Compared with GBU15J and KBP1508, the GBPC1508W uniquely combines UL recognition, 1500V case isolation, and wire-lead mechanical compatibility - making it preferred for safety-certified, heatsink-mounted AC/DC front-ends.

FAQ
What is the maximum heatsink temperature allowed for continuous 15A operation?
The GBPC1508W delivers 15A average forward current only when case temperature (TC) is maintained at ≤70°C. With RθJC = 5.0°C/W, a 70°C case requires ≤350°C·W junction-to-ambient delta - meaning ambient + heatsink rise must stay below 70°C. Derating curves show 10A at TC = 100°C.
Can GBPC1508W be mounted directly to a grounded metal chassis?
Yes - its 1500V case-to-terminal isolation voltage permits direct screw-mounting to grounded heatsinks without insulating hardware, provided creepage/clearance distances meet IEC 60950-1 or IEC 62368-1 requirements for the end application's pollution degree and overvoltage category.
How does the "W" suffix affect mechanical installation?
The "W" suffix denotes wire leads instead of Faston terminals. It enables secure #10 screw mounting through the central hole (5.08–5.59 mm), with torque limited to 8.0 inch-pounds. Wire leads allow flexible routing and soldering to PCBs or terminal blocks, unlike Faston-style snap-in connections.
Is GBPC1508W suitable for capacitive-input filter applications?
No - the datasheet explicitly requires 20% derating of IO for capacitive loads due to higher peak currents and thermal stress. For such designs, select a higher-current variant (e.g., GBPC2508W) or implement inrush limiting to avoid exceeding junction temperature limits during cold-start conditions.
