Product details
Overview
MB152W from Diodes Incorporated is a high-current silicon bridge rectifier with wire leads (suffix "W"), rated for 200 V peak reverse voltage (VRRM), 15 A average output current at TC = 55°C, and 1.1 V forward voltage drop at 7.5 A. It features a metal case for superior thermal dissipation, UL 94V-0 flammability rating, and RoHS-compliant lead-free finish (date code 0514+). It is used in industrial AC/DC power supplies requiring robust, bolt-down heat-sink mounting.
For engineers reviewing the MB152W datasheet, MB152W pinout, MB152W application, or MB152W equivalent, key selection criteria include its 200 V VRRM rating, 15 A I(AV) at 55°C case temperature, thermal resistance RJC = 2.5 °C/W, wire-lead mechanical configuration, and compatibility with 60 Hz resistive/inductive loads.
Technical Context
This single-phase full-wave bridge rectifier integrates four silicon diodes in a compact metal-case package optimized for high-power linear and transformer-based AC/DC conversion. Its design supports bolt-down mounting with silicone thermal compound to achieve low junction-to-ambient thermal resistance - critical for sustained 15 A operation under industrial ambient conditions.
The device operates across –55°C to +150°C junction temperature range and exhibits low reverse leakage (10 µA at 25°C, 1.0 mA at 100°C) and high surge tolerance (300 A IFSM, 8.3 ms half-sine). Its wire-lead terminals comply with MIL-STD-202 Method 208 solderability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum peak reverse voltage per element; defines safe AC input voltage limit (e.g., ≤141 V RMS). |
| I(AV) | 15.0 A at TC = 55°C - Continuous DC output current capability when case is actively cooled to 55°C. |
| VF | 1.1 V at 7.5 A - Forward voltage drop per diode pair; determines conduction loss (≈8.3 W total at full load). |
| IFSM | 300 A (8.3 ms) - Non-repetitive surge current rating; withstands inrush into capacitive or motor loads. |
| RJC | 2.5 °C/W - Junction-to-case thermal resistance; enables direct heat-sink coupling for thermal management. |
| IR | 10 µA at 25°C - Reverse leakage per element; ensures minimal standby power loss in high-impedance circuits. |
| TJ Range | –55°C to +150°C - Operating junction temperature range; supports deployment in harsh industrial environments. |
Pinout & Package
MB152W uses a 4-terminal metal-case package with wire leads (suffix "W") and universal mounting: two AC input terminals (marked ~), one positive DC output (+), and one negative DC output (–). The case serves as a thermal path, not an electrical terminal. Mounting requires #10 screw, 20 in·lb torque, and silicone thermal compound between case and heat-sink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 / AC2 | AC Input (Bridge AC Terminals) | Accept full-wave AC input; internally connected to opposite diode anodes/cathodes to form bridge topology. |
| (+) | Positive DC Output | Full-wave rectified positive output node; connects to bulk capacitor or regulator input. |
| (–) | Negative DC Output / Common Return | DC return path and reference node; electrically isolated from case unless externally bonded. |
Key Features
| Feature | Design Value |
|---|---|
| High-Conductivity Metal Case | Enables direct bolt-down thermal interface with heat-sink; reduces thermal impedance vs. plastic-packaged bridges. |
| UL 94V-0 Flame-Retardant Case | Meets stringent fire-safety requirements for enclosed industrial power equipment. |
| Wire-Lead Terminals (W suffix) | Supports flexible PCB-less interconnection, chassis wiring, or terminal block integration without solder pads. |
| RoHS-Compliant Lead-Free Finish | Complies with EU Directive 2002/95/EC (exemptions applied); suitable for environmentally regulated production. |
| Low RJC (2.5 °C/W) | Allows higher continuous current at elevated ambient temperatures when mounted on adequate heat-sink area. |
Applications
| Industrial AC/DC Power Supply | Motor Drive Front-End Rectification |
|---|---|
Use Scenario: Transformer-coupled 60 Hz AC input feeding unregulated DC bus in factory automation power modules. IC Role / Device Role / Timing Role: Full-wave bridge rectifier converting AC line to pulsating DC; no timing function. Use Value: Delivers 15 A average DC output with <1.1 V conduction loss per diode pair, minimizing heat generation in space-constrained enclosures. | Use Scenario: Rectifying AC from variable-frequency drive (VFD) transformer secondary before DC link capacitor. IC Role / Device Role / Timing Role: High-current passive rectifier; handles repetitive 300 A surges during motor startup. Use Value: Withstands 300 A non-repetitive surge (8.3 ms) and maintains <10 µA leakage at 25°C, ensuring stable DC link voltage under transient load. |
| Test Equipment Power Stage | Welding Power Supply Input Stage |
Use Scenario: Benchtop programmable DC power supply with adjustable output up to 30 V / 20 A. IC Role / Device Role / Timing Role: Primary rectification stage feeding linear regulation or switching pre-regulator. Use Value: Metal-case thermal design sustains 15 A output at 55°C case temperature, enabling compact, fanless front-end architecture. | Use Scenario: Heavy-duty arc welding machine converting 240 V AC mains to high-current DC for electrode output. IC Role / Device Role / Timing Role: Main-line rectifier handling intermittent 100% duty-cycle pulses with high peak current. Use Value: 200 V VRRM rating safely accommodates 240 V AC input with margin; 2.5 °C/W RJC allows efficient heat transfer to large aluminum chassis. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBPC1502 | Same 200 V VRRM and 15 A I(AV), but in GBPC plastic package with PCB-mount pins instead of wire leads. | Designed for automated PCB assembly; lacks metal-case thermal mass and bolt-down mounting. | Select if board-level integration and reflow compatibility are required over field-wiring flexibility. |
| KBPC1502 | Identical electrical ratings (200 V, 15 A), but uses standard KBPC metal case with Faston terminals instead of wire leads. | Requires terminal block or Faston crimp connection; no direct wire termination option. | Choose when legacy Faston infrastructure exists and thermal performance must match MB152W's RJC. |
Compared with MB152W, GBPC1502 trades wire-lead serviceability and metal-case thermal coupling for SMT manufacturability, while KBPC1502 retains metal-case cooling but replaces wire leads with standardized Faston terminals - both require layout or mechanical redesign for drop-in replacement.

FAQ
Is MB152W RoHS compliant?
Yes, MB152W is RoHS compliant per EU Directive 2002/95/EC with lead-free finish effective from date code 0514+. Exemptions for glass and high-temperature solder apply as specified in Annex Notes 5 and 7 of the directive.
What is the recommended mounting method for MB152W?
MB152W must be bolted directly to a heat-sink using a #10 screw at maximum 20 in·lb torque, with silicone thermal compound applied between the metal case and heat-sink surface to minimize thermal resistance and ensure reliable 15 A operation.
Can MB152W replace MB152 in an existing design?
Yes - MB152W is the wire-lead variant of MB152 (which uses Faston terminals). Both share identical electrical specifications, thermal resistance, and case dimensions; only the termination method differs, requiring wiring harness adaptation instead of terminal block connection.
Why is MB152W marked "Not Recommended for New Design"?
Diodes Incorporated recommends the newer GBPC15 series for new designs due to improved manufacturing consistency, wider availability, and enhanced surge robustness. MB152W remains fully supported for legacy repair and continuity, with no imminent obsolescence announced.
