Product details
Overview
MSB25MH-13 from Diodes Incorporated is a 2.5A surface-mount standard recovery bridge rectifier in MSBL package, rated for 1000V peak repetitive reverse voltage, 1.1V max forward voltage at 2.5A/25°C, and 5µA max reverse leakage at 1000V/25°C; used in AC–DC full-wave rectification for LED lighting drivers and SMPS input stages.
For engineers reviewing the MSB25MH-13 datasheet, MSB25MH-13 pinout, MSB25MH-13 application, or MSB25MH-13 equivalent, key selection criteria include PRV rating, thermal resistance (RθJC = 7.8°C/W), surge current capability (160A @ 1ms), RoHS/Green compliance, and UL recognition (E364304).
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a compact MSBL molded plastic package with glass-passivated die construction. It supports standard recovery operation (trr not specified, confirming non-fast/ultrafast classification) and is optimized for line-frequency (50/60Hz) rectification under resistive or inductive loads.
Thermal design relies on low junction-to-case resistance (7.8°C/W) and compatibility with SMT reflow profiles. Polarity is marked on body; terminals use matte tin plating, solderable per MIL-STD-202 Method 208, and moisture sensitivity level is J-STD-020 Level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands peak reverse voltage up to 1000V without breakdown, suitable for 700V RMS AC inputs. |
| IF(AV) | 2.5 A - Continuous average output current at TC = +110°C, defining steady-state power handling in heatsink-limited designs. |
| VF | 1.1 V max @ 2.5A/25°C - Forward voltage drop directly impacts conduction loss and thermal rise in bridge configuration. |
| IR | 5 µA max @ 1000V/25°C - Low leakage ensures minimal standby power loss and stable DC bus hold-up in off-state. |
| IFSM | 160 A @ 1ms - Peak surge rating determines robustness against inrush currents during cold-start of capacitive-input SMPS. |
| RθJC | 7.8 °C/W - Enables direct thermal path to PCB copper or heatsink, critical for maintaining TJ ≤ 150°C under full load. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard recovery bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU2K-E3/54 (Vishay) | Same 1000V VRRM, 2.0A IF(AV), higher VF (1.1V @ 2A), larger GBU package (10.5×14.2mm vs. MSBL 6.6×7.3mm). | Less suited for ultra-thin LED drivers due to 4.2mm height vs. MSBL's 1.4mm profile. | Select when board space permits larger footprint and higher surge margin (100A IFSM) is prioritized over thickness. |
| GBU4K (ON Semiconductor) | 1000V VRRM, 4.0A IF(AV), VF = 1.1V @ 4A, same GBU package, no UL recognition. | Over-specified current rating increases cost and thermal mass unnecessarily in 2.5A designs. | Choose only if future-proofing for higher-power revisions is required and UL listing is not mandatory. |
Compared with GBU2K-E3/54 and GBU4K, MSB25MH-13 offers optimal balance of thin-profile packaging, UL recognition, and precise 2.5A rating-reducing board area by 58% versus GBU packages while maintaining full safety compliance and thermal performance for mainstream LED and adapter applications.

FAQ
What is the maximum operating temperature for MSB25MH-13?
The MSB25MH-13 has an operating junction temperature range of –55°C to +150°C. Its 2.5A average current rating is specified at TC = +110°C, meaning the case must be maintained at or below this temperature under continuous load. Thermal design must ensure junction temperature stays within limits using RθJC = 7.8°C/W and appropriate PCB copper area or heatsinking.
Is MSB25MH-13 suitable for capacitive-input filter designs?
Yes, but with 20% current derating per datasheet guidance. At full 2.5A rating, it supports resistive or inductive loads; for capacitive-input SMPS, maximum continuous current drops to 2.0A to manage increased RMS current and thermal stress caused by high crest-factor waveforms.
Does MSB25MH-13 meet automotive qualification standards?
No - MSB25MH-13 is not AEC-Q101 qualified. While Diodes offers automotive-grade variants (e.g., MSB25MHQ-13), this standard version lacks PPAP documentation, IATF 16949-specific process controls, and extended temperature validation required for automotive applications.
How is polarity identified on the MSB25MH-13 package?
Polarity is marked on the top surface of the MSBL package: a beveled edge or notch indicates Pin 1 location. The internal schematic shows Pin 1 as one AC input terminal; Pin 2 is DC negative, Pin 3 is the second AC input, and Pin 4 is DC positive - consistent with standard bridge rectifier pinout orientation.
