Product details
Overview
MSB22ML from Diodes Incorporated is a surface-mount standard recovery bridge rectifier rated for 1000 V repetitive peak reverse voltage, 2.2 A average forward current at 110°C with heatsink, and 0.92 V maximum forward voltage at 1.1 A and 25°C. It features glass-passivated die construction, UL 94V-0 plastic package (MSBL), and is designed for AC–DC full-wave rectification in SMPS, LED lighting drivers, and battery chargers.
For engineers reviewing the MSB22ML datasheet, MSB22ML pinout, MSB22ML application, or MSB22ML equivalent, key selection criteria include its 1000 V PRV rating, low VF at elevated temperature (0.81 V @ 2.2 A, 125°C), thermal resistance of 10°C/W junction-to-case, compact MSBL footprint, and compliance with RoHS, halogen-free, and antimony-free "Green" requirements.
Technical Context
This bridge rectifier integrates four standard recovery diodes in a single MSBL package with internal full-wave configuration. Its glass-passivated junction ensures stable leakage performance up to 125°C (IR ≤ 500 µA @ 1000 V), and it supports non-repetitive surge currents up to 180 A (1 ms) at 25°C.
The device is optimized for SMT assembly with matte tin-plated leads and meets J-STD-020 moisture sensitivity Level 1. Thermal design relies on its 10°C/W RθJC, enabling reliable operation at TJ = –55°C to +150°C when mounted on a 20×20 mm, 1 oz/ft² copper pad per pin.
Key Specifications

| VF Max | 0.92 V @ IF = 1.1 A, TJ = +25°C - Low conduction loss improves efficiency in high-frequency rectification stages |
| IR Max | 5 µA @ VR = 1000 V, TJ = +25°C - Minimal leakage preserves regulation in high-impedance hold-up circuits |
| RθJC | 10 °C/W - Enables direct thermal path to heatsink or PCB copper, critical for power density scaling |
| CJ Typ | 35 pF @ 1 MHz, 4 V - Low junction capacitance minimizes switching noise and EMI in fast-switching converters |
| IFS M (1 ms) | 180 A @ TJ = +25°C - Handles inrush surges during cold-start of offline adapters and LED drivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU4K | Higher VF (1.05 V @ 2 A), larger GBU package (10.3 × 14.2 mm), RθJA ≈ 40°C/W | Better suited for through-hole prototyping or lower-frequency (<100 kHz) designs with ample board area | Select when manual assembly, higher surge margin (120 A @ 8.3 ms), or legacy footprint compatibility is required |
| MB10F | Lower VRRM (1000 V same), but IF(AV) = 1.0 A only; smaller MBF package (6.2 × 4.2 mm); VF = 1.1 V @ 1 A | Targeted for low-power auxiliary supplies or signal-level rectification, not main DC bus generation | Choose only for sub-1 W bias rails where size is critical and current demand is ≤1 A |
Compared with GBU4K and MB10F, MSB22ML uniquely balances high current (2.2 A), low VF (0.92 V), ultra-compact MSBL footprint, and industry-leading thermal resistance (10°C/W), making it optimal for modern SMT-based, high-efficiency, space-constrained AC–DC converters.

FAQ
What is the maximum junction temperature and how does it affect derating?
The MSB22ML has a rated operating junction temperature range of –55°C to +150°C. Its average forward current must be derated linearly above +110°C case temperature, reaching zero at +150°C, as shown in Figure 1 of DS43667. This requires thermal design using its 10°C/W RθJC and proper copper pad sizing to maintain safe TJ under load.
Is MSB22ML suitable for automotive applications?
No - MSB22ML is not AEC-Q101 qualified and is not intended for automotive use. Diodes states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing; users must contact Diodes directly for qualified alternatives such as the ABS210Q or GBU6K-A.
How does the MSBL package compare to traditional bridge packages like KBP or GBU?
The MSBL package measures 7.30 × 6.60 × 1.40 mm - significantly smaller and thinner than KBP (13.5 × 11.2 × 3.5 mm) or GBU (14.2 × 10.3 × 3.5 mm). Its low profile enables use in slim-profile adapters and LED drivers, while its 10°C/W RθJC exceeds typical KBP values (~15°C/W), improving thermal headroom despite reduced volume.
What is the significance of the "Green" and halogen-free designation?
"Green" means MSB22ML contains <900 ppm bromine, <900 ppm chlorine (≤1500 ppm total Br+Cl), and <1000 ppm antimony compounds - exceeding RoHS 3 requirements. This eliminates corrosive halogen emissions during PCB reflow and end-of-life incineration, supporting sustainability goals and regulatory compliance in EU, Japan, and China markets.
