Product details
Overview
MSB15MH-13 from Diodes Incorporated is a 1.5A surface-mount standard recovery bridge rectifier with 1000V peak repetitive reverse voltage (VRRM), 1.1V max forward voltage at 1.5A/25°C, and 5μA max reverse leakage at 1000V/25°C; used in AC-DC full-wave rectification for LED lighting drivers and compact AC adapters.
For engineers reviewing the MSB15MH-13 datasheet, MSB15MH-13 pinout, MSB15MH-13 application, or MSB15MH-13 equivalent, this device supports high-voltage, low-profile SMT power conversion where thermal resistance (RθJC = 10°C/W) and UL recognition (E364304) are critical for safety-compliant designs.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a monolithic MSBL package, configured for standard recovery operation (trr not specified but consistent with standard-recovery classification). It operates across -55°C to +150°C junction temperature and supports 70A non-repetitive surge (8.3ms) and 140A (1.0ms).
Designed for resistive/inductive loads at 60Hz, it requires 20% current derating under capacitive loading. Its glass-passivated die construction ensures robustness against moisture and mechanical stress during reflow soldering and long-term operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands peak reverse voltage up to 1000V without breakdown, enabling use in 700VRMS AC line applications. |
| IO | 1.5 A - Continuous average rectified output current at TC = +110°C, defining maximum steady-state power handling. |
| VF | 1.1 V max @ 1.5A/25°C - Forward voltage drop directly impacts conduction loss and thermal rise in compact power supplies. |
| IR | 5 μA max @ 1000V/25°C - Low leakage preserves efficiency in high-impedance hold-up or standby circuits. |
| RθJC | 10 °C/W - Junction-to-case thermal resistance enables direct heatsinking via PCB copper pads for thermal management. |
| IFSM | 70 A @ 8.3ms - Surge rating determines survivability during cold-start inrush into bulk capacitors. |
| CT | 25 pF @ 4V/1MHz - Junction capacitance affects high-frequency noise coupling and EMI filter design. |

Applications
| LED Lighting Driver | Compact AC Adapter |
|---|---|
Use Scenario: Rectifying 120/230V AC mains into DC for constant-current LED driver ICs in downlights and panel lights. IC Role / Device Role / Timing Role: Full-wave bridge rectifier providing unidirectional DC bus prior to PFC or buck converter stage.

Use Value: Glass passivation and -55°C to +150°C operating range support reliable operation in thermally demanding office environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU4K-TP (Good-Ark) | Same 1000V VRRM, 1.5A IO, but larger GBU package (10.5 × 14.2 mm vs. MSBL's 6.6 × 7.3 mm); RθJA = 45°C/W. | Requires more PCB area and offers lower power density; suitable where thermal mass compensates for higher RθJA. | Select when footprint flexibility exists and legacy GBU layout reuse is prioritized over miniaturization. |
| MB15M (ON Semiconductor) | Identical electrical specs (1000V/1.5A), same MSBL package, but lacks UL recognition and has higher IR (10μA vs. 5μA). | Acceptable for non-safety-certified industrial controls, but not for UL-marked consumer products requiring leakage compliance. | Choose only for cost-sensitive, non-certified applications where UL file #E364304 is not required. |
Compared with GBU4K-TP and MB15M, MSB15MH-13 uniquely combines UL recognition, tighter leakage control, and minimal MSBL footprint-making it optimal for certified, space-constrained AC-DC designs where regulatory compliance and thermal performance are jointly critical.

FAQ
What is the maximum operating temperature for MSB15MH-13?
The MSB15MH-13 has a specified junction temperature range of -55°C to +150°C. Its thermal resistance values (RθJC = 10°C/W, RθJA = 50°C/W) mean that at 1.5A load and 25°C ambient, junction temperature rises approximately 75°C above ambient-well within safe limits if PCB copper area meets recommended pad layout guidelines.
Is MSB15MH-13 suitable for automotive applications?
No-MSB15MH-13 is not AEC-Q200 qualified and is not rated for automotive use. Diodes explicitly states that automotive-grade variants require specific change control, PPAP capability, and IATF 16949 manufacturing; this part is intended for commercial/industrial AC-DC power supplies only.
Does MSB15MH-13 have a built-in thermal shutdown feature?
No-MSB15MH-13 is a passive silicon bridge rectifier with no active circuitry or thermal protection. Thermal management relies entirely on external PCB layout, copper area, and system-level airflow or heatsinking per the datasheet's RθJC and RθJA specifications.
How does the MSBL package differ from common bridge packages like KBP or GBU?
The MSBL package measures 6.6 × 7.3 × 1.4 mm-significantly smaller than KBP (13.5 × 18.5 mm) and GBU (10.5 × 14.2 mm). Its compact size, low profile, and lead-free matte tin plating are optimized for high-density SMT assembly, whereas KBP/GBU packages prioritize higher current ratings and manual through-hole compatibility.
