Diodes Incorporated MB10S-13

Overview

MB10S-13 from Diodes Incorporated is a glass passivated single-phase bridge rectifier in MBS package, rated for 1000 V peak repetitive reverse voltage, 0.8 A average output current at +40°C, and 1.1 V typical forward voltage per diode at 0.8 A. It delivers low leakage (≤5 μA at 1000 V, 25°C) and supports AC–DC conversion in compact LED drivers and wall adapters.

For engineers reviewing the MB10S-13 datasheet, MB10S-13 pinout, MB10S-13 application, or MB10S-13 equivalent, this page provides verified thermal resistance (R_θJA = 101 °C/W), surge rating (I_FSM = 30 A), capacitance (C_T = 8 pF), polarity marking, and RoHS-compliant lead-free plating details critical for layout, reliability, and compliance validation.

Technical Context

This bridge rectifier integrates four silicon diodes in a single-phase full-wave configuration with common-cathode and common-anode terminals. Its glass passivation ensures stable reverse characteristics across –55°C to +150°C operating range and enables reliable operation under transient overvoltage conditions up to 1000 V.

The MBS package uses molded plastic (UL 94V-0), matte tin-plated terminals solderable per MIL-STD-202 Method 208, and supports automated SMT assembly. Thermal performance is defined per element: R_θJL = 42 °C/W and R_θJA = 101 °C/W on specified FR-4 PCB pads.

FAQ

What is the maximum ambient temperature for continuous 0.8 A operation?

The MB10S-13 delivers 0.8 A average output current only when mounted on the specified FR-4 PCB (0.4"×0.5", 2 oz copper) at TA ≤ +40°C. At higher ambient temperatures, derating is required per Figure 1; at +85°C, the usable current drops to approximately 0.5 A.

How is polarity identified on the MB10S-13 package?

Polarity is marked directly on the device body: "+" denotes the common cathode (DC+) terminal, "–" denotes the common anode (DC–) terminal, and "~" symbols identify the two AC input pins. The internal schematic shows these markings aligned with the top-view pin diagram in the datasheet.

Does MB10S-13 meet IPC/JEDEC J-STD-020 moisture sensitivity requirements?

Yes - the MB10S-13 is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/85% RH and requires no baking prior to standard SMT reflow, simplifying factory handling and assembly.

Can MB10S-13 replace MB6S or GBU2K in existing designs?

No - MB10S-13 (MBS, 0.8 A) has lower current rating and different package dimensions than MB6S (MBF, 0.6 A) and GBU2K (GBU, 2 A). Direct replacement requires verification of thermal margin, PCB pad layout, and surge capability; consult Diodes' cross-reference tool for validated alternatives.
