Diodes Incorporated MB10F-13

Overview

MB10F-13 from Diodes Incorporated is a surface-mount standard recovery bridge rectifier configured as a single-phase full-wave AC/DC converter, rated for 1000 V peak repetitive reverse voltage, 0.8 A average output current at +110°C, and 1.1 V forward voltage per diode at 0.8 A. It employs glass-passivated die construction in an MBF package and is used in LED lighting power supplies and AC adapters.

For engineers reviewing the MB10F-13 datasheet, MB10F-13 pinout, MB10F-13 application, or MB10F-13 equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (63 °C/W junction-to-ambient), low forward voltage drop, RoHS-compliant lead-free plating, and UL recognition (File # E364304).

Technical Context

The MB10F-13 integrates four standard-recovery silicon diodes in a single-phase bridge configuration with common-cathode and common-anode terminals. Its internal schematic defines AC input terminals (A1, A2) and DC output terminals (+, −), enabling full-wave rectification without external interconnection.

Designed for non-switching, line-frequency applications, it exhibits 8 pF typical junction capacitance per element at 4 V reverse bias and 1.0 MHz, and supports surge currents up to 30 A (8.3 ms half-sine) with an I²t rating of 3.74 A²s.

FAQ

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

The MB10F-13 delivers 0.8 A average output current at +110°C ambient when mounted on a specified FR-4 board (1"×1", 2 oz copper, 0.56"×0.73" pad). At +125°C, the rated current drops to 0.5 A due to thermal derating per Figure 1 in DS39046.

Is MB10F-13 suitable for high-frequency switching applications?

No. The MB10F-13 uses standard-recovery diodes with no specified reverse recovery time (t_rr) and is intended for 50/60 Hz line-frequency rectification only. It is not recommended for use in high-frequency SMPS where fast or ultrafast recovery is required.

Does MB10F-13 meet automotive qualification standards?

No. The MB10F-13 is not AEC-Q101 qualified. Diodes Incorporated explicitly states that automotive-grade parts require separate change control, PPAP capability, and IATF 16949 manufacturing - none of which apply to this standard commercial-grade device.

How is polarity marked on the MB10F-13 package?

Polarity is marked on the top surface of the MBF package: the cathode (+) terminal is indicated by a distinct "+" symbol adjacent to the corresponding pin, and the AC inputs (A1/A2) are identified by orientation relative to the marking bar and date code. Pin 1 (A1) is located at the left end when the marking side faces up and the notch/bar is oriented left-to-right.
