Diodes Incorporated DBF2510-13

Overview

DBF2510 from Diodes Incorporated is a glass passivated surface-mount bridge rectifier rated for 1000 V peak repetitive reverse voltage, 2.5 A average output current, and 80 A non-repetitive surge current. It performs full-wave AC-to-DC rectification in compact SMT power supplies and is optimized for LED lighting drivers and universal-input adapters.

For engineers reviewing the DBF2510 datasheet, DBF2510 pinout, DBF2510 application, or DBF2510 equivalent, key selection criteria include its 1.0 V max forward voltage at 2.5 A, 5 μA max leakage at 1000 V, 30 pF typical junction capacitance, thermal resistance of 7.8 °C/W (junction-to-case), and DBF package footprint compatibility with high-density PCB layouts.

Technical Context

This discrete bridge rectifier integrates four silicon diodes in a single DBF package with common-cathode and common-anode configuration. Its glass passivation ensures stable reverse characteristics across -55°C to +150°C operating range and supports reliable operation under capacitive-load derating (20% IO reduction).

The device delivers low conduction loss via 0.95 V typical VF at 2.5 A and maintains tight leakage control - ≤5 μA at 1000 V and 25°C, rising to ≤500 μA at 125°C - enabling stable DC bus generation in thermally constrained environments.

Key Specifications

Pinout & Package

Package: DBF - Molded plastic, UL 94V-0 rated, 8.5–8.9 mm × 6.45–6.85 mm body, 0.214 g weight, lead-free matte tin plating.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar bridge rectifier applications.

Compared with MSB25MH-13, DBF2510 offers wider junction temperature margin (+150°C vs. +125°C) but lacks AEC-Q101 certification; versus GBU6K, it saves >65% PCB area and enables automated placement, though with lower surge margin (80 A vs. 150 A).

Availability

DBF2510 is available at Aetrix Electronics and suitable for LED lighting drivers, universal-input adapters, and home appliance power supplies requiring stable component supply despite its obsolete status.

Supply support for DBF2510 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, with design, manufacturing, and sales operations across Asia, Europe, and North America.

The DBF2510 belongs to Diodes' high-voltage bridge rectifier product line, engineered for space-constrained, high-efficiency AC/DC conversion in consumer and industrial power supplies.

FAQ

Is DBF2510 still in production?

No - Diodes Incorporated has officially discontinued DBF2510 and marked it as obsolete. Aetrix Electronics maintains limited legacy stock for last-time buy and BOM continuity support, but new designs should migrate to MSB25MH-13 per the manufacturer's recommendation.

What is the thermal pad configuration for DBF2510?

The DBF2510 has no exposed thermal pad; heat dissipation occurs through its four soldered terminals. The recommended layout uses 30 mm × 30 mm 1 oz copper pads per pin to achieve the specified RθJC of 7.8 °C/W and sustain 2.5 A at TC = +110°C.

Can DBF2510 replace GBU6K in existing designs?

Electrically yes for 2.5 A applications, but mechanically no - DBF2510 uses surface-mount DBF packaging (8.7 × 6.6 mm), while GBU6K is through-hole (22.5 × 18.5 mm). PCB redesign and requalification are required due to footprint, thermal path, and surge rating differences (80 A vs. 150 A).

Does DBF2510 meet automotive qualification standards?

No - DBF2510 is not AEC-Q101 qualified. For automotive applications, Diodes recommends MSB25MH-13, which is AEC-Q101 qualified, PPAP-capable, and manufactured in IATF 16949 certified facilities, with identical electrical specs and DBF packaging.
