Diodes Incorporated ABS10B-13

Overview

ABS10B-13 from Diodes Incorporated is a 1.5A, 1000V glass passivated surface-mount bridge rectifier in SOPA-4 package, featuring 1.1V max forward voltage at 1.5A and 5μA reverse leakage at 1000V/25°C. It delivers full-wave AC-to-DC conversion for compact power supplies in LED lighting, AC adapters, and battery chargers.

For engineers reviewing the ABS10B-13 datasheet, ABS10B-13 pinout, ABS10B-13 application, or ABS10B-13 equivalent, this device supports high-reliability SMT assembly with RoHS-compliant matte tin plating, UL 94V-0 molded plastic housing, and validated thermal resistance of 62.5°C/W (J-A) on standard FR-4 PCBs.

Technical Context

This bridge rectifier integrates four silicon diodes in a single SOPA-4 package with internal configuration matching standard full-wave bridge topology (+AC, –AC, +DC, –DC). Its glass passivated die construction ensures stable reverse blocking up to 1000V V_RRM and low thermal resistance (25°C/W J-L) for efficient heat transfer to PCB copper pads.

Designed for operation across –55°C to +150°C, it sustains 50A non-repetitive surge current (8.3ms half-sine) and exhibits 17pF typical junction capacitance per leg at 4V reverse bias - critical for EMI control in high-frequency SMPS designs.

Key Specifications

Pinout & Package

FAQ

What is the maximum allowable PCB copper pad size for ABS10B-13 to achieve the published R_θJA of 62.5°C/W?

The datasheet specifies that the 62.5°C/W thermal resistance is measured on FR-4 with a 0.56" × 0.73" (14.2mm × 18.5mm) copper pad per terminal. Using smaller pads increases thermal resistance; larger pads improve dissipation but require verification against solder joint reliability and IPC-7351B land pattern guidelines.

Can ABS10B-13 be used in a center-tapped transformer full-wave rectifier configuration?

No - ABS10B-13 is a monolithic bridge rectifier with fixed internal interconnects (+AC, –AC, +DC, –DC). It is designed exclusively for standard bridge configurations. A center-tapped design requires two separate diodes and cannot utilize this integrated bridge topology.

Does the 5μA IR specification apply to each diode junction or the entire bridge?

The 5μA reverse leakage (IR) is specified per diode element - meaning each of the four internal diodes exhibits ≤5μA at 1000V and +25°C. Total bridge leakage is not tested or guaranteed, as internal connections prevent independent measurement of all junctions simultaneously.

Is ABS10B-13 suitable for use in Class II (double-insulated) power supplies?

Yes - its 1000V V_RRM, UL 94V-0 package, and reinforced creepage/clearance in SOPA-4 layout meet basic insulation requirements for Class II designs. However, final system-level certification requires validation of PCB layout, spacing, and enclosure compliance per IEC 62368-1.
