Taiwan Semiconductor Corporation ABS15J REG

Overview

ABS15J REG from Taiwan Semiconductor is a 1.5A, 600V standard bridge rectifier in ABS surface-mount package, featuring glass-passivated junctions, 40A non-repetitive surge capability, and J-STD-020 Level 1 moisture sensitivity - used in AC/DC front-end stages of compact SMPS and LED drivers.

For engineers reviewing the ABS15J REG datasheet, ABS15J REG pinout, ABS15J REG application, or ABS15J REG equivalent, key selection criteria include peak reverse voltage (600 V), forward current rating (1.5 A on FR-4), thermal resistance (R_θJA = 80 °C/W), and AEC-Q101 qualification status (non-H variant).

Technical Context

The ABS15J REG integrates four silicon diodes in a single-phase full-wave bridge configuration with quad-terminal layout. Its glass-passivated junction ensures stable reverse leakage (<5 µA at 25°C) and high-temperature operation up to 150°C junction temperature.

Designed for automated SMT assembly, it uses matte tin-plated leads compliant with J-STD-002 solderability and meets UL 94V-0 flammability requirements. Thermal performance is defined by R_θJL = 25 °C/W and R_θJA = 80 °C/W under standard JEDEC test conditions.

FAQ

What is the maximum junction temperature rating for ABS15J REG?

The ABS15J REG has a maximum junction temperature (T_J) rating of +150°C. This specification allows reliable operation in thermally demanding environments such as enclosed LED drivers or industrial power supplies. The device maintains stable reverse leakage and forward voltage characteristics across its full –55°C to +150°C junction range, as verified in TSC's E2103 datasheet revision.

Does ABS15J REG support automated SMT placement?

Yes, ABS15J REG is explicitly designed for automated placement, with gull-wing leads optimized for standard pick-and-place equipment and reflow soldering. Its ABS package meets J-STD-002 solderability requirements and carries J-STD-020 Level 1 moisture sensitivity - eliminating the need for baking prior to reflow. These features are confirmed in the "MECHANICAL DATA" and "ORDERING INFORMATION" sections of the ABS15J REG datasheet.

What is the forward voltage drop of ABS15J REG at rated current?

The ABS15J REG exhibits a maximum forward voltage drop (V_F) of 0.97 V per diode at 1.5 A and 25°C junction temperature, rising to 1.00 V under worst-case conditions. This value is measured under pulsed conditions (PW = 0.3 ms) and directly impacts conduction losses in the bridge. The typical V_F is 0.88 V at 0.5 A, confirming low-loss behavior across its operating range.

Is ABS15J REG RoHS and halogen-free compliant?

Yes, ABS15J REG is RoHS compliant and halogen-free per IEC 61249-2-21. These compliance statements are explicitly declared in the "FEATURES" section of the official Taiwan Semiconductor datasheet (Version E2103). The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated - satisfying both environmental and safety requirements for global end-product certifications.

How does ABS15J REG differ from ABS15JH?

ABS15J REG and ABS15JH share identical electrical parameters, package (ABS), and pinout. The sole difference is qualification: ABS15JH is AEC-Q101 qualified for automotive applications, while ABS15J REG is the standard industrial-grade variant. The "H" suffix in ABS15JH denotes AEC-Q101 compliance, as stated in the "ORDERING INFORMATION" table of the datasheet. No electrical or mechanical redesign distinguishes the two.
