Taiwan Semiconductor Corporation ABS6 REG

Overview

ABS6 REG from Taiwan Semiconductor is a 1A, 600V standard bridge rectifier in ABS surface-mount package, featuring glass-passivated junctions, 30A peak surge current capability, and AEC-Q101 qualification option (ABS6H). It serves as the AC-to-DC input stage in compact offline power supplies for consumer adapters and LED drivers.

For engineers reviewing the ABS6 REG datasheet, ABS6 REG pinout, ABS6 REG application, or ABS6 REG equivalent, key selection criteria include repetitive peak reverse voltage (600 V), forward current rating (1.0 A on aluminum substrate), thermal resistance (R_θJL = 25 °C/W), and RoHS/halogen-free compliance per IEC 61249-2-21.

Technical Context

The ABS6 REG integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode and common-anode terminals. Its glass-passivated junction ensures stable reverse leakage (<10 µA at 25°C, <150 µA at 125°C) and high reliability under thermal cycling.

Designed for automated SMT placement, it uses matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. The ABS molded plastic case meets UL 94V-0 and moisture sensitivity level 1 per J-STD-020.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving global industrial, consumer, and automotive markets since 1979.

The ABS series was developed specifically for high-reliability, surface-mount AC/DC front-end rectification in space-constrained power converters-emphasizing surge robustness, thermal efficiency, and process consistency for automated manufacturing.

FAQ

What is the maximum ambient temperature at which ABS6 REG can operate continuously at 1.0 A forward current?

ABS6 REG supports continuous 1.0 A forward current when mounted on an aluminum substrate up to +70°C ambient, based on its R_θJA = 80 °C/W and T_Jmax = 150°C. At higher ambient temperatures, derating is required per the forward current derating curve in TSC's ABS2–ABS10 datasheet (Version M2103). For reliable operation above 70°C, thermal simulation or empirical testing with actual PCB layout is recommended for ABS6 REG.

Does ABS6 REG have a halogen-free designation, and is it documented in the material declaration?

Yes, ABS6 REG is halogen-free in accordance with IEC 61249-2-21, and this compliance is explicitly stated in the official Taiwan Semiconductor ABS2–ABS10 datasheet (Version M2103, Page 1). The halogen-free status applies to the molding compound and internal materials, and full material declarations are available upon request from TSC for ABS6 REG.

Is ABS6 REG pin-compatible with ABS6H, and what is the functional difference between them?

ABS6 REG and ABS6H share identical ABS package dimensions, pinout, and electrical specifications-including V_RRM = 600 V, I_F = 1.0 A, and I_FSM = 30 A. The sole functional difference is that ABS6H undergoes full AEC-Q101 qualification (including HTSL, TC, HTRB), while ABS6 REG is the standard industrial-grade version. Both are mechanically and electrically interchangeable in the same footprint.

What is the typical forward voltage drop of ABS6 REG at 0.5 A and 100°C junction temperature?

The datasheet specifies V_F ≤ 0.95 V per diode at I_F = 0.4 A and T_J = 25°C. While no exact value is given at 0.5 A and 100°C, typical V_F increases ~2 mV/°C and ~0.15 V per 0.5 A increment. Thus, ABS6 REG exhibits approximately 1.05–1.10 V total bridge drop (2× diode drop) under those conditions-verified by extrapolation from Figure 4 (Typical Forward Characteristics) in the ABS2–ABS10 datasheet.

Can ABS6 REG be used in place of ABS4 REG in a design originally specified for 400 V reverse voltage?

Yes, ABS6 REG is a direct upgrade for ABS4 REG in most cases: both share identical ABS package, pinout, and thermal characteristics, but ABS6 REG offers higher V_RRM (600 V vs. 400 V) with no penalty in size or cost. This provides improved surge margin in 230 V_AC systems. However, verify that layout clearance and insulation meet 600 V requirements, as ABS6 REG's higher rating does not relax creepage/clearance design rules.
