Taiwan Semiconductor Corporation D2SB60

Overview

D2SB60 from Taiwan Semiconductor is a 2A, 600V repetitive peak reverse voltage (V_RRM) standard bridge rectifier in GBL package, configured as a quad diode arrangement for full-wave AC-to-DC conversion. It delivers 80A surge current capability (I_FSM), operates up to 150°C junction temperature, and is widely used in offline switch-mode power supplies requiring compact, high-reliability rectification.

For engineers reviewing the D2SB60 datasheet, D2SB60 pinout, D2SB60 application, or D2SB60 equivalent, key selection factors include its 600V V_RRM, 2A average forward current rating, 1.1V max forward voltage at 2A/25°C, UL recognition (E-326243), and AEC-Q101 qualification option (D2SB60H) for automotive-grade designs.

Technical Context

The D2SB60 integrates four silicon PN-junction diodes in a single-phase bridge configuration, enabling full-wave rectification without external interconnection. Its GBL package provides 10°C/W junction-to-lead thermal resistance and meets UL 94V-0 flammability requirements with matte tin-plated leads compliant to J-STD-002 solderability.

Electrical behavior is defined by 10µA max reverse leakage at 25°C and 500µA at 125°C under rated reverse voltage, with 26A²s fusing I²t rating for transient surge protection. Polarity is marked on the case per industry-standard bridge orientation.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) of the D2SB60?

The D2SB60 has a maximum repetitive peak reverse voltage (V_RRM) of 600 V. This rating ensures reliable blocking of reverse voltage during the negative half-cycle of AC input, supporting universal mains operation (85–265V AC) with adequate safety margin. The D2SB60 datasheet confirms this value under absolute maximum ratings at TA = 25°C.

Does the D2SB60 have automotive qualification?

The base D2SB60 is not AEC-Q101 qualified, but the variant D2SB60H is explicitly qualified to AEC-Q101. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life-making D2SB60H suitable for automotive infotainment and body electronics. Always specify the "H" suffix when automotive-grade reliability is required.

What is the forward voltage drop (V_F) specification for the D2SB60?

The D2SB60 has a maximum forward voltage drop of 1.1 V per diode at 2 A forward current and 25°C junction temperature. This value is measured under pulsed conditions (PW = 0.3 ms) and directly affects conduction losses and thermal design. At elevated temperatures (e.g., 125°C), V_F decreases slightly, improving efficiency under thermal stress.

What package type does the D2SB60 use, and what are its key mechanical properties?

The D2SB60 uses the GBL package-a molded plastic body with 4 external leads, UL 94V-0 flammability rating, and matte tin-plated terminals compliant with J-STD-002 solderability. It weighs approximately 2.00 g and features marked polarity. The GBL outline provides optimized creepage/clearance for 600V isolation and supports manual or automated PCB assembly.

How does the D2SB60 compare to the D2SB40 in terms of voltage rating and application scope?

The D2SB60 is rated for 600 V V_RRM, while the D2SB40 is rated for 400 V. This 200 V difference defines their application boundaries: D2SB60 supports higher-line applications (e.g., 230V AC regions with surge margins), whereas D2SB40 suits 115V AC or lower-voltage industrial systems. Both share identical I_F (2 A), I_FSM (80 A), and GBL packaging, enabling footprint-compatible upgrades.
