Product details

Overview

D2SB10H from Taiwan Semiconductor is a 2A, 100V repetitive peak reverse voltage (V_RRM) AEC-Q101-qualified standard bridge rectifier in GBL package, featuring 80A surge capability, 1.1V max forward voltage at 2A, and 10µA max reverse current at 25°C - deployed in automotive-grade AC/DC front-end stages of onboard chargers and lighting drivers.

For engineers reviewing the D2SB10H datasheet, D2SB10H pinout, D2SB10H application, or D2SB10H equivalent, key selection criteria include V_RRM=100V, I_F=2A, AEC-Q101 qualification, GBL package thermal resistance (R_θJL=10°C/W), and UL recognition (E-326243) for safety-critical power conversion designs.

Technical Context

The D2SB10H integrates four silicon diodes in a single-phase full-wave bridge configuration with quad anode-cathode topology, enabling direct AC-to-DC rectification without external wiring. Its junction temperature range (–55°C to +150°C) and JESD201 Class 2 whisker resistance support under-hood automotive environments.

Thermal performance is defined by R_θJL = 10°C/W and R_θJA = 47°C/W, allowing sustained 2A conduction with minimal heatsinking in compact GBL-mounted PCB layouts. The device operates with 26A²s fusing rating for transient overcurrent protection during 8.3ms half-sine surges.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum non-repetitive reverse voltage the bridge withstands without breakdown; sets minimum input AC peak voltage rating.
I_F	2 A - Continuous average forward current per bridge; defines steady-state power handling in SMPS output stage.
I_FSM	80 A - Peak non-repetitive surge current for 8.3ms; supports inrush current tolerance in adapter input rectification.
V_F (max)	1.1 V - Max forward voltage drop per diode at 2A/25°C; determines conduction loss and thermal load in 2-diode conduction path.
R_θJL	10 °C/W - Junction-to-lead thermal resistance; enables direct thermal coupling to PCB copper for passive cooling in GBL footprint.
T_J max	+150 °C - Maximum allowable junction temperature; permits operation in high-ambient automotive engine bay locations.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
GBU2K (ON Semiconductor)	V_RRM=200V, I_F=2A, GBU package (larger than GBL), no AEC-Q101 qualification	Suitable for industrial/non-automotive SMPS where higher V_RRM margin is needed but automotive qualification is not required	Select when higher reverse voltage headroom is prioritized over automotive compliance and board space
DB107S (Diotec)	V_RRM=1000V, I_F=1A, SMD-4 package, RoHS-compliant but not AEC-Q101 or UL-recognized	Used in cost-sensitive consumer adapters where surge robustness and safety certification are secondary	Choose only for non-safety-critical, low-power applications with relaxed thermal and reliability requirements

Compared with GBU2K and DB107S, the D2SB10H uniquely combines AEC-Q101 qualification, UL recognition, and GBL's compact thermal profile - making it the only option among the three validated for automotive front-end rectification with zero safety certification overhead.

FAQ

What is the peak repetitive reverse voltage rating for D2SB10H?

The D2SB10H has a peak repetitive reverse voltage (V_RRM) rating of 100 V. This value is specified in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version K2103) and defines the maximum AC peak voltage the device can block in normal operation without avalanche breakdown. It is distinct from the 50V D2SB05 and 200V D2SB20 variants in the same family.

Is D2SB10H qualified to AEC-Q101, and what does the 'H' suffix indicate?

Yes, the 'H' suffix in D2SB10H explicitly denotes AEC-Q101 qualification per Taiwan Semiconductor's ordering information. This means the D2SB10H has undergone standardized stress testing for automotive applications-including temperature cycling, high-temperature reverse bias, and electrostatic discharge-making it suitable for use in passenger vehicle power electronics where reliability under harsh conditions is mandatory.

What is the forward voltage drop of D2SB10H at rated current?

The D2SB10H exhibits a maximum forward voltage drop (V_F) of 1.1 V per diode at I_F = 2 A and T_J = 25°C, as confirmed in the Electrical Specifications table. Since the bridge conducts through two diodes simultaneously in full-wave operation, the total conduction drop is approximately 2.2 V at full load - a critical parameter for calculating conduction losses and thermal design in the D2SB10H application.

Does D2SB10H have UL recognition, and what is the file number?

Yes, D2SB10H is UL Recognized under File # E-326243, as stated in the FEATURES section of the Taiwan Semiconductor datasheet. This recognition covers dielectric strength, flammability (UL 94V-0), and construction compliance - enabling direct use in end products targeting UL/CSA/EN 62368-1 certification without requiring additional component-level safety evaluation.

What package type does D2SB10H use, and what are its mechanical highlights?

D2SB10H uses the GBL package: a compact, surface-mount molded plastic case with matte tin-plated leads solderable per J-STD-002. Key mechanical attributes include UL 94V-0 flammability rating, JESD201 Class 2 whisker resistance, polarity marking on top surface, and a typical weight of 2.00 g - all verified in the MECHANICAL DATA section of the official datasheet.
