Taiwan Semiconductor Corporation HDBL101GH

Overview

HDBL101GH from Taiwan Semiconductor is a 1A, 50V glass-passivated quad bridge rectifier in DBL package, featuring 50A peak surge current, 150°C max junction temperature, and AEC-Q101 qualification-designed for high-reliability AC/DC conversion in automotive-grade power adapters.

For engineers reviewing the HDBL101GH datasheet, HDBL101GH pinout, HDBL101GH application, or HDBL101GH equivalent, key selection criteria include repetitive peak reverse voltage (50 V), forward voltage (1.0 V @ 1 A), thermal resistance (15 °C/W junction-to-lead), and AEC-Q101 qualification status for under-hood deployment.

Technical Context

This device integrates four silicon diodes in a single-phase full-wave bridge configuration with glass-passivated junctions for enhanced moisture and contamination resistance. Its DBL molded plastic package supports surface-mount assembly and meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance standards.

The HDBL101GH operates across –55°C to +150°C junction temperature range, delivers 10.3 A²s fusing I²t rating, and exhibits 50 ns reverse recovery time at IF = 0.5 A / IR = 1.0 A-enabling efficient operation in high-frequency switching mode power supplies up to several hundred kHz.

FAQ

What is the peak repetitive reverse voltage rating for HDBL101GH?

The HDBL101GH has a repetitive peak reverse voltage (VRRM) rating of 50 V per diode leg. This value defines the maximum instantaneous reverse voltage the device can block repeatedly without breakdown. It is specified under standard test conditions (TA = 25°C) and forms the basis for selecting appropriate input filtering and snubber components in 50 V-rated AC/DC designs. The HDBL101GH must not be operated beyond this rating in continuous service.

Is HDBL101GH qualified for automotive applications?

Yes, the HDBL101GH is explicitly AEC-Q101 qualified, as confirmed in the official Taiwan Semiconductor datasheet (Version G2103). This qualification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST). The "H" suffix in HDBL101GH denotes AEC-Q101 compliance, making it suitable for automotive power conversion modules where reliability under thermal and mechanical stress is mandatory.

What is the forward voltage drop of HDBL101GH at rated current?

The HDBL101GH exhibits a typical forward voltage (VF) of 1.0 V at IF = 1 A and TJ = 25°C, as measured under pulsed conditions (PW = 0.3 ms). This value directly impacts conduction loss and thermal design-e.g., at full load, conduction loss is approximately 1.0 W per bridge, requiring adequate PCB copper area or thermal relief. VF increases with junction temperature, reaching ~1.2 V at TJ = 125°C.

Does HDBL101GH have a defined reverse recovery time?

Yes, the HDBL101GH has a specified reverse recovery time (trr) of 50 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This fast recovery characteristic reduces switching losses and EMI generation in high-frequency SMPS designs. The trr value applies to all variants from HDBL101G through HDBL104G; higher-voltage variants (HDBL105G–HDBL107G) specify 75 ns.

What package type does HDBL101GH use and what are its mounting features?

HDBL101GH uses the DBL surface-mount package-a compact, molded plastic housing with four gull-wing leads. It features matte tin-plated terminals compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. The DBL package meets UL 94V-0 flammability rating and is optimized for automated reflow assembly. Polarity is clearly marked on the top surface, and the device weighs approximately 0.360 g.
