Taiwan Semiconductor Corporation HDBL104GH

Overview

HDBL104GH from Taiwan Semiconductor is a 1A, 400V repetitive peak reverse voltage (VRRM) glass-passivated quad bridge rectifier in DBL package, featuring 50A peak forward surge current (IFSM), 15°C/W junction-to-lead thermal resistance, and AEC-Q101 qualification for automotive-grade reliability. It serves as the AC-to-DC input stage in compact switching mode power supplies.

For engineers reviewing the HDBL104GH datasheet, HDBL104GH pinout, HDBL104GH application, or HDBL104GH equivalent, key selection criteria include its 400V VRRM rating, 1.3V max forward voltage at 1A/25°C, 50ns reverse recovery time, AEC-Q101 qualification status, and DBL surface-mount package compatibility with high-density PCB layouts.

Technical Context

The HDBL104GH integrates four silicon diodes in a single-phase full-wave bridge configuration with glass-passivated junctions for enhanced moisture and contamination resistance. Its DBL package uses matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker testing.

Thermally, it delivers R_θJL = 15°C/W and R_θJA = 40°C/W, enabling operation up to 150°C junction temperature. Electrical behavior is defined by 5µA max reverse leakage at 25°C and 500µA at 125°C under rated reverse voltage.

FAQ

What is the maximum junction temperature rating for the HDBL104GH?

The HDBL104GH has a maximum junction temperature (T_J) of +150°C, verified per AEC-Q101 stress testing. This allows continuous operation in high-ambient environments such as automotive under-dash enclosures or enclosed LED drivers. Derating curves in the datasheet define safe IF limits above 25°C ambient, and the 15°C/W R_θJL supports effective thermal transfer to PCB copper.

Is the HDBL104GH pin-compatible with other parts in the HDBL10xG series?

Yes, all HDBL10xG and HDBL10xGH variants-including HDBL104GH-share identical DBL package dimensions, terminal layout, and pinout (AC1, AC2, +, −). Only VRRM (400V), VF (1.3V max), and trr (50ns) differ across the series; mechanical and soldering compatibility is fully maintained for design reuse and BOM flexibility.

Does the HDBL104GH meet RoHS and halogen-free requirements?

Yes, the HDBL104GH is RoHS compliant and halogen-free per IEC 61249-2-21. The "G" suffix denotes green compound, and the "H" suffix confirms AEC-Q101 qualification-both verified in TSC's G2103 revision documentation. Material declarations and test reports are available upon request for compliance audits.

What is the reverse leakage current specification for the HDBL104GH at elevated temperature?

The HDBL104GH specifies a maximum reverse current (I_R) of 500 µA per diode at 125°C and rated V_RRM, measured with 30ms pulse width. At 25°C, leakage is limited to 5 µA. This low, thermally stable leakage ensures minimal standby power loss in always-on lighting and adapter applications.

How does the AEC-Q101 qualification of the HDBL104GH impact its use in non-automotive applications?

AEC-Q101 qualification certifies the HDBL104GH for extreme temperature cycling, high-temperature reverse bias, and mechanical shock-making it exceptionally robust for industrial, medical, and high-reliability consumer applications even outside automotive. Designers benefit from extended lifetime prediction, reduced field failure risk, and simplified qualification effort when using HDBL104GH in demanding environments.
