FAQ

What is the peak repetitive reverse voltage rating for HDBL103GH?

The HDBL103GH has a repetitive peak reverse voltage (VRRM) rating of 200 V, verified per Taiwan Semiconductor's G2103 datasheet. This value defines the maximum instantaneous reverse voltage each diode can block repeatedly without breakdown. It corresponds to an RMS input voltage limit of approximately 141 VAC, making HDBL103GH suitable for 120 VAC and 230 VAC-derived low-voltage transformer outputs in regulated power supplies.

Is HDBL103GH qualified for automotive applications?

Yes, HDBL103GH is AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code. This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT). The HDBL103GH is intended for use in automotive subsystems such as LED lighting drivers and infotainment power supplies where extended temperature operation and long-term reliability are mandatory.

What is the forward voltage drop of HDBL103GH at rated current?

The forward voltage drop (VF) of HDBL103GH is guaranteed ≤1.0 V at IF = 1 A and TJ = 25 °C, per the electrical specifications table in the official datasheet. This low VF contributes to reduced conduction losses and improved thermal efficiency in high-density power supplies. At elevated junction temperatures (e.g., 125 °C), VF decreases slightly due to silicon's negative temperature coefficient.

Does HDBL103GH have a specified reverse recovery time?

Yes, HDBL103GH has a maximum reverse recovery time (trr) of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast recovery characteristic minimizes switching losses and associated EMI in high-frequency rectification circuits, especially when paired with modern PFC or resonant converters. Slower alternatives like MB10F (150 ns) are unsuitable where trr-driven loss or noise is critical.

What package type does HDBL103GH use and what are its mounting features?

HDBL103GH uses the DBL surface-mount package - a compact, molded plastic case with matte tin-plated leads compliant with J-STD-002 solderability requirements. It features polarity marking on the top surface, weighs approximately 0.360 g, and meets UL 94V-0 flammability rating. The DBL package enables automated placement and reflow soldering while offering superior thermal performance (RθJL = 15 °C/W) compared to standard SMD bridge packages.
