FAQ

What is the peak repetitive reverse voltage rating of the DBLS107GH?

The DBLS107GH has a repetitive peak reverse voltage (VRRM) rating of 1000 V. This value is confirmed in the Absolute Maximum Ratings table on page 2 of the official Taiwan Semiconductor datasheet (Version P2103). It defines the maximum instantaneous reverse voltage the device can block repeatedly without breakdown, supporting AC inputs up to approximately 707 Vrms in full-wave configurations. The DBLS107GH maintains this rating across its full operating temperature range.

Is the DBLS107GH qualified for automotive applications?

Yes, the DBLS107GH is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and stated in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing. The DBLS107GH is intended for use in automotive power supplies such as LED headlamps, body control modules, and infotainment system AC/DC stages.

What does the "H" suffix in DBLS107GH signify?

The "H" suffix in DBLS107GH denotes AEC-Q101 qualification, per the Ordering Information table on page 3 of the Taiwan Semiconductor datasheet (Version P2103). It distinguishes this variant from the standard DBLS107G, which lacks automotive qualification. Both share identical electrical ratings and DBLS package, but only DBLS107GH is tested and certified to AEC-Q101 requirements for stress reliability in automotive environments.

What is the thermal resistance from junction to lead (RθJL) for the DBLS107GH?

The DBLS107GH has a typical junction-to-lead thermal resistance (RθJL) of 15 °C/W, as specified in the THERMAL PERFORMANCE table on page 2 of the Taiwan Semiconductor datasheet. This low value reflects efficient heat conduction from the silicon die through the internal leadframe to the PCB pads, enabling reliable operation at 1 A continuous current without additional heatsinking in properly designed layouts.

Does the DBLS107GH meet RoHS and halogen-free requirements?

Yes, the DBLS107GH is RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as confirmed in the FEATURES section of the Taiwan Semiconductor datasheet. These compliance statements apply specifically to the DBLS107GH variant and are verified through material declarations and third-party testing. The halogen-free status supports environmental regulations in EU, China, and other major markets, and contributes to safer combustion behavior in end equipment.
