DBLS102GHC1G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DBLS102GHC1G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, designed for 100 V peak reverse voltage applications with 1 A average rectified current capacity. This component is classified as an active product with AEC-Q101 automotive qualification and ROHS3 compliance. Bridge rectifiers of this specification are essential in power supply circuits requiring AC-to-DC conversion with integrated four-diode bridge configurations in surface mount packages. Substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the same package category.

Frequently Asked Questions (FAQ)

Q: Can DF01S-E3/45 or DF01SA-E3/45 be used as direct replacements for DBLS102GHC1G?

A: Yes. Both Vishay parts match the critical electrical parameters (100 V peak reverse voltage, 1 A average rectified current, 1.1 V forward voltage at 1 A) and mechanical specifications (4-SMD Gull Wing surface mount package). Operating temperature range, RoHS compliance, and MSL rating are identical across all three parts.

Q: What is the difference between DF01S-E3/45 and DF01SA-E3/45?

A: Both parts are electrically and mechanically identical. They share the same electrical specifications, package configuration, and compliance certifications. The difference lies in the manufacturer's internal designation and packaging format (both supplied in tubes).

Q: Are there any differences in reverse leakage current between the main part and substitutes?

A: The DBLS102GHC1G specifies 2 µA reverse leakage at 100 V, while both Vishay substitutes specify 5 µA at 100 V. This difference remains within acceptable operating parameters for standard bridge rectifier applications at the specified voltage and temperature range.

Q: Is the DBLS102GHC1G automotive-qualified?

A: Yes. The DBLS102GHC1G carries AEC-Q101 automotive qualification. The Vishay substitutes (DF01S-E3/45 and DF01SA-E3/45) do not list AEC-Q101 qualification in the provided specifications. For automotive applications requiring AEC-Q101 certification, the DBLS102GHC1G is the specified choice.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All three parts use identical 4-SMD Gull Wing surface mount package configuration, enabling direct PCB footprint compatibility without layout modifications.

Q: What is the moisture sensitivity level for these parts?

A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
