Product details
Overview
DBLS202GHC1G from Taiwan Semiconductor is a 2 A, 100 V repetitive peak reverse voltage (VRRM) standard quad bridge rectifier in DBLS surface-mount package, with 50 A peak surge current (IFSM), 1.15 V forward voltage at 2 A, and AEC-Q101 qualification - used in automotive-grade AC/DC front-end stages of LED drivers and compact adapters.
For engineers reviewing the DBLS202GHC1G datasheet, DBLS202GHC1G pinout, DBLS202GHC1G application, or DBLS202GHC1G equivalent, key selection criteria include VRRM = 100 V, IF = 2 A, thermal resistance RθJA = 40 °C/W, AEC-Q101 compliance, and DBLS package compatibility with high-density PCB layouts.
Technical Context
This device integrates four silicon diodes in a single-phase full-wave bridge configuration, enabling AC-to-DC conversion without external interconnects. Its DBLS molded plastic package supports reflow soldering per J-STD-002, with matte tin-plated leads and UL 94V-0 rated compound.
Designed for operation from −55 °C to +150 °C junction temperature, it delivers stable reverse leakage ≤2 µA at 25 °C and ≤500 µA at 125 °C, while sustaining 10.3 A²s fusing I²t rating under 8.3 ms half-sine surge conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU2K (ON Semiconductor) | Same 2 A / 100 V rating, but GBU through-hole package (10.5 mm × 14.2 mm); higher RθJA ≈ 50 °C/W | Suitable for prototyping or legacy through-hole designs; not SMT-compatible | Select when board-level rework or manual assembly is preferred over automated SMT placement |
| MB2S (Vishay) | 2 A / 100 V, SMB package (4.6 mm × 3.6 mm); lower IFSM = 30 A; no AEC-Q101 qualification | Used in cost-sensitive consumer power supplies where automotive qualification is unnecessary | Choose for space-constrained non-automotive applications where surge margin is less critical |
Compared with GBU2K and MB2S, DBLS202GHC1G uniquely combines AEC-Q101 qualification, DBLS SMT footprint, and 50 A surge rating - making it optimal for automotive-qualified, high-density, production-ready power supply designs requiring long-term supply stability.

FAQ
What is the peak repetitive reverse voltage rating for DBLS202GHC1G?
The DBLS202GHC1G has a repetitive peak reverse voltage (VRRM) rating of 100 V, as specified in the absolute maximum ratings table. This value defines the maximum reverse voltage the device can block repeatedly during normal operation without breakdown. It is confirmed across Taiwan Semiconductor's official DBLS201G–DBLS209G datasheet revision J2103 and applies specifically to the DBLS202GHC1G variant.
Is DBLS202GHC1G qualified for automotive applications?
Yes, DBLS202GHC1G is AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and explicitly stated in the FEATURES section. This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing - confirming suitability for automotive cabin and under-hood power electronics where reliability under thermal and mechanical stress is critical.
What does the "C1G" suffix mean in DBLS202GHC1G?
The "C1G" suffix in DBLS202GHC1G denotes tape-and-reel packaging (C1 = carrier tape specification) and green (halogen-free) molding compound (G). It follows Taiwan Semiconductor's standard ordering nomenclature where "H" indicates AEC-Q101 qualification and "C1G" specifies packaging and environmental compliance - distinct from the base DBLS202G part which lacks AEC-Q101 and may use standard compound.
What is the forward voltage drop of DBLS202GHC1G at rated current?
At IF = 2 A and TJ = 25 °C, the forward voltage drop (VF) of DBLS202GHC1G is 1.15 V maximum per diode, as listed in the ELECTRICAL SPECIFICATIONS table. This value reflects conduction loss across one diode leg in the bridge; total bridge drop is effectively two diode drops in series during conduction, i.e., ~2.3 V at full load.
Can DBLS202GHC1G be used in place of DBLS202G in new designs?
Yes, DBLS202GHC1G is a direct functional and pin-compatible upgrade to DBLS202G, adding AEC-Q101 qualification and halogen-free construction while retaining identical electrical parameters, DBLS package, and pinout. The "H" and "C1G" suffixes denote enhanced reliability and environmental compliance - making DBLS202GHC1G suitable for new automotive and industrial designs where those attributes are required.
