Product details
Overview
DBLS102GHRDG from Taiwan Semiconductor is a 1A, 100V repetitive peak reverse voltage (VRRM) standard quad bridge rectifier in DBLS surface-mount package, featuring 40A peak forward surge current (IFSM), 15 °C/W junction-to-lead thermal resistance, and AEC-Q101 qualification for automotive-grade reliability - used in compact AC/DC front-end stages of LED drivers and industrial adapters.
For engineers reviewing the DBLS102GHRDG datasheet, DBLS102GHRDG pinout, DBLS102GHRDG application, or DBLS102GHRDG equivalent, key selection criteria include VRRM = 100 V, IF = 1 A, IFSM = 40 A, RθJL = 15 °C/W, and AEC-Q101 qualification status - all verified per Taiwan Semiconductor P2103 datasheet.
Technical Context
This DBLS102GHRDG is a monolithic quad-diode bridge configured as a single-phase full-wave rectifier with integrated anode-cathode interconnects. It operates across –55 °C to +150 °C junction temperature range and supports soldering per J-STD-002 with matte tin-plated leads.
Thermal performance is defined by RθJL = 15 °C/W and RθJA = 40 °C/W under standard PCB mounting conditions. Electrical behavior includes VF ≤ 1.1 V at IF = 1 A, TJ = 25 °C, and IR ≤ 2 µA at rated VR, TJ = 25 °C.
Key Specifications

|---|---|
| VRRM | 100 V - maximum non-repetitive reverse voltage the bridge withstands without breakdown |
| IF | 1 A - continuous average forward current rating per device under specified thermal conditions |
| IFSM | 40 A - peak surge current capability for 8.3 ms half-sine wave, critical for inrush handling |
| RθJL | 15 °C/W - enables direct thermal path to PCB copper, supporting high-power density layouts |
| TJ max | +150 °C - allows operation in under-hood automotive or enclosed industrial environments |
| VF max | 1.1 V - forward voltage drop per diode at 1 A, directly impacts conduction loss and efficiency |
| IR max | 2 µA @ 25 °C - low leakage ensures minimal standby power loss in offline converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU4K | VRRM = 400 V, IF = 4 A, larger GBU package (10.5 × 14.5 mm), RθJA ≈ 50 °C/W | Suitable for higher-voltage, higher-current designs where board space and thermal budget allow larger footprint | Select when system requires >100 V VRRM or >1 A IF; not drop-in due to different pinout and size |
| MB10F | VRRM = 100 V, IF = 1 A, MBF package (8.5 × 6.5 mm), IFSM = 30 A, no AEC-Q101 qualification | General-purpose consumer-grade alternative lacking automotive qualification and surge margin | Acceptable for cost-sensitive non-automotive applications where 30 A IFSM suffices and AEC-Q101 is not required |
Compared with GBU4K and MB10F, DBLS102GHRDG uniquely combines AEC-Q101 qualification, 40 A surge rating, and compact DBLS footprint - making it optimal for space-constrained automotive and industrial rectification where reliability and thermal performance are prioritized over raw current headroom.

FAQ
What is the peak repetitive reverse voltage rating of DBLS102GHRDG?
The DBLS102GHRDG has a repetitive peak reverse voltage (VRRM) rating of 100 V, as specified in the Taiwan Semiconductor P2103 datasheet. This value is fixed for the "102" variant and confirmed across absolute maximum ratings tables. Exceeding this voltage risks irreversible avalanche breakdown. The DBLS102GHRDG must be applied within this limit under all operating conditions, including transients and temperature extremes.
Is DBLS102GHRDG qualified for automotive applications?
Yes, DBLS102GHRDG is AEC-Q101 qualified, as indicated by the "H" suffix in the ordering code and explicitly stated in the features section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including temperature cycling, humidity bias, and high-temperature operating life - confirming suitability for automotive body electronics, lighting, and infotainment power supplies.
What does the "HRDG" suffix mean in DBLS102GHRDG?
The "HRDG" suffix in DBLS102GHRDG denotes tape-and-reel packaging (H), RoHS compliance (R), green compound (G), and date code/traceability marking (D). It aligns with Taiwan Semiconductor's ordering nomenclature where "H" indicates AEC-Q101 qualification and "R" confirms RoHS conformance - both verified in the official P2103 document revision.
What is the thermal resistance from junction to ambient for DBLS102GHRDG?
The junction-to-ambient thermal resistance (RθJA) of DBLS102GHRDG is 40 °C/W under standard JEDEC test conditions (1-inch² copper pad, 1 oz Cu). This value is specified in the Thermal Performance table of the P2103 datasheet and assumes no additional heatsinking. Actual board-level RθJA will vary based on PCB copper area and airflow.
Can DBLS102GHRDG replace DBLS102G in existing designs?
Yes, DBLS102GHRDG is a functionally identical and pin-compatible variant of DBLS102G, with added RoHS compliance (R), green compound (G), and traceable date coding (D). Electrical, thermal, and mechanical specifications match exactly per the P2103 datasheet. No layout or schematic changes are required when upgrading from DBLS102G to DBLS102GHRDG.
