Product details
Overview
HDBL105GH from Taiwan Semiconductor is a 1A, 600V repetitive peak reverse voltage (VRRM) glass-passivated quad bridge rectifier in DBL package, featuring 1.7V max forward voltage at 1A and 75ns reverse recovery time, designed for high-efficiency AC/DC conversion in compact power adapters.
For engineers reviewing the HDBL105GH datasheet, HDBL105GH pinout, HDBL105GH application, or HDBL105GH equivalent, key selection criteria include its AEC-Q101 qualification, 50A peak surge current rating, UL recognition (E-326854), RoHS/halogen-free compliance, and thermal resistance of 15°C/W junction-to-lead.
Technical Context
This device integrates four silicon diodes in a single-phase full-wave bridge configuration with glass-passivated junctions for enhanced reliability under thermal cycling and humidity stress. Its DBL package uses matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
The HDBL105GH operates across -55°C to +150°C junction temperature range, supports 420V RMS reverse voltage, and delivers stable performance up to 1A average forward current with 10.3 A²s fusing I²t rating - critical for transient overload protection in SMPS front-end rectification.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6K (ON Semiconductor) | 600V VRRM, 6A IF, TO-220 package, 1.1V VF typical - higher current but larger footprint and no AEC-Q101 | Used in higher-power industrial PSUs where thermal mass compensates for lack of automotive qualification | Select when >1A average current or forced-air cooling is required; not drop-in due to package and pinout mismatch |
| MB10F (Vishay) | 600V VRRM, 1A IF, MBF package, 1.05V VF typical - smaller outline but only 30A IFSM and no AEC-Q101 or UL recognition | Common in cost-sensitive consumer adapters where qualification and surge margin are secondary | Choose for space-constrained designs accepting lower surge robustness and no automotive/safety certifications |
Compared with GBU6K and MB10F, the HDBL105GH uniquely combines AEC-Q101 qualification, UL recognition, and DBL package miniaturization - making it optimal for automotive-adjacent and safety-critical compact power supplies where reliability, certification, and size are jointly constrained.

FAQ
What is the peak repetitive reverse voltage rating for HDBL105GH?
The HDBL105GH has a repetitive peak reverse voltage (VRRM) rating of 600 V, verified per datasheet Table 1. This value defines the maximum instantaneous reverse voltage each diode in the bridge can block repeatedly without breakdown, and corresponds to a 420 V RMS input capability - sufficient for universal 90–264 VAC operation with safety margin. The "105" in HDBL105GH explicitly denotes the 600 V rating within the HDBL101G–HDBL107G series.
Is HDBL105GH qualified for automotive applications?
Yes, the "H" suffix in HDBL105GH indicates full AEC-Q101 qualification, confirmed in the Ordering Information section and Mechanical Data table. This includes stress testing for temperature cycling, high-temperature storage life, and biased HAST. The device is intended for automotive cabin electronics such as infotainment power supplies and body control module auxiliaries - not for safety-critical powertrain or ADAS main rails.
What does the DBL package designation mean for HDBL105GH?
The DBL package is Taiwan Semiconductor's proprietary molded plastic bridge rectifier outline with four gull-wing leads, defined in Package Outline Dimensions (Page 5). It measures 11.0 × 8.0 × 2.5 mm, features UL 94V-0 flammability rating, matte tin-plated leads compliant with J-STD-002, and a marked polarity indicator. Unlike TO-220 or GBPC packages, DBL enables surface-mount assembly with minimal PCB area and thermal resistance of 15°C/W junction-to-lead.
How does the forward voltage of HDBL105GH compare to lower-voltage variants in the same family?
HDBL105GH specifies a maximum forward voltage (VF) of 1.7 V at 1 A and 25°C - identical to HDBL106GH and HDBL107GH, and higher than HDBL101GH–HDBL104GH (1.0–1.3 V). This reflects the trade-off between higher blocking voltage and increased junction resistance. The 1.7 V VF directly increases conduction loss by ~0.7 W at full 1 A load versus 1.0 V devices, requiring appropriate thermal design in high-duty-cycle applications.
Does HDBL105GH have UL recognition and what is the file number?
Yes, HDBL105GH carries UL Recognition under file number E-326854, stated in the FEATURES section. This applies to the entire HDBL101G–HDBL107G family and confirms compliance with UL 60747-4 for discrete semiconductors. UL recognition permits use in end equipment seeking UL/CSA certification without requiring additional component-level investigation - reducing time-to-market for power supply approvals.
