Product details
Overview
DBLS153GH from Taiwan Semiconductor is a 1.5A, 200V repetitive peak reverse voltage (VRRM) AEC-Q101 qualified standard quad bridge rectifier in DBLS package, with 50A peak surge current (IFSM), 1.10V max forward voltage at 1.5A/25°C, and 2µA max reverse leakage at 25°C - used in automotive-grade AC-DC front-end conversion for lighting and adapters.
For engineers reviewing the DBLS153GH datasheet, DBLS153GH pinout, DBLS153GH application, or DBLS153GH equivalent, key selection criteria include VRRM rating, AEC-Q101 qualification status, thermal resistance (RθJL = 15°C/W), moisture sensitivity level (MSL 1), and UL recognition (E-326854).
Technical Context
This device integrates four diodes in a single-phase full-wave bridge configuration, enabling direct AC-to-DC conversion without external interconnection. It supports operation from –55°C to +150°C junction temperature and delivers stable performance under 8.3ms half-sine surge conditions (IFSM = 50A, I²t = 10.3 A²s).
The DBLS153GH uses matte tin-plated leads compliant with J-STD-002 solderability and passes JESD201 Class 2 whisker testing. Its molded plastic case meets UL 94V-0 flammability rating and RoHS/halogen-free requirements per IEC 61249-2-21.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU4K (ON Semiconductor) | VRRM = 400V, IF = 4.0A, larger GBU package (10.2 × 14.2 mm), no AEC-Q101 | Higher voltage/current rating; suited for higher-power SMPS but not automotive-qualified | Select when >200V VRRM or >1.5A IF required; verify PCB layout compatibility |
| DBLS153G (Taiwan Semiconductor) | Identical electrical specs except AEC-Q101 qualification; same DBLS package and marking code | Lacks automotive qualification; suitable for commercial/industrial use only | Choose DBLS153GH over DBLS153G only when AEC-Q101 compliance is mandatory |
Compared with GBU4K, DBLS153GH offers smaller footprint and automotive qualification but lower current rating; compared with DBLS153G, it adds AEC-Q101 validation without changing electrical or mechanical behavior - making it the sole choice for automotive lighting or control module designs requiring qualification evidence.

FAQ
What is the peak repetitive reverse voltage rating of DBLS153GH?
The DBLS153GH has a repetitive peak reverse voltage (VRRM) rating of 200 V, as specified in the Absolute Maximum Ratings table of the Taiwan Semiconductor DBLS151G–DBLS159G datasheet (Version M2103). This value defines the maximum AC voltage the device can block in each half-cycle without breakdown, and is confirmed by the marking code "153" (15x = 200V).
Is DBLS153GH qualified to AEC-Q101, and what does the "H" suffix indicate?
Yes, DBLS153GH is AEC-Q101 qualified - the "H" suffix in the ordering code explicitly denotes AEC-Q101 qualification per the Ordering Information section of the datasheet. This qualification covers stress tests including HTGB, HTRB, TCT, and UHAST, validating suitability for automotive under-hood and exterior lighting applications.
What is the forward voltage drop of DBLS153GH at rated current?
The DBLS153GH exhibits a maximum forward voltage (VF) of 1.10 V per diode at IF = 1.5 A and TJ = 25°C, as stated in the Electrical Specifications table. This value applies to DBLS151G through DBLS157G variants and reflects conduction loss under typical operating conditions.
Does DBLS153GH require moisture preconditioning before reflow soldering?
No, DBLS153GH does not require moisture preconditioning before reflow soldering because it is rated MSL Level 1 per J-STD-020. This means the device has unlimited floor life at ≤30°C/85% RH and may be placed directly into reflow without baking - a key advantage for high-throughput SMT lines.
What safety certifications does DBLS153GH hold?
DBLS153GH is UL Recognized under File # E-326854 and complies with RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21. These certifications support end-equipment safety approvals for industrial, commercial, and automotive power supplies.
