Product details

Overview

DBLS107G-T from Taiwan Semiconductor is a 1 A, 1000 V repetitive peak reverse voltage (V_RRM) standard quad bridge rectifier in DBLS package, with 40 A peak forward surge current (I_FSM), 15 °C/W junction-to-lead thermal resistance, and RoHS/halogen-free compliance - used in high-reliability AC/DC front-end stages of offline SMPS.

For engineers reviewing the DBLS107G-T datasheet, DBLS107G-T pinout, DBLS107G-T application, or DBLS107G-T equivalent, key selection factors include verified 1000 V V_RRM, 40 A I_FSM, 1.1 V max forward voltage at 1 A, J-STD-020 Level 1 moisture sensitivity, and UL Recognized File # E-326854 compliance for safety-critical power conversion designs.

Technical Context

This device implements a monolithic quad-diode bridge configuration with common-cathode/common-anode topology in a single DBLS molded plastic package. It delivers full-wave rectification without external interconnection, supporting continuous 1 A average forward current at up to +150 °C junction temperature.

Thermal performance is defined by R_θJL = 15 °C/W and R_θJA = 40 °C/W, enabling direct PCB heat sinking via leads. Its 1000 V V_RRM rating targets universal-input (85–265 V_AC) and high-line industrial applications where transient overvoltage margin is critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - Withstands repetitive reverse voltage up to 1000 V, suitable for 277 V_AC and 400 V_DC bus applications with safety margin.

I_FSM	40 A (8.3 ms half-sine) - Handles high-energy line surges without failure, critical for input-stage robustness in unregulated AC inputs.
V_F	≤1.1 V @ 1 A, 25 °C - Limits conduction loss and self-heating during steady-state operation in compact power supplies.
R_θJL	15 °C/W - Enables efficient heat transfer from die to PCB copper through leads, supporting higher ambient operation without heatsink.
T_J max	+150 °C - Allows operation in thermally constrained enclosures such as LED drivers and enclosed adapters.
Moisture Sensitivity	Level 1 (J-STD-020) - No bake requirement prior to reflow; compatible with standard SMT assembly processes.

Equivalent & Alternatives

The following parts are listed as comparable options for similar bridge rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
GBU6K-E3/51 (Vishay)	6 A rating, 800 V V_RRM, GBU package (larger footprint, higher I_F)	Better suited for higher-current (>1.5 A) designs; not drop-in due to different pinout and size.	Select when higher average current capability is required and board space allows larger GBU outline.
GBU4J (ON Semiconductor)	4 A rating, 600 V V_RRM, same DBLS pin compatibility but lower voltage rating	Acceptable only for ≤230 V_AC systems; insufficient margin for 277 V_AC or surge-prone environments.	Use only in cost-sensitive, low-voltage AC applications where 1000 V margin is unnecessary.

Compared with GBU6K-E3/51 and GBU4J, DBLS107G-T uniquely balances 1000 V standoff, 1 A continuous rating, and compact DBLS footprint - making it optimal for space-constrained, high-line industrial and commercial power supplies where voltage margin and thermal efficiency are prioritized over raw current headroom.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for DBLS107G-T?

The DBLS107G-T has a V_RRM of 1000 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version C2103). This rating applies specifically to DBLS107G-T and distinguishes it from lower-voltage variants like DBLS104G-T (400 V) and DBLS106G-Y (800 V). The 1000 V rating enables use in 277 V_AC and high-line industrial systems.

Does DBLS107G-T have UL recognition?

Yes, DBLS107G-T is UL Recognized under File # E-326854, as stated in the FEATURES section of the Taiwan Semiconductor datasheet. This certification covers the entire DBLS104G-T to DBLS107G-T family and validates compliance with UL/CSA safety standards for use in end equipment requiring regulatory approval in North America.

What is the peak forward surge current (I_FSM) rating for DBLS107G-T?

The DBLS107G-T has an I_FSM rating of 40 A for an 8.3 ms single half-sine wave, per the Absolute Maximum Ratings table. This value is higher than DBLS105G-T (30 A) and DBLS106G-Y (30 A), reflecting optimized surge capability for the 1000 V variant. It supports robustness against line surges and cold-start inrush in offline power supplies.

Is DBLS107G-T RoHS and halogen-free compliant?

Yes, DBLS107G-T is both RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as explicitly noted in the FEATURES section of the Taiwan Semiconductor datasheet. The "G" suffix in the part number denotes green (halogen-free) molding compound, and all DBLS104G-T through DBLS107G-T variants share this environmental compliance.

What is the thermal resistance from junction to lead (R_θJL) for DBLS107G-T?

The junction-to-lead thermal resistance (R_θJL) for DBLS107G-T is 15 °C/W, as specified in the THERMAL PERFORMANCE section of the datasheet. This value is identical across the DBLS104G-T to DBLS107G-T family and enables effective heat transfer from the silicon die to the PCB through the leads, supporting reliable operation at up to +150 °C junction temperature.
