Diodes Incorporated GBL410_HF

Overview

GBL410_HF from Diodes Incorporated is a 4A, 1000V glass passivated single-phase bridge rectifier in GBL package, featuring 150A non-repetitive surge capability, 1.0V forward voltage at 2.0A per element, and 5µA reverse leakage at 25°C - deployed in AC/DC power supplies for industrial motor drives and LED lighting ballasts.

For engineers reviewing the GBL410_HF datasheet, GBL410_HF pinout, GBL410_HF application, or GBL410_HF equivalent, key selection criteria include peak repetitive reverse voltage (1000V), average forward current with heatsink (4.0A), thermal resistance junction-to-case (4.2°C/W), and RoHS-compliant green packaging.

Technical Context

This bridge rectifier integrates four silicon diodes in a single-phase full-wave configuration with glass passivated die construction to ensure stable reverse blocking under transient overvoltage conditions. Its 700V RMS reverse rating and 1000V VRRM support universal input (85–265VAC) front-end rectification.

Thermal performance is defined by junction-to-lead resistance of 4.0°C/W and junction-to-ambient of 10°C/W on standard PCB mounting; derating applies for capacitive loads (−20% current rating). Polarity is marked on the body with date code and type number.

Key Specifications

Pinout & Package

GBL410_HF uses the GBL molded plastic package (UL 94V-0), measuring 20.5mm × 11.0mm × 3.5mm (L×E×h), with matte tin terminals solderable per MIL-STD-202 Method 208. Polarity marking on body identifies AC input (±) and DC output (+/−) terminals.

FAQ

What is the maximum allowable junction temperature for GBL410_HF?

The absolute maximum junction temperature is +150°C, as specified in the datasheet's Operating and Storage Temperature Range. This limit must be maintained under worst-case ambient, power dissipation, and heatsinking conditions - verified using RθJC = 4.2°C/W and measured forward voltage drop at operating current.

Can GBL410_HF be used without a heatsink?

Yes, but only at reduced current: the datasheet specifies 2.4A average forward current without heatsink. Operation above this requires thermal management - such as a 50×50×1.6mm copper plate - to prevent junction temperature exceedance under continuous load.

Is GBL410_HF compatible with lead-free reflow soldering processes?

Yes - it features matte tin terminals qualified per MIL-STD-202 Method 208 and complies with J-STD-020 Level 1 moisture sensitivity. Peak reflow temperature up to 260°C is supported, consistent with standard Pb-free assembly profiles.

How does the GBL410_HF differ from the GBL405_HF?

GBL410_HF has higher peak repetitive reverse voltage (1000V vs. 600V) and higher surge current rating (150A vs. 120A), while sharing identical GBL package, pinout, and thermal characteristics. It replaces GBL405_HF in designs requiring enhanced transient immunity or wider input voltage range.
