Diodes Incorporated D6G-T

Overview

D6G-T from Diodes Incorporated is a 1.0A glass passivated general-purpose rectifier diode with 800V peak repetitive reverse voltage (VRRM), 1.0V forward voltage at 1.0A (VFM), and 30A non-repetitive surge capability, used in AC/DC power supplies, DC-DC converter front-ends, and industrial power rectification.

For engineers reviewing the D6G-T datasheet, D6G-T pinout, D6G-T application, or D6G-T equivalent, key selection criteria include VRRM rating for input voltage margin, thermal resistance (RθJA = 100°C/W) for heatsink-free operation up to 75°C ambient, trr = 2.0µs for moderate-speed switching, and T-1 package compatibility with through-hole PCB layouts.

Technical Context

This device operates as a single-phase, half-wave silicon rectifier optimized for resistive or inductive loads at 60Hz line frequency. Its glass passivated junction ensures stable leakage performance across temperature, with IRM ≤ 50µA at 100°C under rated blocking voltage.

The T-1 molded plastic case (UL 94V-0) supports lead-free soldering per MIL-STD-202, Method 208, and its cathode band polarity marking enables unambiguous orientation during manual or automated assembly.

Key Specifications

Pinout & Package

Package: T-1 molded plastic case (25.4mm lead length, 2.6–3.2mm body width, 0.53–0.64mm lead diameter), UL 94V-0 rated, cathode band marked on body.

FAQ

Is D6G-T suitable for capacitive-input filter applications?

No-capacitive loads require 20% derating of IO per the datasheet. At full 1.0A rating, use only with resistive or inductive loads. For capacitive-input designs, limit continuous current to 0.8A to prevent overheating and premature failure due to peak current stress.

What is the maximum operating temperature for D6G-T in free-air conditions?

D6G-T supports operation from –65°C to +150°C junction temperature. In free-air (no heatsink), the 1.0A rating is valid only up to 75°C ambient, based on RθJA = 100°C/W and TJ(max) = 150°C. Above 75°C, linear derating applies per Figure 1.

Can D6G-T replace D5G-T in an existing design?

Yes-D6G-T is a direct upgrade from D5G-T (600V → 800V VRRM) with identical T-1 package, pinout, and thermal characteristics. No layout or thermal changes are needed; enhanced voltage margin improves reliability in high-line or transient-prone environments.

Does D6G-T meet automotive qualification standards?

No-D6G-T is not AEC-Q101 qualified. It is intended for industrial, commercial, and consumer applications. For automotive use, consider Diodes' AEC-Q101-certified rectifiers such as the SBxx series, which undergo extended temperature cycling and humidity testing.
