Diodes Incorporated PR3005G-T

Overview

PR3005G-T from Diodes Incorporated is a 600 V, 3.0 A fast recovery glass passivated rectifier diode in DO-201AD package, designed for AC/DC input stage rectification in offline power supplies and DC-DC front-end stages. It delivers 150 ns reverse recovery time, 1.3 V forward voltage at 3.0 A, and withstands 125 A non-repetitive surge current - enabling high-efficiency operation in compact industrial and consumer SMPS designs.

For engineers reviewing the PR3005G-T datasheet, PR3005G-T pinout, PR3005G-T application, or PR3005G-T equivalent, key selection criteria include peak repetitive reverse voltage (600 V), average forward current rating (3.0 A @ 55°C), fast recovery performance (150 ns), low leakage (<5.0 µA @ 25°C), and DO-201AD mechanical compatibility with standard through-hole layouts.

Technical Context

This device operates as a single-phase, half-wave rectifier under resistive or inductive loads at 60 Hz, with derating required for capacitive loads (−20% current). Its glass passivated die construction ensures stable junction integrity and enhanced moisture resistance versus epoxy-passivated alternatives.

The 150 ns reverse recovery time (measured at IF = 0.5 A, IR = 1 A, Irr = 0.25 A) supports switching frequencies up to ~100 kHz in flyback and forward converters, while its 32 °C/W junction-to-ambient thermal resistance enables reliable operation without forced airflow in ambient temperatures up to +150°C.

Manufacturer

Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, specializing in high-reliability power management, signal integrity, and protection solutions for industrial, computing, and consumer markets.

The PR300xG series targets cost-sensitive, high-volume rectification applications where fast recovery, surge robustness, and RoHS compliance are mandatory - particularly in offline power conversion where DO-201AD form factor remains dominant.

FAQ

What is the maximum allowable ambient temperature for continuous 3.0 A operation?

PR3005G-T supports 3.0 A average forward current only when leads are maintained at ambient temperature at a distance of 9.5 mm from the case, and ambient temperature does not exceed +55°C. Above this, current must be linearly derated per Figure 1 - e.g., 2.0 A at +100°C ambient.

Is PR3005G-T suitable for use in capacitive-input filter configurations?

No - the datasheet explicitly requires 20% current derating for capacitive loads due to higher peak currents and increased thermal stress. For such applications, consider using a higher-current-rated device like PR3006G-T (800 V) or verify thermal performance with worst-case ripple and ESR modeling.

Does PR3005G-T have a specified reverse recovery charge (Qrr)?

No Qrr value is provided in the DS27003 datasheet. Only trr = 150 ns is specified under defined test conditions (IF = 0.5 A, IR = 1 A, Irr = 0.25 A). Designers requiring Qrr for loss calculation should consult Diodes Incorporated's application notes or request characterization data directly.

Why is PR3005G-T marked "NOT RECOMMENDED FOR NEW DESIGN"?

This designation reflects Diodes Incorporated's internal product lifecycle policy - likely due to newer alternatives (e.g., faster, lower-VF, or smaller-package rectifiers) being prioritized for new designs. However, PR3005G-T remains fully qualified, in active production, and supported for existing designs and legacy replacements.
