Diodes Incorporated PR2005-T

Overview

PR2005-T from Diodes Incorporated is a 2.0A, 600V peak repetitive reverse voltage fast recovery rectifier in DO-15 package, featuring 150ns reverse recovery time, 1.2V forward voltage at 2.0A, and 50A non-repetitive surge rating-used in offline AC/DC input stage rectification for industrial power supplies.

For engineers reviewing the PR2005-T datasheet, PR2005-T pinout, PR2005-T application, or PR2005-T equivalent, key selection criteria include VRRM derating at elevated ambient, trr impact on switching loss in PFC stages, IRM stability over temperature, and DO-15 thermal resistance (RθJA = 50°C/W) in constrained board layouts.

Technical Context

This axial-lead fast recovery rectifier employs a diffused PN junction to achieve low reverse recovery charge (Qrr implied by trr = 150ns at IF = 0.5A, IR = 1.0A), enabling reduced switching losses in 50/60Hz and quasi-resonant converter front-ends. Its 600V VRRM rating supports universal-input (85–265VAC) designs with margin against line transients.

Thermal performance is defined by RθJA = 50°C/W under standard JEDEC conditions (leads held at ambient 9.5mm from case), requiring PCB copper area optimization for sustained 2.0A IO at TA = 50°C. Reverse leakage remains ≤5.0μA at 25°C and ≤100μA at 100°C, critical for standby power compliance.

FAQ

Is PR2005-T suitable for use in new designs?

No-Diodes Incorporated explicitly marks PR2005-T as "NOT RECOMMENDED FOR NEW DESIGN" in its official datasheet (DS26010 Rev. 5). It remains available for legacy support and repair, but newer alternatives like the 150ns-rated FRED Pt series or shielded DO-214AD packages are advised for new projects requiring improved efficiency or reliability.

What is the maximum allowable ambient temperature for 2.0A continuous operation?

The rated average forward current IO = 2.0A is specified at TA = 50°C with leads held at ambient temperature at 9.5mm from the case per JEDEC standards. At TA = 70°C, the derated current drops to approximately 1.5A per Figure 1 in the datasheet; operation above 50°C requires thermal modeling or empirical validation.

How does the 150ns reverse recovery time affect EMI in a 60Hz rectifier application?

In 60Hz applications, trr = 150ns causes minimal EMI impact because di/dt during recovery is low relative to high-frequency switching converters. However, it prevents hard reverse recovery snap-off that could excite parasitic LC resonances in poorly damped input filters, contributing to lower conducted noise versus standard recovery rectifiers.

Can PR2005-T replace PR2004-T in an existing design?

Yes-PR2005-T (600V VRRM) is a direct voltage-upgrade replacement for PR2004-T (400V VRRM) with identical package, pinout, thermal characteristics, and forward parameters (VF, IO, trr). No layout or thermal changes are needed, and the higher blocking voltage improves surge immunity without trade-offs in conduction or switching behavior.
