Diodes Incorporated PR3002G-T

Overview

PR3002G-T from Diodes Incorporated is a 3.0A fast recovery glass passivated rectifier diode in DO-201AD package, rated for 100V peak repetitive reverse voltage (VRRM), 1.3V forward voltage at 3.0A, and 125A non-repetitive surge current, used in AC/DC input stage rectification for industrial power supplies.

For engineers reviewing the PR3002G-T datasheet, PR3002G-T pinout, PR3002G-T application, or PR3002G-T equivalent, key selection criteria include VRRM rating, trr of 150 ns, thermal resistance of 32°C/W, and DO-201AD mechanical compatibility with high-current PCB layouts.

Technical Context

This device operates as a single-phase, half-wave rectifier under resistive or inductive loads at 60Hz, with derating required for capacitive loads. Its glass passivated die construction ensures stable reverse leakage (<5.0 μA at 25°C) and robust surge tolerance up to 125A (8.3ms half-sine).

The 150 ns reverse recovery time (trr) supports switching frequencies up to ~1 MHz in flyback and boost PFC stages. Thermal performance is defined by RθJA = 32°C/W, assuming leads maintained at ambient temperature at 9.5 mm from case per JEDEC standard.

FAQ

Is PR3002G-T RoHS compliant?

Yes, PR3002G-T features lead-free finish and complies with RoHS Directive 2011/65/EU (Revision 13.2.2003), including exemptions for glass and high-temperature solder per EU Annex Notes 5 and 7. Tin-plated leads meet MIL-STD-202 Method 208 solderability requirements.

What is the maximum operating temperature for PR3002G-T?

The junction and storage temperature range is –65°C to +150°C. At 55°C ambient, it delivers full 3.0A average forward current; derating begins above that per Figure 1, reaching ~1.5A at 100°C ambient due to RθJA = 32°C/W and thermal saturation.

Can PR3002G-T replace PR3001G in existing designs?

Yes, PR3002G-T is a direct functional replacement for PR3001G with identical DO-201AD package and pinout, differing only in VRRM (100V vs. 50V) and VR(RMS) (70V vs. 35V). No layout change is needed, but verify reverse voltage margin in circuit operation.

Does PR3002G-T require a heatsink in typical applications?

No heatsink is required when operated at ≤3.0A average current with leads maintained at ambient temperature at 9.5mm from case, per datasheet condition. For sustained >2.0A in enclosed environments, ≥1.5 cm² copper pour is recommended to manage 32°C/W thermal resistance.
