Diodes Incorporated PR3001-T

Overview

PR3001-T from Diodes Incorporated is a 3.0A fast recovery rectifier diode in DO-201AD package, rated for 50V peak repetitive reverse voltage (VRRM), 1.2V forward voltage at 3.0A (VFM), and 150ns reverse recovery time (trr). It delivers low leakage (5.0mA @ 25°C), high surge capability (150A peak), and RoHS-compliant tin-plated leads - used in AC/DC front-end rectification for industrial power supplies and LED drivers.

For engineers reviewing the PR3001-T datasheet, PR3001-T pinout, PR3001-T application, or PR3001-T equivalent, key selection criteria include VRRM margin vs. line transients, thermal derating above 90°C ambient, trr impact on switching loss in 50–60Hz half-wave topologies, and DO-201AD board layout clearance per IPC-7351B.

Technical Context

This device employs a diffused PN junction optimized for fast recovery (trr = 150ns) with controlled minority carrier lifetime, enabling efficient operation in single-phase, half-wave rectification under resistive or inductive loads at 60Hz. Its 15°C/W junction-to-ambient thermal resistance supports 3.0A average current only when leads are held at ambient temperature at ≥9.5mm from case.

Reverse recovery is characterized using IF = 0.5A, IR = 1.0A, and Irr = 0.25A per Figure 5; total capacitance is 50pF at 1.0MHz and 4.0V reverse bias. The cathode band polarity marking and DO-201AD mechanical outline (A: 25.4mm, B: 7.2–9.5mm, C: 1.2–1.3mm, D: 4.8–5.3mm) are fully defined per JEDEC TO-201AD standard.

FAQ

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

PR3001-T sustains 3.0A average forward current only when leads are maintained at ≤90°C ambient temperature at a distance of 9.5mm from the case. Above 90°C, derating follows Figure 1: at 125°C ambient, IO drops to ~1.8A. Forced airflow or PCB copper thermal relief is required for sustained full-load operation in enclosed environments.

Can PR3001-T be used in full-wave bridge configurations?

No - PR3001-T is a single anode-cathode diode intended for half-wave rectification. For full-wave bridges, four PR3001-T units may be assembled externally, but Diodes Incorporated does not specify or characterize this configuration. Dedicated bridge rectifiers (e.g., DB101–DB107 series) are recommended for full-wave applications due to matched parameters and validated thermal coupling.

Is PR3001-T suitable for capacitive-input filter loads?

Yes, but with 20% current derating per datasheet Note: IO must be reduced to 2.4A for capacitive-input operation. This accounts for higher peak currents and increased thermal stress caused by rapid capacitor charging at voltage peaks, which elevates junction temperature beyond resistive/inductive load conditions.

Does PR3001-T meet lead-free assembly requirements for reflow soldering?

Yes - PR3001-T features lead-free, RoHS-compliant tin-plated leads qualified per J-STD-020C moisture sensitivity Level 1. It supports standard SnPb and lead-free reflow profiles, including peak temperatures up to 260°C for ≤10 seconds, provided board-level thermal mass and preheat ramp rates comply with IPC-J-STD-020.
