Diodes Incorporated UF2007-T

Overview

UF2007-T from Diodes Incorporated is a 1000V, 2.0A ultra-fast rectifier diode in DO-15 package, featuring 50ns reverse recovery time, 1.7V forward voltage at 2.0A, and 60A non-repetitive surge capability. It serves as primary-side AC/DC input rectifier in offline SMPS, LED drivers, and industrial power supplies where high-voltage blocking and fast switching reduce switching losses.

For engineers reviewing the UF2007-T datasheet, UF2007-T pinout, UF2007-T application, or UF2007-T equivalent, key selection criteria include peak repetitive reverse voltage (1000V), average forward current derating above +50°C, thermal resistance (50°C/W), and low reverse leakage (<5.0µA at 25°C) for high-reliability power conversion designs.

Technical Context

This discrete silicon PN-junction rectifier uses diffused junction technology to achieve ultra-fast recovery (50ns) with low stored charge, enabling efficient operation in 50–100kHz switch-mode topologies. Its 1000V V_RRM rating supports universal-input (85–265V_AC) and high-line industrial applications without series stacking.

The device exhibits low reverse leakage (5.0µA @ 25°C, 100µA @ 100°C) and typical junction-to-ambient thermal resistance of 50°C/W under standard PCB mounting (9.5mm lead length), allowing direct integration into compact, convection-cooled power stages.

FAQ

Is UF2007-T still in active production?

No-UF2007-T is officially obsolete and discontinued per Diodes' DS25007 Rev. 5 (May 2023). Aetrix Electronics maintains limited legacy stock for design continuity and last-time buys, with full traceability and documentation. No new wafer fabrication or packaging is scheduled.

What is the maximum operating temperature for UF2007-T in free-air conditions?

The junction temperature limit is +150°C, but the average forward current derates linearly above +50°C ambient. At +70°C ambient, the usable I_O drops to ~1.5A; at +100°C, it falls to ~0.8A, assuming standard DO-15 mounting with 9.5mm lead length per datasheet Fig. 1.

Can UF2007-T replace UF2006-T in an existing design?

Yes-UF2007-T is a direct upgrade from UF2006-T (800V) with identical DO-15 package, pinout, and thermal characteristics. The 200V increase in V_RRM adds margin against line surges and simplifies safety certification for 300V+ DC bus applications without layout changes.

Does UF2007-T meet automotive qualification standards?

No-UF2007-T is not AEC-Q101 qualified. While Diodes offers automotive-grade versions (e.g., part numbers ending in "-Q"), this specific DO-15 variant is intended for industrial and commercial power applications. Automotive use requires explicit AEC-Q101 validation and PPAP documentation.
