Product details

Overview

UF3007-T from Diodes Incorporated is an ultra-fast recovery rectifier diode in DO-201AD package, rated for 1000 V peak repetitive reverse voltage, 3.0 A average forward current at 55°C ambient, and 50 ns reverse recovery time. It delivers low forward voltage drop (1.7 V at 3.0 A), low reverse leakage (5.0 µA at 25°C), and withstands 150 A non-repetitive surge current - used in high-frequency switch-mode power supplies and AC/DC front-end rectification.

For engineers reviewing the UF3007-T datasheet, UF3007-T pinout, UF3007-T application, or UF3007-T equivalent, key selection criteria include reverse voltage rating, trr performance under high-frequency switching, thermal resistance (35 °C/W), surge robustness, and RoHS-compliant lead-free plating for reflow compatibility.

Technical Context

This device employs a diffused junction structure to achieve ultra-fast recovery with minimal minority carrier storage, enabling efficient operation in 50–500 kHz SMPS topologies. Its 1000 V V_RRM supports universal-input offline designs, while the 50 ns t_rr reduces switching losses compared to standard recovery rectifiers.

The DO-201AD package provides mechanical robustness and thermal dissipation suitable for through-hole mounting in industrial power supplies. Cathode band polarity marking and tin-plated leads ensure reliable solderability per MIL-STD-202, Method 208.

Key Specifications

V_RRM	1000 V - Supports full-wave rectification of 700 V RMS line inputs with safety margin.
I_O	3.0 A @ T_A = 55°C - Sustains continuous output in compact heatsinkless adapters up to ~45 W.
t_rr	50 ns - Enables high-frequency operation with reduced EMI and switching loss vs. 500 ns standard rectifiers.
V_F	1.7 V @ I_F = 3.0 A - Limits conduction loss to ~5.1 W at full load, easing thermal design.
R_θJA	35 °C/W - Junction-to-ambient thermal resistance enables 125°C max T_J with ≤90°C case rise.
I_FSM	150 A (8.3 ms half-sine) - Withstands cold-start inrush and transient surges without failure.

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultra-fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MURS320	200 V V_RRM, 3.0 A, 35 ns t_rr, SMC package	Limited to lower-voltage DC-DC inputs; not suitable for 1000 V line applications	Select only when system V_RRM requirement ≤200 V and surface-mount layout is mandatory.
US3M	1000 V V_RRM, 3.0 A, 75 ns t_rr, DO-214AB package	Slower recovery increases switching loss in >100 kHz designs; different footprint	Acceptable where cost is critical and t_rr < 60 ns is not required; requires PCB pad revision.

Compared with MURS320 and US3M, UF3007-T uniquely balances 1000 V blocking, 50 ns speed, and through-hole DO-201AD reliability - making it optimal for cost-sensitive, high-voltage, high-frequency adapter and industrial SMPS designs where thermal margin and surge immunity are prioritized.

FAQ

What is the maximum operating temperature for UF3007-T?

The UF3007-T has an operating junction temperature range of –65°C to +150°C. Its thermal resistance is 35°C/W junction-to-ambient, so with 3.0 A forward current and 1.7 V drop, power dissipation is ~5.1 W - requiring ≤90°C ambient to stay within 150°C T_J limit under natural convection.

Is UF3007-T compatible with lead-free reflow soldering?

Yes. UF3007-T features tin-plated leads compliant with RoHS and qualified for Pb-free reflow processes, including peak temperatures up to 260°C per JEDEC J-STD-020. Its DO-201AD package is rated for moisture sensitivity level 1, eliminating bake requirements before assembly.

How does UF3007-T differ from UF3004 in practical design?

UF3007-T offers 1000 V V_RRM versus UF3004's 400 V, enabling use in higher-line applications without series stacking. Both share identical 3.0 A I_O, 50 ns t_rr, and DO-201AD package - but UF3007-T's higher voltage rating adds 250% margin for transient suppression in unregulated mains inputs.

Can UF3007-T be used in place of a standard 1N4007?

No - although both are DO-201AD rectifiers, UF3007-T is ultra-fast (50 ns t_rr) versus 1N4007's 30 µs recovery. Substituting in 50/60 Hz linear supplies causes no issue, but in high-frequency SMPS, UF3007-T prevents destructive reverse recovery current spikes and EMI that 1N4007 cannot suppress.
