Product details

Overview

UF1007-T from Diodes Incorporated is a 1000 V, 1.0 A ultra-fast recovery rectifier diode in DO-41 package, featuring 50 ns reverse recovery time, 1.7 V forward voltage at 1.0 A, and 30 A non-repetitive surge capability - used in high-frequency switch-mode power supplies and AC/DC front-end rectification.

For engineers reviewing the UF1007-T datasheet, UF1007-T pinout, UF1007-T application, or UF1007-T equivalent, key selection criteria include peak repetitive reverse voltage (1000 V), trr (50 ns), thermal resistance (95 K/W), forward voltage consistency at rated current, and UL 94V-0 flammability compliance for safety-critical power stages.

Technical Context

This diffused-junction silicon rectifier delivers ultra-fast switching performance optimized for high-efficiency SMPS, PFC stages, and offline DC adapters where low reverse recovery charge and minimal switching loss are critical. Its 50 ns trr and 20 pF junction capacitance at 4 V support operation up to several hundred kHz.

The device operates across –65 °C to +150 °C junction temperature range, with derated average current (1.0 A) specified at 55 °C ambient under defined lead length conditions. Reverse leakage remains ≤5 µA at 25 °C and ≤100 µA at 100 °C under full blocking voltage.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - supports direct rectification of 700 V RMS line inputs (e.g., 3-phase 400 V AC systems with transients)
I_O	1.0 A @ T_A = 55 °C - usable in compact open-frame adapters without forced airflow
t_rr	50 ns - enables efficient operation in 100–500 kHz SMPS topologies with reduced EMI and switching loss
V_FM	1.7 V @ I_F = 1.0 A - contributes to <1.7 W conduction loss per diode in bridge configurations
R_JA	95 K/W - requires minimum PCB copper area (≥1 cm²) for thermal management at full load
I_FSM	30 A (8.3 ms half-sine) - withstands inrush currents in AC-input circuits with NTC bypass or soft-start
C_j	20 pF @ 4 V, 1 MHz - limits capacitive coupling noise in high-dv/dt gate-drive or snubber-free designs

Pinout & Package

DO-41 axial-leaded plastic package with cathode band marking; leads are tin-plated, solderable per MIL-STD-202 Method 208; weight ≈ 0.35 g; mounting position unrestricted.

Pin/Terminal	Circuit Role	Design Meaning
Anode (unmarked end)	Forward current entry point	Connected to AC input or transformer secondary; must handle full surge current path
Cathode (banded end)	Forward current exit / reverse blocking node	Connected to bulk capacitor positive rail; defines voltage reference for downstream regulation

Key Features

Feature	Design Value
Ultra-fast recovery (50 ns)	Reduces reverse recovery charge (Q_rr) to minimize switching loss and EMI in high-frequency converters
Low V_F (1.7 V @ 1 A)	Improves system efficiency in 12–24 V output SMPS by lowering conduction loss vs. standard fast rectifiers
30 A surge rating	Supports reliable cold-start operation in universal-input AC/DC supplies without external inrush limiting
UL 94V-0 plastic case	Meets flame-retardancy requirements for Class II insulated power supplies and ITE end equipment
–65 °C to +150 °C operation	Enables deployment in automotive under-hood auxiliary supplies and industrial control power modules

Applications

AC/DC Adapter Front-End

Server PSU Input Rectification

Use Scenario: Universal-input (90–264 V AC) 65 W laptop adapter with active PFC stage.

IC Role / Device Role / Timing Role: Primary-side ultra-fast rectifier in voltage-doubler or bridge configuration feeding bulk capacitor.

Use Value: 50 ns t_rr minimizes switching loss during high-frequency PFC transitions, improving overall efficiency by ~0.5% over standard FR107.

Use Scenario: 1 kW redundant server power supply with dual AC inputs and hot-swap capability.

IC Role / Device Role / Timing Role: Input rectifier in full-wave bridge handling 115/230 V AC mains with transient overvoltage protection.

Use Value: 1000 V V_RRM ensures margin against 1.5× line surges (IEC 61000-4-5 Level 3), enabling robust field reliability.

Industrial Motor Drive DC Link

LED Driver Bulk Rectification

Use Scenario: 3 kW variable-frequency drive with 3-phase rectifier input feeding IGBT inverter stage.

IC Role / Device Role / Timing Role: DC link rectifier in six-pulse configuration operating at 50/60 Hz with harmonic filtering.

Use Value: Low R_JA (95 K/W) and 1.0 A continuous rating allow natural convection cooling on shared heatsink with control circuitry.

IC Role / Device Role / Timing Role: Bridge rectifier element in isolated flyback primary-side input stage.

Use Value: –65 °C to +150 °C T_j range supports operation in sealed, thermally constrained enclosures without derating.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R06	600 V V_RRM, 50 ns t_rr, 1.7 V V_F - lower voltage rating, same speed and VF	Not suitable for 1000 V systems; limited to 400 V AC inputs or lower	Select when cost sensitivity outweighs voltage margin and system uses ≤277 V AC input
ES1J	600 V V_RRM, 35 ns t_rr, 1.7 V V_F - faster recovery but lower blocking voltage	Better for >300 kHz resonant converters; insufficient for 1000 V transient immunity	Prefer for high-frequency LLC or QR flyback where trr < 40 ns is critical and voltage stress is < 420 V

Compared with UF1007-T, STTH1R06 trades 400 V blocking headroom for potential cost reduction, while ES1J improves switching speed at the expense of safe operating area in high-voltage AC line applications - neither offers drop-in replacement capability without circuit revalidation.

FAQ

What is the maximum allowable junction temperature for UF1007-T?

The absolute maximum junction temperature is +150 °C, with storage temperature matching this range. Operation at T_j > 125 °C requires careful thermal design due to accelerated IR increase; derating curves in Figure 1 define safe I_O limits versus ambient temperature and PCB copper area.

Can UF1007-T replace UF1006 in an existing design?

Yes, UF1007-T is a direct upgrade from UF1006 (800 V) with identical package, pinout, and thermal characteristics - offering 200 V higher V_RRM for improved surge margin without layout or thermal changes, provided board clearance meets IPC-2221 creepage requirements for 1000 V systems.

Is UF1007-T compliant with RoHS and REACH?

Yes, UF1007-T is RoHS 2011/65/EU and REACH SVHC-compliant, with lead-free matte tin-plated leads and halogen-free molding compound meeting IEC 61249-2-21 standards - documented in Diodes Incorporated's official material declarations.

Does UF1007-T require a heatsink in typical 1 A applications?

No heatsink is required at 1.0 A if ambient temperature stays ≤55 °C and PCB copper area ≥1 cm² is provided adjacent to leads; thermal resistance rises sharply below 9.5 mm lead length, so layout must follow datasheet Figure 1 derating curve and maintain specified lead-to-ambient spacing.
