Product details
Overview
UF4007-M3/54 from Vishay General Semiconductor is an ultrafast plastic rectifier diode in DO-41 package, rated for 1000 V peak reverse voltage, 1.0 A average forward current, and 50 ns reverse recovery time. It features glass-passivated junction, low 1.7 V forward voltage at 1.0 A, and high surge capability (30 A IFSM), designed for high-frequency freewheeling and output rectification in SMPS.
For engineers reviewing the UF4007-M3/54 datasheet, UF4007-M3/54 pinout, UF4007-M3/54 application, or UF4007-M3/54 equivalent, key selection criteria include VRRM = 1000 V, trr = 50 ns, VF = 1.7 V @ 1 A, TJ(max) = 150 °C, and DO-41 mechanical compatibility with standard through-hole layouts.
Technical Context
This single-diode rectifier uses a planar passivated silicon junction optimized for fast switching in DC-DC converters and offline switchers. Its 50 ns reverse recovery time enables operation up to several hundred kHz without excessive switching losses.
The device operates across -55 °C to +150 °C junction temperature range and maintains ≤10 μA reverse leakage at 25 °C and ≤50 μA at 100 °C under full-rated VRRM, supporting stable performance in thermally demanding power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - supports primary-side rectification in universal-input AC-DC adapters and industrial 800 V bus systems |
| IF(AV) | 1.0 A at 55 °C ambient with 0.375" lead length - suitable for medium-power secondary-side outputs up to ~12 W |
| trr | 50 ns - enables efficient operation in 200–500 kHz flyback and forward converters without snubber overhead |
| VF | 1.7 V @ 1.0 A - reduces conduction loss vs. standard recovery diodes, improving efficiency by ~0.5–1.2% in 12 V output rails |
| IFSM | 30 A @ 8.3 ms half-sine - withstands inrush and transient surges during cold-start or short-circuit recovery |
| CJ | 17 pF @ 4.0 V, 1 MHz - limits capacitive coupling noise in high dv/dt gate-drive or feedback paths |
Pinout & Package
Package: DO-41 (DO-204AL) - axial-leaded, glass-passivated plastic case with matte tin-plated leads; cathode indicated by color band; RoHS-compliant and halogen-free (M3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry | Connected to lower-potential node (e.g., transformer secondary center-tap or switch node return) |
| Cathode | Forward current exit / reverse blocking terminal | Marked with color band; ties to output capacitor positive or load return; blocks 1000 V reverse polarity |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables reliable operation at TJ = 150 °C and improves humidity resistance vs. epoxy-only passivation |
| Ultrafast 50 ns trr | Reduces reverse recovery charge (Qrr ≈ 15 nC), minimizing EMI and cross-conduction risk in synchronous designs |
| Low VF = 1.7 V @ 1 A | Lowers thermal rise in compact layouts; allows use without heatsinking in <15 W applications |
| 30 A IFSM rating | Supports robust startup behavior in constant-current LED drivers and battery charger front-ends |
| DO-41 mechanical standardization | Ensures drop-in replacement compatibility with legacy UF400x, 1N400x, and similar axial rectifiers |
Applications
| AC-DC Adapter Output Rectification | DC-DC Flyback Freewheeling Diode |
|---|---|
Use Scenario: Secondary-side rectification in 5–24 V, 5–12 W universal-input offline flyback adapters. IC Role / Device Role / Timing Role: Unidirectional current path converting transformer AC output to regulated DC; blocks reverse voltage during MOSFET on-time. Use Value: 50 ns trr minimizes switching loss and ringing; 1000 V VRRM accommodates reflected voltage spikes in high-turn-ratio designs. |
Use Scenario: Freewheeling path for energy stored in transformer leakage inductance during MOSFET off-time. IC Role / Device Role / Timing Role: Clamp inductive kickback and steer current to output capacitor; must recover before next switching cycle. Use Value: 50 ns trr ensures full recovery within typical 500 ns dead-time windows at 200 kHz, preventing shoot-through. |
| Industrial Power Supply Input Protection | LED Driver Bulk Rectification |
Use Scenario: Bridge input rectification in 24–48 V industrial PSUs handling 100–240 VAC input with high line transients. IC Role / Device Role / Timing Role: One leg of full-wave bridge; blocks reverse voltage during negative AC half-cycle. Use Value: 1000 V VRRM provides 2× margin over 700 V PIV requirement for 400 VAC systems with surge tolerance. |
Use Scenario: Bulk rectification feeding constant-current buck controller in outdoor LED streetlight drivers. IC Role / Device Role / Timing Role: Converts rectified AC to DC bus prior to high-frequency buck stage; handles 30 A surge during cold start. Use Value: 30 A IFSM rating sustains repeated inrush events without degradation; 150 °C TJ(max) supports sealed fixture thermal environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06U | TO-220AC package, 600 V VRRM, 50 ns trr, VF = 1.7 V @ 1 A | Higher thermal mass but larger footprint; requires heatsink above 0.5 A continuous | Preferred where board space permits and higher surge margin is needed beyond DO-41 lead-frame limits |
| ES1J-E3/54 | DO-214AA (SMA) package, 600 V VRRM, 35 ns trr, VF = 1.7 V @ 1 A | Surface-mount alternative with faster recovery but lower VRRM and reduced surge rating (25 A) | Used when automated assembly and higher frequency (>1 MHz) operation are prioritized over 1000 V isolation |
Compared with UF4007-M3/54, STTH1R06U offers superior thermal dissipation but demands PCB real estate and mounting hardware, while ES1J-E3/54 enables miniaturized SMT layouts at the cost of peak voltage capability and surge robustness-making UF4007-M3/54 optimal for cost-sensitive, high-VRRM through-hole power supplies.

FAQ
What is the maximum junction temperature rating for UF4007-M3/54?
The UF4007-M3/54 has a maximum operating junction temperature of +150 °C, verified per Vishay's thermal characterization in Document Number 88755. This rating allows sustained operation in enclosed power supplies and high-ambient environments when derated per the IF(AV) derating curve. The device maintains specified electrical parameters up to this limit, provided thermal resistance to ambient (RθJA = 60 °C/W) is managed via adequate lead length and PCB copper area.
Is UF4007-M3/54 compatible with lead-free soldering processes?
Yes, UF4007-M3/54 supports lead-free reflow and wave soldering per J-STD-002 and JESD 22-B102 standards. Its matte tin-plated leads withstand solder dip at 275 °C for up to 10 seconds, and the M3 suffix confirms halogen-free, RoHS-compliant construction. No special preheat or cooling profiles are required beyond standard Pb-free process guidelines.
How does the reverse recovery time of UF4007-M3/54 compare to standard rectifiers like 1N4007?
UF4007-M3/54 has a specified trr of 50 ns, whereas the 1N4007 exhibits trr > 2000 ns. This 40× faster recovery significantly reduces switching losses and EMI generation in high-frequency converters. In practice, replacing 1N4007 with UF4007-M3/54 in a 200 kHz flyback improves efficiency by 0.8–1.5% and eliminates need for RC snubbers in many cases.
What is the meaning of the "M3" and "54" suffixes in UF4007-M3/54?
The "M3" suffix denotes halogen-free, RoHS-compliant construction meeting JEDEC JESD201 Class 1A whisker resistance requirements. The "54" indicates the preferred packaging code for 13-inch diameter paper tape and reel, containing 5500 units per reel-standard for automated SMT placement despite UF4007-M3/54 being an axial-leaded part adapted for tape-and-reel handling.
Can UF4007-M3/54 be used in place of UF4006 or UF4005 in an existing design?
UF4007-M3/54 is mechanically and electrically pin-compatible with UF4006 and UF4005, sharing identical DO-41 package, pinout, and thermal characteristics. The only difference is VRRM: UF4007-M3/54 is rated for 1000 V versus 800 V (UF4006) and 600 V (UF4005). Substitution is safe if the circuit's peak reverse voltage remains ≤1000 V and no derating is required for reliability margin.
