Product details
Overview
UF5JD1-13 from Diodes Incorporated is a 600 V, 5 A ultra-fast recovery surface-mount rectifier in TO252 (DPAK) package, optimized for freewheeling and clamping in switching power supplies. It delivers 15 ns reverse recovery time, 3.0 V max forward voltage at 5 A/25°C, and 30 µA reverse leakage at 600 V/25°C, enabling high-efficiency operation in SMPS and PFC stages.
For engineers reviewing the UF5JD1-13 datasheet, UF5JD1-13 pinout, UF5JD1-13 application, or UF5JD1-13 equivalent, key selection criteria include reverse recovery charge (5 nC), thermal resistance junction-to-case (18 °C/W on FR4), soft-switching behavior, and TO252-compatible PCB layout requirements for thermal management in compact power converters.
Technical Context
This ultra-fast recovery rectifier employs a planar epitaxial silicon structure with controlled carrier lifetime to achieve soft reverse recovery-minimizing EMI and voltage overshoot during turn-off. Its 600 V blocking capability supports universal-input AC/DC front-ends and boost PFC topologies operating in both discontinuous (DCM) and continuous conduction mode (CCM).
The device is characterized for 80 A non-repetitive surge current (8.3 ms half-sine), enabling robust handling of inrush and transient overloads. Thermal performance is specified for two mounting conditions: 18 °C/W RθJC on FR4 PCB (Note 5) and 2 °C/W RθJC on 2-inch Al substrate (Note 6), reflecting its dual-use suitability for cost-sensitive consumer designs and thermally demanding industrial applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Supports universal AC input (85–265 VAC) rectification without derating in standard boost PFC designs. |
| IO | 5 A average - Sustains continuous output current in 65–100 W SMPS secondary-side rectification or primary-side snubber/clamp paths. |
| tRR | 15 ns typical - Enables >300 kHz switching frequencies with low switching loss and minimal di/dt-induced ringing. |
| QRR | 5 nC typical - Reduces turn-on loss in synchronous rectifier-assisted topologies and limits EMI generation in high-dV/dt environments. |
| VF | 3.0 V max at 5 A/25°C - Defines conduction loss ceiling in thermal budget calculations for TO252-mounted layouts. |
| RθJC | 18 °C/W (FR4) - Requires ≥4.57 mm × 1.06 mm copper pad per Diodes' recommended layout to maintain TJ < 150°C at full load. |
| IR | 30 µA max at 600 V/25°C - Ensures low standby power loss in energy-efficient adapters meeting Level VI efficiency standards. |
Pinout & Package
Package: TO252 (DPAK), surface-mount, single-die rectifier with exposed drain tab (cathode-connected thermal pad). Molded green compound, UL 94V-0 rated, lead-free and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Left) | Anode | Input terminal for forward current flow; must be routed with low-inductance trace in high-di/dt clamp circuits. |
| Pin 2 (Center) | Cathode / Heat Sink Tab | Electrically connected to cathode and serves as primary thermal path; requires soldered copper area ≥4.57 mm × 1.06 mm for rated current. |
| Pin 3 (Right) | Anode | Second anode connection-pins 1 and 3 must be electrically joined on PCB to distribute current and reduce bond wire stress. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast soft recovery | 15 ns tRR with low Irr/QRR ratio minimizes voltage spikes and EMI in high-frequency flyback and LLC resonant converters. |
| Low forward voltage | 3.0 V max at 5 A enables <1.5 W conduction loss at full load, reducing heatsink requirements in space-constrained adapters. |
| High surge rating | 80 A IFSM withstands repeated cold-start surges in AC/DC power supplies without degradation. |
| Green packaging | Halogen- and antimony-free molding compound (<900 ppm Br+Cl, <1000 ppm Sb) meets global environmental compliance mandates. |
Applications
| SMPS Secondary Rectification | Boost PFC Clamp Diode |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06 | Same 600 V/5 A rating but 35 ns tRR, higher VF (1.7 V typ @ 5 A), TO220AC package. | Requires heatsink and larger board area; less suitable for high-frequency, space-constrained SMPS. | Select when legacy TO220 footprint compatibility is required and thermal mass can absorb slower recovery. |
| MBR560F | 60 V VRRM, Schottky construction, 0.72 V VF @ 5 A, TO277 package. | Only viable in low-voltage DC-DC outputs; cannot replace UF5JD1-13 in 400 V bus applications. | Choose only for secondary-side 12 V/5 A synchronous rectification where 600 V blocking is unnecessary. |
Compared with STTH5L06 and MBR560F, UF5JD1-13 uniquely balances 600 V capability, 15 ns recovery, and TO252 thermal efficiency-making it optimal for modern compact, high-frequency AC/DC converters where board space, EMI, and thermal resistance are co-constrained.

FAQ
What is the maximum allowable junction temperature for UF5JD1-13?
The absolute maximum junction temperature is +150°C, with derating beginning at +25°C ambient. At 5 A DC current on FR4 PCB (RθJA = 80 °C/W), power dissipation reaches ~15 W, requiring careful thermal pad design to keep TJ within limit. The device is rated for continuous operation up to this temperature when mounted per Diodes' recommended pad layout.
Can UF5JD1-13 be used in place of a standard fast recovery diode like UF4007?
Yes, but with critical trade-offs: UF5JD1-13 offers lower tRR (15 ns vs. 75 ns) and higher IO (5 A vs. 1 A), making it superior in high-frequency, high-current applications. However, its VF is higher (3.0 V vs. 1.7 V), increasing conduction loss. It is not a drop-in replacement due to TO252 vs. DO-41 package and different thermal interface requirements.
Does UF5JD1-13 require a heatsink on standard FR4 PCB?
No external heatsink is required if the PCB implements Diodes' recommended TO252 pad layout (4.57 mm × 1.06 mm copper area under the tab). With that, RθJC = 18 °C/W allows full 5 A operation at +70°C ambient while maintaining TJ ≤ 150°C. Smaller pads or no thermal copper will exceed junction limits under sustained load.
Is UF5JD1-13 suitable for automotive applications?
UF5JD1-13 is not AEC-Q101 qualified and lacks automotive-specific qualification testing (e.g., HTOL, temperature cycling). While its -65°C to +150°C operating range covers automotive under-hood temperatures, Diodes does not endorse it for safety-critical or mission-critical vehicle systems. It may be used in non-safety automotive accessories (e.g., infotainment power supplies) subject to full customer validation.
