Product details
Overview
UG06A from Taiwan Semiconductor is a single-die ultrafast rectifier diode rated for 50 V repetitive peak reverse voltage (VRRM), 0.6 A average forward current (IF), and 40 A non-repetitive surge current (IFSM), optimized for high-efficiency DC-DC converters and switching-mode power supplies operating at elevated temperatures.
For engineers reviewing the UG06A datasheet, UG06A pinout, UG06A application, or UG06A equivalent, key selection criteria include its 15 ns reverse recovery time (trr), 0.95 V max forward voltage at 0.6 A, 5 µA max reverse leakage at 25°C, TS-1 surface-mount package, and AEC-Q101 qualification availability in H-suffix variants.
Technical Context
The UG06A employs a planar epitaxial silicon junction structure engineered for ultrafast recovery (trr ≤ 15 ns) under IF = 0.5 A / IR = 1.0 A / Irr = 0.25 A test conditions, enabling high-frequency switching with minimal switching loss. Its thermal design supports continuous operation up to TJ = 150°C with RθJL = 28°C/W and RθJA = 97°C/W.
It features pure tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 molding compound, and cathode polarity indicated by a band. The TS-1 package is optimized for automated SMT assembly and thermal dissipation in compact power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum reverse blocking voltage before breakdown; defines usable input voltage range in flyback or buck-derived topologies |
| IF | 0.6 A - Continuous average forward current rating at TA = 25°C; derates linearly above 25°C per Fig.1 |
| trr | 15 ns - Measured reverse recovery time under standardized IF/IR/Irr conditions; enables >1 MHz switching without excessive loss |
| VF (max) | 0.95 V @ 0.6 A, 25°C - Forward conduction loss contributor; directly impacts conduction efficiency and thermal load |
| RθJL | 28 °C/W - Junction-to-lead thermal resistance; critical for estimating die temperature rise when mounted on PCB copper |
| IR (max) | 5 µA @ 25°C - Reverse leakage current at rated VR; low value ensures minimal standby power loss in high-impedance circuits |
Pinout & Package
TS-1 package: surface-mount, single-anode/single-cathode configuration with cathode identified by molded band; lead finish: pure tin, RoHS-compliant, J-STD-002 solderable; weight ≈ 0.200 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in boost/flyback); must handle full IF and IFSM |
| Cathode | Forward current exit point | Marked by band; connects to output rail or filter capacitor; carries same current as anode with polarity-dependent voltage drop |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery (trr ≤ 15 ns) | Enables high-frequency operation (>500 kHz) with reduced switching loss and EMI generation in SMPS |
| Low VF (0.95 V max @ 0.6 A) | Minimizes conduction loss and self-heating in space-constrained 0.6 A power paths |
| High TJ max (150°C) | Supports reliable operation in thermally demanding environments such as automotive under-hood or industrial enclosures |
| TS-1 package with tin-plated leads | Ensures robust SMT reflow compatibility, whisker resistance (JESD201 Class 2), and long-term solder joint integrity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH06S05W (STMicroelectronics) | Same VRRM (50 V), IF (0.6 A), but trr = 25 ns (slower); VF = 0.92 V typ | Higher trr increases switching loss in >1 MHz designs; suitable for <500 kHz converters | Select if cost sensitivity outweighs ultrafast performance need and layout allows minor thermal margin increase |
| MBR0550 (ON Semiconductor) | Schottky construction: VF = 0.55 V typ, but VRRM = 50 V, IR = 100 µA @ 25°C (higher leakage) | Lower VF improves light-load efficiency, but higher IR limits high-temp reliability in sealed systems | Prefer for low-VF priority in ambient-temperature applications; avoid where TJ > 100°C or standby current <10 µA required |
Compared with STTH06S05W and MBR0550, the UG06A delivers superior high-frequency switching efficiency via its 15 ns trr while maintaining low leakage and 150°C operation-making it optimal for thermally constrained, high-switching-frequency power stages where Schottky leakage or slower recovery are unacceptable.

FAQ
What is the maximum junction temperature rating for the UG06A?
The UG06A has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows continuous operation in high-ambient environments such as enclosed power supplies or automotive under-dash locations. Thermal design must ensure actual die temperature remains below this limit using RθJL = 28°C/W and appropriate PCB copper area.
Does the UG06A have AEC-Q101 qualification?
The base UG06A is not AEC-Q101 qualified; however, the variant UG06AH (with "H" suffix) is explicitly qualified per AEC-Q101 Rev D. This distinction is defined in the ordering information section: "H" means AEC-Q101 qualified. For automotive applications requiring stress-tested reliability, UG06AH-not UG06A-must be specified and sourced.
What is the reverse recovery time (trr) specification for the UG06A?
The UG06A has a maximum reverse recovery time (trr) of 15 ns, measured under standardized conditions: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A. This ultrafast recovery enables efficient operation in switching power supplies operating above 500 kHz, reducing switching losses and associated EMI compared to standard fast recovery diodes.
What package type does the UG06A use, and what are its mounting characteristics?
The UG06A uses the TS-1 surface-mount package-a compact, gull-wing leaded outline with pure tin-plated terminals. It is compatible with standard reflow profiles per J-STD-002, meets JESD201 Class 2 whisker resistance, and features UL 94V-0 flammability-rated molding compound. Polarity is marked by a cathode band on the body.
How does the forward voltage (VF) of the UG06A compare to Schottky alternatives like MBR0550?
The UG06A has a maximum VF of 0.95 V at 0.6 A and 25°C, higher than Schottky diodes such as MBR0550 (VF ≈ 0.55 V). However, the UG06A's silicon PN junction provides significantly lower reverse leakage (5 µA vs. 100 µA for MBR0550 at 25°C), enabling better high-temperature stability and lower standby loss in thermally demanding applications.
