Product details
Overview
UPR60/TR7 from Microsemi is an ultra-fast recovery surface-mount rectifier diode in Powermite package, rated for 600V reverse voltage, 2A average forward current, and 30ns reverse recovery time. It serves as a high-frequency switching rectifier in offline SMPS and DC-DC converters where low reverse recovery loss and thermal efficiency are critical.
For engineers reviewing the UPR60/TR7 datasheet, UPR60/TR7 pinout, UPR60/TR7 application, or UPR60/TR7 equivalent, this device is selected for high-efficiency AC/DC front-ends, charge pump topologies, and space-constrained SMT power stages requiring reliable 600V blocking and fast turn-off behavior.
Technical Context
The UPR60/TR7 employs a planar epitaxial silicon structure optimized for ultra-fast soft recovery, minimizing switching noise and EMI in high-frequency converters. Its 30ns trr is measured under standardized conditions (IF = 0.5A, IR = 1.0A, IREC = 0.25A), and its low 1.4V typical VF at 1.2A reduces conduction loss at elevated temperatures.
Thermal performance is enhanced by the Powermite package's full metallic bottom (RθJ-BOT = 10°C/W) and integral locking tab acting as a heat sink (RθJ-TAB = 30°C/W when mounted on 2 oz copper). The device operates across –55°C to +150°C, supporting industrial and automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Reverse Voltage | 600V - supports universal-input AC/DC designs up to 400V DC bus with safety margin |
| Avg Forward Current | 2A - delivers continuous output power up to ~20W in compact SMT layouts without forced cooling |
| Reverse Recovery Time | 30ns - enables operation at ≥100kHz switching frequencies with minimal tail current loss |
| Forward Voltage | 1.4V typ @ 1.2A, 25°C - lowers I²R losses and improves efficiency vs. standard FRDs |
| Thermal Resistance J–Bottom | 10°C/W - allows direct PCB copper pad conduction cooling, reducing need for external heatsinks |
| Surge Current | 20A non-repetitive (8.3ms) - withstands inrush and transient overloads in power supply startup |
Pinout & Package
UPR60/TR7 uses the Powermite surface-mount package: a molded plastic body with full metallic bottom and integral locking tab for mechanical retention and thermal transfer. Dimensions: 6.10 × 4.20 × 1.90 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for forward conduction path | Connected to primary-side switch node or transformer secondary in flyback/forward topologies |
| Cathode | Output terminal for forward conduction path | Connected to output capacitor or LC filter input; polarity defines rectification direction |
| Metallic Bottom / Tab | Thermal and mechanical interface | Electrically isolated but thermally conductive; soldered directly to large copper pour for heat dissipation |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-2EY60 | Same 600V VRRM, 2A IF(AV), but 35ns trr; TO-277 package with exposed cathode tab | Higher thermal resistance (RθJ-CASE = 40°C/W); requires thermal pad under cathode only | Preferred where TO-277 footprint compatibility exists and slightly relaxed recovery time is acceptable |
| ON Semiconductor MUR260 | 600V VRRM, 2A IF(AV), 35ns trr; SMA package with plastic body and no metallic bottom | No integrated heatsink tab; RθJ-PCB ≈ 65°C/W limits power density in compact layouts | Suitable for cost-sensitive, lower-power (<10W) designs where board space and thermal budget allow larger copper area |
Compared with VS-2EY60 and MUR260, the UPR60/TR7 delivers superior thermal performance via its full metallic bottom and locking tab, enabling higher power density in space-constrained SMT applications without sacrificing 30ns recovery speed or 600V ruggedness.

FAQ
What is the maximum junction temperature rating for UPR60/TR7?
The UPR60/TR7 has a specified operating and storage temperature range of –55°C to +150°C. Its absolute maximum junction temperature is 150°C, validated under conditions where the tab temperature is maintained at ≤75°C and mounted on a PCB with 2 oz copper. Derating is required above 75°C tab temperature per the thermal resistance values in the datasheet.
Does UPR60/TR7 have a SPICE model available?
Yes, a verified SPICE model for UPR60/TR7 is provided in the official Microsemi datasheet MSC1597.PDF. It includes parameters such as IS = 1.88nA, N = 1.6, RS = 0.133Ω, TT = 62ns, BV = 600V, and CJO = 25pF - enabling accurate simulation of forward conduction, reverse recovery, and breakdown behavior in circuit-level analysis.
Is UPR60/TR7 pin-compatible with other Powermite rectifiers?
Yes, UPR60/TR7 shares the same Powermite package footprint and terminal configuration (anode/cathode/metallic bottom) with other members of Microsemi's Powermite ultra-fast rectifier series, including UPR30/TR7 and UPR40/TR7. Mechanical and thermal interfaces remain identical; only voltage and current ratings differ between variants.
What is the significance of the "TR7" suffix in UPR60/TR7?
The "TR7" suffix denotes tape-and-reel packaging with 7-inch reels, standard for SMT assembly. UPR60/TR7 is supplied in moisture-sensitive packaging compliant with J-STD-020, with quantity per reel specified in Microsemi's ordering information - confirming its readiness for high-volume automated placement without manual handling or dry-pack requirements.
How does the Powermite package improve manufacturability versus traditional SMD diodes?
The Powermite package of UPR60/TR7 improves manufacturability through its full metallic bottom (preventing solder flux entrapment) and integral locking tab (ensuring secure retention during pick-and-place). These features eliminate tombstoning risk and enable reliable reflow soldering on fine-pitch PCBs without adhesive or secondary fixturing - a key advantage over SMA or SOD-123 packages.
