Product details
Overview
UPR15E3/TR7 from Microsemi is a 2.5 A, 150 V surface-mount ultrafast rectifier in DO-216 (SOD-123FL) package, featuring 25 ns reverse recovery time, 0.975 V forward voltage at 2.0 A, and 10 °C/W junction-to-case thermal resistance. It delivers high-efficiency rectification in high-frequency switching power supplies and charge pump circuits.
For engineers reviewing the UPR15E3/TR7 datasheet, UPR15E3/TR7 pinout, UPR15E3/TR7 application, or UPR15E3/TR7 equivalent, key selection criteria include its 150 V peak reverse voltage rating, low-profile 1 mm height, RoHS-compliant e3 matte-tin plating, and compatibility with automated insertion equipment.
Technical Context
This discrete diode operates as a unidirectional high-speed rectifier with optimized forward conduction and minimal reverse recovery loss. Its DO-216 package integrates a full metallic bottom and locking tab to achieve 10 °C/W RθJC, enabling efficient heat transfer to the PCB mounting plane without external heatsinks.
The device sustains non-repetitive surge currents up to 25 A (8.3 ms half-sine), supports continuous operation at TJ = –55 to +150 °C, and maintains IR ≤ 2.0 µA at VRWM = 150 V and TJ = 25 °C - critical for low-leakage DC-DC stage isolation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-2EY15-M3/5AT | Same DO-216 package, 150 V VRWM, but 35 ns trr and 1.1 V VF at 2 A | Higher conduction loss and slower recovery limit use in >300 kHz designs | Acceptable where cost sensitivity outweighs efficiency at high frequency |
| ON Semiconductor MUR220SFT1G | SOD-123FL package, 200 V VRWM, 30 ns trr, 1.05 V VF at 2 A, higher RθJA (280 °C/W) | Wider voltage margin but inferior thermal performance limits 2.5 A operation without enhanced layout | Preferred when system requires >150 V blocking but cannot accommodate larger footprint |
Compared with VS-2EY15-M3/5AT and MUR220SFT1G, UPR15E3/TR7 offers the lowest combined VF/trr product (24.4 V·ns) and best thermal resistance (10 °C/W), making it optimal for thermally constrained, high-frequency rectification where efficiency and reliability are prioritized over voltage headroom or cost.

FAQ
What is the peak reverse voltage rating of the UPR15E3/TR7?
The UPR15E3/TR7 has a working peak reverse voltage (VRWM) rating of 150 V. This value is specified per Microsemi's absolute maximum ratings table and defines the maximum sustained reverse-bias voltage the device can block without breakdown under normal operating conditions. Exceeding this voltage risks irreversible avalanche failure.
Does the UPR15E3/TR7 meet RoHS requirements?
Yes, the UPR15E3/TR7 is RoHS compliant and carries the "e3" suffix indicating matte-tin plating per JEDEC J-STD-609. Its finish meets MIL-STD-750 Method 2026 solderability standards and contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE substances above threshold limits.
What is the thermal resistance from junction to case for the UPR15E3/TR7?
The UPR15E3/TR7 has a junction-to-case (bottom) thermal resistance (RθJC) of 10 °C/W. This value is measured with the case bottom mounted to a copper plane and reflects the device's optimized thermal path via its full metallic bottom and locking tab - enabling direct PCB heat sinking without added thermal interface material.
Is the UPR15E3/TR7 suitable for automated assembly processes?
Yes, the UPR15E3/TR7 is designed for compatibility with automatic insertion equipment. Its DO-216 package features a unique locking tab and symmetrical terminal geometry that ensures reliable pick-and-place placement and consistent solder joint formation during reflow, as confirmed in Microsemi's mechanical packaging documentation.
What is the reverse recovery time specification for the UPR15E3/TR7?
The UPR15E3/TR7 has a reverse recovery time (trr) of 25 ns, tested at IF = 0.5 A, IR = 1.0 A, and IREC = 0.25 A. This ultrafast recovery characteristic minimizes switching loss and EMI in high-frequency power converters operating above 100 kHz, distinguishing it from standard fast recovery diodes with trr > 50 ns.
