Product details
Overview
UPR15E3/TR13 from Microsemi is a 2.5 A, 150 V peak reverse voltage 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 serves as a high-frequency output rectifier in compact switching power supplies.
For engineers reviewing the UPR15E3/TR13 datasheet, UPR15E3/TR13 pinout, UPR15E3/TR13 application, or UPR15E3/TR13 equivalent, key selection criteria include VRWM = 150 V, trr = 25 ns, VF = 0.975 V @ 2.0 A, RθJC = 10 °C/W, and DO-216 surface-mount compatibility with automatic insertion equipment.
Technical Context
The UPR15E3/TR13 is a planar epitaxial silicon ultrafast recovery rectifier optimized for high-frequency DC/DC conversion. Its 25 ns trr and low IRM minimize reverse recovery losses, while the full metallic bottom and locking tab enable efficient heat conduction to the PCB mounting plane.
Rated for 2.5 A average rectified current at TC = 75 °C and 150 V working peak reverse voltage, it operates across –55 °C to +150 °C junction temperature range. The DO-216 package delivers 8.45 mm² footprint and 1 mm max height for space-constrained layouts.

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-M3/54 | Same DO-216 package, 150 V VRWM, 2.5 A IF(AV), but trr = 35 ns and VF = 1.05 V @ 2 A | Higher VF and slower trr increase conduction and switching losses in >200 kHz designs | Acceptable where efficiency margin >3% exists and layout allows minor thermal derating |
| ON Semiconductor MUR220SFT1G | TO-220AC package, 200 V VRWM, 2 A IF(AV), trr = 35 ns, VF = 0.93 V @ 2 A | Larger footprint and through-hole mounting incompatible with automated SMT lines | Only suitable for legacy through-hole designs requiring higher VRWM; not drop-in compatible |
Compared with VS-2EY15-M3/54 and MUR220SFT1G, the UPR15E3/TR13 offers superior high-frequency performance (25 ns trr) and lower thermal resistance (10 °C/W vs. ~25–30 °C/W), enabling higher power density in SMT-based compact power supplies without forced cooling.

FAQ
What is the maximum working peak reverse voltage rating for UPR15E3/TR13?
The UPR15E3/TR13 has a maximum working peak reverse voltage (VRWM) of 150 V. This rating defines the highest repetitive reverse voltage the device can block continuously without breakdown. It is validated per Microsemi's absolute maximum ratings table and applies across the full operating temperature range of –55 °C to +150 °C junction temperature.
Does UPR15E3/TR13 support automated SMT assembly?
Yes, UPR15E3/TR13 is fully compatible with automated surface-mount insertion equipment. Its DO-216 package features a unique locking tab and full metallic bottom that prevent solder flux entrapment and ensure reliable placement and reflow. The 1 mm max height and 8.45 mm² footprint meet standard pick-and-place and stencil requirements.
What is the forward voltage drop of UPR15E3/TR13 at rated current?
The forward voltage drop (VF) of UPR15E3/TR13 is 0.975 V at IF = 2.0 A and TJ = 25 °C. At elevated temperature (TJ = 100 °C), VF decreases to 0.895 V due to silicon's negative temperature coefficient. These values are measured using short-duration pulses to avoid self-heating effects, per the official Microsemi electrical parameters table.
How does the thermal performance of UPR15E3/TR13 compare to standard SOD-123 devices?
UPR15E3/TR13 achieves RθJC = 10 °C/W - significantly lower than typical SOD-123 rectifiers (~25–35 °C/W) - due to its full metallic bottom and integral locking tab acting as a direct thermal path to the PCB. This enables higher sustained current in thermally constrained layouts without heatsinks or airflow.
Is UPR15E3/TR13 RoHS compliant and what plating is used?
Yes, UPR15E3/TR13 is RoHS compliant, indicated by the "e3" suffix. It uses annealed matte-tin plating over copper, qualified per MIL-STD-750 Method 2026 for solderability. The plating ensures compatibility with lead-free reflow profiles and eliminates concerns about tin whisker formation in long-life industrial deployments.
