Product details
Overview
UPS340/TR13 from Microsemi is a 3 A, 40 V Schottky barrier rectifier in Powermite3® SMT package, featuring low forward voltage (0.46 V typ. @ 3 A, 25°C), ultrafast switching with no reverse recovery, and full metallic bottom for flux-free soldering-used in high-frequency DC/DC converters and compact AC/DC adapters.
For engineers reviewing the UPS340/TR13 datasheet, UPS340/TR13 pinout, UPS340/TR13 application, or UPS340/TR13 equivalent, key selection criteria include VF consistency across temperature, IRM < 500 µA @ 40 V/25°C, thermal resistance of 2.5°C/W (junction-to-bottom, 2 oz Cu), and compatibility with automated SMT placement equipment.
Technical Context
This Schottky rectifier uses guard ring die construction to suppress transient-induced breakdown and eliminate reverse recovery charge-critical for high-efficiency synchronous rectification and charge pump topologies operating above 100 kHz. Its silicon Schottky junction delivers zero reverse recovery time and low stored charge (Qrr not specified, but inherent to Schottky architecture).
The Powermite3® package integrates locking tabs acting as internal heat sinks and a full metallic bottom that ensures direct thermal path to PCB copper, enabling 3 A continuous current at Tc = 100°C with minimal derating when mounted on 2 oz Cu land patterns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Reverse Voltage | 40 V - supports 36 V nominal input rails with 10% margin; rated for 28 V RMS input. |
| Forward Current (Avg) | 3 A - sustained DC output capability with thermal management via bottom-side conduction. |
| Forward Voltage | 0.46 V typ. @ 3 A, 25°C - reduces conduction loss by ~30% vs. standard PN diodes in 5–12 V output stages. |
| Reverse Leakage | 15 µA max @ 40 V, 25°C - enables low standby power in always-on auxiliary supplies. |
| Junction-to-Bottom Rθ | 2.5°C/W - requires only 2 oz Cu pad area (0.075" × 1.0") for cathode to achieve effective thermal coupling. |
| Capacitance | 180 pF @ 4 V, 1 MHz - limits high-frequency EMI in fast-switching flyback and buck converters. |
Pinout & Package
Package: Powermite3® SMT (190 × 300 mils footprint, 1 mm max height), molded plastic body with full metallic bottom and integral locking tab for mechanical retention and thermal transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current terminal | Connected to source/hot rail; accepts up to 50 A non-repetitive surge (IFSM). |
| Cathode | Output current terminal | Connected to load/ground; designed with 0.25" × 1.0" copper pad for optimal heat spreading. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Enhances ESD and surge immunity without external TVS; prevents localized avalanche during line transients. |
| No reverse recovery | Eliminates switching loss and ringing in high-frequency (>500 kHz) topologies; enables clean turn-off in synchronous rectifiers. |
| Full metallic bottom | Prevents solder flux entrapment during reflow; provides direct thermal interface to PCB ground plane or heatsink layer. |
| Low profile (1 mm max) | Enables stacking in ultra-thin power modules and space-constrained IoT power bricks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EYH04-M3 | 40 V, 3 A, VF = 0.52 V min @ 3 A - higher typical VF; TO-277 package (larger footprint, no metallic bottom). | Requires larger PCB area and lacks integrated thermal path; suitable where board space is unconstrained. | Select if legacy TO-277 layout exists and thermal budget permits +0.06 V VF penalty. |
| ON Semiconductor MBR340T3G | 40 V, 3 A, VF = 0.53 V typ. @ 3 A; SOD-123FL package - no locking tab, no full metallic bottom, RθJA ≈ 75°C/W. | Limited to <1.5 A continuous in same PCB layout due to inferior thermal performance. | Choose only for cost-sensitive, low-power (<1.2 W dissipation) designs with ample airflow. |
Compared with VS-3EYH04-M3 and MBR340T3G, UPS340/TR13 uniquely combines low VF, Powermite3® thermal efficiency (2.5°C/W), and automated assembly readiness-making it optimal for thermally dense, high-volume SMT power supplies where footprint and thermal headroom are constrained.

FAQ
What is the maximum junction temperature rating for UPS340/TR13?
The UPS340/TR13 has an operating temperature range of -55°C to +125°C, with storage temperature extending to +150°C. Its thermal design relies on junction-to-bottom conduction (RθJB = 2.5°C/W), so actual junction temperature depends on PCB copper mass and ambient conditions-not ambient alone. For reliable 3 A operation, maintain case temperature ≤100°C per datasheet derating curves.
Does UPS340/TR13 have a specified reverse recovery time (trr)?
No-UPS340/TR13 is a silicon Schottky barrier rectifier, and therefore exhibits no measurable reverse recovery time or stored charge. This eliminates switching losses and EMI associated with PN junction recovery, making UPS340/TR13 ideal for high-frequency (>300 kHz) topologies where trr would otherwise degrade efficiency.
Can UPS340/TR13 be used in place of a standard PN rectifier like 1N5822?
Yes, UPS340/TR13 can replace 1N5822 in most 3 A, 40 V applications-but with critical advantages: lower VF (0.46 V vs. 0.55 V), no reverse recovery, and superior thermal performance in SMT layouts. However, its leakage current (15 µA max @ 25°C) is higher than 1N5822's (~500 nA), so verify suitability in ultra-low-IQ standby circuits.
What is the recommended PCB pad layout for UPS340/TR13 to achieve rated thermal performance?
To achieve the specified 2.5°C/W junction-to-bottom thermal resistance, Microsemi recommends a cathode pad of 0.075" × 1.0" and anode pad of 0.25" × 1.0", both on 2 oz copper. The full metallic bottom must contact bare copper-no solder mask over thermal pads-and the locking tab should align with a matching cutout or solder fillet for mechanical stability.
Is UPS340/TR13 RoHS compliant and halogen-free?
Yes-UPS340/TR13 complies with RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The Powermite3® package uses lead-free matte tin plating and green molding compound. Full compliance documentation, including test reports and declarations, is available upon request from Aetrix Electronics.
