Product details
Overview
UPS140/TR13 from Diodes Incorporated is a surface-mount 1 A, 40 V Schottky rectifier in Powermite (DO-216AA) package, featuring VF = 0.45 V at 1.0 A and 25°C, thermal resistance Rθj-tab = 15°C/W, and low-profile height ≤1.1 mm - optimized for reverse battery protection and OR-ing in portable power systems including USB-powered chargers and PCMCIA cards.
For engineers reviewing the UPS140/TR13 datasheet, UPS140/TR13 pinout, UPS140/TR13 application, or UPS140/TR13 equivalent, key selection criteria include forward voltage at rated current, junction-to-tab thermal resistance, peak repetitive reverse voltage, surge current rating, and compatibility with automated SMT assembly under JEDEC-standard reflow profiles.
Technical Context
The UPS140/TR13 implements a planar Schottky barrier structure on silicon die directly bonded to an exposed cathode tab, enabling low VF and efficient heat dissipation. Its DO-216AA mechanical outline complies with JEDEC registration and supports high-density PCB layouts.
Designed for DC-DC conversion stages and input-side protection in battery-backed systems, it operates across -55°C to +125°C junction temperature range and withstands dv/dt up to 10,000 V/µs - critical for fast-switching buck converters and hot-swap circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 0.45 V at IF = 1.0 A, TJ = 25°C - enables >92% efficiency in 3.3 V–5 V output converters |
| Peak Repetitive Reverse Voltage (VRRM) | 40 V - suitable for 24 V nominal input rails with safety margin |
| Average Forward Current (IO) | 1.0 A at TC = 135°C - defines continuous conduction capability with heatsinked PCB copper |
| Junction-to-Tab Thermal Resistance (Rθj-tab) | 15°C/W - allows direct thermal coupling to copper pour for passive cooling |
| Non-Repetitive Surge Current (IFSM) | 50 A (half-wave, 60 Hz) - handles inrush during hot-plug events in USB-C PD adapters |
| Package | Powermite (DO-216AA), footprint area 8.45 mm², max height 1.1 mm - fits ultra-thin mobile PCBs |
Pinout & Package
Powermite (DO-216AA) package with two terminals: anode (lead) and cathode (exposed metal tab). Cathode tab serves as primary thermal path and electrical return.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current terminal | Connected to higher-potential side (e.g., battery+, input rail); must be routed with low-inductance trace |
| Cathode (Exposed Tab) | Output current terminal & thermal interface | Electrically tied to system ground or output rail; requires minimum 100 mm² copper pour for Rθj-tab spec |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | VF = 0.45 V @ 1 A reduces conduction loss by ~35% vs. standard PN diodes in 5 V supply paths |
| Exposed cathode thermal pad | Enables 15°C/W junction-to-tab resistance - eliminates need for external heatsinks in <1 W dissipation designs |
| JEDEC DO-216AA compliance | Guarantees compatibility with standard SMT pick-and-place nozzles and reflow profiles (260°C/10 s) |
| Small footprint (8.45 mm²) | Reduces board area by 50% vs. SMA while maintaining equivalent thermal performance |
Applications
| Battery Reverse Polarity Protection | OR-ing of Dual Power Sources |
|---|---|
Use Scenario: Prevents damage when Li-ion battery is inserted backward into handheld medical monitor. IC Role / Device Role / Timing Role: Unidirectional current blocking element placed in series with battery positive line. Use Value: Low VF minimizes voltage drop across protection path, preserving >98% of battery voltage at 0.8 A load. | Use Scenario: Seamless switchover between main 12 V adapter and backup supercapacitor in industrial IoT gateway. IC Role / Device Role / Timing Role: Passive OR-ing diode enabling automatic source selection without control logic. Use Value: 50 A surge rating withstands capacitor inrush during switchover; 40 V rating covers both sources' transient overshoot. |
| USB-C Power Delivery Input Stage | PCMCIA Card Power Switching |
Use Scenario: Input rectification in compact 20 W USB-C wall charger with dual-output topology. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier replacement in flyback secondary winding. Use Value: 1.1 mm height allows integration beneath transformer; 0.75 V VF at 3 A supports burst-mode operation without thermal derating. | Use Scenario: Hot-swap isolation in legacy PCMCIA Type II card for laptop docking station. IC Role / Device Role / Timing Role: In-line power gate preventing backfeed from host to card during insertion/removal. Use Value: 10,000 V/µs dv/dt rating suppresses transients induced by connector arcing; 62 mg weight avoids mechanical stress on card edge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS14-E3/5AT (Vishay) | Same 40 V VRRM, 1 A IO, but SMA package (Rθj-a = 110°C/W vs. UPS140/TR13's 15°C/W tab path) | Lacks exposed cathode; requires larger PCB copper area to match thermal performance | Prefer UPS140/TR13 where board space is constrained and thermal management relies on tab coupling |
| SB140-TB (ON Semiconductor) | Identical electrical specs but SOD-123FL package; 1.3 mm height, 8.9 mm² footprint | Slightly taller and wider; not JEDEC DO-216AA registered | Choose UPS140/TR13 for strict DO-216AA compliance and lowest profile in high-volume SMT lines |
Compared with SS14-E3/5AT and SB140-TB, the UPS140/TR13 delivers superior thermal performance per unit area due to its patented exposed-cathode tab, enabling higher ambient operating temperatures in sealed enclosures without forced airflow.

FAQ
What is the maximum junction temperature rating for the UPS140/TR13?
The UPS140/TR13 has a maximum operating junction temperature of +125°C, as specified in its Absolute Maximum Ratings table. This limit applies under continuous conduction at rated current and must be verified using thermal modeling that accounts for PCB copper area, ambient temperature, and airflow. The UPS140/TR13 achieves this rating via its low Rθj-tab of 15°C/W when mounted to adequate cathode-side copper.
Does the UPS140/TR13 support lead-free reflow soldering?
Yes, the UPS140/TR13 is qualified for lead-free reflow soldering per J-STD-020, with a maximum lead and mounting surface temperature of 260°C for 10 seconds. Its epoxy case meets UL94 V-0 flammability rating at 1/8″ thickness, and the device marking "S40" remains legible post-reflow. The UPS140/TR13's Powermite package ensures reliable wetting and coplanarity during automated placement.
How does the UPS140/TR13 compare to standard SMA-packaged Schottky diodes in thermal performance?
The UPS140/TR13 achieves Rθj-tab = 15°C/W through its exposed cathode tab, matching the thermal performance of larger SMA packages while occupying 50% less board area. Standard SMA Schottky diodes like SS14 rely on junction-to-ambient paths (Rθj-a ≈ 110°C/W), requiring extensive copper pours. The UPS140/TR13's direct thermal path makes it preferable where PCB real estate is limited and thermal budget is tight.
Can the UPS140/TR13 be used in reverse-battery protection for 3.7 V Li-ion systems?
Yes, the UPS140/TR13 is commonly deployed for reverse-battery protection in 3.7 V Li-ion systems, such as Bluetooth headsets and wearables. With VF = 0.36 V at 0.1 A and 0.45 V at 1.0 A, it introduces minimal voltage drop while blocking reverse current up to 40 V. Its -55°C to +125°C operating range accommodates wide environmental conditions, and the UPS140/TR13's low leakage (IR = 0.4 mA at 40 V) prevents standby drain.
What is the meaning of "Powermite" in the UPS140/TR13 datasheet?
"Powermite" is Diodes Incorporated's proprietary trademarked name for its DO-216AA-compliant surface-mount package, characterized by ultra-low profile (≤1.1 mm), small footprint (8.45 mm²), and integrated exposed cathode thermal tab. It is not a generic term - the UPS140/TR13 is the only Diodes part designated as Powermite in the 1 A / 40 V class, distinguishing it from SOD-123 or SMA alternatives.
