Product details
Overview
UPS140E3/TR13 from Microsemi (now Microchip Technology) is a surface-mount 1 A, 40 V Schottky barrier rectifier in Powermite™ (DO-216AA) package, featuring VF = 0.45 V at IF = 1.0 A, thermal resistance Rθj-tab = 15 °C/W, and low-profile height ≤1.1 mm - optimized for reverse battery protection and OR-ing in portable DC-DC converters.
For engineers reviewing the UPS140E3/TR13 datasheet, UPS140E3/TR13 pinout, UPS140E3/TR13 application, or UPS140E3/TR13 equivalent, key selection criteria include forward voltage drop at 1 A, junction-to-tab thermal resistance, peak surge current rating (50 A), operating junction temperature range (–55 to +125 °C), and DO-216AA mechanical compatibility with space-constrained PCB layouts.
Technical Context
The UPS140E3/TR13 implements a planar Schottky barrier structure on silicon die directly bonded to an exposed cathode metal tab, enabling low VF and efficient heat dissipation. Its rated 40 V blocking voltage and 1.0 A average forward current are specified at TC = 135 °C, supporting high-density power stages in battery-fed systems.
Thermal design leverages the patented Powermite™ package geometry: the cathode serves as both electrical terminal and primary thermal path (Rθj-tab = 15 °C/W), while the anode lead provides secondary conduction (Rθj-anode = 35 °C/W). Pulse testing conditions (≤250 µs, ≤2% duty cycle) define all VF and IR measurements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM / VR | 40 V - Maximum DC or repetitive peak reverse voltage before breakdown; sets safe operating limit in 3.3 V/5 V/12 V rail OR-ing and reverse polarity protection. |
| IO (TC = 135°C) | 1.0 A - Continuous average forward current capability when case temperature is held at 135 °C; defines steady-state power handling in thermally managed layouts. |
| VF @ IF = 1.0 A | 0.45 V - Forward voltage drop at rated current; directly determines conduction loss (0.45 W) and efficiency in low-voltage DC-DC outputs. |
| IFSM | 50 A - Non-repetitive surge current rating (half-wave, 60 Hz); supports robustness against inrush or fault transients in charger input stages. |
| Rθj-tab | 15 °C/W - Junction-to-cathode-tab thermal resistance; enables direct heatsinking via PCB copper pour under exposed cathode pad. |
| TJ Range | –55 to +125 °C - Operating junction temperature limits; validates suitability for industrial and extended-temperature portable environments. |
Pinout & Package
UPS140E3/TR13 uses the Powermite™ (JEDEC DO-216AA) surface-mount package: molded epoxy case with exposed cathode metal tab on bottom, anode lead on one side, and device marking "S40" on top surface. Total footprint area is 8.45 mm²; maximum height is 1.1 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead) | Forward current entry point | Soldered to input node (e.g., battery+, supply rail); carries full load current and contributes to thermal path via leadframe. |
| Cathode (Exposed Tab) | Forward current exit / Heat sink interface | Electrically connected to output/load; must be soldered to large PCB copper area for thermal management (Rθj-tab = 15 °C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at 1 A | 0.45 V ensures <0.45 W conduction loss at full rated current, improving efficiency and reducing thermal stress in compact battery-powered designs. |
| Exposed cathode tab | Direct die-to-PCB thermal path achieves Rθj-tab = 15 °C/W - matching SMA thermal performance in 50% smaller footprint. |
| DO-216AA package | JEDEC-standardized footprint enables automated placement and reflow compatibility; 1.1 mm max height supports ultra-thin end equipment. |
| 12 mm tape & reel | Supplied in 12,000-unit reels compatible with high-speed pick-and-place machines; reduces line changeover time in volume production. |

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 = 75 °C/W); VF = 0.5 V @ 1 A. | Larger footprint (28.4 mm² vs. 8.45 mm²); less suitable for ultra-thin devices. | Choose when existing SMA land pattern is fixed and thermal margin allows higher Rθj. |
| SB140-TB (ON Semiconductor) | DO-214AA (SMA) package; VF = 0.475 V @ 1 A; Rθj-a = 70 °C/W; IFSM = 30 A. | Lower surge rating and inferior thermal path limit use in high-transient environments. | Prefer where cost sensitivity outweighs thermal or surge performance requirements. |
Compared with SS14-E3/5AT and SB140-TB, the UPS140E3/TR13 delivers superior thermal performance per unit area (15 °C/W vs. ≥70 °C/W) and 67% smaller footprint - critical for modern portable electronics where board space and junction temperature control are limiting factors.

FAQ
What is the maximum continuous forward current rating for UPS140E3/TR13?
The UPS140E3/TR13 is rated for 1.0 A average rectified forward current at case temperature TC = 135 °C. This rating assumes proper PCB thermal management - specifically, soldering the exposed cathode tab to ≥100 mm² of 2-oz copper - to maintain junction temperature within –55 to +125 °C limits. Derating applies above TC = 135 °C.
Does UPS140E3/TR13 have a documented pin-compatible replacement?
No documented pin-compatible (P2P) replacement exists for UPS140E3/TR13 due to its proprietary Powermite™ (DO-216AA) package with integrated exposed cathode tab. Alternative Schottky rectifiers like SS14-E3/5AT use SMA (DO-214AC) and require PCB layout revision. Always verify land pattern dimensions and thermal pad requirements before substitution.
What is the forward voltage drop of UPS140E3/TR13 at 1.0 A and 25°C?
The UPS140E3/TR13 exhibits a maximum instantaneous forward voltage of 0.45 V at IF = 1.0 A and TJ = 25 °C, measured under pulse conditions (pulse width ≤250 µs, duty cycle ≤2%). At elevated temperatures or DC conditions, VF may rise slightly - e.g., ~0.48 V at TJ = 125 °C - but remains below 0.5 V across full operating range.
Can UPS140E3/TR13 be used for reverse battery protection in a 3.7 V Li-ion system?
Yes - UPS140E3/TR13 is routinely deployed for reverse battery protection in 3.7 V Li-ion systems. With VR = 40 V and VF ≈ 0.45 V at 1 A, it blocks reverse current while introducing minimal forward drop. Its –55 to +125 °C TJ range and 50 A IFSM ensure reliability during hot-swap events and cold-weather operation in portable devices.
What is the thermal resistance from junction to ambient for UPS140E3/TR13?
The UPS140E3/TR13 has a junction-to-ambient thermal resistance (Rθja) of 248 °C/W under standard JEDEC test conditions (single-layer 1 in² copper pad). However, this value drops significantly with enhanced PCB cooling: Rθj-tab = 15 °C/W when the exposed cathode tab is soldered to ≥100 mm² of 2-oz internal or external copper, making Rθja highly layout-dependent.
