Product details
Overview
UB10CCT-E3/8W from Vishay General Semiconductor is a dual common cathode ultrafast rectifier in TO-263AB package, rated for 100 V repetitive peak reverse voltage, 5.0 A average forward current per diode, and 25 ns maximum reverse recovery time. It delivers low forward voltage (0.89 V at 5.0 A, 150 °C), high surge capability (55 A), and soft recovery for high-efficiency DC/DC converters and switching power supplies.
For engineers reviewing the UB10CCT-E3/8W datasheet, UB10CCT-E3/8W pinout, UB10CCT-E3/8W application, or UB10CCT-E3/8W equivalent, this page provides verified electrical parameters, thermal resistance (5.3 °C/W junction-to-case), TO-263AB mechanical layout, and validated alternatives for low-voltage, high-frequency rectification and freewheeling roles.
Technical Context
The UB10CCT-E3/8W integrates two independent ultrafast silicon diodes sharing a common cathode terminal, enabling compact dual-path rectification without external interconnection. Its oxide planar chip junction and soft recovery characteristics minimize EMI and switching losses in high-frequency topologies.
Designed for surface-mount assembly on thermally enhanced PCBs, it supports peak junction temperatures up to 150 °C and meets J-STD-020 MSL Level 1 (245 °C reflow). Thermal resistance is specified at 5.3 °C/W (junction-to-case) and 25 °C/W (junction-to-ambient), confirming suitability for heatsinked or board-level thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating range in 12–48 V DC/DC and SMPS outputs. |
| IF(AV) per diode | 5.0 A - Continuous average forward current per diode at TC = 25 °C; derates linearly above 25 °C case temperature. |
| trr | 25 ns - Maximum reverse recovery time under IF = 1.0 A, dI/dt = 100 A/μs; enables stable operation up to ~5 MHz switching frequencies. |
| VF | 0.89 V at 5.0 A, 150 °C - Low conduction loss ensures >95% efficiency in high-current, low-voltage output stages. |
| IFSM | 55 A - Non-repetitive peak forward surge current (8.3 ms half-sine); withstands inrush and transient overloads in power-up sequences. |
| RθJC | 5.3 °C/W - Junction-to-case thermal resistance; allows direct heatsink mounting or copper pour design for thermal dissipation. |

Applications
| Switch-Mode Power Supply Output Rectification | Active Clamp Forward Converter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in 12 V/5 A and 24 V/3 A isolated DC/DC modules operating at 300–500 kHz. IC Role / Device Role / Timing Role: Dual-path ultrafast rectifier providing low-loss, low-noise output current commutation synchronized with primary-side MOSFET switching. Use Value: 0.89 V forward drop at full load reduces conduction loss by ≥15% vs. standard fast recovery diodes, directly improving power density and thermal margin. | Use Scenario: Freewheeling path in active clamp forward converters used in telecom power shelves and industrial PLC power supplies. IC Role / Device Role / Timing Role: Common-cathode dual diode clamps transformer reset energy and recirculates magnetizing current during dead time. Use Value: 25 ns trr and soft recovery prevent voltage spikes exceeding 120% of input rail, eliminating need for TVS clamping in most designs. |
| Polarity Protection in 24 V Automotive ECUs | Isolated Dual-Output DC/DC Converter |
Use Scenario: Reverse-polarity protection for 24 V engine control units where space-constrained PCB layout requires minimal footprint and no external fuse coordination. IC Role / Device Role / Timing Role: Series-connected dual-anode rectifier acting as bidirectional blocking element with common cathode tied to system ground. Use Value: 55 A IFSM withstands jump-start transients; TO-263AB's robust thermal path maintains <125 °C junction rise under 10 A continuous reverse fault current. | Use Scenario: Dual independent 5 V and 3.3 V outputs from a single transformer secondary in medical sensor interface modules. IC Role / Device Role / Timing Role: Dual-anode, common-cathode rectifier delivering isolated, independently regulated outputs without cross-regulation coupling. Use Value: Matched VF and trr between diodes ensure balanced load sharing and <±2% output voltage deviation across 10–100% load range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast dual common cathode rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8L06D | 600 V VRRM, 8 A IF(AV) per diode, 35 ns trr, TO-220AC package | Higher voltage rating suits 48 V–400 V systems; larger through-hole footprint increases layout area and thermal mass. | Select when higher reverse voltage margin or legacy through-hole assembly is required; not suitable for space-constrained SMT designs. |
| ON Semi MUR1020CT | 200 V VRRM, 5 A IF(AV) per diode, 35 ns trr, TO-220AB package | Same current rating but slower recovery and through-hole mounting; lacks MSL Level 1 reflow compatibility. | Choose for cost-sensitive 200 V applications where 25 ns speed is noncritical and reflow compatibility is not required. |
Compared with STTH8L06D and MUR1020CT, the UB10CCT-E3/8W offers superior high-frequency performance (25 ns vs. ≥35 ns), surface-mount compatibility (TO-263AB), and optimized thermal resistance (5.3 °C/W) - making it the preferred choice for compact, high-efficiency 100 V DC/DC converters requiring minimal layout overhead and reliable reflow assembly.

FAQ
What is the maximum junction temperature rating for the UB10CCT-E3/8W?
The UB10CCT-E3/8W has a maximum operating junction temperature of +150 °C, as specified in its absolute maximum ratings table. This rating applies under steady-state conditions with proper thermal management - including adequate PCB copper area or heatsink attachment to the exposed cathode tab. Derating curves confirm usable operation down to –55 °C storage temperature.
Does the UB10CCT-E3/8W support lead-free reflow soldering?
Yes, the UB10CCT-E3/8W is qualified for lead-free reflow per J-STD-020 MSL Level 1, with a maximum peak reflow temperature of 245 °C. Its TO-263AB package uses matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102, ensuring reliable wetting and joint integrity during standard Pb-free SMT processes.
How does the dual common cathode configuration of the UB10CCT-E3/8W benefit PCB layout?
The dual common cathode configuration of the UB10CCT-E3/8W eliminates the need for external copper traces to join two separate cathodes, reducing parasitic inductance and layout area. Pin 1 and Pin 2 serve as independent anodes, while the exposed metal tab (K) functions as the shared cathode - enabling symmetric, low-inductance current paths ideal for interleaved or dual-output converter topologies.
What is the typical forward voltage of the UB10CCT-E3/8W at 5.0 A and 150 °C?
The typical forward voltage of the UB10CCT-E3/8W is 0.89 V at 5.0 A and 150 °C junction temperature, as confirmed in the Electrical Characteristics table. This value reflects real-world conduction loss under elevated thermal stress and supports accurate efficiency modeling for high-temperature environments such as enclosed industrial power supplies.
Is the UB10CCT-E3/8W suitable for use in automotive applications?
The UB10CCT-E3/8W is rated for operation from –55 °C to +150 °C and meets JESD201 Class 1A whisker testing, supporting under-hood and ECU-level deployment. While not AEC-Q101 qualified, its robust surge rating (55 A IFSM), soft recovery, and TO-263AB thermal performance make it suitable for non-safety-critical automotive power conversion - subject to customer validation per ISO/TS 16949 design controls.
