Product details
Overview
SBLB25L30CT-E3/45 from Vishay General Semiconductor is a dual common-cathode Schottky rectifier in D2PAK (TO-263AB) package, rated for 30 V reverse voltage, 2 × 12.5 A average forward current per diode, and 0.39 V forward voltage at 12.5 A and 125 °C - optimized for high-efficiency DC/DC converters and OR-ing applications in power-dense industrial and telecom systems.
For engineers reviewing the SBLB25L30CT-E3/45 datasheet, SBLB25L30CT-E3/45 pinout, SBLB25L30CT-E3/45 application, or SBLB25L30CT-E3/45 equivalent, key selection criteria include low VF stability across temperature, 180 A surge capability, thermal resistance of 1.5 °C/W per diode, AEC-Q101 qualification eligibility, and D2PAK mounting compatibility with heatsink-integrated PCB layouts.
Technical Context
This dual Schottky rectifier integrates two independent anodes sharing a common cathode terminal, enabling synchronous OR-ing or dual-path freewheeling in compact 12 V/5 V intermediate bus architectures. Its low 0.39 V VF at 125 °C directly reduces conduction loss in high-current, thermally constrained designs.
The device operates up to 150 °C junction temperature with 1.5 °C/W typical RθJC per diode, supports 8.3 ms single half-sine IFSM surges to 180 A, and maintains <100 µA reverse leakage at 125 °C - critical for maintaining efficiency in high-frequency switching topologies above 300 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - blocks up to 30 V reverse voltage per diode without breakdown; suitable for 12 V and 24 V input rails with margin. |
| IF(AV) per diode | 12.5 A at TC = 95 °C - enables 25 A total device current handling with shared thermal path in D2PAK package. |
| VF @ 12.5 A, 125 °C | 0.39 V - minimizes conduction loss (≈4.9 W per diode at full load), improving system efficiency in high-current DC/DC stages. |
| IFSM | 180 A - withstands short-duration inrush and fault currents in power supply startup and transient events. |
| RθJC per diode | 1.5 °C/W - enables direct heatsink coupling via exposed cathode pad; supports >75 W dissipation with 112.5 °C ΔT at 12.5 A. |
| TJ max. | 150 °C - allows operation in sealed enclosures or high-ambient environments without derating below full current rating. |
Pinout & Package
D2PAK (TO-263AB) surface-mount package with isolated heatsink tab (cathode-connected), matte tin-plated leads, RoHS-compliant, halogen-free (M3 suffix), and qualified per JESD 201 Class 1A whisker test.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Input terminal for first diode path; electrically isolated from Pin 2 and heatsink tab. |
| Pin 2 | Anode 2 | Input terminal for second diode path; independent of Pin 1 but shares cathode (tab). |
| Heatsink Tab (Pin 3 / K) | Common Cathode | Primary thermal and electrical return node; must be soldered to large copper pour or heatsink for RθJC = 1.5 °C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| Very low forward voltage drop | 0.39 V at 12.5 A and 125 °C - reduces power loss by ≥25 % vs. standard Schottkys with VF > 0.5 V under same conditions. |
| High forward surge capability | 180 A IFSM (8.3 ms) - sustains repeated inrush events in hot-swap and redundant power modules without degradation. |
| Common cathode dual configuration | Single-package dual-diode topology - eliminates interconnect inductance between cathodes, improving OR-ing transient response and layout compactness. |
| Thermally optimized D2PAK package | 1.5 °C/W RθJC per diode with exposed cathode tab - delivers 2× thermal performance vs. TO-220AB variants (RθJC = 4.0 °C/W). |
Applications
| Server OR-ing Circuit | Industrial DC/DC Converter |

This rating is confirmed in the Vishay datasheet Document Number 88731, Section "Maximum Ratings".
Is the SBLB25L30CT-E3/45 RoHS-compliant and halogen-free?
Yes, the SBLB25L30CT-E3/45 carries the M3 suffix, indicating full RoHS compliance and halogen-free construction per Vishay's material specifications. It also meets JESD 201 Class 1A whisker testing requirements, ensuring long-term solder joint reliability in thermal cycling applications.
What is the thermal resistance from junction to case for each diode in the SBLB25L30CT-E3/45?
The SBLB25L30CT-E3/45 has a typical thermal resistance of 1.5 °C/W per diode from junction to case (RθJC), measured with the cathode tab properly soldered to a thermal pad. This value is significantly lower than the TO-220AB (4.0 °C/W) and ITO-220AB (4.0 °C/W) variants in the same family.
Does the SBLB25L30CT-E3/45 support AEC-Q101 qualification?
The base SBLB25L30CT-E3/45 is not AEC-Q101 qualified; however, the functionally identical SBLB25L30CTHM3/I variant is AEC-Q101 qualified for automotive applications. Both share the same D2PAK package, electrical specs, and thermal performance - only the qualification and packaging differ.
What is the forward voltage drop of the SBLB25L30CT-E3/45 at 12.5 A and 25 °C?
At 12.5 A and 25 °C, the SBLB25L30CT-E3/45 exhibits a maximum instantaneous forward voltage of 0.49 V per diode, as specified in the "Electrical Characteristics" table of Vishay Document Number 88731. This value increases to 0.39 V at 125 °C due to Schottky barrier physics.
