Product details
Overview
SBG1025L-T from Diodes Incorporated is a 10A, 25V Schottky barrier rectifier in D2PAK (TO-263) package, optimized for low-voltage, high-frequency inverters and polarity protection circuits with 0.34V forward voltage at 10A/25°C and 3.0°C/W junction-to-case thermal resistance.
For engineers reviewing the SBG1025L-T datasheet, SBG1025L-T pinout, SBG1025L-T application, or SBG1025L-T equivalent, key selection criteria include forward voltage drop at rated current, surge capability (200A IFSM), thermal resistance, reverse leakage at 125°C, and D2PAK mounting compatibility with heatsink interfaces.
Technical Context
This Schottky rectifier uses guard ring die construction for transient protection and features very low forward voltage drop to minimize conduction losses in DC-DC converters and OR-ing circuits. Its 350pF junction capacitance at 4V reverse bias supports high-frequency switching up to several MHz.
The device is rated for 10A average rectified output at TC = 120°C and requires derating to 8A for capacitive loads. It operates across -65°C to +125°C junction temperature range with UL 94V-0 flammability-rated plastic encapsulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 25 V - Maximum repetitive reverse voltage before breakdown; defines safe blocking range in 24V bus protection |
| IF(AV) | 10 A @ TC = 120°C - Continuous DC current handling with heatsink; derate to 8A for capacitive loads |
| VFM | 0.34 V @ IF = 10A, TC = 25°C - Low conduction loss enabling >92% efficiency in 5–12V buck converters |
| IFSM | 200 A (8.3ms half-sine) - Withstands inrush surges in power supply startup and motor drive freewheeling |
| RJC | 3.0 °C/W - Enables direct heatsink mounting for thermal management in compact industrial power modules |
| IR @ 25°C | 150 mA - Reverse leakage at rated VR; impacts standby power in battery-backed systems |
| Cj | 350 pF @ f = 1MHz, VR = 4V - Limits high-frequency switching speed but suitable for ≤500kHz SMPS designs |
Pinout & Package
Package: D2PAK (TO-263), surface-mount, single-ended anode-cathode configuration with exposed metal tab (pin 2 & 4) serving as cathode and thermal path. Molded plastic body meets UL 94V-0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Main current entry point; connects to input/source side of rectification path |
| Pin 2 & 4 | Cathode / Thermal Tab | Common cathode terminal and primary heat dissipation surface; must be soldered to copper pour or heatsink |
| Pin 3 | Anode | Second anode connection; paralleled internally with Pin 1 for lower resistance and higher current sharing |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves ruggedness against voltage transients and ESD events without external clamping components |
| Very low forward voltage drop | 0.34V at 10A/25°C reduces power loss by ~40% vs. standard silicon rectifiers in 12V systems |
| High surge capability | 200A non-repetitive peak current supports reliable operation during motor startup and capacitor charging |
| UL 94V-0 plastic material | Meets flame-retardant safety requirements for industrial and automotive under-hood applications |

FAQ
What is the maximum junction temperature for SBG1025L-T?
The SBG1025L-T has a specified operating junction temperature range of -65°C to +125°C. This limit is defined by its silicon die process and epoxy molding compound. Exceeding +125°C risks parametric shift and accelerated degradation, especially under sustained 10A load without adequate heatsinking.
Can SBG1025L-T replace SBG1030L-T in a 24V system?
No - SBG1025L-T has 25V VRRM, while SBG1030L-T is rated for 30V. In a 24V system with potential transients (e.g., ISO 7637-2 pulse 5a), the 25V rating provides insufficient margin. Diodes' datasheet specifies SBG1030L-T for 24V nominal applications requiring ≥20% headroom above nominal rail.
Is the D2PAK thermal tab electrically isolated?
No - the exposed metal tab (pins 2 & 4) is electrically connected to the cathode. It must be mounted to a grounded or cathode-potential heatsink. Insulating pads or shoulder washers are required if mounting to a non-cathode-referenced metal surface to avoid short circuits.
How does forward voltage vary with temperature?
VFM decreases with rising junction temperature: typical values are 0.34V at 25°C, 0.45V at 125°C (at 10A). This negative temperature coefficient improves current sharing in parallel configurations but requires thermal design to maintain stable voltage regulation in precision feedback paths.
