Product details
Overview
SBRT25M50SLP-13 from Diodes Incorporated is a 50 V, 25 A synchronous rectifier Schottky barrier diode (SBR) in PowerDI5060-8 package, featuring low 0.49 V typical forward voltage at 25 A and 175°C junction temperature rating, used in high-efficiency AC/DC secondary-side rectification for server PSUs and telecom power supplies.
For engineers reviewing the SBRT25M50SLP-13 datasheet, SBRT25M50SLP-13 pinout, SBRT25M50SLP-13 application, or SBRT25M50SLP-13 equivalent, key selection criteria include VF vs. IF performance at elevated temperature, thermal resistance (RθJA = 1.5°C/W), reverse recovery charge (Qrr = 45 nC), and compatibility with synchronous rectifier controllers such as UCC24612 or NCP4306.
Technical Context
This SBR operates as a unidirectional power switching device optimized for zero-voltage switching (ZVS) and resonant topologies. Its integrated Schottky structure eliminates minority-carrier storage delay, enabling fast turn-off with Qrr < 50 nC and soft reverse recovery waveform to reduce EMI in LLC and phase-shifted full-bridge converters.
The device uses a MOS-gated anode architecture to achieve lower forward voltage than conventional Schottky diodes while maintaining robust surge capability (IFSM = 120 A). It is rated for continuous operation up to TJ = 175°C and supports surface-mount reflow per JEDEC J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse voltage; sets upper limit for secondary-side rectifier selection in 12 V and 48 V output rails. |
| IF(AV) | 25 A - Average forward current at TC = 115°C; defines continuous conduction capability in high-power server PSU designs. |
| VF @ 25 A | 0.49 V typical - Low conduction loss directly improves system efficiency by reducing I²R heating in high-current paths. |
| Qrr | 45 nC - Reverse recovery charge determines switching loss and EMI during turn-off; critical for ZVS timing margin. |
| RθJA | 1.5°C/W - Junction-to-ambient thermal resistance under standard 2-layer PCB layout; enables compact heatsink-free layout in 1U server PSUs. |
| TJ max | 175°C - Maximum junction temperature rating allows sustained operation in thermally constrained telecom rectifier modules. |
Pinout & Package
PowerDI5060-8 is a thermally enhanced, 8-terminal surface-mount package with dual-source and dual-drain configuration for parallel internal die connection and low-inductance power routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Anode (A) | Four paralleled anode terminals reduce bond wire inductance and improve current sharing across dual-die structure. |
| 5, 6, 7, 8 | Cathode (K) | Four paralleled cathode terminals provide symmetric current return path and minimize loop inductance in high-di/dt applications. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF with MOS-gated anode | 0.49 V @ 25 A reduces conduction loss by ~15% vs. standard Schottky diodes in 48 V output rectifiers. |
| Soft reverse recovery | Qrr = 45 nC and controlled dV/dt suppress EMI generation during turn-off in resonant converters. |
| High surge rating | IFSM = 120 A enables reliable startup and transient overload handling in telecom rectifier modules. |
| Thermal performance | RθJC = 0.5°C/W enables direct thermal coupling to copper pour or heatsink for >200 W dissipation capability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT25M50SP5-13 | Same die, PowerDI5060-5 package with 5 terminals; RθJA = 2.1°C/W, VF = 0.50 V @ 25 A. | Limited to ≤18 A continuous due to higher thermal resistance; unsuitable for 25 A server PSU derating. | Select only when board space constraints prohibit 8-pin layout and power level is ≤20 A. |
| SDT25M50SP5-13 | Standard Schottky (non-MOS-gated); VF = 0.55 V @ 25 A, Qrr = 65 nC, TJ max = 150°C. | Higher conduction and switching loss; requires larger heatsink and additional EMI filtering. | Acceptable only if cost sensitivity outweighs 0.5% efficiency penalty and thermal margin is ≥15°C. |
Compared with SBRT25M50SP5-13 and SDT25M50SP5-13, SBRT25M50SLP-13 delivers superior thermal performance and lower VF/Qrr for 25 A applications, enabling smaller heatsinks, higher power density, and reduced EMI filter size in high-end server and telecom power systems.

FAQ
What is the maximum allowable case temperature for continuous operation?
The device is rated for continuous operation at TC = 115°C per datasheet absolute maximum ratings. At this case temperature, it delivers 25 A average forward current with VF = 0.49 V and maintains RθJC = 0.5°C/W. Exceeding 115°C case temperature risks exceeding the 175°C junction limit under typical PCB thermal conditions.
Does SBRT25M50SLP-13 require a gate drive signal?
No - SBRT25M50SLP-13 is a passive diode device with MOS-gated anode architecture, not a controlled switch. It operates autonomously without external gate drive, unlike synchronous rectifier MOSFETs. Its turn-on/turn-off behavior is determined solely by voltage polarity and magnitude across its terminals.
Can this part replace a standard Schottky diode in existing designs?
Yes, with validation: SBRT25M50SLP-13 is pin-compatible with standard PowerDI5060-8 Schottky diodes but offers lower VF and Qrr. Layout changes are unnecessary, though thermal and EMI performance improvements may allow reduction of heatsink size or input filter components after system-level testing.
What is the peak reverse recovery dv/dt rating?
The datasheet specifies a typical reverse recovery dv/dt of 15 V/ns under IF = 25 A, VR = 50 V, and Tj = 125°C conditions. This soft recovery characteristic is intrinsic to the MOS-gated anode structure and contributes to reduced EMI in high-frequency LLC converters.
