Product details
Overview
SBRT5A50SA-13 from Diodes Incorporated is a 5A, 50V trench super barrier rectifier (SBR®) in SMA package, featuring ultra-low forward voltage (0.53 V max at 5 A, 25°C), low reverse leakage (0.15 mA max at 50 V, 25°C), and high-temperature stability up to +150°C - deployed as a boost diode in DC-DC converters for telecom power supplies.
For engineers reviewing the SBRT5A50SA-13 datasheet, SBRT5A50SA-13 pinout, SBRT5A50SA-13 application, or SBRT5A50SA-13 equivalent, key selection criteria include forward voltage trade-offs at elevated temperature, thermal resistance (RθJA = 40°C/W), reverse leakage behavior at 125°C, and SMA package solderability per MIL-STD-202.
Technical Context
This SBR device uses patented trench-based super barrier technology to achieve lower VF than standard Schottky diodes while maintaining superior high-temperature IR stability. Its architecture suppresses minority-carrier injection and reduces surface recombination, enabling stable operation under sustained 125°C ambient conditions with only 45 µA leakage at 50 V.
The device is rated for 70 A non-repetitive surge current (8.3 ms half-sine), supports capacitive-load derating (−20% IO), and exhibits typical junction-to-case thermal resistance of 25°C/W - critical for compact board layouts where heatsinking is limited.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage; defines safe DC/AC peak voltage limit before avalanche conduction. |
| IO (AV) | 5 A - Average rectified output current on FR-4 PCB (1"×1", 2 oz Cu); usable in continuous conduction mode without forced cooling. |
| VF (max) | 0.53 V @ 5 A, 25°C - Enables <1.5 W conduction loss at full load; reduces thermal stress vs. conventional Schottky alternatives. |
| IR (max) | 0.15 mA @ 50 V, 25°C - Low leakage preserves efficiency in standby; rises to 45 µA at 125°C, limiting thermal runaway risk. |
| RθJA | 40 °C/W - Junction-to-ambient thermal resistance on standard FR-4; determines temperature rise (ΔT = Pd × RθJA) under real PCB conditions. |
| TJ Range | −55°C to +150°C - Extended operating range enables deployment in automotive under-hood and industrial motor drive environments. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with cathode band marking; UL 94V-0 rated, halogen/antimony-free "Green" compound; matte tin–annealed copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to input/source side in boost or recirculation paths; requires adequate trace width for 5 A RMS. |
| Cathode | Current exit terminal during forward conduction; marked with band | Connected to output/load or switching node; polarity must be verified before placement to avoid reverse bias failure. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF at high current | 0.46 V typ @ 5 A, 25°C - Reduces conduction loss by ≥15% vs. comparable Schottky diodes, improving system efficiency in 12 V–48 V DC-DC stages. |
| High-temperature IR stability | 45 µA @ 50 V, 125°C - Limits thermal runaway risk in enclosed enclosures or high-ambient environments like base station power modules. |
| Trench SBR® technology | Patented barrier structure - Combines low VF of Schottky with higher VRRM and better IR control than planar Schottky or fast recovery diodes. |
| RoHS & Green compliance | Lead-free, halogen-free (<900 ppm Br/Cl, <1000 ppm Sb) - Meets EU RoHS 3 and IPC-1752A material declaration requirements for industrial and telecom OEMs. |
Applications
| Boost Diode in Telecom DC-DC Converters | Blocking Diode in Solar Charge Controllers |
|---|---|
Use Scenario: Used in non-isolated boost converters supplying 48 V intermediate bus from 12 V or 24 V battery input in telecom shelf power systems. IC Role / Device Role / Timing Role: Rectifies switched inductor current into output capacitor; conducts during MOSFET off-time with minimal voltage drop. Use Value: 0.53 V VF maximizes conversion efficiency (>94% at 5 A), reducing heat sink size and enabling higher power density in 1U rack units. | Use Scenario: Prevents reverse current flow from battery to PV panel at night or low-light conditions in off-grid solar charge controllers. IC Role / Device Role / Timing Role: Unidirectional blocking element placed between panel and battery terminals; sustains 50 V reverse bias continuously. Use Value: 0.15 mA IR at 25°C and 45 µA at 125°C ensures negligible standby loss, preserving battery autonomy over extended no-sun periods. |
| Recirculating Diode in BLDC Motor Drivers | Output Rectifier in Industrial SMPS |
Use Scenario: Freewheeling path for phase-current decay during PWM dead-time in 3-phase brushless DC motor gate drivers. IC Role / Device Role / Timing Role: Provides low-loss return path for inductive kickback; conducts brief high-di/dt pulses synchronized to gate timing. Use Value: 70 A IFSM rating handles transient surges without degradation; low VF minimizes voltage overshoot and EMI generation during commutation. | Use Scenario: Secondary-side rectification in 24 V/5 A industrial switch-mode power supplies powering PLC I/O modules. IC Role / Device Role / Timing Role: Converts high-frequency transformer output to regulated DC; operates in continuous conduction mode with 5 A average load. Use Value: Stable VF across −40°C to +125°C ensures consistent output regulation without compensation; RθJC = 25°C/W allows direct mounting to metal-core PCBs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT5A50S-13 | Same die, but in SMB package (larger footprint, RθJA = 35°C/W) | Better thermal performance on open-board layouts; not suitable for space-constrained SMA footprints | Select when board layout permits larger pad area and thermal management prioritizes junction-to-ambient dissipation. |
| MBR550F-E3/45 | Standard Schottky; VF = 0.72 V max @ 5 A, IR = 0.5 mA @ 50 V, 25°C | Higher conduction loss and worse high-temp leakage; acceptable only in cost-sensitive, low-ambient applications | Choose only if BOM cost is primary constraint and thermal margin exceeds 20°C at full load. |
Compared with SBRT5A50S-13, the SBRT5A50SA-13 offers identical electrical specs in a smaller SMA footprint but trades 5°C/W higher RθJA; versus MBR550F-E3/45, it delivers 36% lower VF and 3.3× less IR at 125°C - directly enabling higher efficiency and reliability in thermally demanding deployments.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The SBRT5A50SA-13 has a specified operating junction temperature range of −55°C to +150°C. For reliable long-term operation, junction temperature must remain ≤150°C under worst-case conditions - achievable with proper PCB copper area, ambient temperature control, and derating per Figure 5's forward current curve.
Is the SMA package compatible with standard reflow profiles for lead-free assembly?
Yes - the SBRT5A50SA-13 uses matte tin–annealed copper leadframe and complies with JEDEC J-STD-020 moisture sensitivity Level 1. It supports standard Pb-free reflow profiles (peak 260°C, 10–15 sec), and solderability is validated per MIL-STD-202, Method 208.
How does its reverse leakage compare to standard Schottky diodes at elevated temperature?
At 125°C and 50 V reverse bias, SBRT5A50SA-13 exhibits only 45 µA IR - approximately 3.3× lower than typical Schottky diodes (e.g., MBR550F-E3/45 at 150 µA). This significantly reduces thermal runaway risk in high-ambient applications.
Can this diode replace a standard 5A/50V fast recovery diode in a flyback snubber circuit?
No - the SBRT5A50SA-13 is a unidirectional rectifier optimized for forward conduction, not reverse recovery. It lacks controlled reverse recovery characteristics and may exhibit excessive ringing or voltage overshoot in snubber applications requiring soft recovery.
