Product details
Overview
SDT5A60SA from Diodes Incorporated is a 5.0A, 60V Trench Schottky Barrier Rectifier in SMA package, optimized for high-efficiency switching power supplies. It delivers VF = 0.52 V at 5.0 A and 25°C, IR ≤ 0.5 mA at 60 V/25°C, and operates up to +150°C junction temperature-enabling compact, thermally robust freewheeling and output rectification in DC-DC converters.
For engineers reviewing the SDT5A60SA datasheet, SDT5A60SA pinout, SDT5A60SA application, or SDT5A60SA equivalent, key selection criteria include forward voltage drop at rated current, reverse leakage at elevated temperature, thermal resistance (RθJA = 56°C/W), soft-switching behavior, and RoHS-compliant lead-free plating on SMA terminals.
Technical Context
This Schottky rectifier uses trench-based silicon process technology to reduce forward conduction loss while maintaining low reverse leakage. Its soft, fast switching capability minimizes EMI generation during turn-off transitions in high-frequency SMPS topologies.
The device is rated for 5 A average forward current with 60 A non-repetitive surge capability (8.3 ms half-sine), and features a cathode band polarity indicator. Thermal design must account for RθJC = 27°C/W and derating above 25°C ambient per Figure 4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; defines safe operating range in DC-DC output or AC-DC bridge legs |
| IO(AV) | 5 A - Continuous average forward current at TA = 25°C; derates linearly to zero at ~125°C ambient (per Fig.4) |
| VF @ 5A/25°C | 0.52 V - Low conduction loss enabling >90% efficiency in 12V–48V output stages |
| IR @ 60V/25°C | 0.5 mA - Minimal leakage preserves light-load efficiency and reduces standby power loss |
| TJ(max) | +150°C - Enables operation in sealed or high-ambient industrial/automotive enclosures without forced cooling |
| RθJA | 56°C/W - Requires ≥0.56"×0.73" copper pad on FR-4 for full 5 A rating at 25°C ambient |
Pinout & Package
SMA (DO-214AC) surface-mount package: molded green compound, matte tin-plated leads, cathode band marking, moisture sensitivity level 1, weight ≈ 0.064 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry node | Connected to switch node (e.g., MOSFET drain) in buck/flyback freewheel path |
| Cathode | Forward current exit / reverse blocking terminal | Connected to output rail; cathode band identifies this terminal visually and on PCB silkscreen |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Reduces VF by ~15% vs. planar Schottky at 5 A, lowering I²R losses in high-current paths |
| Soft, fast switching | Minimizes reverse recovery ringing and EMI in >300 kHz DC-DC converters without snubbers |
| +150°C junction rating | Supports operation in under-hood automotive modules or enclosed industrial PSUs without thermal throttling |
| Halogen & antimony free | Meets IPC-4101D/ES-21 requirements for "Green" PCB assembly and end-of-life recycling |
Applications
| Server VRM Output Rectification | Industrial DC-DC Converter |
|---|---|
Use Scenario: 48V-to-12V buck converter supplying CPU core voltage in data center servers. IC Role / Device Role / Timing Role: Freewheeling diode conducting during low-side switch off-time; handles 5 A continuous, 60 A surge. Use Value: 0.52 V VF limits conduction loss to <2.6 W, reducing heatsink size and improving power density. | Use Scenario: 24V input, 5V/3A isolated flyback supply in factory automation PLC I/O module. IC Role / Device Role / Timing Role: Secondary-side output rectifier; conducts unidirectionally during transformer reset phase. Use Value: 0.5 mA IR at 25°C ensures <1.5 mW standby loss, critical for always-on control logic. |
| Automotive Body Control Module | Telecom AC-DC Front-End |
Use Scenario: 12V battery-fed buck regulator powering infotainment display backlight drivers. IC Role / Device Role / Timing Role: Synchronous rectifier replacement in cost-sensitive BCM power rail where gate drive complexity is avoided. Use Value: +150°C TJ rating allows placement near heat-generating MCU without derating, simplifying layout. | Use Scenario: PFC-less AC-DC adapter for 5G small cell remote radio units (RRUs). IC Role / Device Role / Timing Role: Input bridge leg diode handling 50/60 Hz line frequency with 60 A surge tolerance. Use Value: 60 A IFSM withstands inrush from bulk capacitor charging, eliminating need for NTC thermistors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS5P6L-13 | Same 60 V / 5 A rating; VF = 0.55 V @ 5 A/25°C; RθJA = 60°C/W; SMA package | Higher VF increases conduction loss by ~0.15 W at full load; slightly lower thermal performance | Acceptable where 0.03 V VF penalty is tolerable and board space matches SMA footprint |
| MBR560F-TP | 60 V / 5 A; VF = 0.65 V @ 5 A/25°C; DO-214AA (SMB) package; RθJA = 45°C/W | Larger SMB package offers better thermal dissipation but occupies ~30% more PCB area | Preferred when thermal margin is constrained and layout allows SMB footprint |
Compared with SS5P6L-13 and MBR560F-TP, SDT5A60SA provides the lowest VF (0.52 V) in SMA, delivering highest efficiency in space-constrained 5 A rectification-while MBR560F-TP trades voltage drop for superior thermal resistance in larger SMB.

FAQ
What is the maximum allowable junction temperature for SDT5A60SA?
The SDT5A60SA has a specified maximum junction temperature of +150°C. This rating is validated per JEDEC test conditions and enables reliable operation in high-ambient environments such as automotive engine compartments or sealed industrial enclosures-provided thermal design meets RθJA = 56°C/W with recommended copper pad area.
Does SDT5A60SA have AEC-Q101 qualification?
No, SDT5A60SA is not AEC-Q101 qualified. It is a commercial-grade part. For automotive applications requiring AEC-Q101 compliance, Diodes offers the SDT5A60S1Q-13 variant, which shares identical electrical specs but is manufactured in IATF 16949-certified facilities and qualified per AEC-Q101 stress tests.
Can SDT5A60SA replace a standard PN junction rectifier in an existing design?
Yes-provided reverse voltage and surge requirements are met. As a Schottky device, it eliminates reverse recovery time and associated switching loss, but its higher IR at elevated temperature must be verified. Replace only if VR ≤ 60 V and peak IF ≤ 5 A; verify thermal performance due to different RθJA characteristics.
What does the "DX6" marking on the SDT5A60SA package indicate?
The "DX6" marking is Diodes Incorporated's product type code for this specific Trench Schottky rectifier. It appears adjacent to the cathode band on the SMA package top surface and is used for internal traceability and manufacturing lot identification-not as a date or revision code.
