Product details
Overview
SD860-T from Diodes Incorporated is a 60 V, 8.0 A Schottky barrier rectifier in DO-201AD package, featuring 0.7 V max forward voltage at 8 A, 175 A non-repetitive surge current, and guard ring for transient protection-used in high-efficiency AC/DC secondary-side rectification for industrial power supplies.
For engineers reviewing the SD860-T datasheet, SD860-T pinout, SD860-T application, or SD860-T equivalent, key selection criteria include reverse voltage rating (60 V), thermal resistance (30 °C/W junction-to-lead), leakage current (≤1.0 mA at 25°C), surge capability (175 A), and RoHS-compliant lead finish.
Technical Context
This device operates as a unidirectional power rectifier with metal–semiconductor junction architecture, optimized for low-loss DC output stages. Its guard ring structure enhances ruggedness against voltage transients, while the DO-201AD package enables vertical PCB mounting with 9.5 mm lead length for effective thermal conduction.
Electrical behavior is characterized by soft reverse recovery, negligible minority-carrier storage, and junction capacitance of 550 pF at 4 V reverse bias. Performance remains stable across –65°C to +150°C operating temperature range, with derating required above +25°C ambient per Figure 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for circuit blocking capability. |
| IO (AV) | 8 A - Average rectified current at TA = +25°C; defines continuous DC output capacity under standard thermal conditions. |
| VF (max) | 0.7 V @ 8 A - Forward voltage drop ceiling; directly determines conduction loss (5.6 W max at full load). |
| IFSM | 175 A @ 8.3 ms - Non-repetitive surge rating; supports inrush current handling during power-up or fault events. |
| IR (max) | 1.0 mA @ VRRM, +25°C - Reverse leakage ceiling; impacts standby power loss and thermal runaway risk in parallel configurations. |
| RθJL | 30 °C/W - Junction-to-lead thermal resistance; enables direct heatsinking via PCB copper or chassis contact using leads. |
| CJ | 550 pF @ 4 V, 1 MHz - Junction capacitance value; influences high-frequency switching noise and EMI filter design. |
Pinout & Package
DO-201AD package: axial-leaded, molded plastic case (UL 94V-0), cathode band marking polarity, 1.1 g mass, lead finish - bright tin, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to transformer secondary or switching node; must withstand peak forward surge and thermal stress. |
| Cathode | Current exit point during forward conduction | Connected to output rail; serves as primary thermal path to PCB; marked by band for orientation. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Enhances transient voltage immunity and prevents edge breakdown during fast-rising dv/dt events. |
| Low VF (0.55 V typ) | Reduces conduction loss by ~30% vs. comparable 60 V Si diodes, improving system efficiency in 12–24 V output supplies. |
| High IFSM (175 A) | Supports >20× rated current surge without failure-critical for capacitor-input filter designs with high inrush. |
| RoHS-compliant finish | Bright tin plating ensures reliable solder wetting and long-term intermetallic stability in lead-free reflow profiles. |
| DO-201AD mechanical robustness | UL 94V-0 housing and 9.5 mm lead length enable secure mechanical anchoring and repeatable thermal performance on production PCBs. |
Applications
| Server Power Supply Rectification | Industrial Motor Drive DC Link |
|---|---|
Use Scenario: Secondary-side rectification in 12 V/24 V output stages of 80 PLUS Titanium-certified server PSUs. IC Role / Device Role / Timing Role: Primary power conversion element converting transformer AC to regulated DC; no timing function. Use Value: 0.7 V VF reduces conduction loss by 1.6 W per device vs. legacy 60 V Schottky alternatives, lowering thermal load on heatsinks. | Use Scenario: Freewheeling and bus rectification in 3-phase inverter front-ends driving 0.5–5 kW AC induction motors. IC Role / Device Role / Timing Role: Unidirectional current path for regenerative braking energy and DC link smoothing; no control or timing role. Use Value: 175 A IFSM withstands motor stall surges without degradation, extending service life in harsh factory environments. |
| Solar Microinverter DC Output Stage | Telecom Rectifier Module |
Use Scenario: Output rectification in single-phase microinverters converting PV panel DC to grid-synchronized AC. IC Role / Device Role / Timing Role: High-frequency rectifier in synchronous or passive clamp topologies; operates at 20–100 kHz switching frequencies. Use Value: 550 pF junction capacitance minimizes switching losses and EMI generation when paired with GaN FETs in high-frequency designs. | Use Scenario: -48 V DC distribution rectification in carrier-grade telecom shelf power systems with N+1 redundancy. IC Role / Device Role / Timing Role: Redundant output diode in OR-ing configuration; blocks reverse current during module hot-swap or failure. Use Value: ≤1.0 mA IR at +25°C ensures minimal standby current leakage across paralleled modules, preserving system efficiency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-8EWH06FN-M3 | Same 60 V VRRM, 8 A IO, but TO-220AC package (RθJL = 10 °C/W); VF = 0.67 V typ. | Requires heatsink mounting; unsuitable for axial-leaded DO-201AD footprint replacement. | Select when board space allows TO-220 and thermal budget demands lower RθJL. |
| ON Semiconductor SB860-E3/54 | Identical DO-201AD package and 60 V/8 A rating; VF = 0.72 V max; IR = 2.0 mA max at +25°C. | Higher leakage may impact parallel operation in telecom OR-ing; same mechanical fit. | Acceptable drop-in where leakage margin >1 mA is available and thermal design matches SD860-T. |
Compared with VS-8EWH06FN-M3 and SB860-E3/54, the SD860-T offers superior leakage control (1.0 mA max) and proven guard ring ruggedness in axial-leaded form factor-making it preferred for space-constrained, high-reliability industrial rectification where thermal path relies on lead conduction rather than external heatsink.

FAQ
What is the maximum allowable junction temperature for SD860-T?
The SD860-T has an absolute maximum junction temperature of +150°C. Operation above this limit risks permanent degradation of the Schottky junction. Derating curves in Figure 1 specify that average current must be reduced linearly beyond +25°C ambient, reaching 0 A at +125°C lead temperature.
Can SD860-T be used in parallel configurations?
Yes, but only with matched forward voltage characteristics and symmetrical PCB layout. Due to negative temperature coefficient of VF, current sharing requires ballasting resistors or active balancing. Leakage current mismatch (≤1.0 mA max) also affects idle-state imbalance in OR-ing applications.
Is SD860-T suitable for high-frequency switching above 100 kHz?
Yes-its majority-carrier conduction eliminates reverse recovery charge, enabling clean turn-off at frequencies up to several hundred kHz. However, junction capacitance (550 pF) becomes significant above 500 kHz; layout parasitics and snubber design must be optimized to manage ringing and EMI.
Does SD860-T meet automotive AEC-Q101 requirements?
No-SD860-T is not AEC-Q101 qualified. It is rated for industrial temperature range (–65°C to +150°C) and RoHS compliance, but lacks the stress testing, failure analysis, and traceability documentation required for automotive use. Diodes' APx series is designated for AEC-Q101 applications.
