Product details
Overview
SBL860 from Diodes Incorporated is an 8.0A, 60V Schottky barrier rectifier in TO-220AC package, designed for low-voltage, high-frequency inverters, freewheeling, and polarity protection circuits. It features 0.70V forward voltage at 8A/25°C, 200A non-repetitive surge capability, and 6.9°C/W junction-to-case thermal resistance.
For engineers reviewing the SBL860 datasheet, SBL860 pinout, SBL860 application, or SBL860 equivalent, key selection criteria include its 60V blocking rating, low VF for efficiency-critical DC-DC stages, TO-220AC thermal performance on heatsinks, and RoHS-compliant bright tin terminals.
Technical Context
This discrete Schottky diode uses a guard ring structure to enhance transient robustness and suppress leakage under reverse bias. Its low forward voltage drop and high surge current rating make it suitable for high-efficiency switching power supplies operating below 60V DC bus.
The device operates across –65°C to +150°C with junction-to-case thermal resistance optimized for direct heatsink mounting. Junction capacitance of 700pF at 4V reverse bias supports moderate-frequency switching up to several hundred kHz without excessive capacitive losses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse voltage; defines safe DC blocking limit in polarity protection or freewheeling paths |
| IF(AV) | 8 A @ TC = 95°C - Continuous forward current rating when case temperature is maintained at 95°C via heatsink |
| VFM | 0.70 V @ IF = 8A, TC = 25°C - Forward voltage drop directly impacts conduction loss and thermal design in high-current paths |
| IFSM | 200 A (8.3ms half-sine) - Peak surge withstand capability for inrush or fault conditions in motor drives or SMPS |
| RθJC | 6.9 °C/W - Thermal resistance from junction to case; determines required heatsink size for given power dissipation |
| IRM | 50 mA @ TC = 100°C - Reverse leakage at elevated temperature; affects standby loss in battery-powered polarity guards |
| Cj | 700 pF @ VR = 4V, 1MHz - Junction capacitance influences switching speed and EMI in high-frequency rectification |
Pinout & Package
Package: TO-220AC - Molded plastic case (UL 94V-0), 2.3g weight, lead-free bright tin terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to input/high-side node in freewheeling or polarity protection; carries full load current |
| Pin 2 | Cathode | Connected to output/low-side node; common connection point for heat transfer to heatsink tab |
| Case (Tab) | Anode | Electrically tied to Pin 1; must be isolated from chassis unless circuit topology permits common-anode mounting |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Enhances transient voltage immunity and stabilizes reverse leakage under fast dv/dt conditions |
| Low VF Schottky die | Reduces conduction loss by ~30% vs. comparable silicon rectifiers, improving efficiency in 12–48V systems |
| TO-220AC thermal interface | Enables direct heatsink mounting with low thermal impedance-critical for sustained 8A operation |
| RoHS-compliant finish | Bright tin plating ensures reliable solder wetting and long-term intermetallic stability in automated assembly |
Applications
| DC-DC Converter Output Rectification | Automotive Polarity Protection |
|---|---|
Use Scenario: Secondary-side synchronous or Schottky rectification in 12V/24V/48V isolated DC-DC converters for telecom or industrial power supplies. IC Role / Device Role / Timing Role: Freewheeling diode conducting during low-side switch off-time; handles continuous 8A output current. Use Value: 0.70V VF minimizes conduction loss at full load, reducing thermal stress and enabling compact heatsink design. | Use Scenario: Reverse-polarity protection at vehicle battery input (12V/24V) for infotainment, ADAS, or body control modules. IC Role / Device Role / Timing Role: Anode-connected to battery; blocks reverse current during accidental cable reversal. Use Value: 60V VRRM exceeds automotive load-dump transients; 200A IFSM survives jump-start surges. |
| UPS Inverter Freewheeling | Industrial Motor Drive Snubbing |
Use Scenario: Freewheeling path in single-phase H-bridge inverters for offline UPS systems delivering 500–1000VA. IC Role / Device Role / Timing Role: Provides low-loss current recirculation during PWM dead-time; clamps inductive kickback. Use Value: 700pF junction capacitance limits high-frequency ringing; TO-220AC package sustains repeated 8A pulses. | Use Scenario: Snubber diode across relay coils or small BLDC motor phase windings in PLC-controlled machinery. IC Role / Device Role / Timing Role: Suppresses inductive voltage spikes during coil de-energization in 24–48V control circuits. Use Value: Guard ring improves reliability against repetitive 100V+ transients; 6.9°C/W RθJC enables ambient-rated operation. |
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 60V/8A rating, but TO-220AB package with insulated tab; RθJC = 7.0°C/W; VF = 0.69V @ 8A | Insulated tab eliminates need for isolation hardware in grounded-chassis designs | Select when electrical isolation between case and anode is required without external insulator |
| ON Semiconductor MUR860EG | Ultrafast silicon rectifier (600V/8A); VF = 1.7V @ 8A; higher switching loss; no Schottky leakage trade-off | Higher reverse voltage margin; suitable where 60V blocking is insufficient or surge energy exceeds Schottky limits | Select only if system requires >60V blocking or must tolerate >150°C junction temperatures beyond Schottky limits |
Compared with VS-8EWH06FN-M3, SBL860 offers lower thermal resistance and non-insulated mounting flexibility; versus MUR860EG, it delivers significantly lower conduction loss but trades off reverse voltage headroom and high-temperature reliability.

FAQ
Is SBL860 suitable for surface-mount assembly?
No. SBL860 uses the through-hole TO-220AC package with leads designed for axial insertion and wave or selective soldering. It lacks SMD-compatible footprint or thermal pad geometry. For SMT alternatives, consider Diodes' SB860-E3/54 (TO-263) or similar 60V/8A Schottky variants with D2PAK packaging.
What is the maximum allowable case temperature for continuous 8A operation?
The datasheet specifies IF(AV) = 8A at TC = 95°C. Exceeding this case temperature reduces safe current handling-derating begins immediately above 95°C, reaching zero at 150°C per Figure 1. Heatsink design must maintain case ≤95°C under worst-case ambient and airflow conditions.
Does SBL860 have avalanche rating or ruggedness specification?
No. As a Schottky rectifier, SBL860 is not rated for repetitive avalanche operation. Its guard ring improves transient immunity, but it lacks specified unclamped inductive switching (UIS) capability. For circuits subject to high-energy inductive turn-off, add external TVS or RC snubbers.
Why is SBL860 marked "NOT RECOMMENDED FOR NEW DESIGN"?
Diodes Incorporated issued this notice due to newer-generation Schottky rectifiers offering lower VF (e.g., 0.55V), improved high-temperature IR stability, or enhanced surge robustness. SBL860 remains fully functional and supported for existing designs, but new projects should evaluate successors like the SB860H or APx60 series.
