Product details
Overview
SB360-B from Diodes Incorporated is a 3.0A, 60V Schottky barrier rectifier in DO-201AD package, featuring 0.74V forward voltage at 3.0A, 80A non-repetitive surge capability, and guard ring die construction for transient protection. It serves as a low-loss freewheeling diode in DC-DC converters and polarity protection element in 12V/24V automotive power rails.
For engineers reviewing the SB360-B datasheet, SB360-B pinout, SB360-B application, or SB360-B equivalent, key selection criteria include its 60V VRRM rating, 0.74V VFM at rated current, thermal resistance of 30°C/W (junction-to-ambient), DO-201AD mechanical outline, and RoHS-compliant tin-plated terminals.
Technical Context
The SB360-B employs a planar Schottky junction with guard ring passivation to suppress edge breakdown and improve surge robustness. Its low forward voltage drop stems from optimized metal-semiconductor contact and low-resistance epitaxial layer design, enabling high efficiency in high-frequency switching applications up to 1 MHz.
Thermal performance is defined by two distinct paths: RθJA = 30°C/W (on FR-4 PCB with 9.5mm lead distance) and RθJL = 10°C/W (junction-to-lead, vertical mount with 12.7mm lead length and 63.5mm² copper pad), supporting reliable operation from –65°C to +125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse voltage before avalanche conduction begins; sets upper limit for blocking in 48V nominal systems. |
| IF(AV) | 3.0 A - Average forward current under specified thermal conditions; defines continuous DC output capability in rectifier circuits. |
| VFM @ 3.0A | 0.74 V - Forward voltage drop at rated DC current; determines conduction loss (2.22W at 3A) and thermal load in power path. |
| IFSM | 80 A - Non-repetitive peak surge current (8.3ms half-sine); enables survival during inrush or fault transients in SMPS inputs. |
| IRM @ 25°C | 0.5 mA - Peak reverse leakage at rated VRRM and room temperature; impacts standby power in battery-backed systems. |
| TJ Range | –65°C to +125°C - Operating junction temperature range; qualifies for under-hood automotive and industrial ambient environments. |
| RθJA | 30 °C/W - Junction-to-ambient thermal resistance on standard PCB layout; used to calculate temperature rise (ΔT = Pd × RθJA). |
Pinout & Package
DO-201AD package: axial-leaded, molded plastic case (UL 94V-0), cathode band marking, tin-plated terminals, 1.1g mass. Leads are electrically symmetric; device operates as a two-terminal unidirectional rectifier.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to lower-potential side (e.g., switch node in buck converter or negative rail in polarity protection). |
| Cathode | Current exit point during forward conduction; marked with band | Connected to higher-potential side (e.g., output capacitor positive terminal or system VBUS). |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge leakage and improves transient voltage withstand beyond rated VRRM, reducing field-induced failure risk. |
| Low forward voltage (0.74V @ 3A) | Reduces conduction loss by ~35% versus comparable 60V silicon rectifiers, lowering thermal stress in compact layouts. |
| 80A surge rating (8.3ms) | Withstands cold-start inrush in 24V industrial supplies without derating or parallel devices. |
| RoHS-compliant tin finish | Enables lead-free reflow assembly per JEDEC J-STD-020 Level 1 moisture sensitivity, eliminating post-process cleaning. |
Applications
| DC-DC Converter Freewheeling | Automotive Polarity Protection |
|---|---|
Use Scenario: Used as the catch diode in non-synchronous buck converters powering FPGA I/O banks or microcontroller cores. IC Role / Device Role / Timing Role: Provides low-loss return path for inductor current during high-side switch off-time; conducts continuously at switching frequency. Use Value: 0.74V VFM minimizes power dissipation (≤2.2W at 3A), allowing use without heatsink in space-constrained 12V→3.3V/5V modules. | Use Scenario: Placed in series with battery input to prevent damage from reverse battery connection in telematics control units. IC Role / Device Role / Timing Role: Acts as series-blocking diode; conducts only when battery polarity is correct, blocking reverse current entirely. Use Value: 60V VRRM exceeds 36V jump-start transients; 80A IFSM survives momentary short-circuit during misconnection. |
| High-Frequency Inverter Output | Industrial Power Supply OR-ing |
Use Scenario: Rectifies high-frequency AC output (20–100 kHz) from resonant LLC inverters in LED drivers and induction heating controls. IC Role / Device Role / Timing Role: Serves as output synchronous rectifier replacement; conducts during positive half-cycle with minimal recovery loss. Use Value: Schottky zero-recovery eliminates reverse recovery charge (Qrr ≈ 0), preventing shoot-through and EMI in fast-switching topologies. | Use Scenario: Implements diode-OR function between redundant 24V DC power supplies feeding PLC backplanes. IC Role / Device Role / Timing Role: Isolates supply domains while enabling seamless switchover; conducts only from higher-voltage source. Use Value: Low VFM ensures minimal voltage drop (<0.75V) across each diode, preserving regulation margin and reducing heat buildup in parallel configurations. |
Equivalent & Alternatives

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EY60-M3/54 | Same 60V VRRM, 3A IF(AV), but TO-277 package (surface-mount); VFM = 0.72V @ 3A. | Requires SMT reflow process and PCB land pattern redesign; lacks axial leads for through-hole prototyping. | Select for automated production where board space and thermal pad access are prioritized over manual assembly flexibility. |
| ON Semiconductor SB360-E3/54 | Identical electrical specs and DO-201AD package; same 0.74V VFM, 80A IFSM, and RoHS compliance. | No functional difference; dual-sourced for supply chain diversification without design change. | Choose when second-source qualification is required for long-term BOM stability in automotive Tier-1 programs. |

FAQ
What is the maximum junction temperature for continuous operation of SB360-B?
The SB360-B is rated for continuous operation with a junction temperature range of –65°C to +125°C. This specification is validated under the stated thermal conditions: RθJA = 30°C/W on FR-4 PCB with 9.5mm lead distance. Exceeding +125°C risks parametric shift and accelerated degradation of the Schottky junction.
Does SB360-B have a specified reverse recovery time (trr)?
No - SB360-B is a Schottky barrier rectifier and exhibits no minority-carrier storage, so reverse recovery time is effectively zero. The datasheet confirms negligible Qrr (reverse recovery charge), making it suitable for high-frequency switching applications where conventional PN-junction diodes would generate significant switching loss and EMI.
Can SB360-B be used in parallel for higher current handling?
Parallel operation is not recommended without external balancing components. Due to VFM mismatch between units (±5% typical), current sharing will be uneven - one device may carry >70% of total load, risking thermal runaway. For >3A requirements, select a single higher-current Schottky (e.g., SB560) or implement active current-sharing circuitry.
Is SB360-B suitable for use in life support equipment?
No - Diodes Incorporated explicitly states that its products, including SB360-B, are not authorized for use as critical components in life support devices or systems without express written approval from the CEO. Its qualification does not cover safety-critical medical applications requiring ASIL or ISO 13485 compliance.
