Product details
Overview
SB360-T 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 IEC 61000-4-2 ±15kV ESD protection. It serves as a low-loss freewheeling diode in DC-DC converters and polarity protection switch in automotive power modules.
For engineers reviewing the SB360-T datasheet, SB360-T pinout, SB360-T application, or SB360-T 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
This Schottky rectifier uses guard ring die construction to suppress transient-induced junction breakdown and sustain 80A peak surge under 8.3ms half-sine conditions. Its low forward voltage minimizes conduction loss in high-frequency switching topologies where duty cycle and thermal management are critical.
The device operates from –65°C to +125°C with a maximum junction temperature of +150°C and exhibits 0.5mA peak reverse leakage at 25°C and 20mA at 100°C - enabling stable performance in thermally constrained industrial power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in polarity protection and flyback clamp circuits. |
| VFM @ 3.0A | 0.74 V - Forward voltage drop at rated DC current; directly determines conduction loss (2.22W) and thermal rise in continuous operation. |
| IFSM | 80 A - Non-repetitive surge rating for 8.3ms; supports inrush current handling in motor drive snubbers and capacitor charging paths. |
| RθJA | 30 °C/W - Junction-to-ambient thermal resistance; used to calculate max ambient temperature for 125°C junction limit at 3.0A load. |
| IRM @ 25°C | 0.5 mA - Peak reverse leakage at rated VRRM and 25°C; impacts standby power loss in battery-backed systems. |
| Polarity | Cathode band - Unambiguous terminal identification for PCB layout; prevents reverse installation in high-current power rails. |
Pinout & Package
DO-201AD axial-leaded plastic package with cathode band marking; 25.4mm body length, 7.2–9.5mm body width, 1.2–1.3mm lead diameter, and 4.8–5.3mm lead spacing. Weight: ~1.1g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to lower-potential node (e.g., ground side of inductive load) in freewheeling path. |
| Cathode | Current exit point during forward conduction; marked with band | Connected to higher-potential node (e.g., supply rail) - reverse bias blocks current in polarity protection. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Enhances transient immunity by preventing edge breakdown during voltage spikes in automotive load-dump events. |
| Low forward voltage (0.74V @ 3A) | Reduces power dissipation by >30% vs. comparable silicon rectifiers, lowering heatsink requirements in compact adapters. |
| 80A surge rating | Supports single-event overcurrent survival without degradation in motor control H-bridge freewheeling paths. |
| IEC 61000-4-2 ±15kV ESD contact | Enables direct integration into unshielded automotive subassemblies without external ESD protection components. |
Applications
| DC-DC Converter Freewheeling | Automotive Polarity Protection |
|---|---|
Use Scenario: Used across synchronous buck converter output in-ductor to provide low-loss current recirculation path during high-side FET off-time. IC Role / Device Role / Timing Role: Passive freewheeling diode; conducts only during discontinuous conduction mode (DCM) or when synchronous rectification is disabled. Use Value: 0.74V VFM reduces average conduction loss to 2.22W at 3A, improving efficiency by ≥1.8% over 1.0V silicon alternatives. | Use Scenario: Placed in series with battery input on infotainment head units to prevent damage from reverse battery connection. IC Role / Device Role / Timing Role: Unidirectional current gate; blocks reverse current flow while passing full 3A system load with minimal voltage drop. Use Value: 60V VRRM withstands ISO 7637-2 pulse 5a (load dump up to 60V), eliminating need for additional TVS clamping. |
| Industrial AC/DC Input Rectification | High-Frequency Inverter Output Clamp |
Use Scenario: Half-wave rectifier in auxiliary 12V bias supply for PLC I/O modules operating from 24VAC field power. IC Role / Device Role / Timing Role: Low-loss rectifying element; conducts during positive half-cycle with minimal heating at 50/60Hz line frequency. Use Value: 30°C/W RθJA allows operation at 50°C ambient without derating - enabling fanless enclosure designs. | Use Scenario: Connected across IGBT collector-emitter in solar microinverter H-bridge to clamp inductive kickback during switching transitions. IC Role / Device Role / Timing Role: Snubber diode; provides fast, low-VF path for stored inductor energy, reducing voltage overshoot stress on switching devices. Use Value: 80A IFSM handles worst-case 60Hz grid-synchronous surges without thermal runaway or bond-wire fusing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS36-E3/57T (Vishay) | Same DO-201AD package, 3.0A/60V rating, but VFM = 0.70V @ 3A and RθJA = 35°C/W. | Slightly lower conduction loss but higher thermal resistance limits ambient operating range. | Prefer for ultra-low-loss priority in forced-air-cooled systems; avoid in sealed enclosures above 45°C ambient. |
| MBR360RLG (ON Semiconductor) | Identical electrical specs (60V/3A/0.74V), but qualified to AEC-Q101 and shipped in 1000/reel tape. | Approved for automotive production use with PPAP documentation; SB360-T lacks AEC qualification. | Select for Tier-1 automotive programs requiring change-controlled qualification; SB360-T suits industrial prototypes and cost-sensitive BOMs. |
Compared with SS36-E3/57T and MBR360RLG, SB360-T offers optimal balance of thermal performance (30°C/W), ESD robustness (±15kV), and cost for industrial power conversion - though it lacks AEC-Q101 certification required for automotive production deployment.

FAQ
What is the maximum junction temperature for SB360-T?
The absolute maximum junction temperature is +150°C, with continuous operation rated up to +125°C. Derating begins at +25°C ambient per Figure 1: at 3.0A, maximum allowable ambient is 95°C when using standard PCB copper pad layout (2.5" × 2.5") per datasheet Note 7.
Is SB360-T suitable for automotive production use?
No - SB360-T is not AEC-Q101 qualified and lacks PPAP documentation. While it meets basic environmental specs (–65°C to +150°C, ±15kV ESD), Diodes recommends MBR360RLG or SB360Q for automotive production due to formal qualification and IATF 16949 manufacturing compliance.
How does the DO-201AD package affect thermal performance?
DO-201AD's axial leads and molded plastic body yield RθJA = 30°C/W and RθJL = 10°C/W. Thermal performance depends heavily on PCB copper area: the 30°C/W value assumes a 2.5" × 2.5" copper pad. Reducing pad size to 1" × 1" increases RθJA to ~55°C/W, limiting usable current to ~1.8A at 50°C ambient.
What is the reverse recovery behavior of SB360-T?
As a Schottky barrier rectifier, SB360-T has no minority-carrier storage and therefore exhibits zero reverse recovery time (trr ≈ 0 ns) and negligible reverse recovery charge (Qrr ≈ 0 nC). This eliminates switching losses and EMI associated with silicon PN-junction diodes in high-frequency (>100kHz) applications.
