Product details
Overview
SB560B from Diodes Incorporated is a 5.0A, 60V Schottky barrier rectifier in DO-201AD package, featuring low forward voltage drop (0.67V @ 5.0A), 150A non-repetitive surge capability, and RoHS-compliant tin-plated leads-designed for polarity protection and free-wheeling in DC-DC converters.
For engineers reviewing the SB560B datasheet, SB560B pinout, SB560B application, or SB560B equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (25°C/W junction-to-ambient), forward voltage at rated current, surge current tolerance, and DO-201AD mechanical compatibility with high-density PCB layouts.
Technical Context
This Schottky rectifier uses epitaxial construction with guard ring die design to suppress transient-induced failure. Its low VF and fast switching enable high-efficiency operation in 60Hz–100kHz power conversion stages without reverse recovery charge.
Thermal performance is defined by two distinct RθJA values: 25°C/W (free-air, 9.5mm lead length) and 8°C/W (junction-to-lead), supporting both through-hole mounting and lead-sink thermal management in industrial power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit in 48V bus polarity protection. |
| IO | 5.0 A - Average rectified output current at TA = 25°C; derated to ~3.2A at 100°C ambient per Fig. 1. |
| VFM | 0.67 V @ 5.0A - Forward voltage drop directly determines conduction loss (3.35W at full load). |
| IFSM | 150 A - Peak surge current rating for 8.3ms half-sine; supports motor startup and capacitor charging transients. |
| RθJA | 25 °C/W - Junction-to-ambient thermal resistance; defines required heatsinking for continuous 5A operation. |
| IRM | 0.5 mA @ 25°C - Reverse leakage at rated blocking voltage; critical for low-power standby efficiency. |
Pinout & Package
DO-201AD axial-leaded package with cathode band marking; body diameter 7.2–9.5 mm, overall length 25.4 mm, lead diameter 1.2–1.3 mm, and lead spacing 4.8–5.3 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current terminal | Connected to unregulated input or inductive flyback node; must withstand full surge current path. |
| Cathode | Output current terminal | Marked with band; ties to regulated rail or ground return; carries full load current with minimal drop. |
Key Features
| Feature | Design Value |
|---|---|
| Epitaxial guard ring die | Suppresses edge breakdown under voltage transients, improving reliability in automotive load-dump environments. |
| Low VF (0.67V) | Reduces conduction loss by >30% vs. comparable silicon rectifiers, enabling higher efficiency in 12V/24V SMPS. |
| 150A IFSM | Withstands repeated inrush events in battery-powered tools and UPS systems without degradation. |
| RoHS-compliant finish | Bright tin plating meets J-STD-202 solderability standards and eliminates lead-based assembly concerns. |
Applications
| DC-DC Converter Output Rectification | Automotive Polarity Protection |
|---|---|
Use Scenario: Used as secondary-side rectifier in isolated 24V-to-5V flyback converter powering infotainment ECUs. IC Role / Device Role / Timing Role: Schottky rectifier conducting during transformer reset phase; replaces slower diodes to minimize switching loss. Use Value: 0.67V VF reduces average conduction loss to 3.35W, lowering thermal stress on PCB copper pours. | Use Scenario: Installed inline between vehicle battery and ECU input to prevent damage from reverse battery connection. IC Role / Device Role / Timing Role: Unidirectional current gate; blocks reverse current while passing full 5A system load. Use Value: 60V VRRM exceeds 42V load-dump spikes, ensuring survival during ISO 7637-2 pulse 5a testing. |
| Industrial Free-Wheeling Diode | AC-DC Adapter Input Bridge |
Use Scenario: Placed across relay coil or solenoid driver MOSFET in PLC output module. IC Role / Device Role / Timing Role: Freewheeling path for inductive kickback energy; clamps voltage spike to <60V. Use Value: 150A IFSM handles 100ms coil de-energization surges without bond-wire fusing. | Use Scenario: One leg of full-wave bridge rectifier in 24V wall adapter supplying PoE injectors. IC Role / Device Role / Timing Role: Half-wave rectifying element in discrete bridge configuration. Use Value: DO-201AD axial form factor allows manual rework and accommodates high-voltage creepage (>5mm) requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB560-T | Same electrical specs; tape-and-reel packaging (1.2K/reel) vs. bulk (500/unit). | Optimized for automated SMT placement; requires pick-and-place feeder setup. | Select for high-volume production where reel feeding improves line efficiency. |
| SS56 | 5A/60V Schottky in DO-214AC (SMC); VF = 0.72V @ 5A; RθJA = 30°C/W. | Surface-mount alternative with higher thermal resistance but smaller footprint. | Choose when board space is constrained and thermal margin allows 0.05V higher VF. |
Compared with SB560B, SB560-T offers identical performance in automated assembly, while SS56 trades 0.05V higher forward drop and +5°C/W thermal resistance for surface-mount compatibility-making SB560B optimal for through-hole prototyping and medium-volume industrial builds requiring manual rework flexibility.

FAQ
What is the maximum junction temperature for SB560B?
The SB560B has a maximum junction temperature of +150°C, validated per its absolute maximum ratings table. This rating enables operation in under-hood automotive environments and enclosed industrial enclosures when mounted with adequate copper area or heatsinking per the derating curve in Figure 1.
Can SB560B replace a standard PN-junction rectifier in a 24V power supply?
Yes-SB560B can directly replace PN rectifiers like 1N5408 in 24V supplies due to its higher current rating (5A vs. 3A), lower VF (0.67V vs. ~1.1V), and absence of reverse recovery time. However, ensure layout accommodates DO-201AD's longer body and verify reverse leakage is acceptable in low-quiescent designs.
Is SB560B suitable for use in a synchronous rectifier circuit?
No-SB560B is a passive Schottky diode, not a synchronous rectifier controller or MOSFET driver. It cannot be actively gated; it operates solely as a unidirectional conduction device. For synchronous rectification, discrete MOSFETs with gate drive signals are required.
What is the lead-free status and RoHS compliance level of SB560B?
SB560B features lead-free, bright tin-plated leads and complies with RoHS Directive 2011/65/EU, including exemptions for high-temperature solder and glass. Compliance is documented in Diodes Incorporated's AP02008 packaging specification and confirmed via material declarations per EU Annex Notes 5 and 7.
