Product details
Overview
B260-13 from Diodes Incorporated is a 2.0A surface-mount Schottky barrier rectifier in SMB package, rated for 60V peak repetitive reverse voltage, 0.70V max forward voltage at 2.0A, and 50A non-repetitive surge current; used for polarity protection and free-wheeling in low-voltage DC/DC converters and automotive body control modules.
For engineers reviewing the B260-13 datasheet, B260-13 pinout, B260-13 application, or B260-13 equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance (20°C/W junction-to-lead), reverse leakage at 100°C, surge capability, and AEC-Q101 qualification status for automotive deployment.
Technical Context
This Schottky rectifier employs guard ring die construction to suppress transient-induced avalanche breakdown and supports high-frequency switching up to several MHz due to low junction capacitance (200 pF at 40V). Its low VF enables reduced conduction loss in 5–24V power rails.
Designed for surface-mount reflow assembly with +260°C/10s soldering tolerance, it features matte tin-plated terminals compliant with MIL-STD-202 Method 208 and moisture sensitivity level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum reverse blocking voltage before breakdown; sets upper limit for input voltage in buck converter freewheeling path |
| IF(AV) | 2.0 A - Continuous average forward current rating at TA = +25°C; derates to ~1.2A at +100°C ambient |
| VF @ 2.0A | 0.70 V max - Forward voltage drop defining conduction loss (1.4W max at 2A); lower than silicon diodes by ~0.2–0.3V |
| IFSM | 50 A - Single half-sine surge rating (8.3ms); withstands inrush in motor drive clamp circuits |
| RθJL | 20 °C/W - Junction-to-lead thermal resistance in SMB package; enables direct PCB copper pour heat sinking |
| IR @ VR | 20 mA max @ +100°C - Reverse leakage at full rated voltage and elevated temperature; impacts standby power in always-on systems |
| CT @ 40V | 200 pF - Junction capacitance limiting high-frequency switching noise and EMI in SMPS output stages |
Pinout & Package
SMB (DO-214AA) surface-mount plastic package with cathode band marking; 2-terminal device: anode and cathode. Dimensions: 4.06–4.57 mm (L) × 1.96–2.21 mm (W) × 2.30 mm (H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node in buck converter); must route with low-inductance trace |
| Cathode | Forward current exit / reverse-blocking terminal | Marked with band; ties to output rail or ground return; determines polarity protection direction |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB260-E3/52 (Vishay) | Same 60V VRRM, 2A IF(AV), but VF = 0.72V max @ 2A; RθJL = 22°C/W (SMB) | No AEC-Q101 qualification; not approved for automotive under-hood use | Select only for industrial/commercial designs where automotive qualification is unnecessary |
| SS26 (ON Semiconductor) | 60V VRRM, 2A IF(AV), VF = 0.75V max @ 2A; IR = 50mA @ +100°C (higher leakage) | Qualified to AEC-Q101 but lacks guard ring construction; lower transient robustness | Prefer for cost-sensitive automotive interior modules where transient immunity is less critical |
Compared with SB260-E3/52 and SS26, B260-13 delivers superior thermal performance (20°C/W), lower leakage at high temperature, and proven transient resilience via guard ring design-making it optimal for demanding automotive power rails.

FAQ
Is B260-13 pin-compatible with B260A-13-F?
No. B260-13 uses the SMB (DO-214AA) package, while B260A-13-F uses SMA (DO-214AC). Though both are 2-terminal Schottky rectifiers with identical electrical specs, their footprints differ: SMB is larger (4.57 mm × 2.21 mm) versus SMA (2.92 mm × 1.63 mm), requiring separate PCB layouts and stencil apertures.
What is the maximum operating temperature for continuous 2.0A operation?
At 2.0A DC, the junction temperature must remain ≤150°C. With RθJL = 20°C/W and typical PCB copper pour, ambient temperature must be ≤110°C to maintain safe operation. Derating curves show usable current drops to ~1.2A at +100°C ambient per Figure 4 in DS13004 Rev. 22.
Does B260-13 meet PPAP requirements for automotive production?
Yes. As an AEC-Q101-qualified part, B260-13 supports Production Part Approval Process (PPAP) Level 3 documentation upon request. Diodes Incorporated provides certified test reports, process flow diagrams, and control plans aligned with AIAG standards for automotive Tier 1 suppliers.
Can B260-13 replace a 1N5822 in existing designs?
Yes, with layout revision. B260-13 matches 1N5822's 3A rating and 40V VRRM only partially-it is rated for 60V VRRM and 2A IF(AV), not 3A. Its lower VF (0.70V vs. ~0.9V) improves efficiency, but current capacity is reduced; verify thermal margin and peak surge needs before substitution.
