Product details

Overview

B260A-13 from Diodes Incorporated is a 2.0A surface-mount Schottky barrier rectifier in SMA package, rated for 60V peak repetitive reverse voltage (V_RRM), 0.70V max forward voltage at 2.0A, and 50A non-repetitive surge current. It serves as a low-loss freewheeling or polarity protection diode in DC-DC converters and automotive power supplies.

For engineers reviewing the B260A-13 datasheet, B260A-13 pinout, B260A-13 application, or B260A-13 equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance (R_θJL = 25°C/W), surge robustness, RoHS/Green compliance, and AEC-Q101 qualification status.

Technical Context

This Schottky rectifier uses guard ring die construction to enhance transient immunity and supports high-frequency switching up to several MHz due to low junction capacitance (200 pF at 40V). Its low V_F and fast recovery enable high-efficiency operation in low-voltage (<60V) power conversion stages.

The device operates across –65°C to +150°C with thermal resistance of 25°C/W (junction-to-lead), and is qualified to AEC-Q101 standards-electrically and thermally identical to standard-grade parts except for extended reliability testing and PPAP capability.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60 V - Maximum reverse blocking voltage before breakdown; sets upper limit for input/output rail isolation in 48V systems.
I_O	2.0 A - Continuous average forward current at +25°C ambient; derates to ~1.5A at +100°C per Fig. 4.
V_F @ 2.0A	0.70 V max - Low conduction loss enables >92% efficiency in 5–12V buck converters at full load.
I_FSM	50 A - Peak surge rating for 8.3ms half-sine; withstands inrush in automotive cold-crank scenarios.
R_θJL	25 °C/W - Junction-to-lead thermal resistance; enables direct PCB copper pour heatsinking without external heatsink.
C_T @ 40V	200 pF - Low junction capacitance minimizes switching losses and EMI in high-frequency SMPS (>100 kHz).
I_R @ 60V	0.5 mA max @ +25°C - Low leakage preserves battery standby time in always-on automotive modules.

Pinout & Package

Package: SMA (DO-214AC), surface-mount plastic case with cathode band marking; UL 94V-0 rated, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential side (e.g., switch node in buck converter); requires adequate copper area for thermal dissipation.
Cathode	Forward current exit / reverse blocking terminal	Marked by band; ties to higher-potential rail (e.g., output capacitor positive); defines polarity protection direction.

Key Features

Feature	Design Value
Guard ring die construction	Improves ESD and transient surge immunity without external TVS, reducing BOM count in automotive ECUs.
AEC-Q101 qualification	Validated for automotive under-hood applications including engine control and lighting modules.
Lead-free & Halogen-free	Meets RoHS 2 and "Green" requirements (<900 ppm Br/Cl, <1000 ppm Sb); compliant for global automotive Tier-1 supply chains.
High-temp solderability	Rated for 260°C/10 sec reflow-compatible with standard lead-free PCB assembly processes.

Applications

Automotive Lighting Control

USB-C Power Delivery Clamp

Use Scenario: Reverse polarity protection for LED headlamp drivers exposed to battery jump-start transients.

IC Role / Device Role / Timing Role: Unidirectional blocking diode placed between battery input and DC-DC controller.

Use Value: 50A I_FSM withstands 12V cold-crank surges; 0.70V V_F limits power loss to <1.4W at 2A, avoiding thermal runaway.

Use Scenario: Input polarity clamp on 20V USB-PD input stage of portable medical monitors.

IC Role / Device Role / Timing Role: Freewheeling path during synchronous rectifier dead-time; prevents shoot-through.

Use Value: 200 pF C_T minimizes capacitive coupling noise into analog sensor rails; 25°C/W R_θJL allows direct pad thermal relief.

Industrial 24V PLC I/O Module

5G Small Cell DC Power Rail

Use Scenario: Output rectification in isolated 24V auxiliary supply feeding digital I/O isolators.

IC Role / Device Role / Timing Role: Secondary-side Schottky rectifier in flyback converter operating at 250 kHz.

Use Value: Low V_F improves light-load efficiency critical for energy-harvesting gateways; AEC-Q101 grade ensures long-term field reliability.

Use Scenario: Polarity protection on +48V DC input of remote radio unit (RRU) power board.

IC Role / Device Role / Timing Role: Reverse-blocking diode in hot-swap circuit protecting downstream GaN FETs.

Use Value: 60V V_RRM provides 20% margin over 48V nominal; 0.5 mA I_R prevents standby current drain in always-on baseband units.

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 V_RRM, 2A I_O, but SMB package (R_θJL = 20°C/W); VF = 0.72V max @ 2A.	SMB offers slightly better thermal performance but larger footprint; not pin-compatible with SMA.	Select when board layout allows SMB and thermal margin is prioritized over space.
SS26 (ON Semiconductor)	60V V_RRM, 2A I_O, SMA package; VF = 0.75V max @ 2A; no AEC-Q101 qualification.	Lacks automotive qualification; leakage higher (1.0 mA max @ 60V).	Acceptable for industrial consumer designs where AEC-Q101 is not mandated.

Compared with SB260-E3/52 and SS26, B260A-13 uniquely combines SMA footprint, AEC-Q101 qualification, and 0.70V V_F-making it optimal for space-constrained automotive modules requiring production traceability and transient robustness.

FAQ

Is B260A-13 qualified for automotive use?

Yes. B260A-13 is AEC-Q101 qualified and PPAP-capable. It undergoes extended reliability testing-including temperature cycling, HTRB, and ESD-while maintaining identical electrical and thermal specs as standard-grade parts. Automotive qualification is explicitly stated in the ordering information table and confirmed in Diodes' product compliance documentation.

What is the maximum operating temperature for continuous 2.0A current?

At 2.0A DC, the maximum ambient temperature for continuous operation is approximately 85°C, based on the derating curve (Fig. 4) and R_θJL = 25°C/W. At higher ambient temperatures, current must be reduced linearly; for example, at +100°C ambient, I_O is derated to ~1.5A to maintain T_J ≤ +150°C.

Does B260A-13 have a cathode notch or band marking?

Yes. Per mechanical data, B260A-13 uses a cathode band marking on the SMA package body. The band identifies the cathode terminal, which must be connected toward the higher-potential side of the circuit for correct polarity protection or freewheeling operation.

Can B260A-13 replace B260-13 in existing designs?

Yes, with verification. B260A-13 (SMA) and B260-13 (SMB) share identical electrical specs but differ in package: SMA has smaller footprint and higher R_θJL (25 vs. 20°C/W). Layout adaptation is required; thermal performance must be re-evaluated if substituting into an SMB-designed board.
