Diodes Incorporated SBL1060

Overview

SBL1060 from Diodes Incorporated is a 10A, 60V Schottky barrier rectifier in TO-220AC package, featuring low forward voltage drop (0.75 V @ 10 A, 25°C), high surge capability (250 A, 8.3 ms), and thermal resistance of 3.5°C/W junction-to-case. It is designed for low-voltage, high-frequency inverters, freewheeling diode applications, and polarity protection circuits in power supplies and DC-DC converters.

For engineers reviewing the SBL1060 datasheet, SBL1060 pinout, SBL1060 application, or SBL1060 equivalent, key selection criteria include peak reverse voltage rating (60 V), average output current at TC = 95°C (10 A), forward voltage drop under load, surge current tolerance, and thermal performance in heatsink-mounted configurations.

Technical Context

The SBL1060 employs a Schottky barrier chip with guard ring die construction to enhance transient protection and reduce leakage. Its unidirectional single-diode topology supports half-wave rectification in 60 Hz AC line applications and high-frequency switching circuits up to several hundred kHz.

Designed for operation with resistive or inductive loads, it requires 20% current derating for capacitive loads. The device operates across –65°C to +150°C junction temperature range and exhibits typical junction capacitance of 700 pF at 4.0 V reverse bias and 1.0 MHz.

FAQ

Is SBL1060 still in active production?

No. Per Diodes Incorporated's DS23042 Rev. 5 (August 2015), SBL1060 is marked "OBSOLETE – PART DISCONTINUED" with no alternate part offered. Aetrix Electronics maintains limited legacy stock for design continuity and repair programs, but no new production runs exist.

What is the pin configuration for SBL1060 in TO-220AC package?

SBL1060 uses a 2-lead TO-220AC package: Pin 1 (left lead, viewed with tab facing away) is the anode; Pin 2 (right lead) is the cathode; the metal tab is internally connected to the anode and serves as both thermal path and electrical terminal.

Can SBL1060 replace SBL1045 in a 45 V design?

Yes - SBL1060's 60 V VRRM exceeds SBL1045's 45 V rating, maintaining full blocking margin. Its higher VFM (0.75 V vs. 0.60 V for SBL1045) increases conduction loss slightly, but thermal design remains viable given identical package and RJC.

Does SBL1060 require a heatsink in 10 A operation?

Yes. At 10 A average current and TA = 25°C, junction temperature exceeds 150°C without heatsinking. The datasheet specifies IO = 10 A only at TC = 95°C, meaning a heatsink capable of maintaining case temperature ≤95°C is mandatory for rated operation.
