Product details
Overview
SBL6040PT from Diodes Incorporated is a 40V, 60A Schottky barrier rectifier in TO-3P package, designed for low-voltage, high-frequency DC/DC conversion, freewheeling, and polarity protection circuits. It delivers 0.70V forward voltage at 30A and 25°C, supports 500A non-repetitive surge current, and exhibits 1500pF typical junction capacitance at 4V reverse bias.
For engineers reviewing the SBL6040PT datasheet, SBL6040PT pinout, SBL6040PT application, or SBL6040PT equivalent, key selection criteria include its 40V blocking rating, thermal resistance of 0.5°C/W (junction-to-case), 20mA peak reverse leakage at 25°C, and compatibility with heatsink-mounted high-current power rails in industrial SMPS and automotive auxiliary supplies.
Technical Context
This device uses guard ring die construction to enhance transient immunity and prevent premature edge breakdown under repetitive voltage stress. Its Schottky barrier architecture eliminates minority carrier storage, enabling zero reverse recovery time and minimizing switching losses in high-frequency topologies.
The TO-3P package provides robust mechanical mounting and direct thermal path to heatsinks, supporting continuous 60A conduction at case temperature ≤100°C. Junction-to-case thermal resistance is specified at 0.5°C/W when properly mounted, enabling predictable thermal design in compact power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum repetitive reverse voltage before avalanche conduction begins; defines safe operating range in DC bus clamping and reverse polarity protection. |
| IO @ TC=100°C | 60 A - Continuous average forward current capability when case temperature is held at 100°C; requires heatsink design per RθJC = 0.5°C/W. |
| VFM @ IF=30A, TC=25°C | 0.70 V - Forward voltage drop at rated half-load; determines conduction loss (21W at 30A) and impacts efficiency in 12V–48V output stages. |
| IFSM (8.3ms) | 500 A - Peak non-repetitive surge current tolerance; enables survival during inrush events in motor drives and capacitor-input rectifiers. |
| IRM @ VR=40V, TC=25°C | 20 mA - Maximum reverse leakage at full blocking voltage and room temperature; critical for low-power standby and battery-isolation designs. |
| RθJC | 0.5 °C/W - Thermal resistance from junction to case surface; sets minimum heatsink requirement for thermal management in high-power applications. |
| CT @ 1MHz, VR=4V | 1500 pF - Junction capacitance magnitude; influences high-frequency switching node ringing and EMI filter sizing in >100kHz converters. |
Pinout & Package
TO-3P package: molded plastic case (UL 94V-0), 5.6g weight, with three terminals-two anode leads (A1, A2) and one common cathode (K)-arranged in a single-row through-hole configuration for high-current PCB mounting and heatsink interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Primary high-current input terminal; electrically tied internally to A2; used for parallel connection or dual-point soldering to reduce trace inductance. |
| A2 | Anode 2 | Secondary anode terminal; identical internal connection to A1; enables symmetric current distribution and improved thermal spreading on PCB. |
| K | Cathode | Common output terminal; connects to load or ground return; serves as primary thermal interface to heatsink via metal tab mounting. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Prevents edge breakdown under transient overvoltage, improving reliability in unregulated input or load-dump conditions. |
| Low forward voltage (0.70V @ 30A) | Reduces conduction loss by ~30% vs. comparable silicon rectifiers, directly increasing efficiency in 12V/24V/48V DC/DC outputs. |
| High surge rating (500A IFSM) | Withstands repeated cold-start surges in industrial motor controllers without degradation, eliminating need for external snubbers. |
| TO-3P mechanical robustness | Enables secure mechanical retention and stable thermal contact under vibration, meeting requirements for transportation and heavy equipment power systems. |
| RoHS-compliant bright tin terminations | Ensures reliable solderability per MIL-STD-202 Method 208 and compatibility with lead-free reflow profiles in high-volume manufacturing. |

FAQ
Is SBL6040PT still in active production?
No - Diodes Incorporated has marked SBL6040PT as obsolete with no direct replacement offered. The datasheet (DS30050 Rev. 6-4, August 2015) explicitly states "PART OBSOLETE – NO ALTERNATE" and "PART DISCONTINUED". Aetrix Electronics maintains limited legacy stock for design continuity but does not offer new production allocation.
Can SBL6040PT be substituted with SBL6050PT or SBL6060PT?
Yes, but only if the application's maximum reverse voltage remains ≤40V. SBL6050PT (50V) and SBL6060PT (60V) share identical package, thermal performance, and forward characteristics, but higher VRRM increases junction capacitance and may raise EMI in high-frequency designs above 200kHz.
What is the recommended heatsink interface for SBL6040PT?
Mount the TO-3P metal tab directly to an aluminum heatsink using thermal compound (e.g., Dow Corning TC-5022) and M3 screws torqued to 0.5–0.7 N·m. Minimum heatsink thermal resistance must be ≤1.0°C/W to maintain TJ ≤150°C at 60A, assuming ambient ≤50°C and natural convection.
Does SBL6040PT meet AEC-Q101 for automotive use?
No - SBL6040PT is not AEC-Q101 qualified. While it meets RoHS and operates across −65°C to +150°C, Diodes Incorporated does not list it in their AEC-Q101 automotive-grade portfolio. For automotive applications, consider the APx60xxQ series, which undergoes full stress testing per AEC-Q101.
