Product details

Overview

SBL3060PT from Diodes Incorporated is a 30A, 60V Schottky barrier rectifier in TO-3P package, featuring low forward voltage drop (0.70 V @ 15 A, 25°C), high surge capability (275 A, 8.3 ms), and thermal resistance of 2.0°C/W - used for polarity protection and free-wheeling in DC-DC converters and industrial power supplies.

For engineers reviewing the SBL3060PT datasheet, SBL3060PT pinout, SBL3060PT application, or SBL3060PT equivalent, key selection criteria include peak reverse voltage rating, forward voltage vs. temperature behavior, junction-to-case thermal resistance, and surge current derating under capacitive loads.

Technical Context

This dual-anode common-cathode Schottky rectifier uses guard ring die construction to enhance transient robustness and reduce leakage drift at elevated temperatures. Its low V_F and fast switching enable high-efficiency operation in low-voltage, high-frequency power conversion stages without reverse recovery loss.

The device is rated for continuous 30 A average output current at T_C = 95°C with mandatory heatsinking, and exhibits 1100 pF typical junction capacitance at 4 V reverse bias and 1 MHz - critical for EMI-sensitive flyback and synchronous rectifier designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60 V - maximum non-repetitive reverse voltage before breakdown; defines safe operating limit in unidirectional blocking applications.
I_O	30 A @ T_C = 95°C - continuous DC output current capacity when mounted on heatsink; requires thermal design margin below 95°C case temp.
V_FM	0.70 V @ I_F = 15 A, T_C = 25°C - forward conduction loss directly impacts system efficiency and heatsink sizing.
I_FSM	275 A, 8.3 ms half-sine - short-duration surge rating; determines survivability during input line transients or motor startup events.
R_θJC	2.0°C/W - thermal resistance from junction to case; enables calculation of junction temperature rise above heatsink temperature.
C_T	1100 pF @ V_R = 4 V, f = 1 MHz - junction capacitance affects high-frequency switching noise and snubber design in SMPS.
I_RM	75 mA @ T_C = 100°C - reverse leakage at max operating temperature; influences standby power loss in always-on circuits.

Pinout & Package

Package: TO-3P - molded plastic case (UL 94V-0), 5.6 g weight, tin-plated terminals solderable per MIL-STD-202 Method 208. Polarity marked on body; cathode is common terminal.

Pin/Terminal	Circuit Role	Design Meaning
Anode 1	Input terminal for first rectifying path	Accepts AC or switched DC input; connects to transformer secondary or switching node in freewheeling configuration.
Anode 2	Input terminal for second rectifying path	Enables dual-input or parallel-path layout; electrically isolated from Anode 1 but shares cathode.
Cathode	Common output terminal	Delivers rectified DC output; must be thermally coupled to heatsink due to shared power dissipation path.

Key Features

Feature	Design Value
Guard ring die construction	Improves transient voltage immunity and stabilizes reverse leakage across temperature range.
Low forward voltage drop	Reduces conduction loss by ~30% vs. comparable silicon diodes, lowering thermal load in 12–48 V systems.
High surge current rating	Supports 275 A non-repetitive surges, enabling use in motor drive snubbers and inductive load commutation.
TO-3P mechanical robustness	UL 94V-0 flammability rating and 2.0°C/W R_θJC allow reliable operation in industrial enclosures with forced-air or passive cooling.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-30CPH06	Same 60 V V_RRM, 30 A I_O, but TO-247 package; R_θJC = 1.7°C/W; V_F = 0.72 V @ 15 A.	Higher thermal performance but larger footprint; requires different mounting hardware and PCB cutout.	Select when lower junction temperature is prioritized over board space and legacy TO-3P compatibility.
ON Semiconductor MBR3060CT	Identical TO-220AB package pinout; V_F = 0.75 V @ 15 A; I_FSM = 220 A; R_θJC = 2.5°C/W.	Limited surge margin and higher thermal resistance; unsuitable for high-transient industrial environments.	Acceptable only in cost-sensitive, low-surge consumer power supplies where heatsink area is abundant.

Compared with VS-30CPH06 and MBR3060CT, the SBL3060PT offers optimal balance of TO-3P mechanical compatibility, 275 A surge headroom, and 2.0°C/W thermal resistance - making it preferred for retrofitting legacy industrial power designs requiring field-proven reliability.

FAQ

Is the SBL3060PT RoHS compliant?

Yes, the SBL3060PT features a lead-free finish and complies with RoHS Directive 2011/65/EU, including exemptions for glass and high-temperature solder per Annexes 5 and 7. Certificate of Compliance is available upon request from Diodes Incorporated.

What is the maximum allowable case temperature for continuous operation?

The SBL3060PT is rated for 30 A average output current at T_C = 95°C. Operation above this temperature requires linear derating per Figure 1 in the datasheet - e.g., 22 A at 110°C - and must maintain junction temperature ≤150°C with appropriate heatsinking.

Can the SBL3060PT be used in parallel configurations?

Yes, but only with matched devices and symmetrical PCB layout. Due to V_F mismatch, forced current sharing via individual ballast resistors or active balancing is recommended for >20 A total current to prevent thermal runaway.

Why is the SBL3060PT marked "Not Recommended for New Design"?

This designation reflects Diodes Incorporated's internal roadmap shift toward newer-generation Schottky rectifiers with improved V_F/I_RM trade-offs and enhanced surge robustness. The SBL3060PT remains fully qualified and supported for existing designs and legacy replacements.
