Product details
Overview
SBL2030PT from Diodes Incorporated is a 20A, 30V Schottky barrier rectifier in TO-3P package, featuring 0.55V forward voltage at 10A/25°C, 250A non-repetitive surge capability, and 2.5°C/W junction-to-case thermal resistance-designed for low-voltage, high-frequency inverters and polarity protection circuits.
For engineers reviewing the SBL2030PT datasheet, SBL2030PT pinout, SBL2030PT application, or SBL2030PT equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance under heatsink mounting, peak repetitive reverse voltage margin, and surge current handling in motor drive freewheeling paths.
Technical Context
This device uses Schottky barrier die with guard ring construction to suppress transient-induced avalanche failure and improve ruggedness during inductive load switching. Its low VF and high IFSM support efficient power conversion in DC-DC stages where conduction loss dominates.
The TO-3P package enables direct heatsink mounting with verified 2.5°C/W RθJC, and its molded plastic case meets UL 94V-0 flammability rating-critical for industrial power supplies requiring thermal reliability and safety compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage; sets upper limit for DC bus or flyback clamp voltage rating |
| IO | 20 A @ TC = 100°C - Continuous average forward current when case temperature is held at 100°C via heatsink |
| VFM | 0.55 V @ IF = 10 A, TC = 25°C - Low conduction loss enabling >92% efficiency in 5–12 V output rectification |
| IFSM | 250 A (8.3 ms half-sine) - Withstands motor startup surges and transformer inrush without degradation |
| RθJC | 2.5 °C/W - Enables thermal design with ≤50°C temperature rise at 20A with standard aluminum heatsink |
| CT | 1100 pF @ 1 MHz, 4 V reverse - Limits high-frequency noise coupling in SMPS secondary-side rectification |
Pinout & Package
TO-3P package: 3-terminal isolated metal tab configuration with anode, cathode, and electrically connected metal case (cathode-connected tab). Mounting hole centered on tab for mechanical fixation and thermal interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input terminal for forward conduction path | Connected to source of energy (e.g., transformer secondary or battery positive in reverse polarity protection) |
| Cathode (Lead 2) | Output terminal for forward conduction path | Delivers rectified current to load; electrically tied to metal tab for low-inductance heatsinking |
| Metal Tab | Cathode terminal and thermal interface | Must be electrically isolated from chassis unless circuit design requires cathode grounding; provides primary thermal path to heatsink |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge breakdown during voltage transients, extending operational life in noisy industrial environments |
| Low VF (0.55 V @ 10 A) | Reduces power dissipation by ≥35% vs. comparable fast recovery diodes, lowering heatsink requirements |
| 250 A IFSM | Supports reliable operation in motor drive freewheeling where peak currents exceed steady-state by 10× |
| TO-3P with UL 94V-0 housing | Enables compliance with IPC-CC-830B insulation and flammability requirements in certified power systems |
Applications
| DC-DC Converter Secondary Rectification | Automotive Battery Polarity Protection |
|---|---|
Use Scenario: Used in 12 V input, 5 V/20 A synchronous buck-derived converter where secondary-side rectification must minimize conduction loss. IC Role / Device Role / Timing Role: Power rectifier conducting during low-side switch off-time; replaces MOSFET synchronous rectifier where gate drive complexity is prohibitive. Use Value: 0.55 V VF limits conduction loss to 5.5 W at full load-enabling passive cooling in space-constrained automotive ECUs. | Use Scenario: Installed inline between vehicle battery and main ECU power rail to prevent damage from accidental reverse battery connection. IC Role / Device Role / Timing Role: Unidirectional current valve; conducts only when battery polarity matches system ground reference. Use Value: 20 A continuous rating handles cold-cranking surge loads; 250 A IFSM survives jump-start transients without fuse activation. |
| Industrial Inverter Freewheeling Diode | UPS Output Stage Clamping |
Use Scenario: Mounted across IGBT collector-emitter in 3-phase VFD output stage to recirculate inductive motor current during PWM dead time. IC Role / Device Role / Timing Role: Freewheeling path for stored magnetic energy; operates at 2–16 kHz switching frequencies. Use Value: Low VF and fast recovery (<10 ns effective) minimize switching losses and reduce heat generation during 100% duty cycle braking events. | Use Scenario: Placed across inverter output filter in line-interactive UPS to clamp overvoltage spikes caused by generator synchronization transients. IC Role / Device Role / Timing Role: Transient voltage clamp; conducts only during >30 V excursions lasting <100 µs. Use Value: Guard ring structure prevents localized avalanche failure during repeated 500 V/10 µs spikes, ensuring 10+ year field reliability. |
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-20CPH03 | Same 30 V VRRM, 20 A IO, but TO-247 package; RθJC = 2.0°C/W; VF = 0.52 V @ 10 A | Lower thermal resistance suits higher ambient temperature enclosures; larger footprint requires PCB re-layout | Select when thermal budget is tighter than mechanical space constraints |
| ON Semiconductor MBR2030CT | 30 V VRRM, dual common-cathode die in TO-220AB; VF = 0.62 V @ 10 A; RθJC = 3.0°C/W | Offers dual-diode configuration for center-tapped transformer designs; lower surge rating (150 A) | Select for cost-sensitive dual-output supplies where layout allows shared cathode routing |
Compared with VS-20CPH03 and MBR2030CT, the SBL2030PT provides optimal balance of thermal performance, surge robustness, and single-diode simplicity in TO-3P-making it preferred for high-reliability freewheeling and polarity protection where mechanical isolation and proven field history matter.

FAQ
Is SBL2030PT RoHS compliant?
Yes, SBL2030PT features lead-free finish and complies with RoHS Directive 2011/65/EU, including exemptions for high-melting-point solder and glass. The device carries "RoHS Compliant" marking per Diodes Incorporated documentation DS23047 Rev. 5.
Can SBL2030PT be used without a heatsink?
No-its 20 A rating assumes case temperature is maintained at ≤100°C via heatsink. At ambient 25°C with no heatsink, derated continuous current is ≤4.5 A per Fig. 1 derating curve; sustained operation above this risks thermal runaway.
What is the maximum operating junction temperature?
The absolute maximum junction temperature is +150°C, and the device is rated for continuous operation from –65°C to +150°C. Thermal design must ensure Tj stays below this limit using RθJC = 2.5°C/W and known heatsink thermal resistance.
Why is SBL2030PT marked "Not Recommended for New Design"?
Diodes Incorporated issued this notice due to newer-generation Schottky rectifiers (e.g., SBRA2030PT) offering improved VF and lower RθJC. However, SBL2030PT remains fully qualified, in active production, and supported for legacy program continuity and obsolescence mitigation.
