Product details
Overview
SR2030 from Taiwan Semiconductor is a 20A, 30V repetitive peak reverse voltage Schottky barrier rectifier in TO-220AB package with dual-die configuration, 0.55V forward voltage at 10A/25°C, 200A surge capability, and AEC-Q101 qualification option (SR2030H). It serves as primary output rectifier in high-efficiency DC-DC converters.
For engineers reviewing the SR2030 datasheet, SR2030 pinout, SR2030 application, or SR2030 equivalent, key selection criteria include its 30V VRRM, low 0.55V VF at rated current, 125°C max junction temperature, TO-220AB thermal resistance of 1°C/W, and suitability for automotive-grade power conversion where low conduction loss and robust surge handling are critical.
Technical Context
This Schottky rectifier uses guard ring structure to enhance overvoltage ruggedness and supports high dv/dt (10,000 V/μs), enabling reliable operation in fast-switching topologies. Its dual-die TO-220AB construction delivers 20A continuous forward current with junction-to-case thermal resistance of 1°C/W.
The device operates across -55°C to +125°C junction range (150°C for AEC-Q101 variant), exhibits 500µA max reverse leakage at 25°C and rated VR, and maintains 15mA IR at 100°C - confirming stable performance under elevated thermal stress in compact power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum reverse blocking voltage before breakdown; defines usable input/output voltage margin in 24V systems. |
| IF | 20 A - Continuous forward current rating; determines minimum heatsink sizing for sustained load conditions. |
| VF @ 10A, 25°C | 0.55 V - Low conduction loss per diode; reduces power dissipation by ~5.5W vs. higher-VF alternatives at 10A. |
| IFSM | 200 A - Non-repetitive surge current capacity; withstands inrush and fault transients without failure. |
| RθJC | 1 °C/W - Junction-to-case thermal resistance; enables direct mounting to heatsink with predictable temperature rise. |
| TJ max | 125 °C - Maximum operating junction temperature; sets thermal design ceiling for ambient + power loss calculations. |
| IR @ 25°C | 500 µA - Reverse leakage at rated VRRM; ensures minimal standby power loss in offline supplies. |
Pinout & Package
TO-220AB package with isolated tab (case), 3-terminal configuration: Anode 1, Cathode (common), Anode 2. Tab is electrically isolated and thermally conductive; mounting torque ≤ 0.56 N·m. Matte tin-plated leads comply with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 (Left) | Anode 1 | Input connection for first Schottky die; used in dual-output or interleaved rectification. |
| Terminal 2 (Center) | Cathode (Common) | Shared cathode node; carries full 20A output current; electrically tied to isolated metal tab. |
| Terminal 3 (Right) | Anode 2 | Input connection for second Schottky die; enables synchronous or dual-path rectifier layout. |
Key Features
| Feature | Design Value |
|---|---|

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-20BQ030 | Same 30V VRRM, 20A IF, but TO-220AC package (non-isolated tab); 0.52V VF at 10A. | Requires insulating hardware for heatsink mounting; lower VF offers marginal efficiency gain. | Select when thermal interface simplicity outweighs isolation needs and AEC-Q101 is not required. |
| ON Semiconductor SB2030 | 30V VRRM, 20A IF, TO-220AB, but only rated to 125°C TJ (no AEC-Q101 option); 0.58V VF. | Lacks automotive qualification and has slightly higher conduction loss. | Choose for cost-sensitive industrial designs where automotive compliance is unnecessary. |
Compared with VS-20BQ030 and SB2030, the SR2030 provides electrically isolated TO-220AB mounting and optional AEC-Q101 qualification - critical for automotive and safety-isolated industrial systems - while maintaining competitive VF and thermal performance.

FAQ
What is the maximum junction temperature rating for SR2030?
The SR2030 has a maximum junction temperature (TJ) of 125°C under standard operating conditions. This rating applies to the base SR2030 part; the AEC-Q101 qualified variant SR2030H extends TJ to 150°C. Thermal design must ensure junction temperature remains below this limit during worst-case power dissipation and ambient conditions.
Does SR2030 have an electrically isolated tab?
Yes, the SR2030 uses a TO-220AB package with an electrically isolated metal tab. The tab is thermally conductive but not internally connected to any terminal, allowing direct mounting to grounded heatsinks without insulation hardware - a key advantage over TO-220AC variants like VS-20BQ030.
What is the forward voltage specification for SR2030 at 20A?
The SR2030 datasheet specifies forward voltage (VF) at 10A and 25°C as 0.55V typical. At 20A, VF rises due to resistive and thermal effects; extrapolation from the typical forward characteristic curve (Fig.4) shows ~0.62V at 20A/25°C. Derating is required at higher temperatures.
Is SR2030 suitable for use in automotive applications?
The base SR2030 is not AEC-Q101 qualified, but the SR2030H variant is fully AEC-Q101 certified for automotive power systems. Engineers selecting SR2030 for automotive use must specify the 'H' suffix to ensure qualification for temperature cycling, mechanical shock, and humidity testing per AEC standards.
What packaging options are available for SR2030?
SR2030 is supplied in TO-220AB package, packed 50 units per tube. The ordering code SR2030 denotes the standard version; SR2030H indicates the AEC-Q101 qualified variant. Both share identical electrical specs and mechanical dimensions, differing only in qualification test documentation and traceability.
