Product details
Overview
SR2030PT from Taiwan Semiconductor is a 20A, 30V Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring low forward voltage (0.55 V @ 10 A, 25°C), high surge current capability (200 A), and AEC-Q101 qualification option. It serves as a primary output rectifier in high-efficiency SMPS for consumer power adapters and DC-DC converters.
For engineers reviewing the SR2030PT datasheet, SR2030PT pinout, SR2030PT application, or SR2030PT equivalent, key selection criteria include its 30 V repetitive peak reverse voltage, 1.5 °C/W junction-to-case thermal resistance, dual-die configuration, and compatibility with lead-free reflow soldering per J-STD-002.
Technical Context
The SR2030PT uses a dual-die Schottky structure optimized for low conduction loss and fast switching, with guard ring protection against transient overvoltage. Its 30 V VRRM rating targets mid-voltage secondary-side rectification where efficiency and thermal management are critical.
Rated for continuous 20 A forward current at case temperature up to 125°C (or 150°C for AEC-Q101 versions), it delivers stable performance under high ripple conditions typical in 60–100 kHz SMPS topologies, supported by 200 A non-repetitive surge capability and 500 µA max reverse leakage at 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage; defines safe operating range in secondary-side rectification circuits |
| IF | 20 A - Continuous average forward current; supports high-power adapter and converter outputs without forced air cooling |
| IFSM | 200 A - Peak non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients in power supplies |
| VF | 0.55 V @ 10 A, 25°C - Low forward drop reduces conduction loss and improves system efficiency above 90% |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance enables direct heatsink mounting for thermal management in compact designs |
| IR | 500 µA @ 30 V, 25°C - Reverse leakage current; low value minimizes standby power loss in energy-efficient designs |
| TJ max | 125°C (standard), 150°C (AEC-Q101 version) - Maximum junction temperature determines derating curve and long-term reliability margin |
Pinout & Package
Package: TO-247AD (TO-3P) - Industry-standard 3-lead through-hole power package with isolated metal tab for direct heatsink mounting and high thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current entry point | Connected to transformer secondary or switch node; must be routed with low-inductance path for EMI control |
| Cathode (Lead 2) | Output current exit point | Connects to output capacitor and load; polarity marking on device body confirms orientation |
| Case / Tab (Lead 3) | Thermal and electrical ground reference | Electrically connected to cathode; requires insulating pad if mounted to grounded heatsink |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Enhances ruggedness against transient overvoltage events without external snubbers in SMPS flyback designs |
| AEC-Q101 qualification option | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
| Matte tin-plated leads | Ensures consistent solderability and intermetallic formation during lead-free reflow (J-STD-002 compliant) |
| UL Recognized (E-326243) | Confirms flammability (UL 94V-0), creepage, and clearance compliance for safety-critical AC/DC power supplies |
| Dual-die configuration | Provides redundancy and improved current sharing versus single-die devices of same rating |

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-M3 | Same 30 V VRRM, 20 A IF, but TO-247AC package (non-isolated tab); RθJC = 1.7 °C/W | Requires insulated mounting hardware when heatsink is grounded; slightly higher thermal resistance limits power density | Select when cost sensitivity outweighs thermal margin needs and isolation is managed externally |
| ON Semiconductor MUR2030CT | 30 V, 20 A ultrafast recovery diode (not Schottky); VF ≈ 0.95 V; higher switching loss | Suitable only where reverse recovery noise is acceptable; not recommended for >100 kHz SMPS | Choose only for legacy designs requiring ultrafast recovery, not for new high-efficiency Schottky-based layouts |
Compared with VS-20CPH03-M3 and MUR2030CT, the SR2030PT offers lower forward voltage, isolated tab for simplified thermal design, and AEC-Q101 qualification path-making it optimal for next-generation compact, high-efficiency, and automotive-adjacent power supplies.

FAQ
What is the maximum junction temperature rating for SR2030PT?
The SR2030PT has a maximum junction temperature (TJ) of 125°C for standard versions. An AEC-Q101 qualified variant supports up to 150°C, verified per JESD22-A108 stress testing. Derating begins above 25°C case temperature, following the forward current derating curve in the official datasheet. Thermal design must account for RθJC = 1.5 °C/W and interface resistance to heatsink.
Is SR2030PT pin-compatible with other SR20xxPT variants?
Yes, all SR20xxPT devices-including SR2030PT-share identical TO-247AD (TO-3P) mechanical outline, pin assignment, and terminal configuration. Voltage ratings (20 V to 150 V) are the only functional difference; layout reuse is fully supported across the family without PCB modification.
Does SR2030PT have an isolated tab, and how does that affect mounting?
Yes, the SR2030PT features an electrically isolated metal tab (Lead 3) connected internally to the cathode. This allows direct mounting to a grounded heatsink without insulation hardware-reducing thermal resistance and simplifying assembly. If the heatsink is not grounded, standard mounting applies; polarity marking on the device body confirms cathode orientation.
What is the reverse leakage current specification for SR2030PT at elevated temperature?
At 30 V reverse bias and 100°C junction temperature, SR2030PT exhibits a maximum reverse current (IR) of 15 mA. At 125°C, leakage rises further but remains within safe operational limits for SMPS applications. This value is confirmed in the Electrical Specifications table of the J2103 datasheet revision and reflects worst-case behavior under thermal stress.
Can SR2030PT be used in automotive applications?
Yes-SR2030PT is available in an AEC-Q101 qualified version (marked SR2030PTH), which undergoes extended reliability testing including temperature cycling, HTRB, and ESD per AEC-Q101-004/005/006. The standard SR2030PT is not automotive-qualified; only the "H" suffix variant meets automotive component requirements.
