Product details
Overview
SR2030PTH from Taiwan Semiconductor is a 20A, 30V AEC-Q101 qualified Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 0.55V forward voltage at 10A/25°C, 200A surge capability, and guard ring overvoltage protection for automotive-grade power conversion.
For engineers reviewing the SR2030PTH datasheet, SR2030PTH pinout, SR2030PTH application, or SR2030PTH equivalent, this device supports high-efficiency DC/DC converters, SMPS secondary-side rectification, and automotive infotainment power supplies where low conduction loss and thermal robustness are critical.
Technical Context
This dual-die Schottky rectifier operates with junction temperature range of –55°C to +150°C and exhibits 1.5°C/W junction-to-case thermal resistance. Its 30V repetitive peak reverse voltage (VRRM) and 21V RMS reverse voltage rating define its use in low-voltage, high-current output stages.
The device delivers 500µA maximum reverse leakage at 25°C and 15mA at 100°C under rated VR, enabling stable operation in thermally demanding environments without thermal runaway. Guard ring structure enhances ruggedness against transient overvoltage events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum reverse blocking voltage before breakdown; sets upper limit for output rail voltage in flyback or LLC secondary designs |
| IF | 20 A - Continuous forward current rating; supports 24W–48W output stages at typical 12V–24V bus levels |
| IFSM | 200 A - Non-repetitive surge current (8.3ms half-sine); withstands inrush and short-circuit transients in industrial SMPS |
| VF | 0.55 V @ 10A, 25°C - Low conduction loss reduces heat generation and improves system efficiency by ~0.8% vs. 0.7V alternatives |
| TJ max | +150°C - Extended junction temperature rating enables operation in under-hood automotive environments without derating |
| RθJC | 1.5 °C/W - Enables direct heatsink mounting with minimal thermal interface resistance for compact thermal design |
Pinout & Package
Package: TO-247AD (TO-3P), 3-terminal through-hole package with isolated tab; matte tin-plated leads compliant with J-STD-002 solderability; polarity marked on case.

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 30V VRRM, 20A IF, TO-247AC package; 0.52V VF at 10A but only rated to +125°C TJ | Lacks AEC-Q101 qualification and guard ring; not approved for automotive under-hood use | Select when cost sensitivity outweighs automotive qualification and extended temperature needs |
| ON Semiconductor MUR2030CT | 30V, 20A dual common-cathode fast recovery diode; 1.2V VF, 50ns trr; higher loss, slower switching | Higher conduction loss increases thermal load; suitable only where Schottky EMI concerns exist | Select only if reverse recovery noise must be minimized despite 2.2× higher VF penalty |
Compared with VS-20CPH03-M3 and MUR2030CT, SR2030PTH uniquely combines AEC-Q101 qualification, +150°C operation, and guard ring protection-making it the only choice for thermally aggressive automotive power rails requiring long-term reliability without derating.

FAQ
What is the maximum junction temperature rating for SR2030PTH?
The SR2030PTH has a maximum junction temperature (TJ) rating of +150°C, verified per AEC-Q101 stress testing. This allows uninterrupted operation in under-hood automotive environments and high-ambient industrial settings without current derating up to that limit. The SR2030PTH maintains full 20A IF capability at TJ = 150°C when properly heatsinked.
Is SR2030PTH pin-compatible with other parts in the SR20xPT family?
Yes, all SR20xPT and SR20xPTH variants-including SR2030PTH-share identical TO-247AD (TO-3P) mechanical outline, pin assignment, and terminal configuration. Voltage ratings differ across the family (20V to 150V), but PCB layout, mounting torque (1.13 N·m max), and thermal interface design remain fully interchangeable.
Does SR2030PTH include a guard ring, and what does it do?
Yes, SR2030PTH incorporates a guard ring structure explicitly documented in the datasheet for overvoltage protection. It prevents localized electric field concentration at the die edge during transient reverse-bias events, thereby suppressing premature avalanche breakdown and enhancing long-term reliability in unregulated or noisy power systems.
What is the forward voltage specification for SR2030PTH at 10A and 100°C junction temperature?
The SR2030PTH forward voltage is not specified at 100°C in the datasheet; only 25°C and 125°C data points are provided. At 25°C, VF is 0.55V max at 10A. At 125°C, VF decreases to approximately 0.48V due to negative temperature coefficient of Schottky diodes. Extrapolation to 100°C is not supported by published data.
How does the AEC-Q101 qualification of SR2030PTH impact its use in non-automotive applications?
The AEC-Q101 qualification of SR2030PTH validates its robustness against mechanical shock, temperature cycling, and humidity exposure-making it highly suitable for industrial and harsh-environment applications even outside automotive. Designers benefit from proven reliability margins, extended lifetime prediction, and reduced qualification effort when deploying SR2030PTH in medical, telecom, or outdoor equipment power stages.
