Product details
Overview
SR3030PTH from Taiwan Semiconductor is a 30A, 30V AEC-Q101-qualified Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 0.55V forward voltage at 15A/25°C, 300A surge capability, and guard ring overvoltage protection-used in automotive-grade DC-DC converters and SMPS secondary-side rectification.
For engineers reviewing the SR3030PTH datasheet, SR3030PTH pinout, SR3030PTH application, or SR3030PTH equivalent, key selection criteria include repetitive peak reverse voltage (30 V), junction-to-case thermal resistance (1.5 °C/W), TJ max rating (150 °C), UL recognition (E-326243), and halogen-free compliance per IEC 61249-2-21.
Technical Context
This dual-die Schottky rectifier operates with low conduction loss and high thermal robustness, enabled by its TO-247AD package and 1.5 °C/W RθJC. It sustains 300A non-repetitive surge current (8.3 ms half-sine) and maintains <1000 µA reverse leakage at 25°C and rated VRRM.
Designed for high-efficiency switching applications, it delivers stable performance across -55°C to +150°C junction temperature range, with matte tin-plated leads compliant to J-STD-002 and JESD 201 Class 2 whisker testing.
Key Specifications

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-30CPH03-M3 | Same 30V VRRM, 30A IF, TO-247 package; VF = 0.52V @ 15A but TJ max = 175°C and no AEC-Q101 qualification. | Preferred in high-temp industrial UPS where automotive qualification is unnecessary. | Select when higher junction temperature margin is prioritized over automotive compliance. |
| ON Semiconductor MBR3030CT | 30V, 30A dual common-cathode Schottky; VF = 0.57V @ 15A, TO-220AC package, no AEC-Q101, RθJC = 2.5 °C/W. | Suitable for cost-sensitive consumer adapters with lower thermal demands. | Choose only if board space permits larger footprint and thermal performance requirements are relaxed. |
Compared with VS-30CPH03-M3 and MBR3030CT, the SR3030PTH uniquely combines AEC-Q101 qualification, 1.5 °C/W thermal resistance, and 0.55V forward drop-making it optimal for space-constrained, thermally demanding automotive and industrial rectification where reliability and efficiency are co-prioritized.

FAQ
What is the maximum junction temperature rating for SR3030PTH?
The SR3030PTH has a maximum junction temperature (TJ) rating of +150°C, verified per its absolute maximum ratings table. This allows reliable operation in under-hood automotive environments and high-ambient industrial settings without mandatory derating below 30A continuous current, provided thermal design meets RθJC = 1.5 °C/W and heatsink interface requirements. The SR3030PTH datasheet specifies this limit applies across its full operating voltage range.
Is SR3030PTH pin-compatible with other parts in the SR30xxPT family?
Yes, all SR30xxPT and SR30xxPTH variants-including SR3030PTH-share identical TO-247AD (TO-3P) mechanical outline, pin assignment (anode/cathode/tab), and mounting dimensions. Voltage rating differences (e.g., SR3020PTH vs. SR30150PTH) do not affect physical compatibility, enabling layout reuse across the family when thermal and electrical margins permit.
Does SR3030PTH require a heatsink in typical 30A operation?
Yes, the SR3030PTH requires an external heatsink for sustained 30A operation. With RθJC = 1.5 °C/W and typical VF = 0.55V, power dissipation exceeds 16.5W-generating ~25°C rise above case temperature even before ambient contribution. A properly sized heatsink maintaining case temperature ≤85°C ensures junction stays within the +150°C limit. The SR3030PTH thermal curves confirm derating begins above 80°C case temperature.
What does the 'H' suffix in SR3030PTH signify?
The 'H' suffix in SR3030PTH explicitly denotes AEC-Q101 qualification, as confirmed in the ordering information section of the Taiwan Semiconductor datasheet. This means the SR3030PTH has undergone stress testing for automotive-grade reliability-including temperature cycling, humidity bias, and ESD-meeting the full AEC-Q101 standard for discrete semiconductors. Non-H variants (e.g., SR3030PT) lack this qualification.
How does SR3030PTH compare to silicon PN rectifiers in the same package?
The SR3030PTH offers significantly lower forward voltage (0.55V vs. ≥0.9V for comparable 30A PN rectifiers), resulting in ~40% lower conduction loss at 30A. Its Schottky architecture also eliminates minority-carrier storage delay, enabling faster switching and reduced EMI in high-frequency SMPS. However, the SR3030PTH exhibits higher reverse leakage (≤1000 µA) than PN types, making it less suitable for ultra-low-power standby circuits where leakage dominates loss.
