Product details
Overview
SR30100PT from Taiwan Semiconductor is a 30A, 100V Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring dual-die construction, 0.90V max forward voltage at 15A/25°C, 500µA max reverse leakage at rated VR and 300A surge capability - deployed in high-efficiency DC-DC converters and industrial SMPS.
For engineers reviewing the SR30100PT datasheet, SR30100PT pinout, SR30100PT application, or SR30100PT equivalent, key selection criteria include VRRM = 100V, IF = 30A continuous, RθJC = 1.5°C/W, TJ max = 150°C, and AEC-Q101 qualification availability - critical for automotive-grade power conversion designs requiring low conduction loss and robust thermal performance.
Technical Context
The SR30100PT implements a dual-die Schottky architecture optimized for unidirectional high-current rectification in switching topologies. Its 100V repetitive peak reverse voltage and 0.90V typical forward voltage at 15A enable reduced conduction losses versus silicon diodes in 48V–60V bus applications.
Thermally, it delivers 1.5°C/W junction-to-case resistance with TO-247AD mounting, supporting sustained 30A operation under forced-air or heatsink-cooled conditions. Reverse leakage remains ≤500µA at 25°C and ≤10mA at 100°C, ensuring stable blocking in high-temperature environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage the device blocks without breakdown; defines usable input voltage range in buck or flyback secondary-side rectification. |
| IF | 30 A - Continuous forward current rating at case temperature ≤100°C; supports high-power adapter and server PSU output stages. |
| IFSM | 300 A - Non-repetitive surge current (8.3ms half-sine); withstands inrush and transient overloads in industrial power supplies. |
| VF | 0.90 V max @ 15A, 25°C - Low forward drop reduces conduction loss and improves system efficiency vs. standard PN diodes. |
| RθJC | 1.5 °C/W - Thermal resistance from junction to case; enables predictable heatsink sizing for thermal management in enclosed enclosures. |
| TJ max | 150 °C - Maximum allowable junction temperature; allows operation in under-hood automotive or high-ambient industrial environments. |
| IR | 500 µA max @ 100V, 25°C - Low reverse leakage preserves efficiency and stability in high-impedance bias networks and standby circuits. |

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-30CPH10-M3 | Same 100V VRRM, 30A IF, TO-247AC package; VF = 0.82V typ @ 15A but no AEC-Q101 option. | Preferred for commercial/industrial use where automotive qualification is unnecessary; slightly lower VF improves light-load efficiency. | Select when AEC-Q101 is not required and sub-0.85V forward drop is prioritized. |
| ON Semiconductor MBR30100CT | 100V, 30A dual common-cathode Schottky; TO-220AB package; VF = 0.92V max; RθJC = 2.0°C/W; no AEC-Q101. | Suitable for cost-sensitive consumer applications; limited thermal performance vs. TO-247AD; not rated for >125°C junction. | Choose for space-constrained PCBs where TO-220 footprint suffices and ambient temperatures remain <85°C. |
Compared with VS-30CPH10-M3 and MBR30100CT, the SR30100PT offers superior thermal resistance (1.5°C/W), AEC-Q101 qualification path, and guard ring protection - making it optimal for automotive and high-reliability industrial deployments where thermal margin and transient robustness are design-critical.

FAQ
What is the maximum junction temperature rating for the SR30100PT?
The SR30100PT has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows reliable operation in high-ambient environments such as under-hood automotive locations or sealed industrial enclosures. The SR30100PT maintains specified electrical performance up to this limit when thermal design respects the 1.5°C/W RθJC and appropriate heatsinking is applied.
Is the SR30100PT pin-compatible with other SR30xxPT series devices?
Yes - all SR30xxPT devices, including SR30100PT, share identical TO-247AD (TO-3P) mechanical outline, pin assignment (anode/cathode/tab), and mounting dimensions. Voltage variants (20V–150V) differ only in internal die construction; PCB layout and thermal interface design can be reused across the family without modification.
Does the SR30100PT have AEC-Q101 qualification?
The SR30100PT is available in an AEC-Q101-qualified version denoted by the "H" suffix (e.g., SR30100PTH). Standard SR30100PT is not automatically qualified; qualification applies only to parts ordered with the "H" suffix and documented in TSC's AEC-Q101 certificate. Always verify ordering code and datasheet revision before automotive use.
What is the forward voltage specification for the SR30100PT at 30A?
The SR30100PT datasheet specifies forward voltage (VF) at IF = 15A, not 30A. At 15A and 25°C, VF is ≤0.90V. Extrapolating to 30A requires derating: typical VF rises to ~1.05–1.15V depending on junction temperature. For 30A continuous operation, thermal design must ensure TJ stays ≤125°C to maintain reliability.
How does the guard ring feature improve reliability of the SR30100PT?
The guard ring in the SR30100PT mitigates electric field crowding at the semiconductor junction periphery, preventing localized avalanche and premature breakdown during voltage transients or line surges. This extends operational life in SMPS applications exposed to repetitive line spikes, especially in industrial mains-connected equipment where overvoltage immunity is critical to long-term field reliability.
