Product details
Overview
SR1630PTH from Taiwan Semiconductor is a 16A, 30V AEC-Q101 qualified Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 0.55V forward voltage at 8A/25°C, 200A surge capability, and junction-to-case thermal resistance of 3°C/W. It serves as a high-efficiency output rectifier in automotive-grade DC-DC converters and industrial SMPS.
For engineers reviewing the SR1630PTH datasheet, SR1630PTH pinout, SR1630PTH application, or SR1630PTH equivalent, key selection criteria include its AEC-Q101 qualification, low VF at rated current, dual-die construction for parallel operation, and UL Recognized status (E-326243) for safety-critical power systems.
Technical Context
This device implements a single-die Schottky structure optimized for low conduction loss and fast switching in unidirectional DC output stages. Its 30V VRRM rating targets 24V-input automotive and industrial DC-DC topologies where reverse recovery is eliminated and efficiency must exceed 92% at full load.
The TO-247AD package enables direct heatsink mounting with 1.13 N·m max torque, while matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements-critical for under-hood automotive reliability.
Key Specifications

| VRRM | 30 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for input/output voltage differential in buck-derived topologies |
| IF | 16 A - Continuous forward current rating at case temperature ≤125°C; defines steady-state power delivery capacity |
| IFSM | 200 A - Non-repetitive surge current for 8.3ms half-sine; supports cold-start inrush and transient overload without failure |
| VF @ 8A, 25°C | 0.55 V - Forward voltage drop per diode; determines conduction loss (P = IF × VF) and thermal rise in high-current paths |
| RθJC | 3 °C/W - Junction-to-case thermal resistance; enables accurate heatsink sizing for 125°C max junction operation |
| IR @ 30V, 25°C | 500 µA - Reverse leakage per diode; ensures minimal standby power loss in always-on systems |
| TJ max | 125 °C - Maximum operating junction temperature; validated for AEC-Q101 stress testing including temperature cycling and HTRB |

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-16CTH03-M3 | Same 30V VRRM, 16A IF, TO-247AC package; VF = 0.52V @ 8A but not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial/commercial only | Select when AEC-Q101 is not required and lowest VF is prioritized |
| ON Semiconductor MUR1630CTG | 30V VRRM, 16A IF, TO-220AB package; VF = 0.75V @ 8A; ultrafast recovery (not Schottky) | Higher VF increases conduction loss; TO-220 limits thermal performance vs. TO-247AD | Select only if TO-220 footprint is mandatory and 0.2V higher VF is acceptable |
Compared with VS-16CTH03-M3 and MUR1630CTG, SR1630PTH uniquely combines AEC-Q101 qualification, TO-247AD thermal performance, and 0.55V VF-making it the only option qualified for automotive under-hood DC-DC rectification without thermal or reliability compromise.

FAQ
What is the maximum junction temperature rating for SR1630PTH?
The SR1630PTH has a maximum junction temperature (TJ) rating of 125°C, verified under AEC-Q101 stress testing including high-temperature reverse bias (HTRB) and temperature cycling. This rating applies when the case temperature remains ≤125°C and thermal design maintains RθJC = 3°C/W to heatsink.
Is SR1630PTH pin-compatible with other parts in the SR16xPT family?
Yes, all SR16xPT and SR16xPTH parts-including SR1630PTH-share identical TO-247AD (TO-3P) mechanical outline, pin assignment (anode/cathode/tab), and mounting dimensions. Voltage variants differ only in internal die design, not package or terminal configuration.
Does SR1630PTH require a thermal pad or insulator when mounted to a heatsink?
Yes, the metal case (tab) of SR1630PTH is electrically connected to the cathode. When mounting to a conductive heatsink, an electrically isolating thermal pad or mica washer with thermal grease is required to prevent short circuits while maintaining thermal performance within the specified RθJC of 3°C/W.
What is the reverse leakage current specification for SR1630PTH at elevated temperature?
At TJ = 100°C and VR = 30V, SR1630PTH specifies a maximum reverse leakage current (IR) of 15 mA per diode. This value is measured under pulse conditions (PW = 30 ms) and reflects real-world behavior in high-ambient environments such as engine compartments.
How does the guard ring feature improve reliability in SR1630PTH?
The guard ring in SR1630PTH mitigates edge-related avalanche breakdown under high dv/dt or voltage transients. By controlling electric field distribution at the silicon periphery, it extends operational voltage margin and improves long-term stability in automotive load-dump and inductive switching environments.
