Product details
Overview
SR16100PT from Taiwan Semiconductor is a 16A, 100V Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 0.90 V forward voltage at 8 A and 25°C, 200 A surge capability, 3°C/W junction-to-case thermal resistance, and AEC-Q101 qualification option. It serves as a high-efficiency output rectifier in DC/DC converters and industrial SMPS.
For engineers reviewing the SR16100PT datasheet, SR16100PT pinout, SR16100PT application, or SR16100PT equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, low VF at high IF, TJ max of 150°C, dual-die construction, and UL recognition under file E-326243.
Technical Context
This Schottky rectifier uses dual-die configuration in a single TO-247AD package to support high-current, low-loss operation. Its guard ring structure provides overvoltage protection, and matte tin-plated leads meet J-STD-002 solderability with JESD 201 Class 2 whisker resistance.
The device operates across -55°C to +150°C junction temperature range, delivers 5 µA max reverse current at 100 V and 125°C, and maintains thermal performance via 3°C/W RθJC, enabling compact heatsink designs in space-constrained power stages.
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-16CTH10-M3 | Same 100 V VRRM, 16 A IF, TO-247AC package; VF = 0.82 V @ 8 A, but no AEC-Q101 option | Lacks automotive qualification; suitable for commercial/industrial only | Prefer when lower VF is critical and automotive compliance is not required |
| ON Semiconductor MUR1610CT | 100 V, 16 A, TO-220AB package; ultrafast recovery (75 ns), not Schottky; VF ≈ 1.25 V | Higher conduction loss, slower switching; used where reverse recovery noise must be minimized | Select only if reverse recovery EMI is dominant concern over efficiency |
Compared with VS-16CTH10-M3 and MUR1610CT, SR16100PT offers the only combination of 100 V/16 A Schottky performance, AEC-Q101 availability, and TO-247AD thermal robustness-making it optimal for thermally demanding, automotive-qualified, or high-reliability industrial power supplies.

FAQ
What is the maximum junction temperature rating for SR16100PT?
The SR16100PT has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments such as enclosed industrial enclosures or automotive under-hood locations when paired with appropriate heatsinking. The SR16100PT's thermal resistance of 3°C/W further supports reliable thermal management at this limit.
Is SR16100PT pin-compatible with other parts in the SR16xPT family?
Yes, all SR16xPT devices-including SR16100PT-share identical TO-247AD (TO-3P) mechanical footprint, pinout, and terminal assignment. Voltage variants (20 V to 150 V) differ only in internal die construction; PCB layout and mounting remain unchanged across the family, simplifying BOM consolidation and design reuse.
Does SR16100PT have AEC-Q101 qualification?
The SR16100PT itself is not automatically AEC-Q101 qualified; however, the AEC-Q101-qualified version is offered as SR16100PTH (with 'H' suffix). This variant undergoes full stress testing per AEC-Q101 Rev D, including HTGB, TCT, and ESD, and carries the same electrical specs and TO-247AD package as SR16100PT.
What is the typical forward voltage of SR16100PT at 16 A?
The datasheet specifies VF = 0.90 V at 8 A and 25°C; at 16 A, VF rises to approximately 1.05–1.10 V (extrapolated from typical forward characteristics curve Fig.4). This remains significantly lower than silicon rectifiers, preserving efficiency in high-current output stages of the SR16100PT-based design.
How does the guard ring in SR16100PT improve reliability?
The guard ring in SR16100PT mitigates edge breakdown under high dV/dt or transient overvoltage conditions by distributing electric field stress away from the active junction periphery. This structural feature enhances ruggedness in SMPS applications with fast-switching MOSFETs and improves long-term reliability during line surges or load dump events in the SR16100PT's operational envelope.
