Taiwan Semiconductor Corporation SRA16100 C0G

Overview

SRA16100 from Taiwan Semiconductor is a 16A, 100V Schottky barrier rectifier in TO-220AC package, designed for high-efficiency DC/DC conversion with low forward voltage (0.92 V at 16 A, 25°C) and low reverse leakage (100 µA at 100 V, 25°C). It delivers high surge current capability (200 A, 8.3 ms half-sine) and operates up to 150°C junction temperature.

For engineers reviewing the SRA16100 datasheet, SRA16100 pinout, SRA16100 application, or SRA16100 equivalent, key selection factors include its 100 V repetitive peak reverse voltage, 5 °C/W junction-to-case thermal resistance, AEC-Q101 qualification option (SRA16100H), and suitability for automotive-grade power supplies requiring robust surge handling and low conduction loss.

Technical Context

The SRA16100 uses a single-die Schottky structure with integrated guard ring for overvoltage protection, enabling stable operation under transient conditions. Its VF–IF curve shows minimal voltage rise across 0–16 A at 25°C and maintains <0.92 V even at TJ = 125°C per characterization data.

Thermal performance is defined by R_θJC = 5 °C/W, supporting high-power dissipation when mounted on heatsinks. Reverse leakage remains tightly controlled-100 µA at 25°C and 5 mA at 125°C-ensuring reliability in elevated ambient environments typical of automotive and industrial converters.

FAQ

What is the maximum junction temperature rating for the SRA16100?

The SRA16100 has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table in the official datasheet. This allows reliable operation in high-ambient environments such as engine compartments or sealed industrial enclosures. Derating curves confirm usable current capacity down to 125°C case temperature, and the device maintains specified electrical parameters within this full range. The SRA16100 must be thermally managed using its TO-220AC metal tab to avoid exceeding T_J = 150°C.

Is the SRA16100 pin-compatible with other parts in the SRA16xx series?

Yes-the SRA16100 shares identical TO-220AC mechanical footprint, lead pitch, and pinout (anode–cathode–tab) with all members of the SRA1620–SRA16100 family. All variants use the same single-die configuration and mounting torque specification (≤0.56 N·m). This enables direct board-level substitution across voltage grades without layout changes, provided system-level V_RRM, V_F, and thermal constraints are validated for the selected variant.

Does the SRA16100 meet automotive reliability standards?

The base SRA16100 is not AEC-Q101 qualified, but the SRA16100H variant is explicitly certified to AEC-Q101. Per ordering information in the datasheet, "H" suffix denotes qualification including stress testing for temperature cycling, humidity bias, and high-temperature operating life. Designers targeting automotive applications must specify SRA16100H-not SRA16100-to ensure compliance. Both share identical electrical specs and package dimensions.

What is the forward voltage drop of the SRA16100 at full rated current?

The SRA16100 exhibits a typical forward voltage (V_F) of 0.92 V at I_F = 16 A and T_J = 25°C, as confirmed in the Electrical Specifications table. At elevated junction temperatures (e.g., 125°C), V_F decreases slightly due to Schottky physics, remaining below 0.90 V. This value was measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects, and represents the actual conduction loss used in efficiency calculations for the SRA16100.

How does the guard ring feature improve reliability of the SRA16100?

The guard ring in the SRA16100 is a diffusion-based structural element surrounding the active Schottky junction, designed to suppress edge electric field crowding during reverse-biased transients. It prevents premature avalanche breakdown at the die periphery, thereby increasing the device's ability to withstand repetitive voltage spikes and load-dump events common in automotive and industrial power systems. This feature directly contributes to the SRA16100's robustness without requiring external snubbers or derating.
