Product details
Overview
SRA1690HC0G from Taiwan Semiconductor is a 16A, 90V AEC-Q101-qualified Schottky barrier rectifier in TO-220AC package, featuring 0.92V forward voltage at 16A/25°C, 200A surge capability, and 5°C/W junction-to-case thermal resistance for high-efficiency power conversion in automotive-grade SMPS.
For engineers reviewing the SRA1690HC0G datasheet, SRA1690HC0G pinout, SRA1690HC0G application, or SRA1690HC0G equivalent, key selection criteria include its 90V repetitive peak reverse voltage, low IR of 100µA at 25°C, 150°C maximum junction temperature, AEC-Q101 qualification, and TO-220AC mechanical compatibility with standard heatsink mounting.
Technical Context
This discrete Schottky diode uses a single-die construction with guard ring overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its thermal design supports 5°C/W RθJC, enabling stable operation up to 150°C junction temperature under continuous 16A conduction.
Electrical behavior is defined by low VF (0.92V typ. @16A/25°C), tight IR control (100µA max @90V/25°C; 5mA max @90V/125°C), and robust IFSM rating of 200A (8.3ms half-sine), making it suitable for high-reliability DC-DC and adapter applications where efficiency and surge resilience are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 90V-rated power rails |
| IF | 16 A - Continuous forward current rating; determines minimum heatsink sizing for steady-state conduction |
| VF | 0.92 V (typ) @16A/25°C - Low conduction loss directly improves system efficiency and reduces thermal load |

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-16CTH09-M3 | Same 90V VRRM, 16A IF, TO-220AC, but VF = 0.87V (typ) @16A/25°C; no AEC-Q101 claim | Preferred for non-automotive industrial use where lower VF is prioritized over qualification | Select when AEC-Q101 is not required and sub-0.9V VF improves system efficiency targets |
| ON Semiconductor MUR1690CTG | 90V VRRM, 16A IF, TO-220AC, but ultrafast recovery (75ns) vs. Schottky; VF = 1.2V (typ); higher conduction loss | Suitable for higher-frequency flyback topologies where reverse recovery time matters more than VF | Choose only if circuit operates >100kHz and reverse recovery behavior dominates loss budget |
Compared with VS-16CTH09-M3 and MUR1690CTG, the SRA1690HC0G uniquely combines AEC-Q101 qualification, 0.92V VF, and 90V/16A rating in TO-220AC-making it optimal for automotive and high-reliability industrial rectification where qualification and thermal performance are mandatory.

FAQ
What is the maximum junction temperature rating for the SRA1690HC0G?
The SRA1690HC0G has a maximum junction temperature (TJ) rating of +150°C, verified per its AEC-Q101 qualification and absolute maximum ratings table. This allows operation in demanding automotive under-hood and industrial high-ambient environments. The SRA1690HC0G maintains specified electrical performance up to this limit when thermal design respects its 5°C/W RθJC and derating curves.
Is the SRA1690HC0G pin-compatible with other TO-220AC Schottky rectifiers?
Yes-the SRA1690HC0G uses standard TO-220AC mechanical dimensions and 3-terminal pinout (anode, cathode, cathode-connected tab), matching industry-standard footprints. However, electrical parameters like VF, IR, and thermal resistance differ across vendors; always verify layout compatibility and thermal interface requirements before substitution. The SRA1690HC0G itself is not marketed as a drop-in replacement for other part numbers.
Does the SRA1690HC0G meet halogen-free and RoHS requirements?
Yes-the SRA1690HC0G uses halogen-free molding compound compliant with IEC 61249-2-21 and is fully RoHS compliant. These environmental specifications are confirmed in the official Taiwan Semiconductor datasheet revision K2103 and apply to all units bearing the "C0G" suffix, including the SRA1690HC0G.
What is the forward voltage specification for the SRA1690HC0G at elevated temperature?
The SRA1690HC0G forward voltage increases with junction temperature: typical VF is 0.92V at 25°C and rises to approximately 0.78V at 125°C (per characteristic curve extrapolation). The datasheet does not specify VF at 125°C directly but confirms conduction remains stable within rated IF up to 150°C. Designers should reference Fig.4 (Typical Forward Characteristics) in the SRA1690HC0G datasheet for precise VF vs. TJ curves.
How is the "H" and "C0G" suffix interpreted in SRA1690HC0G?
In SRA1690HC0G, "H" denotes AEC-Q101 qualification per Taiwan Semiconductor's ordering nomenclature, while "C0G" indicates halogen-free compound and RoHS compliance. Together, they confirm the SRA1690HC0G meets automotive reliability and environmental standards. The base part SRA1690 lacks these suffixes and is not qualified or halogen-free.
