Product details
Overview
SRA1640HC0G from Taiwan Semiconductor is a 16A, 40V AEC-Q101-qualified Schottky barrier rectifier in TO-220AC package, featuring 0.55V forward voltage at 16A and 25°C, 200A surge capability, and guard ring overvoltage protection-used in automotive-grade DC/DC converters and industrial SMPS.
For engineers reviewing the SRA1640HC0G datasheet, SRA1640HC0G pinout, SRA1640HC0G application, or SRA1640HC0G equivalent, key selection criteria include VRRM = 40 V, IF = 16 A, TJ max = 150 °C, low VF for thermal efficiency, and AEC-Q101 qualification for automotive reliability validation.
Technical Context
This single-die Schottky rectifier uses platinum-silicide or similar barrier technology to achieve low forward voltage and fast switching with no minority-carrier recovery. Its guard ring structure enhances ruggedness against transient overvoltage events common in automotive load-dump conditions.
Thermal performance is defined by RθJC = 5 °C/W, enabling high-power dissipation when mounted on heatsinks per JESD201 Class 2 whisker-tested matte tin leads. The device operates across -55 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in 24V automotive systems with transients. |
| IF | 16 A - Continuous average forward current at case temperature ≤ 75 °C; supports high-density power conversion designs. |
| VF @ 16A, 25°C | 0.55 V - Low conduction loss reduces heat generation and improves system efficiency in high-current paths. |
| IFSM | 200 A - Non-repetitive surge rating (8.3 ms half-sine); withstands inrush and fault currents without failure. |
| TJ max | +150 °C - Extended junction temperature rating enables operation in under-hood automotive environments. |
| IR @ 40V, 25°C | 500 µA - Low leakage preserves efficiency in standby and light-load conditions. |
| RθJC | 5 °C/W - Junction-to-case thermal resistance; determines heatsink sizing for thermal management compliance. |
Pinout & Package
Package: TO-220AC - Three-terminal through-hole package with isolated tab, UL 94V-0 molding compound, matte tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current terminal | Connected to input rail (e.g., battery or bus); polarity marked on device body. |
| Cathode | Output current terminal | Connected to output filter capacitor or downstream converter stage; carries full load current. |
| Tab (Case) | Thermal & electrical connection to cathode | Electrically tied to cathode; must be insulated from chassis unless circuit design requires cathode grounding. |
Key Features

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-16CTH04-M3 | VRRM = 40 V, IF = 16 A, VF = 0.57 V @ 16A, TO-220AC, AEC-Q101 qualified | Same automotive qualification level; slightly higher VF increases conduction loss by ~3.6% at full load | Preferred where Vishay supply chain alignment or dual-sourcing is required |
| ON Semiconductor MUR1640CTG | VRRM = 40 V, IF = 16 A, VF = 0.75 V @ 16A, TO-220AC, not AEC-Q101 qualified | Lacks automotive qualification; suitable only for industrial/commercial use with lower reliability requirements | Select only for cost-sensitive non-automotive designs where 0.2 V higher VF is acceptable |
Compared with VS-16CTH04-M3 and MUR1640CTG, the SRA1640HC0G delivers the lowest VF among AEC-Q101-qualified 40V/16A Schottkys, enabling superior thermal performance in space-constrained automotive modules while maintaining full qualification compliance.

FAQ
What does the 'H' suffix in SRA1640HC0G indicate?
The 'H' in SRA1640HC0G denotes AEC-Q101 qualification, confirming that the SRA1640HC0G has passed stress testing for automotive applications including temperature cycling, humidity bias, and mechanical shock. This distinguishes it from standard industrial-grade variants like SRA1640C0G and validates its use in safety-critical vehicle subsystems.
Is the SRA1640HC0G pin-compatible with other TO-220AC Schottky rectifiers?
Yes, the SRA1640HC0G uses standard TO-220AC pinout (anode–cathode–tab), matching industry-standard footprints. However, thermal and electrical behavior-including VF, IR, and RθJC-must be verified against the specific design requirements before substitution, as the SRA1640HC0G's 0.55 V VF and 5 °C/W thermal resistance differ from many alternatives.
What is the maximum allowable case temperature for continuous operation of SRA1640HC0G?
The SRA1640HC0G supports continuous operation up to +150 °C junction temperature, but case temperature depends on mounting and heatsinking. With RθJC = 5 °C/W and 16A conduction, typical case temperature remains ≤ 75 °C under proper heatsink conditions-ensuring reliable long-term operation in automotive and industrial environments.
Does SRA1640HC0G require a heatsink in all applications?
A heatsink is recommended for SRA1640HC0G when operating above 8A average current or in ambient temperatures exceeding 50 °C. At full 16A load, junction temperature rises rapidly without thermal management; the SRA1640HC0G's 5 °C/W RθJC rating assumes direct metal-to-metal contact with an adequately sized heatsink per JEDEC standards.
How does the guard ring feature improve reliability of SRA1640HC0G?
The guard ring in SRA1640HC0G mitigates electric field crowding at the die edge, preventing premature avalanche breakdown during voltage transients such as load dump (ISO 7637-2 Pulse 5a). This structural enhancement directly contributes to the SRA1640HC0G's ability to sustain 40V reverse bias under harsh automotive conditions without degradation.
