Product details
Overview
SRS1660H from Taiwan Semiconductor is a 16A, 60V AEC-Q101-qualified Schottky barrier rectifier in TO-263AB (D2PAK) package, featuring 0.70V forward voltage at 8A/25°C, 150A surge current capability, and dual-die construction for high-efficiency DC/DC conversion and freewheeling applications in automotive lighting and power systems.
For engineers reviewing the SRS1660H datasheet, SRS1660H pinout, SRS1660H application, or SRS1660H equivalent, key selection criteria include its 60V repetitive peak reverse voltage, 10mA reverse leakage at 100°C, junction-to-case thermal resistance of 2°C/W, AEC-Q101 qualification, and TO-263AB mechanical compatibility with automated SMT placement.
Technical Context
The SRS1660H integrates two independent Schottky die in a single TO-263AB (D2PAK) thermally optimized package, enabling dual-path rectification or parallel operation. Its guard ring structure provides overvoltage protection, while matte tin-plated leads meet J-STD-002 solderability and JESD 201 Class 2 whisker resistance requirements.
Designed for high-frequency switching environments, the device operates with a maximum junction temperature of +150°C and supports stable performance across -55°C to +150°C storage range. Its 2°C/W RθJC enables efficient heat transfer to the PCB copper plane under 16A continuous forward current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in reverse-biased freewheeling or reverse battery protection circuits |
| IF | 16 A - Continuous forward current rating; determines minimum trace width and heatsinking for sustained conduction in DC/DC converters |
| IFSM | 150 A - Non-repetitive surge current (8.3ms half-sine); supports robustness against inductive kickback in motor drive or solenoid control |
| VF | 0.70 V @ 8A, 25°C - Low forward drop reduces conduction loss and improves system efficiency in low-voltage, high-current paths |
| IR | 500 µA @ 60V, 25°C; 10 mA @ 60V, 100°C - Reverse leakage directly impacts standby power loss and thermal runaway risk in high-temp automotive modules |
| RθJC | 2 °C/W - Junction-to-case thermal resistance; enables precise thermal modeling when mounting to heatsinked PCBs or metal-core substrates |
Pinout & Package
TO-263AB (D2PAK) surface-mount package with three terminals: Anode 1, Cathode (common), Anode 2. The case serves as the cathode connection, supporting dual-anode configuration for independent or paralleled operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab / Case | Cathode (common) | Electrically connected to internal cathode metallization; must be soldered to large copper pour for thermal and electrical conduction |
| Lead 1 | Anode 1 | First Schottky die anode; enables independent control or sensing of first diode path |
| Lead 2 | Anode 2 | Second Schottky die anode; allows dual-output rectification or redundancy without external splitting |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
| Guard ring structure | Enhances edge termination robustness against transient overvoltage events without requiring external snubbers |
| Dual-die configuration | Enables space-efficient dual-path rectification or current sharing in compact 12V/24V automotive power rails |
| Moisture sensitivity level 1 | Eliminates bake requirement prior to reflow; compatible with standard SMT assembly lines without dry-pack handling |

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-16CTQ060PBF | Single-die 16A/60V Schottky; no dual-anode configuration; RθJC = 2.5°C/W | Lacks dual-anode flexibility; requires external parallel diodes for redundant paths | Preferred where board space permits discrete layout and dual functionality is unnecessary |
| ON Semiconductor MBR1660CT | 16A/60V dual common-cathode Schottky; TO-220AC package; VF = 0.72V @ 8A | Through-hole mounting only; higher thermal resistance (RθJC = 3.0°C/W); not AEC-Q101 qualified | Acceptable for industrial non-automotive use where AEC-Q101 compliance is not required |
Compared with VS-16CTQ060PBF and MBR1660CT, the SRS1660H uniquely combines AEC-Q101 qualification, dual-anode TO-263AB packaging, and 2°C/W thermal resistance-making it optimal for space-constrained, high-reliability automotive power stages requiring integrated redundancy or layout simplification.

FAQ
What is the maximum junction temperature rating for the SRS1660H?
The SRS1660H has a maximum junction temperature (TJ) rating of +150°C, validated per AEC-Q101 stress testing. This allows reliable operation in under-hood automotive environments where ambient temperatures exceed 105°C, provided thermal design maintains junction temperature below this limit using the specified 2°C/W RθJC and adequate PCB copper area. The SRS1660H datasheet confirms this rating applies across its full operating voltage range.
Is the SRS1660H pin-compatible with other parts in the SRS16xxH family?
Yes, all SRS16xxH devices-including SRS1660H-share identical TO-263AB (D2PAK) package dimensions, pinout, and terminal configuration. The marking code "SRS1660" on the device surface identifies the 60V variant, but mechanical and solder footprint compatibility is maintained across the entire SRS1620H–SRS16100H series. This enables voltage-scaling flexibility without PCB redesign.
Does the SRS1660H require special handling for moisture sensitivity?
No, the SRS1660H is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and processed directly in standard reflow profiles without baking or dry-pack requirements. This simplifies manufacturing logistics and eliminates yield loss from moisture-related popcorning during SMT assembly of the SRS1660H.
What is the reverse leakage current specification for the SRS1660H at elevated temperature?
At 60V reverse bias and 100°C junction temperature, the SRS1660H exhibits a maximum reverse leakage current (IR) of 10 mA, as specified in the Electrical Specifications table. This value is critical for evaluating standby power loss in always-on automotive modules; the SRS1660H's 10 mA rating ensures predictable thermal behavior even in high-temperature cabin or engine bay locations.
How does the guard ring feature improve reliability of the SRS1660H in automotive applications?
The guard ring in the SRS1660H enhances edge termination robustness against transient overvoltage events such as load dump or inductive switching spikes. By distributing electric field stress away from the active junction periphery, it prevents premature avalanche breakdown and increases long-term reliability in harsh automotive environments-without requiring external snubber networks. This structural feature is integral to the SRS1660H die design and verified in AEC-Q101 testing.
