Product details
Overview
SR209HR0G from Taiwan Semiconductor is a 2 A, 90 V AEC-Q101-qualified Schottky barrier rectifier in DO-204AC (DO-15) package, featuring 0.85 V forward voltage at 2 A and 100 µA reverse leakage at 25°C, used in automotive-grade DC-DC converters and SMPS secondary-side rectification.
For engineers reviewing the SR209HR0G datasheet, SR209HR0G pinout, SR209HR0G application, or SR209HR0G equivalent, this page delivers verified electrical specs, thermal performance data, mechanical dimensions, and direct AEC-Q101 qualification status for automotive power design validation.
Technical Context
This Schottky rectifier uses a single-die construction with guard ring overvoltage protection and pure tin-plated leads compliant with J-STD-002 solderability. Its 10,000 V/µs critical dv/dt rating supports fast-switching topologies without parasitic turn-on.
Thermal design is enabled by RθJL = 21.7°C/W and RθJA = 75.0°C/W, with maximum junction temperature rated to +150°C - enabling operation in under-hood automotive environments where ambient exceeds 105°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - blocks up to 90 V repetitive reverse voltage, suitable for 48 V system-derived rail designs |
| IF | 2 A continuous - supports compact 20–30 W DC-DC output stages without forced air cooling |
| VF @ 2 A, 25°C | 0.85 V - reduces conduction loss to ≤1.7 W per device, improving efficiency vs. Si diodes |
| IR @ 90 V, 25°C | 100 µA - ensures low standby power loss in always-on automotive modules |
| IFSM (8.3 ms) | 50 A - withstands cold-crank surge events in 12 V vehicle systems |
| TJ max | +150°C - enables placement near heat-generating components in engine control units |
| RθJL | 21.7°C/W - allows direct PCB copper pour thermal coupling to improve power derating margin |

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-2EY90-M3/54 | Same DO-15 package, 2 A/90 V, VF = 0.87 V @ 2 A, IR = 150 µA @ 25°C | Slightly higher leakage limits use in ultra-low-power standby circuits | Preferred when sourcing from Vishay-authorized channels; identical footprint but requires layout verification for thermal pad clearance |
| ON Semiconductor SB290 | DO-15, 2 A/90 V, VF = 0.82 V @ 2 A, IR = 200 µA @ 25°C, no AEC-Q101 listing | Lacks automotive qualification; not approved for ECU or ADAS use | Select only for cost-sensitive industrial or consumer applications where AEC-Q101 is not mandated |

FAQ
What is the peak repetitive reverse voltage rating of SR209HR0G?
The SR209HR0G has a peak repetitive reverse voltage (VRRM) rating of 90 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version L2105), and defines the maximum reverse-biased voltage the device can block continuously without breakdown under normal operating conditions.
Is SR209HR0G qualified to AEC-Q101 standards?
Yes, SR209HR0G is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and confirmed in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and high-temperature reverse bias - validating suitability for automotive under-hood applications.
What is the forward voltage of SR209HR0G at 2 A and 25°C?
The forward voltage (VF) of SR209HR0G is 0.85 V at 2 A and 25°C, per the Electrical Specifications table in the official datasheet. This value is measured under pulsed conditions (PW = 0.3 ms) and represents typical conduction loss behavior in real-world switching power supplies.
Does SR209HR0G have halogen-free construction?
Yes, SR209HR0G is halogen-free in accordance with IEC 61249-2-21, as stated in the FEATURES section of the Taiwan Semiconductor datasheet. This ensures compliance with automotive OEM material declarations and supports environmentally responsible end-of-life processing.
What is the maximum junction temperature for SR209HR0G?
The maximum junction temperature (TJ) for SR209HR0G is +150°C, as specified in the Absolute Maximum Ratings table. This rating applies across the full operating range and enables deployment in high-ambient environments such as engine compartments or sealed industrial enclosures where passive cooling is limited.
