Product details
Overview
SR005HR0G from Taiwan Semiconductor is a 0.5A, 50V AEC-Q101-qualified Schottky barrier rectifier in DO-204AL (DO-41) package, featuring 0.70V max forward voltage at 0.5A and 5 mA reverse current at 100°C, used in automotive-grade DC-DC converters and SMPS secondary-side rectification.
For engineers reviewing the SR005HR0G datasheet, SR005HR0G pinout, SR005HR0G application, or SR005HR0G equivalent, key selection criteria include its AEC-Q101 qualification, 50V VRRM, 30A IFSM, junction-to-ambient thermal resistance of 50°C/W, and DO-41 mechanical compatibility with legacy through-hole power designs.
Technical Context
This discrete Schottky diode operates as a unidirectional, single-die rectifier with guard ring structure for overvoltage protection and pure tin-plated leads compliant with J-STD-002 solderability. Its 80 pF junction capacitance at 1 MHz/4 V enables moderate-frequency switching performance.
The device supports continuous operation up to 150°C junction temperature and delivers stable reverse leakage (≤5 mA at 100°C) across its rated 50V VRRM, making it suitable for thermally constrained automotive cabin modules and industrial adapters where efficiency and reliability are co-prioritized.
Key Specifications

| VF (max) | 0.70 V @ 0.5A, 25°C - Low conduction loss enabling >92% efficiency in 5V/0.5A buck-derived outputs |
| IFSM | 30 A - Non-repetitive surge rating; withstands inrush during hot-plug or load dump events |
| TJ (max) | 150 °C - Extended junction temperature limit allows operation in under-hood environments without derating |
| CJ | 80 pF @ 1 MHz, 4 V - Limits high-frequency displacement current in <1 MHz switching topologies |
| RθJA | 50 °C/W - Enables 0.5W dissipation with ≤25°C rise above ambient on standard FR-4 PCB with minimal copper area |
Pinout & Package
Package: DO-204AL (DO-41), axial leaded, epoxy-molded case with cathode band polarity marking; RoHS-compliant, halogen-free, UL 94V-0 rated compound; 0.330g typical weight.

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-50SQ030 | 30V VRRM, 0.42V VF max @ 0.5A, TO-277 surface-mount package | Lower voltage rating; requires PCB redesign for SMT placement and reflow profile | Preferred where board space is constrained and 30V blocking suffices |
| ON Semiconductor SB0550 | 50V VRRM, 0.55V VF max @ 0.5A, DO-41 package, no AEC-Q101 qualification | Lacks automotive qualification; higher forward drop than SR005HR0G at elevated temperatures | Suitable for cost-sensitive industrial adapters without automotive certification needs |
Compared with VS-50SQ030 and SB0550, SR005HR0G uniquely combines AEC-Q101 qualification, 50V blocking, DO-41 through-hole compatibility, and 0.70V VF optimized for thermal stability-making it the only choice for drop-in replacement in qualified automotive harness assemblies.

FAQ
What is the peak repetitive reverse voltage rating for SR005HR0G?
The SR005HR0G has a peak repetitive reverse voltage (VRRM) rating of 50 V. This value is fixed per the "005" designation in the part number and confirmed in the Absolute Maximum Ratings table. It defines the maximum reverse-biased voltage the device can block continuously without breakdown under normal operating conditions.
Is SR005HR0G qualified for automotive applications?
Yes, SR005HR0G is AEC-Q101 qualified, as indicated by the "H" suffix in the ordering code. This qualification covers stress testing for temperature cycling, humidity bias, mechanical shock, and other automotive-specific reliability requirements, making SR005HR0G suitable for use in engine control, body electronics, and ADAS subsystems.
What does the "R0G" suffix mean in SR005HR0G?
The "R0G" suffix in SR005HR0G indicates green compound (halogen-free) molding material per IEC 61249-2-21, and "R0" denotes tape-and-reel packaging with 5,000 units per reel. The "H" confirms AEC-Q101 qualification, while "005" specifies the 50V VRRM rating - all defined in the official Taiwan Semiconductor ordering information table.
What is the maximum forward voltage drop of SR005HR0G at rated current?
The maximum forward voltage drop (VF) of SR005HR0G is 0.70 V at IF = 0.5 A and TJ = 25°C, per the Electrical Specifications table. At elevated junction temperatures (e.g., 100°C), VF decreases slightly, but the 0.70 V value remains the design-limiting parameter for worst-case conduction loss calculation.
Can SR005HR0G replace SR005H in a design?
Yes, SR005HR0G is functionally identical to SR005H, with the addition of halogen-free (G) compound and tape-and-reel (R0) packaging. Both share identical electrical specifications, AEC-Q101 qualification, DO-41 package, and thermal performance. No circuit or layout changes are required when migrating from SR005H to SR005HR0G.
