Product details
Overview
SR005 R0G from Taiwan Semiconductor is a 0.5A, 50V Schottky barrier rectifier in DO-204AL (DO-41) package, featuring low forward voltage drop (VF ≤ 0.70 V at IF = 0.5 A, TJ = 25°C), high surge current capability (IFSM = 30 A), junction temperature rating up to +150°C, and RoHS/halogen-free compliance. It serves as a primary output rectifier in compact DC-DC converters.
For engineers reviewing the SR005 R0G datasheet, SR005 R0G pinout, SR005 R0G application, or SR005 R0G equivalent, key selection criteria include its 50 V repetitive peak reverse voltage (VRRM), 80 pF junction capacitance at 1 MHz/4 V, 5 mA reverse leakage at TJ = 100°C, thermal resistance of 50°C/W, and AEC-Q101 qualification status indicated by 'H' suffix variants.
Technical Context
This discrete Schottky diode operates with unidirectional conduction and zero minority-carrier storage, enabling fast switching and minimal reverse recovery loss. Its guard ring structure enhances ruggedness against transient overvoltage events, while pure tin-plated leads ensure J-STD-002 solderability and JESD201 Class 2 whisker resistance.
The device is rated for continuous forward current of 0.5 A at TA = 75°C (derated from 0.5 A at TA = 25°C), with thermal performance defined by RθJA = 50°C/W. Reverse leakage remains below 5 mA up to TJ = 100°C, supporting stable operation in thermally constrained power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse voltage the diode blocks without breakdown; defines usable input/output voltage range in SMPS designs. |
| IF | 0.5 A - Continuous average forward current rating at TA = 25°C; derates to ~0.35 A at TA = 75°C per curve data. |
| VF | ≤ 0.70 V - Forward voltage at 0.5 A and 25°C; directly determines conduction loss (0.35 W typical) and efficiency in low-voltage outputs. |
| IFSM | 30 A - Non-repetitive surge current (8.3 ms half-sine); supports robustness against startup/load-dump transients. |
| TJ max | +150°C - Maximum junction temperature; enables operation in high-ambient industrial or automotive under-hood environments. |
| CJ | 80 pF - Junction capacitance at 1 MHz / 4 V; impacts high-frequency switching noise and EMI filter design in >100 kHz converters. |
| IR @ TJ=100°C | 5 mA - Reverse leakage at elevated temperature; critical for standby power budgeting and thermal runaway avoidance. |
Pinout & Package
Package: DO-204AL (DO-41), axial leaded, epoxy-molded case meeting UL 94V-0. Cathode indicated by band; leads are pure tin-plated, solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); polarity must match layout to avoid catastrophic failure. |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to output rail or ground return; band orientation must be verified during automated optical inspection (AOI) and manual assembly. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Improves edge termination reliability and withstands transient overvoltage spikes common in automotive load-dump conditions. |
| AEC-Q101 qualification (H-suffix variants) | Validated for automotive-grade stress testing including temperature cycling, HTRB, and ESD; R0G suffix indicates standard industrial grade. |
| Low VF (≤0.70 V) | Reduces conduction loss by ~25% vs. comparable 50 V silicon rectifiers, improving efficiency in 3.3–12 V output rails. |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU; required for export to EU, Japan, and China electronics markets. |
| Junction-to-ambient RθJA = 50°C/W | Enables thermal design with minimal heatsinking in PCB-mounted applications; requires ≥ 1 cm² copper pour for full 0.5 A rating at TA = 75°C. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SS15 | Same DO-41 package, 50 V VRRM, 1.5 A IF rating, VF ≈ 0.52 V at 1.5 A - higher current capacity but larger conduction loss at 0.5 A due to different doping profile. | Preferred where future current scaling or parallel use is anticipated; less optimal for strict 0.5 A footprint-constrained designs. | Select SS15 only if board layout accommodates same footprint but higher thermal mass and system requires >0.5 A headroom. |
| ON Semiconductor SB0550 | DO-41, 50 V VRRM, 0.5 A IF, VF = 0.55 V max at 0.5 A - lower VF than SR005 R0G, but IR = 100 µA at 25°C vs. 500 µA for SR005 R0G; no AEC-Q101 option available. | Better for ultra-low standby power designs; unsuitable for automotive qualification-critical programs. | Choose SB0550 for consumer adapters prioritizing light-load efficiency; retain SR005 R0G for industrial temp range or where AEC-Q101 traceability is needed via H-suffix variants. |
Compared with SS15 and SB0550, SR005 R0G offers balanced trade-offs: moderate VF (0.70 V), proven 150°C operation, and direct qualification path to AEC-Q101 via SR005H - making it optimal for cost-sensitive industrial and Tier-2 automotive subsystems requiring validated reliability without over-spec'ing current or efficiency.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for SR005 R0G?
The SR005 R0G has a VRRM of 50 V, meaning it reliably blocks up to 50 V of reverse voltage in repetitive operation. This value is fixed per the SR005 designation in the SR002–SR010 family and is confirmed in the Absolute Maximum Ratings table on page 2 of the H2104 datasheet. Exceeding this voltage risks avalanche breakdown and permanent damage to the SR005 R0G.
Does SR005 R0G meet AEC-Q101 automotive qualification standards?
No, SR005 R0G does not carry AEC-Q101 qualification. The 'R0G' suffix denotes standard industrial grade with green compound and tape-and-reel packaging. AEC-Q101 qualified versions are marked with an 'H' suffix (e.g., SR005H). While SR005 R0G shares the same die and package as SR005H, only the H-suffix variant undergoes the full stress test sequence required for automotive use.
What is the forward voltage (VF) specification for SR005 R0G at 0.5 A and 25°C?
The SR005 R0G has a maximum forward voltage of 0.70 V at IF = 0.5 A and TJ = 25°C, as specified in the Electrical Specifications table on page 2 of the H2104 datasheet. This value is typical for 50 V Schottky rectifiers and directly determines conduction loss - resulting in ~0.35 W dissipation at full rated current under nominal conditions.
Can SR005 R0G be used in surface-mount designs?
No, SR005 R0G is packaged in DO-204AL (DO-41), an axial-leaded through-hole package. It is not compatible with standard SMT reflow processes. For surface-mount alternatives, consider TSC's SOD-123 or SMA packages (e.g., SR005L), or equivalent Schottky diodes like Diodes Inc. AP1505-50W (SMA) - but note these differ in thermal performance and pinout.
What is the junction-to-ambient thermal resistance (RθJA) of SR005 R0G?
The SR005 R0G has a typical junction-to-ambient thermal resistance of 50°C/W, measured under standard JEDEC test conditions (single device on 1-inch² FR-4 board with 2 oz copper). This value assumes no added heatsinking and defines the temperature rise above ambient at a given power dissipation - e.g., 0.35 W loss yields ~17.5°C rise above TA.
