Product details
Overview
SR510 A0G from Taiwan Semiconductor is a 5A, 100V Schottky barrier rectifier in DO-201AD package, featuring 0.85V max forward voltage at 5A and 100µA max reverse current at 25°C, optimized for high-efficiency DC/DC converters and industrial power adapters.
For engineers reviewing the SR510 A0G datasheet, SR510 A0G pinout, SR510 A0G application, or SR510 A0G equivalent, key selection criteria include its 100V VRRM, 120A IFSM surge rating, 6°C/W RθJC, AEC-Q101 qualification option (SR510H), and DO-201AD mechanical compatibility with standard through-hole reflow profiles.
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 dv/dt rating supports fast-switching topologies without parasitic turn-on.
Thermal performance is defined by 35°C/W RθJA (standard PCB layout) and 6°C/W RθJC, enabling sustained 5A operation up to 125°C junction temperature-critical for compact, convection-cooled SMPS designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage; sets safe operating limit in 48V–72V bus applications |
| IF | 5 A - Continuous forward current rating; defines minimum heatsinking requirement at full load |
| VF @ 5A, 25°C | ≤0.85 V - Low conduction loss; reduces power dissipation to ≤4.25W at rated current |
| IFSM | 120 A - Non-repetitive surge current (8.3ms half-sine); withstands cold-start inrush in AC/DC front-ends |
| RθJC | 6 °C/W - Junction-to-case thermal resistance; enables direct mounting to metal chassis for passive cooling |
| IR @ 100V, 25°C | ≤100 µA - Low leakage; preserves efficiency in standby mode and high-impedance feedback paths |
| TJ max | 125 °C - Maximum junction temperature; allows operation in sealed enclosures without forced air |
Pinout & Package
DO-201AD axial-leaded package with cathode band marking; 1.10g mass; UL 94V-0 molding compound; polarity indicated by single black band on cathode end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward current entry | Connected to input/bus side; requires trace width ≥1.5 mm for 5A continuous routing |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to output/load side; cathode band must align with PCB silkscreen polarity indicator |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Prevents edge breakdown at 100V reverse bias, improving long-term reliability in transient-prone industrial environments |
| Low VF (≤0.85V) | Reduces conduction loss by >30% vs. comparable 100V silicon rectifiers, directly increasing converter efficiency |
| AEC-Q101 qualified variant available | SR510H meets automotive-grade stress testing-enables use in under-hood DC/DC modules without derating |
| Pure tin plating | Ensures consistent solder wetting per J-STD-002; eliminates lead-free solder voiding risk in automated assembly |

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-50SQ100 | Same 100V VRRM, 5A IF, but TO-220AC package; higher RθJA (40°C/W) and no AEC-Q101 option | Requires heatsink mounting; unsuitable for space-constrained PCB layouts | Choose when board-level thermal management is impractical and chassis-mounting is preferred |
| ON Semiconductor SB5100 | Identical DO-201AD package and 100V rating, but 0.92V VF max and 200µA IR at 25°C | Higher conduction loss and leakage reduce efficiency in battery-backed systems | Acceptable for cost-sensitive consumer adapters where 0.07V VF penalty is tolerable |
Compared with VS-50SQ100 and SB5100, SR510 A0G delivers superior thermal interface (6°C/W RθJC), lower leakage (100µA), and AEC-Q101 qualification path-making it optimal for thermally constrained, high-reliability industrial and automotive-adjacent power supplies.

FAQ
What is the maximum junction temperature rating for SR510 A0G?
The SR510 A0G has a maximum junction temperature (TJ) of +125°C under continuous operation. This rating is validated per JEDEC standards and enables reliable use in sealed enclosures or high-ambient-temperature environments without forced cooling, provided thermal design respects the 6°C/W RθJC and 35°C/W RθJA limits specified in the SR510 A0G datasheet.
Is SR510 A0G RoHS and halogen-free compliant?
Yes, SR510 A0G is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and terminals are pure tin plated-ensuring compatibility with lead-free reflow processes and environmental compliance requirements for global electronics manufacturing.
Does SR510 A0G have AEC-Q101 qualification?
The SR510 A0G itself is not AEC-Q101 qualified; however, the functionally identical SR510H variant is explicitly qualified per AEC-Q101. Both share identical electrical parameters and DO-201AD packaging-only the H suffix denotes automotive stress testing. For automotive applications, specify SR510H; SR510 A0G remains suitable for industrial and telecom use.
What is the reverse leakage current specification for SR510 A0G at 100V and 125°C?
At 100V reverse voltage and 125°C junction temperature, the SR510 A0G exhibits ≤5 mA typical reverse leakage current. This value is confirmed in the "ELECTRICAL SPECIFICATIONS" table of the official TSC datasheet (Version J2105), and reflects stable performance under worst-case thermal stress in high-power converter secondaries.
How does the guard ring feature improve reliability in SR510 A0G?
The guard ring in SR510 A0G prevents premature edge breakdown under high dv/dt or transient overvoltage conditions-especially critical in switching power supplies exposed to line surges or inductive kickback. It extends device lifetime in real-world industrial environments where 10,000 V/µs dv/dt ratings are routinely challenged, as verified in TSC's AEC-Q101 stress tests for the SR510H variant.
