Product details
Overview
SR510 from Taiwan Semiconductor is a 5A, 100V Schottky barrier rectifier in DO-201AD package, featuring 0.85V forward voltage at 5A and 100µA reverse leakage at 25°C, optimized for high-efficiency DC/DC converters and automotive-grade power supplies.
For engineers reviewing the SR510 datasheet, SR510 pinout, SR510 application, or SR510 equivalent, key selection criteria include its AEC-Q101 qualification (when ordered as SR510H), 120A surge rating, 6°C/W junction-to-case thermal resistance, and low VF/IR trade-off at 100V VRRM.
Technical Context
This single-die Schottky rectifier uses a guard ring structure to enhance overvoltage robustness and supports continuous operation up to 150°C junction temperature. Its 10,000 V/µs dv/dt rating enables stable switching in fast-rising edge environments like synchronous buck converters.
The device delivers 5A average forward current with derating above 75°C ambient, leveraging a 35°C/W junction-to-ambient thermal resistance in standard PCB mount conditions. Reverse recovery is inherently negligible due to majority-carrier conduction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines usable input range in 48V–72V DC/DC front-ends |
| IF(AV) | 5 A - Continuous forward current rating; supports 60W+ output at 12V with appropriate heatsinking |
| VF @ 5A, 25°C | 0.85 V - Low conduction loss enabling >92% efficiency in 100kHz–500kHz SMPS designs |
| IR @ 100V, 25°C | 100 µA - Minimal leakage ensures low standby power in always-on systems |
| IFSM (8.3ms) | 120 A - Withstands inrush surges from bulk capacitors without degradation |
| RθJC | 6 °C/W - Enables direct thermal coupling to heatsink or copper pour for high-power density layouts |
| TJ max | 150 °C - Supports under-hood automotive applications per AEC-Q101 when ordered as SR510H |
Pinout & Package
DO-201AD axial-leaded package with cathode band marking; leads are pure tin plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead without band) | Forward current entry point | Connected to input source or switch node; requires adequate trace width for 5A continuous |
| Cathode (lead with band) | Forward current exit / reverse blocking terminal | Connected to output rail or ground return; polarity must be observed to prevent catastrophic failure |

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 VF = 0.78V @ 5A (25°C); TO-220AC package, not DO-201AD | Requires PCB layout change; better thermal performance but larger footprint | Select when higher thermal conductivity is critical and board space allows TO-220 mounting |
| ON Semiconductor SB5100 | 100V VRRM, 5A IF, VF = 0.82V @ 5A (25°C); DO-201AD package, but IR = 200µA @ 100V (25°C) | Higher leakage may impact ultra-low-power standby designs | Select when cost sensitivity outweighs minor leakage penalty and AEC-Q101 is not required |
Compared with VS-50SQ100 and SB5100, the SR510 offers the best combination of DO-201AD compatibility, AEC-Q101 availability (as SR510H), and balanced VF/IR for mid-voltage industrial and automotive power stages.

FAQ
What is the maximum junction temperature rating for SR510?
The SR510 has a maximum junction temperature (TJ max) of 150°C, enabling operation in high-ambient environments such as automotive engine compartments or enclosed industrial enclosures. This rating applies to all SR510 variants, including standard and AEC-Q101-qualified SR510H versions, and is validated per JEDEC JESD22-A108.
Is SR510 pin-compatible with other parts in the SR502–SR520 family?
Yes, all SR502–SR520 parts share identical DO-201AD packaging, anode/cathode pinout, and mechanical dimensions. The SR510 can replace SR509 or SR515 on the same PCB layout, though electrical parameters-including VRRM, VF, and IR-must be verified for functional compatibility in the target application.
Does SR510 meet automotive qualification standards?
The SR510 itself is not AEC-Q101 qualified; however, the SR510H variant-identical in all electrical and mechanical specifications except for extended reliability testing-is fully AEC-Q101 qualified. Engineers requiring automotive compliance must specify SR510H, not SR510, in procurement and design documentation.
What is the forward voltage drop of SR510 at 5A and 125°C?
Per the electrical specifications table, the SR510's forward voltage (VF) is specified only at 25°C (0.85V max). At 125°C, VF decreases due to negative temperature coefficient of Schottky diodes; typical data shows ~0.72V at 5A and 125°C, though this value is not guaranteed and should be confirmed via characterization in final design conditions.
Can SR510 be used in surface-mount assemblies?
No, the SR510 is supplied in DO-201AD axial-leaded through-hole package and is not suitable for standard SMT reflow processes. It requires wave soldering or hand-soldering. For surface-mount alternatives, consider TSC's SMB/SMA-packaged equivalents (e.g., SB5100 in SMA) or evaluate layout adaptation for axial lead retention.
