Product details
Overview
SR810 from Taiwan Semiconductor is a single-die Schottky barrier rectifier in DO-201AD package, rated for 100 V repetitive peak reverse voltage (VRRM), 8 A average forward current (IF), and 150 A non-repetitive surge current (IFSM), with 0.92 V typical forward voltage at 8 A and 25°C - used in high-efficiency DC/DC converters and industrial power adapters.
For engineers reviewing the SR810 datasheet, SR810 pinout, SR810 application, or SR810 equivalent, key selection criteria include its 100 V VRRM rating, low VF performance at high IF, AEC-Q101 qualification option (SR810H), thermal resistance of 40°C/W, and DO-201AD mechanical compatibility with legacy through-hole power rectifier footprints.
Technical Context
This device operates as a unidirectional power rectifier with guard ring–enhanced overvoltage protection and a junction temperature range up to +150°C. Its 10,000 V/µs critical dv/dt rating supports fast-switching SMPS topologies without spurious turn-on.
The SR810 exhibits 100 µA maximum reverse leakage at rated VR and 25°C, and 5 mA at 125°C - enabling stable operation in thermally demanding environments. Its 40°C/W junction-to-ambient thermal resistance is measured under standard JEDEC conditions on FR-4 board with 1-inch² copper pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage; defines safe operating limit in flyback or buck-derived secondary-side rectification |
| IF | 8 A - continuous average forward current at TA = 75°C; determines steady-state power delivery capability |
| IFSM | 150 A - non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients in AC/DC front-ends |
| VF @ 8A, 25°C | 0.92 V typical - directly reduces conduction loss and improves efficiency in high-current, low-voltage output stages |
| IR @ 100V, 25°C | ≤100 µA - low leakage preserves standby power budget and prevents unintended bias in high-impedance circuits |
| RθJA | 40 °C/W - thermal resistance enables ~3.2 W dissipation before reaching 150°C junction limit on standard PCB layout |
| TJ max | +150 °C - extended junction rating supports operation in sealed enclosures or high-ambient industrial environments |
Pinout & Package
DO-201AD package: axial-leaded, molded plastic case with cathode band marking; leads are pure tin plated, solderable per J-STD-002; polarity indicated by cathode band; weight ≈1.10 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead without band) | Forward current entry point | Connected to transformer secondary or switch node; must handle full 8 A DC + ripple |
| Cathode (lead with band) | Forward current exit / reverse-blocking terminal | Connected to output capacitor and load; reverse voltage appears across this terminal during off-state |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Prevents premature edge breakdown under high dv/dt or transient overvoltage, improving reliability in noisy switching environments |
| AEC-Q101 qualified version available (SR810H) | Validated for automotive under-hood applications including engine control modules and body electronics |
| RoHS and halogen-free compliance | Meets IEC 61249-2-21; supports environmentally regulated industrial and consumer product certifications |
| 10,000 V/µs dv/dt rating | Enables use in high-frequency (>100 kHz) topologies without snubber networks or gate drive isolation compromises |

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-8EWH10FN-M3/45 | Same DO-201AD package, 100 V VRRM, 8 A IF, but VF = 0.82 V typ @ 8 A - lower conduction loss; RθJA = 45°C/W - slightly worse thermal performance | Preferred where efficiency > thermal margin; not AEC-Q101 qualified | Select for commercial-grade high-efficiency designs where automotive qualification is unnecessary |
| ON Semiconductor SB8100 | DO-201AD, 100 V VRRM, 8 A IF, VF = 0.95 V typ @ 8 A - marginally higher VF; IR = 200 µA @ 100 V - double the leakage | Suitable for cost-sensitive industrial adapters; lacks AEC-Q101 variant | Choose when BOM cost is primary driver and leakage sensitivity is low |
Compared with VS-8EWH10FN-M3/45 and SB8100, the SR810 offers balanced VF–leakage trade-off, AEC-Q101 availability (as SR810H), and tighter IR spec (≤100 µA), making it optimal for automotive-adjacent and thermally constrained industrial power supplies.

FAQ
What is the maximum junction temperature rating for SR810?
The SR810 has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table in the official TSC datasheet (Version J2105). This allows full 8 A current operation at elevated ambient temperatures when mounted on standard PCB layouts with adequate copper area. The SR810's thermal design supports applications where ambient exceeds +75°C, such as enclosed industrial power modules.
Is SR810 available in an AEC-Q101 qualified version?
Yes - the SR810H variant is explicitly qualified to AEC-Q101 standards, as confirmed in the Ordering Information section (Page 3, Version J2105). The "H" suffix denotes automotive qualification, including stress testing for temperature cycling, humidity, and mechanical shock. Standard SR810 is not AEC-Q101 qualified; only SR810H carries this certification.
What is the forward voltage of SR810 at 8 A and 125°C?
The SR810 datasheet does not specify VF at 125°C - only provides VF = 0.92 V typical at 8 A and 25°C (Electrical Specifications, Page 2). However, Figure 4 (Typical Forward Characteristics) shows VF increases to ~1.05 V at 8 A and 125°C. This temperature-dependent rise is consistent with Schottky physics and must be accounted for in worst-case thermal design.
Does SR810 have a guard ring structure, and what is its function?
Yes - the SR810 incorporates a guard ring structure, explicitly listed under FEATURES (Page 1, Version J2105). This design feature suppresses edge breakdown during high dv/dt transients or overvoltage events, enhancing ruggedness in switching power supplies. It directly contributes to the device's 10,000 V/µs critical rate of rise of off-state voltage rating.
What packaging options are available for SR810?
SR810 is offered in DO-201AD package with two packing formats: 1,250 units per tape-and-reel (ordering code SR810 or SR810H) and 500 units per ammo box (ordering codes SR810A0G or SR810HA0G). All variants use pure tin-plated leads compliant with J-STD-002 and meet JESD 201 Class 2 whisker resistance requirements.
