Product details
Overview
SR810HA0G from Taiwan Semiconductor is an AEC-Q101-qualified 8A, 100V Schottky barrier rectifier in DO-201AD package, featuring 0.92V forward voltage at 8A/25°C, 150A surge capability, and guard ring overvoltage protection-used in automotive-grade DC-DC converters and industrial SMPS.
For engineers reviewing the SR810HA0G datasheet, SR810HA0G pinout, SR810HA0G application, or SR810HA0G equivalent, key selection factors include its 100V VRRM, 125°C/150°C junction temperature range, AEC-Q101 qualification status, low VF trade-off versus higher-voltage variants, and DO-201AD mechanical compatibility with high-reliability power stages.
Technical Context
This device operates as a single-die, unidirectional Schottky rectifier optimized for high-efficiency switching power conversion. Its guard ring structure enhances ruggedness against transient overvoltage, while the pure tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.
The SR810HA0G delivers 100V repetitive peak reverse voltage with 10,000 V/µs critical dv/dt rating and exhibits 100 µA max reverse leakage at rated VR and 25°C-enabling stable operation in noisy automotive and industrial environments where fast switching and low conduction loss are prioritized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum continuous reverse blocking voltage before breakdown; defines usable input voltage headroom in buck or flyback topologies. |
| IF | 8 A - Average forward current rating at case temperature ≤75°C; sets continuous power handling in thermally managed layouts. |
| IFSM | 150 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current robustness in adapter and converter inputs. |
| VF | 0.92 V @ 8A, 25°C - Low conduction loss improves efficiency and reduces thermal stress vs. silicon diodes in high-frequency SMPS. |
| IR | 100 µA @ 100V, 25°C - Low leakage preserves standby power and prevents unintended discharge in hold-up capacitors. |
| TJ max | 125°C / 150°C - Dual-rated junction temperature enables extended operation in under-hood or enclosed industrial enclosures. |
| RθJA | 40 °C/W - Thermal resistance from junction to ambient; informs heatsink requirement when operating near IF limit. |
Pinout & Package
DO-201AD axial-leaded package with cathode band marking; 1.10 g mass; UL 94V-0 molding compound; polarity indicated by single black band on cathode end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead without band) | Forward current entry point | Connected to lower-potential node (e.g., switch node in synchronous rectification or transformer secondary center-tap). |
| Cathode (lead with black band) | Forward current exit / reverse blocking terminal | Connected to output rail or positive bus; must withstand full VRRM during off-state with minimal leakage. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive power electronics including engine control units and ADAS power supplies requiring zero-failure reliability. |
| Guard ring structure | Prevents edge breakdown under voltage transients, increasing design margin in unregulated or line-voltage surge-prone applications. |
| Pure tin plating | Ensures consistent solder wetting and long-term intermetallic stability per J-STD-002, critical for reflow and wave soldering in high-volume manufacturing. |
| Halogen-free construction | Complies with IEC 61249-2-21, supporting RoHS and WEEE compliance in export-bound industrial and automotive systems. |
| 10,000 V/µs dv/dt rating | Enables reliable operation in fast-switching GaN or SiC-based converters where rapid voltage transitions occur across the device. |

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-8EWH10-M3 | Same DO-201AD package, 8A/100V, but VF = 0.82V @ 8A (lower), no AEC-Q101 qualification. | Preferred for cost-sensitive consumer SMPS where automotive qualification is unnecessary. | Select when lower forward drop is prioritized and automotive reliability testing is not required. |
| ON Semiconductor SB8100E | DO-201AD, 8A/100V, VF = 0.95V @ 8A, AEC-Q101 qualified, but IR = 200 µA @ 25°C (higher leakage). | Suitable for same automotive applications but requires verification of leakage impact on standby power budget. | Choose if supply chain diversification is needed and higher IR is acceptable in the target thermal environment. |
Compared with VS-8EWH10-M3 and SB8100E, the SR810HA0G uniquely balances AEC-Q101 compliance, 0.92V VF, and 100 µA IR-making it optimal for automotive and industrial designs demanding verified reliability without sacrificing efficiency or leakage performance.

FAQ
What is the maximum junction temperature rating for SR810HA0G?
The SR810HA0G has dual-rated maximum junction temperature: 125°C for standard operation and 150°C for extended thermal conditions. This allows flexible thermal design in constrained spaces-such as under-hood automotive modules-provided derating curves from the datasheet are followed for IF versus TJ.
Is SR810HA0G pin-compatible with other parts in the SR8xx series?
Yes, all SR8xx devices-including SR810HA0G-share identical DO-201AD package dimensions, lead spacing, and axial pinout (anode/cathode). However, VRRM, VF, and IR differ across the series, so electrical substitution requires validation of voltage margin and thermal performance in the target circuit.
Does SR810HA0G require a heatsink in typical 8A operation?
At 8A average forward current and 25°C ambient, SR810HA0G's 40°C/W RθJA results in ~32°C junction rise above ambient-well within its 125°C limit. A heatsink is generally unnecessary unless ambient exceeds 75°C or duty cycle approaches 100%; PCB copper area ≥1 cm² per lead improves thermal performance.
What does the "H" and "A0G" suffix mean in SR810HA0G?
In SR810HA0G, "H" denotes AEC-Q101 qualification, confirming automotive-grade reliability testing; "A0G" specifies DO-201AD packaging in 500-unit ammo box packaging with green compound (halogen-free) and standard date/lot coding per TSC's ordering matrix.
How does SR810HA0G's reverse leakage compare to SR805HA0G at 100V?
At 100V reverse bias and 25°C, SR810HA0G specifies ≤100 µA IR, while SR805HA0G (60V-rated) is rated ≤500 µA under same conditions. The lower leakage of SR810HA0G reflects tighter process control for higher-voltage Schottky structures, benefiting low-power standby and precision sensing circuits.
