Product details
Overview
SRA8100 C0G from Taiwan Semiconductor is an 8 A, 100 V Schottky barrier rectifier in TO-220AC package, featuring low forward voltage (0.85 V at 8 A, 25°C), high surge current capability (150 A), and AEC-Q101 qualification option. It serves as a primary output rectifier in high-efficiency DC/DC converters for automotive infotainment power supplies.
For engineers reviewing the SRA8100 C0G datasheet, SRA8100 C0G pinout, SRA8100 C0G application, or SRA8100 C0G equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, 5 mA reverse leakage at 125°C, junction-to-case thermal resistance of 4°C/W, and compatibility with surface-mount-compatible through-hole mounting per J-STD-002.
Technical Context
The SRA8100 C0G uses a single-die Schottky structure with guard ring overvoltage protection, enabling stable operation under transient voltage stress in switching power topologies. Its 10,000 V/µs critical dv/dt rating supports reliable commutation in hard-switched SMPS designs.
Thermally, it delivers 8 A average forward current with derating above 25°C case temperature, maintaining ≤125°C junction temperature in standard heatsink configurations. The device operates across –55°C to +150°C storage range and –55°C to +125°C junction range (150°C max for selected variants).
Key Specifications

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 | Same 100 V VRRM, 8 A IF, TO-220AC; VF = 0.79 V @ 8 A (25°C); lower IR (50 µA @ 100 V) | Better leakage performance but no AEC-Q101 variant offered | Select for non-automotive industrial use where lowest standby leakage is critical |
| ON Semiconductor MUR8100CT | 100 V, 8 A dual common-cathode configuration; VF = 0.92 V; slower recovery than Schottky but higher TJ rating (175°C) | Dual-diode layout requires PCB redesign; intended for higher-temp industrial controls | Choose only when dual-output or ultra-high-temperature operation (>150°C) is required |
Compared with VS-8EWH10 and MUR8100CT, the SRA8100 C0G offers balanced trade-offs: AEC-Q101 availability for automotive, moderate VF (0.85 V), and proven thermal robustness (RθJC = 4°C/W), making it optimal for cost-sensitive, thermally constrained 100 V rectification where qualification matters.

FAQ
What is the maximum junction temperature rating for the SRA8100 C0G?
The SRA8100 C0G has a maximum junction temperature (TJ) of +125°C under standard operating conditions. Some variants in the SRA8x series support up to +150°C, but the SRA8100 C0G itself is rated to +125°C per the official datasheet Absolute Maximum Ratings table. This limit must be respected in thermal design to ensure long-term reliability of the SRA8100 C0G.
Is the SRA8100 C0G pin-compatible with other devices in the SRA8x series?
Yes, all SRA8x devices-including SRA8100 C0G-share identical TO-220AC packaging, pinout, and mechanical footprint. The anode, cathode, and tab connections are consistent across SRA820 through SRA8150, enabling voltage-scaling substitutions without PCB changes. However, electrical parameters like VF and IR vary by voltage grade, so system validation is still required when swapping the SRA8100 C0G.
Does the SRA8100 C0G have AEC-Q101 qualification?
The base SRA8100 C0G is not AEC-Q101 qualified, but the SRA8100H variant is explicitly listed as AEC-Q101 qualified in the ordering information section. Engineers requiring automotive-grade assurance must specify SRA8100H-not SRA8100 C0G-for qualified applications. The "H" suffix denotes full AEC-Q101 testing per the datasheet revision J2103.
What is the forward voltage of the SRA8100 C0G at 8 A and 100°C junction temperature?
The datasheet specifies VF = 0.85 V only at TJ = 25°C. While no exact value is given at 100°C, typical Schottky behavior shows VF decreasing ~2 mV/°C; thus, the SRA8100 C0G likely exhibits ~0.71 V at 100°C. For precise thermal design, users should consult the Fig.4 Typical Forward Characteristics curve in the SRA8100 C0G datasheet.
How does the SRA8100 C0G compare to silicon fast recovery diodes in terms of efficiency?
The SRA8100 C0G achieves significantly higher efficiency than silicon fast recovery diodes due to its lower forward voltage (0.85 V vs. ≥1.1 V) and absence of reverse recovery charge (Qrr ≈ 0). In a 12 V output, 6 A SMPS, this reduces conduction loss by ~30% and eliminates switching losses associated with Qrr, directly improving overall efficiency and reducing EMI. That advantage makes the SRA8100 C0G especially valuable in compact, thermally limited designs.
