Product details
Overview
SR510HA0G from Taiwan Semiconductor is a 5A, 100V AEC-Q101-qualified Schottky barrier rectifier in DO-201AD package, featuring 0.85V max forward voltage at 5A and 100µA max reverse leakage at 25°C, used in automotive-grade DC-DC converters and industrial SMPS.
For engineers reviewing the SR510HA0G datasheet, SR510HA0G pinout, SR510HA0G application, or SR510HA0G equivalent, key selection criteria include its 100V VRRM rating, 120A IFSM surge capability, AEC-Q101 qualification, thermal resistance (RθJA = 35°C/W), and DO-201AD mechanical compatibility with high-reliability power conversion designs.
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 junction temperature range spans –55°C to +150°C, supporting operation in under-hood automotive environments.
The device delivers low conduction loss via 0.85V VF max at 5A/25°C and maintains stable blocking performance with 10,000 V/µs dv/dt rating and 100µA IR max at rated VR and 25°C - critical for high-frequency switching topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse voltage; defines safe operating ceiling in bridge or freewheeling configurations |
| IF | 5 A - continuous forward current; supports sustained 5A DC output in compact SMPS designs |
| VF (max) | 0.85 V @ 5A, 25°C - low conduction loss enabling >92% efficiency in 12V–48V DC-DC stages |
| IFSM | 120 A - non-repetitive surge rating; withstands inrush and fault currents without failure |
| IR (max) | 100 µA @ 100V, 25°C - minimal leakage ensures stable hold-off in standby and light-load modes |
| RθJA | 35 °C/W - thermal resistance from junction to ambient; enables natural convection cooling in enclosed enclosures |
| TJ max | +150 °C - extended junction temperature rating supports AEC-Q101 automotive qualification |

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-50SQ030 | 30V VRRM, 5A IF, 0.45V VF max - lower voltage rating, lower VF | Not suitable for 100V bus applications; limited to ≤30V secondary-side use | Select only if system VR never exceeds 30V and lowest possible VF is prioritized over voltage margin |
| ON Semiconductor SB5100 | 100V VRRM, 5A IF, 0.82V VF max, non-AEC-Q101 | Lacks automotive qualification; identical electrical specs but no stress-test validation | Acceptable for industrial/commercial designs where AEC-Q101 is not mandated |
Compared with VS-50SQ030 and SB5100, SR510HA0G uniquely combines 100V rating, AEC-Q101 qualification, and 120A surge capability - making it the only option qualified for under-hood automotive DC-DC converters requiring both voltage headroom and transient resilience.

FAQ
What is the maximum junction temperature rating for SR510HA0G?
The SR510HA0G has a maximum junction temperature (TJ max) of +150°C, validated under AEC-Q101 stress testing. This rating allows reliable operation in under-hood automotive applications and high-ambient industrial environments. The SR510HA0G's thermal design - including RθJA = 35°C/W and RθJC = 6°C/W - supports sustained 5A conduction at elevated temperatures when properly mounted.
Is SR510HA0G pin-compatible with other DO-201AD Schottky rectifiers?
Yes, SR510HA0G uses the standard DO-201AD axial package with anode/cathode lead configuration matching industry-standard footprints. Its mechanical dimensions (7.62 mm length, 2.72 mm diameter, 5.08 mm lead spacing) and cathode-band polarity marking ensure direct PCB footprint compatibility with other DO-201AD rectifiers like SB5100 or MBR5100.
Does SR510HA0G meet automotive qualification standards?
Yes, SR510HA0G is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code. This certification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - confirming suitability for automotive power systems such as ECUs, ADAS modules, and body control units.
What is the forward voltage specification for SR510HA0G at 5A and 100°C junction temperature?
The SR510HA0G datasheet specifies VF ≤ 0.85V at 5A and 25°C; while no exact VF value is given at 100°C, typical Schottky behavior shows VF decreases ~2 mV/°C. Thus, SR510HA0G VF at 5A and 100°C is approximately 0.71V - confirmed by Fig.4 (Typical Forward Characteristics) showing consistent sub-0.75V behavior up to 125°C.
How does the guard ring feature improve reliability in SR510HA0G?
The guard ring in SR510HA0G enhances edge termination robustness, preventing premature avalanche breakdown at the die periphery during voltage transients. In real-world use, this allows SR510HA0G to sustain 10,000 V/µs dv/dt and survive repeated 100V+ overshoot events - critical for snubber circuits and motor drive clamping where fast-switching IGBTs generate steep voltage edges.
