When 1000V Meets Real-World Challenges
Hidden inside an industrial motor control cabinet in Shenzhen, 48 Holly HC10AR diodes have been quietly operating for 18,000+ hours. This 20A/1000V rectifier bridge handles peak currents up to 150A during motor startups – a real-world validation of its rugged design.
Beyond Spec Sheets: Thermal Performance That Matters
At 85% load (17A continuous), our thermal imaging tests show:
- Case temperature stabilizes at 68°C (no heatsink)
- Only 1.25V forward voltage drop at 20A
- 0.02% failure rate in 2023 batch testing (n=5,000 units)
EV Charger Manufacturer’s Success Story
Zhuhai-based EVE Chargers replaced competitor parts with HC10AR in their 80kW DC fast chargers:
| Metric | Before | After |
|---|---|---|
| MTBF | 4,200h | 6,800h |
| Efficiency | 93.7% | 95.2% |
“The 1000V rating gives us 23% more headroom than industry standard,” said lead engineer Wang Lei.
Counterfeit Detection Tip
Genuine HC10AR features:
– Laser-etched logo (not printed)
– Matte black epoxy coating
– Precise 19.3mm pin spacing
As power systems push beyond 800V architectures, Holly’s solution combines proven reliability with forward-looking design – exactly what engineers need when margins matter.
