The 1.5W HTD isolated DC/DC converter operates between -55°C and 155°C, while the non-isolated HTD DC/DC converters operate between -55°C and 185°C. Each model has two outputs and is designed using hybrid thick-film microcircuit technology, with the semiconductor material exposed and integrated with thick-film passive and conductive components on a ceramic substrate. The HTD design features optimized component and die bonding for high-temperature operation, and the hermetically sealed metal package protects the internal components for long-term reliability.
| DC/DC Converter | Temperature | Power (W) | Model | Input (VCC) | Outputs (VCC) |
| Hybrid, isolated | -55°C to 155°C | 1,5 | HTD1R5B-1200D | 6-20 | +/-5, +/-12 |
| Hybrid, not isolated | -55°C to 185°C | 1,5 | HTD1R5N-1200D | 6-20 | +/-5, +/-12 |
| Hybrid, not isolated | -55°C to 185°C | 1,5 | HTD1R5N-2800D | 14-40 | +/-5, +/-12 |
