EF Series, high thermal efficiency, complete power control circuits in a single package
The EF Series offers high thermal efficiency and complete power control in a single package. The datasheet lists the available circuit options, load current ratings, and detailed electrical specifications such as maximum DC output current, voltage drop, junction temperature range, and isolation voltage.
Mechanical specifications include typical weight, mounting dimensions, and safety warnings. The document also contains agency approvals (RoHS), hazard warnings in multiple languages, and an annex with environmental compliance information for Chinese electronic waste standards.
| Maximum DC Output Current | 50 A – 125 A (depending on variant) |
|---|---|
| Maximum Voltage Drop @ Peak Current | 1.7 V @ 50 A, 1.85 V @ 75 A, 1.4 V @ 100 A, 1.55 V @ 125 A |
| Operating Junction Temperature Range | -40 °C to 125 °C |
| Isolation Voltage | 2500 V rms (all variants) |
| Maximum Thermal Resistance, Junction‑to‑Base | 0.87 °C/W – 0.32 °C/W (depending on variant) |
The EF Series can deliver up to 125 A, with specific variants rated at 50 A, 75 A, 100 A, or 125 A.
All EF Series variants have an isolation voltage of 2500 V rms.
