What are the key features of RB068L-40TE25?
- 0.69 V maximum forward voltage reduces conduction losses by up to 40% versus standard silicon rectifiers at the same current
- 50 A non-repetitive peak forward current rating handles large inrush and surge events in power supply protection circuits
- High-reliability design meets demanding industrial and automotive application standards for long-term stable rectification
- Compact SMA (DO-214AC) 2-pin package enables high-density PCB placement in space-constrained power modules
What is RB068L-40TE25 used for?
The RB068L-40TE25 Schottky rectifier is used in switching power supply output rectification stages, reverse polarity protection circuits, and freewheeling diode positions in DC motor driver H-bridge designs. Its low 0.69 V forward voltage minimizes heat generation in high-current 12 V to 40 V power rails, improving overall converter efficiency. The 50 A surge current rating also makes it suitable for protecting circuits against inrush currents during power-on in industrial controllers and automotive accessory modules.

Frequently Asked Questions
What efficiency gain does the RB068L-40TE25's 0.69 V forward voltage provide over a standard PN junction rectifier at 3 A continuous current?
At 3 A forward current, a standard silicon PN diode has a forward voltage of approximately 1.0 V, dissipating 3 W. The RB068L-40TE25 with 0.69 V maximum VF dissipates only 2.07 W—a saving of 0.93 W per diode, or about 31% lower conduction loss. In a full-wave rectifier with 2 diodes conducting simultaneously, this saves nearly 1.86 W, which measurably improves thermal margins in compact power supplies.
For a 12 V automotive reverse-polarity protection circuit, is the RB068L-40TE25 voltage rating sufficient?
The RB068L-40TE25 has a 40 V reverse voltage rating, which provides a comfortable margin above the 12 V automotive load dump transients that can reach 28 V per ISO 7637-2 test pulse 5a. At 40 V, the diode withstands these transients with a 12 V safety margin, making it a reliable choice for battery-side reverse-polarity protection in 12 V automotive electronics without requiring a higher-rated component.
How does the 50 A non-repetitive peak forward current of the RB068L-40TE25 protect circuits during power-on inrush events?
The 50 A non-repetitive peak forward current rating means the RB068L-40TE25 can survive a single short-duration current surge—typically limited to 8.3 ms at 50 Hz (one half-cycle)—without permanent damage. In a 12 V switching supply with a 1000 µF bulk capacitor, the inrush current during initial power-on can spike to 20–40 A for milliseconds; the 50 A rating provides a robust safety margin to prevent rectifier failure during hot-plug or power cycling events.
What mounting and footprint considerations apply when replacing a DO-214AC through-hole rectifier with the SMA-package RB068L-40TE25?
The RB068L-40TE25 uses the SMA (DO-214AC) surface-mount package, which has a footprint of approximately 4.4 mm × 2.7 mm with a 2-pin SMD land pattern—much smaller than a DO-41 through-hole package that typically needs 7 mm lead spacing. Transitioning from through-hole to SMA reduces vertical clearance to under 2.5 mm, allowing the PCB to fit inside slimmer enclosures while improving thermal coupling to ground planes for better heat dissipation at currents above 1 A.
