Diodes' SBRT3M40P1 and SBRT3U40P1 Trench SBRs are optimized to give low reverse-current leakage combined with low forward-voltage drops in a small form factor. This capability addresses requirements for input bridge rectifiers in solid-state lighting (SSL) applications focused on 12 VAC LED retrofit lamps that provide a more efficient and longer life alternative to popular MR16 halogen bulbs. These 40 V rated Trench SBRs maximize the 1 A bridge rectifier efficiency and power density with only a 0.29 V forward-voltage drop in a compact PowerDI123 footprint of 6.75 mm2.
Features
- Low reverse-current leakage (IR)
- At +125°C, the SBRT3M40P1 has an IR of 1.2 mA (12 V) giving immunity to thermal runaway under high ambient temperature environments
- PowerDI123 package reduces footprint
- 6.75 mm2 footprint and <1 mm height, compared to SMA of 16 mm2 and 2 mm, respectively, which significantly saves space in the MR16 retrofit
- Low forward-voltage drop (VF)
- Only 0.29 V VF increases the bridge rectifier efficiency
- Sufficient blocking voltage (VRRM)
- 40 V provides sufficient headroom for the intended 12 VAC input supply
Applications
- Intended for 12 VAC bridge rectifier inputs of retrofit MR16 LED bulbs. Replacing the halogen incandescent filament with LED lighting offers greater efficiency and a longer lifespan overall reducing the total cost of ownership
