New MicroSMP Miniature, High-Power-Density Package
for Schottky Rectifiers and Transient Voltage
Suppressors (TVS)
The Key Benefits:
- High-power-density Schottky rectifiers and TVS in space-saving 2.5 mm by 1.3 mm footprint with a 0.65 mm height
- High forward current up to 1 A in Schottky rectifier and 100 W (10/1000 μ s waveform) clamping power capability in TVS
- All the devices offer a high 25 A forward surge current capability for an 8.3 ms pulse
- 150 °C maximum operation junction temperature for Schottky rectifiers
- Low junction-to-lead thermal resistance of 30 °C/W FR-4 PCB with 6 mm by 6 mm copper pad area
- Provides improved reliability and a longer operational life span
The Features:
- More power in a smaller package
- Schottky Rectifiers rated up to 1 A at 110 °C lead temperature
- TVS rated up to 100 W at 10/1000 μs waveform
- Features solder pads that are compatible with other SMD devices
- No modification is needed to the PCB layout when they are used as higher-performing upgrades to existing devices
- Improve on all previous TVS products in similar package types by combining ESD transient protection with a superior surge clamping capability

The Key Applications:
- Schottky MicroSMP Rectifiers
- Secondary rectification and freewheeling diode functions for miniature ac-to-dc and dc-to-dc converters
- Flywheel and polarity protection for miniature power converters and portable electronic equipment such as digital cameras, MP3 players, navigation systems, GPS, and cellular phones
- Polarity protection of power lines and signal lines for industrial systems
- MicroSMP TVS
- Power and signal line protection for microprocessors, signal processing ICs, and logic circuits
- High-power voltage regulation for non-sensitive input voltage circuits in automotive and industrial electronics
The Perspective:
The new MicroSMP miniature package type for Schottky rectifiers and transient voltage suppressors (TVS) provides high current power density and low thermal resistance for space savings and improved reliability in handheld, portable, and miniature end-product designs. The devices feature a high forward current up to 1 A in the Schottky rectifiers and 100 W (10/1000 μs waveform) clamping-power capability in TVS. With a 2.5 mm by 1.3 mm footprint and low 0.65 mm height, the MicroSMP package has dimensions that are smaller than the SOD-123 and similar to SOD-323 package.
Availability:
Samples and production quantities of the new Schottky and TVS devices in the MicroSMP package are available now with lead times of eight weeks for larger orders.
