1PMT5.0AT1/T3 Series
Zener Transient
Voltage Suppressor
POWERMITE® Package
The 1PMT5.0AT1/T3 Series is designed to protect voltage
sensitive components from high voltage, high energy transients.
Excellent clamping capability, high surge capability, low Zener
impedance and fast response time. The advanced packaging
technique provides for a highly efficient micro miniature, space
saving surface mount with its unique heatsink design. The
POWERMITE has the same thermal performance as the SMA while
being 50% smaller in footprint area, and delivering one of the lowest
height profiles (1.1 mm) in the industry. Because of its small size, it
is ideal for use in cellular phones, portable devices, business
machines, power supplies and many other industrial/consumer
applications.
Specification Features:
Stand−off Voltage: 5.0 V − 58 V
Peak Power − 200 W @ 1 ms (1PMT5.0A − 1PMT36A)
− 175 W @ 1 ms (1PMT40A − 1PMT58A)
Maximum Clamp Voltage @ Peak Pulse Current
Low Leakage
Response Time is Typically < 1 ns
ESD Rating of Class 3 (> 16 kV) per Human Body Model
Low Profile − Maximum Height of 1.1 mm
Integral Heatsink/Locking Tabs
Full Metallic Bottom Eliminates Flux Entrapment
Small Footprint − Footprint Area of 8.45 mm2
POWERMITE is JEDEC Registered as DO−216AA
Lead Orientation in Tape: Cathode (Short) Lead to Sprocket Holes
Cathode Indicated by Polarity Band
Pb−Free Packages are Available
Mechanical Characteristics:
CASE: Void-free, transfer-molded, thermosetting plastic
FINISH: All external surfaces are corrosion resistant and leads are
readily solderable
MOUNTING POSITION: Any
MAXIMUM CASE TEMPERATURE FOR SOLDERING PURPOSES:
260°C for 10 Seconds
