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)

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit

values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,

damage may occur and reliability may be affected.
