MMBZxxVAL Dual Channel Zener Diode

1 Features

• IEC 61000-4-2 ESD protection:

– ±30kV contact discharge

– ±30kV air-gap discharge

• IEC 61643-321 surge protection:

– Up to 1.7A (10/1000µs)

• Low leakage current: 50nA (max)

• Temperature range: –55°C to +150°C

• Leaded packages used for automatic optical

inspection (AOI)

2 Applications

• Overvoltage protectection

• CAN/LIN transient suppression

• Dual channel unidirectional or single channel

bidirectional

3 Description

The MMBZxxVAL is a dual channel unidirectional or

single channel bidirectional ESD in common anode

configuration. The device's relatively low capacitance

and low leakage features enable use in higher speed

applications.

The MMBZxxVAL is packaged in the SOT-23,

providing two channels of robust transient protection

in one space-efficient form factor.
