SZ3KASMC Series

Automotive, Surface Mount 3000 W in DO-214AB

RoHS

Pb e3

Description

The SZ3KASMC series is designed to protect voltage sensitive

components from high voltage, high energy transients. They have

excellent clamping capability, high surge capability, low zener

impedance and fast response time. The SZ3KASMC series is

supplied in the Littelfuse exclusive, cost-effective, highly reliable

DO-214AB package and it is ideal for use in automotive electronic

applications.

Stresses exceeding maximum ratings may damage the device. Maximum ratings are stress

ratings only. Functional operation above the recommended operating conditions is not

implied. Extended exposure to stresses above the recommended operating conditions may

affect device reliability.

1. 10 x 1000 µs, non−repetitive.

Applications

2. 1 in square copper pad, FR−4 board.

TVS devices are ideal for the protection of I/O Interfaces, V_CCbus

and other vulnerable circuits used in automotive application.

3. FR−4 board, using Littelfuse minimum recommended footprint

4. 1/2 sine wave (or equivalent square wave), PW = 8.3 ms, duty cycle = 4 pulses per

minute maximum.
