• Very fast response time

• Low incremental surge resistance

• Meets MSL level 1, per J-STD-020, LF maximum

peak of 260 °C

DO-214AC (SMA)

• Solder dip 260 °C, 40 s

• Component in accordance to RoHS 2002/95/EC

and WEEE 2002/96/EC

2.5 W

40 A

• Respect thermal resistance (PCB Layout) - as the

temperature coefficient also contributes to the

clamping voltage

I_FSM

T_Jmax.

150 °C

• Select minimum breakdown voltage, so you get

acceptable power dissipation and PCB tie point

temperature

TYPICAL APPLICATIONS

Use in sensitive electronics protection against voltage

transients induced by inductive load switching and

lighting on ICs, MOSFET, signal lines of sensor units

for consumer, computer, industrial, automotive and

telecommunication.

• Devices with higher breakdown voltage will have a

shorter conduction time and will dissipate less

power

• Clamping voltage is influenced by internal resistance

- design approximation is 7 V per 100 mA slope

• Keep temperature of TVS lower than TOPSwitch

MECHANICAL DATA

Case: DO-214AC (SMA)

Molding compound meets UL 94 V-0 flammability

rating

as a recommendation

• Maximum current is determined by the maximum

T and can be higher than 300 mA

Base P/N-E3 - RoHS compliant, commercial grade

Base P/NHE3 - RoHS compliant, high reliability/

automotive grade (AEC Q101 qualified)

• Contact supplier for different clamping voltage/

current arrangements

• Minimum breakdown voltage can be customized for

other applications. Contact supplier

Terminals: Matte tin plated leads, solderable per

J-STD-002 and JESD22-B102

• TOPSwitch is a registered trademark of Power

Integrations, Inc.

E3 suffix meets JESD 201 class 1A whisker test, HE3
