capability at 10/1000µs  
waveform, repetition rate  
(duty cycle): 0.01%  
• Excellent clamping  
capability  
• Fast response time:  
typically less than 1.0ps  
from 0 Volts to VBR min  
• Glass passivated junction  
• Low inductance  
• High temperature  
to reflow soldering  
guaranteed: 260°C/30sec  
Agency Approvals  
•Typical IR less than 1μA  
when VBR min>12V

• For surface mounted  
applications to optimize  
board space  
• VBR @TJ= VBR@25°C  
x (1+αT x (TJ - 25))  
(αT:Temperature  
Coefficient, typical value  
is 0.1%)  
• Plastic package is  
flammability rated V-0 per  
Underwriters Laboratories  
• Meet MSL level1, per  
J-STD-020, LF maximun  
peak of 260°C  
• Matte tin lead–free Plated  
• Halogen free and RoHS  
compliant  
• Pb-free E3 means 2nd  
level interconnect is  
Pb-free and the terminal  
finish material is tin(Sn)  
(IPC/JEDEC J-STD-  
609A.01)  
E230531  
• Low profile package  
Maximum Ratings andThermal Characteristics  
(TA=25OC unless otherwise noted)  
•Typical failure mode is  
short from over-specified  
voltage or current  
• Whisker test is conducted  
based on JEDEC  
JESD201A per its table 4a  
and 4c  
• IEC-61000-4-2 ESD

Notes:  
Applications  
1. Non-repetitive current pulse, per Fig.4 and derated above TJ (initial) =25ºC per Fig. 3.  
2. Mounted on 5.0x5.0mm copper pad to each terminal.  
3. Measured on 8.3ms single half sine wave or equivalent square wave for unidirectional device only.  
4. VF < 3.5V for single die parts and VF< 5.0V for stacked-die parts.  
5. For stacked die component details, please refer to part numbers labeled by * in Electrical Characteristics.  
TVS devices are ideal for the protection of I/O Interfaces,  
CC bus and other vulnerable circuits used inTelecom,  
V
Computer, Industrial and Consumer electronic applications.
