SMBJ170A 二极管 Littelfuse

SMBJ170A    Transient Voltage Suppression Diodes

Surface Mount – 600W > SMBJ series

ESD 抑制器/TVS 二极管 170Vr 600W 2.2A 5% UniDirectional

Description SMBJ170A

The SMBJ is designed specifically to protect sensitive

electronic equipment from voltage transients induced by

lightning and other transient voltage events.

Features SMBJ170A

• 600W peak pulse power capability at 10/1000μs waveform, repetition rate (duty cycles):0.01%

• Excellent clamping capability

• Low incremental surge resistance

• Typical IR less than 1μA when VBR min>12V

• For surface mounted applications to optimize board space

• Low profile package

• Typical failure mode is a short circuit condition for current events exceeding component rating

• Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c

• IEC-61000-4-2 ESD 30kV(Air), 30kV (Contact)

• EFT protection of data lines in accordance with IEC 61000-4-4

• Built-in strain relief

• Fast response time: typically less than 1.0ps from 0V to BV min

• High temperature to reflow soldering guaranteed: 260°C/40sec

• 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 UL-94

• Meet MSL level1, per J-STD-020, lead-frame 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)

Applications SMBJ170A

TVS devices are ideal for the protection of I/O Interfaces,  VCC bus and other vulnerable circuits used in Telecom,  Computer, Industrial and Consumer electronic  applications.
