Llttelfuse* Expertise Applied | Answers Delivered TVS DiodesSurface Mount - 600W > TPSMB seriesTPSMB Series I ^ automotive grade HE [RqhS TO @ © The TPSMB series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. Agency Approvals Maximum Ratings and Thermal Characteristics (TA=25OC unless otherwise noted) Notes: 1. Non-repetitive current pulse, per Fig.4 and derated above TA=250C per Fig. 3. 2. Mounted on copper pad area of 0.2x0.2" (5.0 x 5.0mm) to each terminal. 3. Measured on 8.3ms single half sine wave or equivalent square wave for unidirectional component only,duty cycle=4 per minute maximum. 4. VF < 3.5V for part number below 300A, VF < 5.0V for part number with 300A or above. DescriptionFeatures • High reliability application and automotive grade AEC Q101 qualified • Surface mount component to optimize board space • Low profile package • 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 • ESD protection of data lines in accordance with IEC 61000-4-2 30kV(Air), 30kV (Contact) • EFT protection of data lines in accordance with IEC 61000-4-4 • Glass passivated chip junction • 600W PPPM (peak pulse power) capability at 10/1000ps waveform, repetition rate (duty cycles):0.01% • Fast response time: typically less than 1.0ns from 0V to VBR min • Excellent clamping capability • Low incremental surge resistance • Typical IR < 1pA for Vr>10.2V • UL Recognized compound meeting flammability rating V-0 • Meet MSL level1, per J-STD-020, High temperature soldering guaranteed: 260°C/10 seconds at terminals • 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 Functional Diagram TVS components are ideal for the protection of I/O Interfaces, VCC bus and other vulnerable circuits used in Automotive applications. © 2018 Littelfuse, Inc.
