1 / 5 page SM15T Series www.vishay.com Vishay General Semiconductor Revision: 13-Dec-13 1 Document Number: 88380 For technical questions within your region: DiodesAmericas@vishay.com, DiodesAsia@vishay.com, DiodesEurope@vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE. THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 Surface Mount TRANSZORB® Transient Voltage Suppressors DEVICES FOR BI-DIRECTION APPLICATIONS For bi-directional devices use CA suffix (e.g. SM15T12CA). Electrical characteristics apply in both directions. APPLICATION NOTES A 1500 W (SMC) device is normally selected when the threat of transients is from lightning induced transients, conducted via external leads or I/O lines. It is also used to protect against switching transients induced by large coils or industrial motors. Source impedance at component level in a system is usually high enough to limit the current within the peak pulse current (IPP) rating of this series. In an overstress condition, the failure mode is a short circuit. FEATURES • Low profile package • Ideal for automated placement • Glass passivated chip junction • Available in uni-directional and bi-directional • 1500 W peak pulse power capability with a 10/1000 μs waveform • Excellent clamping capability • Low inductance • Meets MSL level 1, per J-STD-020, LF maximum peak of 260 °C • AEC-Q101 qualified • Material categorization: For definitions of compliance please see www.vishay.com/doc?99912 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. MECHANICAL DATA Case: DO-214AB (SMCJ) Molding compound meets UL 94 V-0 flammability rating Base P/N-E3 - RoHS-compliant and commercial grade Base P/NHE3 - RoHS-compliant and AEC-Q101 qualified Terminals: Matte tin plated leads, solderable per J-STD-002 and JESD 22-B102 E3 suffix meets JESD 201 class 2 whisker test, HE3 suffix meets JESD 201 class 2 whisker test Polarity: For uni-directional types the band denotes cathode end, no marking on bi-directional types Notes (1) Non-repetitive current pulse, per fig. 3 and derated above TA = 25 °C per fig. 2. (2) Mounted on 0.31" x 0.31" (8.0 mm x 8.0 mm) copper pads to each terminal PRIMARY CHARACTERISTICS VWM 5.8 V to 188 V VBR uni-directional 6.8 V to 220 V VBR bi-directional 6.8 V to 220 V PPPM 1500 W PD 6.5 W IFSM (uni-directional only) 200 A TJ max. 150 °C Polarity Uni-directional, bi-directional Package DO-214AB (SMCJ) DO-214AB (SMCJ) MAXIMUM RATINGS (TA = 25 °C unless otherwise noted) PARAMETER SYMBOL VALUE UNIT Peak power dissipation with a 10/1000 μs waveform (1)(2) (fig. 1) PPPM 1500 W Peak pulse current with a 10/1000 μs waveform (1) (fig. 3) IPPM See next table A Power dissipation on infinite heatsink at TA = 50 °C PD 6.5 W Peak forward surge current 10 ms single half sine-wave uni-directional only (2) IFSM 200 A Operating junction and storage temperature range TJ, TSTG -65 to +150 °C |
