Polarity 5.8 V to 459 V 5.8 V to 185 V 6.8 V to 540 V 6.8 V to 220 V 400 W, 300 W 3.3 W 40 A 150 °C Unidirectional, bidirectional Package SMA (DO-214AC) DEVICES FOR BIDIRECTION APPLICATIONS For bidirectional devices use CA suffix (e.g. P4SMA10CA). Electrical characteristics apply in both directions. FEATURES • Low profile package Available • Ideal for automated placement • Glass passivated chip junction • Available in unidirectional and bidirectional • 400 W peak pulse power capability with a 10/1000 μs waveform, repetitive rate (duty cycle): 0.01 % (300 W above 91 V) • Excellent clamping capability Available • Very fast response time • Low incremental surge resistance • Meets MSL level 1, per J-STD-020, LF maximum peak of 260 °C • AEC-Q101 qualified available - Automotive ordering code: P/NHE3 or P/NHM3 • 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, and telecommunication. MECHANICAL DATA Case: SMA (DO-214AC) Molding compound meets UL 94 V-0 flammability rating Base P/N-E3 - RoHS-compliant, commercial grade Base P/N-M3 - halogen-free, RoHS-compliant, commercial grade Base P/NHE3_X - RoHS-compliant and AEC-Q101 qualified Base P/NHM3_X - halogen-free, RoHS-compliant, and AEC-Q101 qualified (“_X” denotes revision code e.g. A, B, ...) Terminals: matte tin plated leads, solderable per J-STD-002 and JESD 22-B102 E3, M3, HE3, and HM3 suffix meets JESD 201 class 2 whisker test Polarity: for unidirectional types the band denotes cathode end, no marking on bidirectional types MAXIMUM RATINGS (TA = 25 °C unless otherwise noted) PARAMETER Peak power dissipation with a 10/1000 μs waveform (1)(2) (fig. 1) Peak pulse current with a 10/1000 μs waveform (1) (fig. 3) Power dissipation on infinite heatsink at TA = 50 °C Peak forward surge current 8.3 ms single half sine-wave unidirectional only (2) Operating junction and storage temperature range SYMBOL PPPM IPPM PD IFSM TJ, TSTG VALUE 400 See next table 3.3 40 -65 to +150 Notes (1) Non-repetitive current pulse, per fig. 3 and derated above TA = 25 °C per fig. 2. Rating is 300 W above 91 V (2) Mounted on 0.2" x 0.2" (5.0 mm x 5.0 mm) copper pads to each terminal UNIT W A W A °C Revision: 30-Jun-2021 1 Document Number: 88367 For technical questions within your region: [email protected], [email protected], [email protected] THIS DOCUMENT I.
