SM4TY Automotive 400 W Transil Datasheet - production data Complies with the following standards ISO 10605, C = 150 pF, R = 330 : A 30 kV (air discharge) 30 kV (contact discharge) ISO 10605, C = 330 pF, R = 330 : K 30 kV (air discharge) Unidirectional Bidirectional 30 kV (contact discharge) (a) ISO 7637-2 SMA pulse 1: V = -100 V (JEDEC DO-214AC) S pulse 2a: V = +50 V S pulse 3a: V = -150 V S pulse 3b: V = +100 V S Features Description Peak pulse power: The SM4TY Transil series has been designed to 400 W (10/1000 s) protect sensitive automotive circuits against surges defined in ISO 7637-2 and against 2.3 kW (8/20 s) electrostatic discharges according to ISO 10605. Stand-off voltage range: from 5 V to 70 V The planar technology makes it compatible with Unidirectional and bidirectional types high-end circuits where low leakage current and Low leakage current: high junction temperature are required to provide 0.2 A at 25 C reliability and stability over time. SM4TY devices 1 A at 85 C are packaged in SMA (SMA footprint in accordance with IPC 7531 standard). Operating T : 150 C j max High power capability at T : jmax 270 W (10/1000 s) JEDEC registered package outline Resin meets UL 94, V0 AEC-Q101 qualified TM: Transil is a trademark of STMicroelectronics a.
