Taiwan Semiconductor SMF4LxCA/AH Transient Voltage Suppressor Diodes

Taiwan Semiconductor SMF4LxCA/AH Transient Voltage Suppressors (TVS) Diodes are high-efficiency, low-power, 400W, 5V to 75V surface-mount devices ideal for automated placement. These TVS diodes feature an excellent clamping capability and meet ISO 7637-2 (Pulse 1/2a/2b/3a/3b). The SMF4LxCA/SMF4LxCAH diodes are available in unidirectional and bidirectional configurations. These TVS diodes are RoHS-compliant and halogen-free devices with Moisture Sensitivity Level (MSL) Level 1 per J-STD-020. The SMF4LxCAH diodes are AEC-Q101 qualified. The SMF4LxCA/AH TVS diodes are ideal for automated placement and are designed to protect sensitive circuits from damage by high-voltage transients.
