The ATV02W280B-HF is a bidirectional Zener transient voltage suppressor (TVS) diode manufactured by Comchip Technology. It is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). The device is AEC-Q101 qualified, making it suitable for automotive applications.
With a working peak reverse voltage of 28V, the diode clamps transients at a maximum of 45.4V when subjected to a peak pulse current of 4.41A (10/1000µs waveform). It can handle 200W peak pulse power under the same conditions, and up to 1000W for an 8/20µs waveform. The device operates over a junction temperature range of -55°C to 150°C.
The ATV02W280B-HF is housed in a surface-mount SOD-123FL package, which is molded plastic with UL 94V-0 flame retardant epoxy. The leads are solderable per MIL-STD-750, and the device is RoHS compliant and halogen free. Thermal resistance from junction to ambient is 200°C/W, and junction to case is 100°C/W.
