Zusammenfassung:The invention discloses a bidirectional electrostatic discharge (ESD) protection module which is integrated on a transceiver chip, the transceiver chip is provided with at least one output end and a grounding end, and the bidirectional ESD protection module comprises at least one transistor and at least one diode; when forward ESD stress is applied to the output end, ESD current flows through at least one of the transistor and the diode from the output end to reach the grounding end, and a first current release path is formed. When negative ESD stress is applied to the output end, the ESD current flows through at least one of the transistor and the diode from the grounding end to reach the output end, and a second current release path is formed; wherein the transistor is a PNP triode or an NMOS transistor, and the diode is a parasitic diode or an external diode of the transistor. According to the bidirectional ESD protection module provided by the invention, the bidirectional ESD protection of the transceiver
