The onsemi ESD5Z3.3T1G is a transient voltage suppressor (TVS) diode specifically designed to protect sensitive electronic components from electrostatic discharge (ESD) events. Housed in an ultra-compact SOD-523 package (1.2 x 0.8 x 0.7 mm), the device provides a working voltage of 3.3V, making it ideal for protecting 3.3V logic circuits and interfaces. The TVS diode clamps transient voltages to a safe level of 12.5V at peak pulse current (5.8A), preventing damage to downstream ICs. The device meets IEC 61000-4-2 Level 4 standards, withstanding ±15 kV air discharge and ±8 kV contact discharge. With 200W peak pulse power dissipation and low leakage current of 1 µA, the ESD5Z3.3T1G provides robust protection with minimal impact on system performance.

The ESD5Z3.3T1G operates as a bidirectional TVS diode. Under normal operating conditions (voltage below VRWM = 3.3V), the diode is in its off state, presenting high impedance with only 1 µA leakage current. When an ESD event or voltage transient occurs and the voltage exceeds the breakdown voltage (VBR = 6.5V typical), the diode enters avalanche breakdown, conducting the transient current away from the protected circuit. The voltage is clamped at VC = 12.5V at the peak pulse current of 5.8A (8/20 µs waveform). The device responds in nanoseconds, faster than the rise time of most ESD events, ensuring the protected IC never sees the full transient voltage. After the transient subsides, the diode returns to its high-impedance off state. The 200W peak pulse power rating indicates the maximum energy the device can safely absorb during a single transient event.
