ZSH5MAZ27 Description

Short technical summary and product information.

The Hitachi ZSH5MAZ27 is a surge suppressor diode engineered for robust protection against transient voltage events, particularly suitable for load dump surge protection in automotive electronic components. It offers a high transient reverse power capability, with a non-repetitive peak reverse one-cycle dissipation of 3400W (rectangular pulse, t=1ms) and a non-repetitive peak reverse surge current of 70A (exponential waveform).

Key electrical characteristics include a typical Zener voltage of 27V (ranging from 24.0V to 30.0V at 10mA), a dynamic impedance of 50Ω at 10mA, and a Zener voltage temperature coefficient of 0.081%/°C. The diode also has a peak forward voltage of 1.2V at 6A and a peak reverse current of 10µA at 22V.

Operating within a junction temperature range of -40°C to +150°C, the ZSH5MAZ27 is designed for reliability in demanding environments. The device has a storage temperature range of -40°C to +150°C and a weight of 1.5g. Its high transient reverse power capability makes it an effective solution for safeguarding sensitive electronics from voltage spikes.
