  • Low reverse leakage current of 1 µA at 5V
  • Low body height of 0.7 mm for ultra-thin designs
  • SZ prefix versions available for automotive AEC-Q101 qualified applications
  • Pb-Free, RoHS compliant, MSL 1

Aplicaciones

  • Voltage regulation in cellular phones and portable devices
  • High-density PCB power supply clamping
  • Reference voltage generation in compact instruments
  • ESD and transient protection for IC inputs
  • Automotive electronics (SZ prefix versions)

The onsemi MM5Z7V5T1G is a 7.5V Zener voltage regulator diode from the MM5ZxxxT1G series, packaged in the ultra-compact SOD-523 surface-mount footprint (1.2 x 0.8 x 0.7 mm). Designed for voltage regulation in space-constrained applications, the series covers a Zener voltage range from 2.4V to 75V. The device provides 500 mW power dissipation with ±5% voltage tolerance and features ESD Class 3 rating (>16 kV per Human Body Model). The low reverse leakage of 1 µA at 5V and Zener impedance of 15 Ω ensure stable regulation. The device is Pb-Free, RoHS compliant, and rated MSL 1 for unlimited floor life. SZ prefix versions are available for automotive applications requiring AEC-Q101 qualification and PPAP capability.

The MM5Z7V5T1G operates in the reverse breakdown region of its PN junction. When the reverse voltage reaches the Zener breakdown voltage (7.5V nominal), the junction enters avalanche breakdown, conducting current while maintaining a nearly constant voltage across its terminals. The Zener impedance of 15 Ω (maximum at IZT = 5 mA) represents the slope resistance in the breakdown region. The temperature coefficient of 5.3 mV/K indicates the Zener voltage increases slightly with temperature (positive TC for voltages above approximately 5.6V, where avalanche breakdown dominates). In forward bias, the diode conducts at approximately 0.9V at 10 mA. Power dissipation is limited to 500 mW at 25°C, with thermal resistance of 250°C/W (junction-to-ambient on FR-4 board). The device derates at 4.0 mW/°C above 25°C.
